Vulpine Confession #10:

"It's all for SCIENCE!"

A scientist vixen undertakes the most erotic of "sexperiments" and recruits new experimental subjects: Her own innocent teenage daughters.

"I need you two to have sexual intercourse with a row of anonymous strangers, right in front of me, while I take notes." she told them.

(F.Y.I.: All vulpines involved in adult situations are intended to be 18 fox-years old or more....)

Hello, there! My name is M****** R**. (Due to the nature of the story I am about to tell you, I would prefer to remain anonymous.) I am a happily married red fox vixen in my early forties. I have always been a loyal wife and I would never, ever dream of cheating on my husband. What I am about to tell you had nothing to with cheating! I did what I did strictly for SCIENCE! No amorous feelings were involved!

My kits have now grown up and become young adults, and I have finally time to fulfil a lifelong ambition of mine. I have gone back to studying vulpine medicine, and I hope that l soon will become a fox doctor.

I'm almost done with my medical training. I just need to submit my master thesis before I can practice as a physician.

Due to my background as a nurse/midwife and also some recent, rather embarrassing personal experiences, I have become something of a sex expert. No wonder that I decided to conduct a special study of vulpine sexuality.

Initially, I performed experiments on my own body. I got some satisfying test results, but I realized that I would need to recruit other vixens as test subjects in a control group.

Even though I have given birth to three kits, I still have the firm body of a young foxgirl and I have often been mistaken for one of my teenage daughters. Yes, I thought, my daughters would be the perfect candidates to participate in my study. I decided to ask them to volunteer, but I was unsure how they would respond to my proposal...

Anyhow, I called my daughters and asked them to meet me at the vulpine hospital.

"Come here at once, girls! I need your help with something..." I said.

"What is it? Is it a medical emergency? Has some fox we know had an accident?"

"Don't worry, it's nothing like that! It has to do with my studies, but I don't know how to explain it over the phone. It is kind of embarrassing! I'll see you in the lab."

I was very embarrassed when I sat down with my girls over a cup of coffee in the doctors' den.

"As you kids know, I was working as a nurse when I met your father, but I always wanted to become a doctor. Now that you have grown up and moved out of the family den, I have had time to continue my education. I am now just one step from my goal, but I need your help to pass my final exam. Would you like to help me with a little scientific experiment?"

"Sure, mom! What is it?"

I hesitated before I answered,

"It is a study which would require nudity on your part. Are you okay with that?"

My daughters looked at each other, and giggled. One of them finally answered,

"Well, none of us are afraid of some casual nudity, but I guess it would depend on exactly what we are talking about.

"I need you two to have sexual intercourse with a row of anonymous strangers in front of me, while I take notes." I said.

My daughters gasped in unison, feeling extremely uncomfortable. They couldn't believe their cute pointy little ears!

"MOM! You want us to do WHAT?!" my daughter R******** exclaimed.

"You heard right! But I'd better explain it in a language that you understand."

I looked at my daughter and said,

"The experiment will measure the arousal level you experience while being repeatedly fucked by a number of anonymous cocks in several different positions."

"EWW! GROSS!" she replied, feeling extremely uncomfortable.

"It's part of a little experiment I am running, a study of vulpine arousal. I want to see exactly what makes you aroused, and that will help me as I study vulpine sexuality.

"But we are not THAT kind of foxgirls! You know that we are saving ourselves for marriage, just like you did!"

"I know, dear! Do not worry; you would still be considered virgins afterwards. This isn't for your pleasure, it's for science!"

"I can't believe this! HOW did you come up with this idea? WHEN, WHERE, HOW, and WHY?"

It was my turn to feel extremely embarrassed.

"A while ago, when my nephews - or your creepy cousins as you use to call them - accidentally had sex with me..."I answered.

"Apparently, the creeps mistook me for one of my daughters. I was leaning out through the open window, when one of the creeps snuck up behind me, pulled my shorts down, and inserted his erect penis in my vagina from behind! Shocked, I froze stiff and just stood there while my horny nephew had his way with me. Before I had time to react, he pulled out and was replaced with his brother!

"We know that, mom! We caught you in the act, remember? The little creep was still inside you when we walked in on you! You explained that your nephew had taken you by mistake and you made us promise to forget that it ever happened!"

"Anyhow, both of my nephews had sexual intercourse with me! I couldn't help noticing how different they felt inside me, compared to each other and specially compared to your father. They all have similar equipment, but and felt quite different! They used different techniques. This called for further investigation! I know I had to give the creeps another test ride!"

"But, MOM! You are not THAT kind of vixen! You are happily married, loyal wife!"

I averted my eyes. I couldn't look my innocent daughters in their eyes.

"I know, but... It wasn't about sex! It was merely a scientific experiment to see how a vixen would react to another cock than her husband's inside of her married pussy! The creeps had already been inside me, so the damage was already done. They couldn't un-fuck me, but they took turns in inserting their cocks in my love-canal, so that I could compare them to my beloved husband's!

Yes, I have already conducted a series of experiments with your cousins! They used my body in every way possible and I got plenty of satisfying test results, but I now need a control group of fresh vixens to verify my results. Your cousins have gained valuable experiences during the early experiments, so they will continue to play their part in this experiment."

I finally dared to face my daughters.

"I suspect that you aren't virgins anymore. Your cousins said that they mistook my sexy little foxbutt for one of yours, so assume that they have had sex with both of you earlier?"

"Perhaps... We might have had sex... We don't know for sure!"

"What do you mean? Unless the creeps took advantage of you while you were asleep, you must know whether they had sex with you or not!"

"Well... You see, mom... It happened like this... We might have mentioned to our cousins that we were curious to know what it would feel like to be vaginally penetrated by a penis, and they generously offered to help us out.

It happened so fast! Suddenly, they pulled out their rapidly growing dicks and lifted our short summer skirts. It was a hot summer day and we had nothing on beneath. Before we had time to react, our cousins' rapidly hardening cocks were buried deep inside of us! To our surprise, it didn't hurt as much as we had imagined. It actually felt rather good, and the whole thing was over in a couple of seconds.

Our cousins just gave us a couple of quick pokes each and they made sure to pull out before they got knotted and tied with us! We had experienced our first proper vaginal penetrations, but our cousins told us not to worry, we would still be considered virgins, as three strokes or less wouldn't count as sex. We haven't let them touch us since."

"I see... Do you think about your cousins when you masturbate?"

"Yes... All the time...."

"How often do you masturbate? At least once a day?"

"Oh, yes! And, at the very least, twice a day during mating time!"

"Okay... Do you insert.... objects inside your vaginas during masturbation?"

"What kind of 'objects' do you mean, mom?"

"Well... you know... the usual things. Sausages, bananas, cucumbers and stuff..."

"Oh yes, we have tried those! Whew! And here I thought you meant something weird , like baseball bats or something!"

"Good! You would have no problem with letting your cousins penetrate your nearly virgin vaginas then! Have you ever fantasized about having sex in public?"

"Well... sometimes..."

"Good! I will have to monitor your arousal for the duration of the experiment. Have you ever been filmed during sex before?"

"NO! Never ever! What kind of vixens do you think we are?!!"

"I will take some pictures and video tape you, but do not worry! Your confidentiality is assured. No one but your cousins and I will know your true identity."

"But, what if those vids and pics get in the wrong paws and end up on the internet! The shame would kill us!"

"Trust me, girls! There's no way those pics will ever find their way to the Internet. No way!"

"Our creepy cousins will find a way!"

"You don't have worry about that! You see, this will be a blind test, so you will be wearing blindfolds the whole time. You will not be able to identify the owner of the penis that is inside your vagina, but I on the other hand, no-one will recognize you! You will be completely anonymous the whole time."

"But... If we were blindfolded, they creeps could use our bodies as they pleased. They could fuck us as hard as they wanted, and use us in whatever way they wanted. Oh my God! They could even recruit help from others! They could invite all their friends use us!"

"Don't worry, girls! Nothing bad will happen to you! I will be watching over you all the time! I will not ask you to do anything you do not want to do, and you are free to quit anytime you feel uncomfortable. Okay? One final question: Have you ever fantasized about having sex with a member of a different species?"

"MOM! Of course not! Inter-species sex is SICK and DISGUSTING!"

"Your own aunt is married to a leopard! You don't think that they are DISGUSTING, do you?"

"No, but.... EWW!"

"Ever since my sister married a leopard, I have always wondered what it would be like to it with a feline... Perhaps I could convince him to take part in this study. Wouldn't you like to try something new?

"NO! God, NO! Not with him! Not with Uncle Leo!"

"Okay, if you don't want to have sex with an actual leopard, I have another proposition for you. I have acquired plastic replicas of a variety of animal penises. Feel free to use them as much as you want. I even got a HUMAN penis in my collection, but that thing is HUGE! It would never fit inside your near virgin vulpine vaginas!"

"Probably not, but did it fit inside of YOU, mom? You tried it for size, didn't you?"

"Why, Yes. Yes, I did! I have always wondered what it would feel like to be impaled on a human penis!"

One of my daughters picked the obscenely shaped dildo from the shelf behind me. The girls examined the enormous latex dildo and marveled at its length and girth. It was an accurate depiction of a human penis, complete with a realistic looking glans and prominent veins! The foxgirls had no idea what a human cock actually looked like in real life, but to them it looked magnificent. They couldn't help wondering what it would feel like to have sex with a real human being!

"OH!" one of the girls gasped "This thing is longer and thicker than my forearm! OH MY GOD! The cock-head is larger than my clenched fist!"

"Are male humans really this big?" her sister asked. "If that is the case, I feel truly sorry for their females. No wonder that human girls walk funny!"

"Oh yes! All humans have huge ones! I am told that this is a representation of an average human penis. Whatever you do, DO NOT try to put it inside your tight virgin vulpine vagina! I was lucky enough to survive the attack of the human cock, but I sure walked funny for a couple of weeks..."

"It must have been a unique experience! Do tell us all about it!"

"Only if you promise not to tell anyone else what happened!"

"Of course not!"

"The obscenely shaped dildo was so big that I had to warm up with a number of smaller dildos. I rode bigger and bigger ones until my vagina was dripping wet and I was ready for the grand finale!

I lowered myself onto the big human cock, as slowly as I could. The head of the huge dildo pressed my labia apart and I could barely hold back from screaming as my tight vagina was widened unnaturally. It DID hurt a bit, but it hurt so GOOD! I had never experienced anything so erotic in my life.

As you know, foxes like to study things rigorously and as deep as possible, and I'm no exception. My body, acting on its own, began bouncing on the plastic cock. It was an incredibly tight fit, so I could just barely get the head of the cock inside me.

Suddenly, the cock slipped out of my vagina and pressed against my well-lubricated anal opening! As I bounced down, the head of the massive cock stretched my anus wide open and forced its way inside. It slipped right through the sphincter and entered my tight virgin poop-hole. The sudden pain made me twitch. As I stumbled and fell backwards, the thick shaft pushed all the way inside my poor little foxbutt!

I was screaming with fear and intense pain, imagining that the monster dick had wrecked my intestates and created a bloody mess! I thought that this was it! I was sure it that I was going to die, impaled on that human penis! It felt so long and seemed to fill me up past my belly button!

Vixens who say that size doesn't matter have never been fucked by a HUMAN dick. It went so deep inside me, so very DEEP! I could feel it rearranging my internal organs, and it felt like the tip was going to come out of my mouth! I was grateful that the cock had an enormous pair of balls at the other end; otherwise the head would have drilled its way right through my petite body!

It was an incredibly tight fit, it did hurt a bit, but the sensation to sit on a huge HUMAN cock was fantastic. I was sure that the huge cock was going to make a mess of my intestates and kill me, but at that moment, I was the horniest vixens on the planet. There was a pleasurable feeling of fullness like no other I had ever experienced, and I had the most powerful orgasm I'd ever had. I couldn't believe how long I came for, before I passed out in orgasmic bliss.

When I woke up, with the hard, rigid human cock buried balls deep inside me, I was afraid to remove the huge shaft from my stretched anus. I thought that my wrecked intestates would fall out of the gaping hole that the huge human cock had drilled beneath my tail. It hurt like hell when I managed to dislodge the cockhead from my aching butthole, but I was a lucky vixen. I didn't get any permanent damages in my little foxbutt.

I still can't believe that I have had a HUMAN penis buried deep inside of me! I had gained an interesting experience, but I don't want to repeat it ever again! At the same time, I can't help wondering what it would feel like to have sex with a REAL human being, but some things should be left to the imagination. No more human monster cock for this vixen!

But, I am digressing... Well, what do you think about my proposal, girls? Are you up for it? Did I mention that you will get well paid?"

"Are you really going to pay us for sex with our cousins?"

"No and no! I will not pay you, but the hospital will. And you will not have sex exclusively with your cousins. There are actually some other male test subjects."

"You must be kidding! Dare we ask who else you have sold your innocent little daughters to?"

"The male doctors at the hospital kindly volunteered to help me with the study."

"Do we really have to fuck them, too? Some of them are old enough to be our grandfather!"

"Come on, girls! Don't let your feelings get involved! It's all for SCIENCE!"

After some coercing, both of the girls reluctantly agreed to become test subjects.

After a quick shower, they emerged from the locker room wearing nothing but bath towels wrapped around their foxy little bodies. I put blindfolds over their pretty eyes and lead my daughters to the sex lab, where the male test subjects already were eagerly waiting for them.

The towels were on the small side. The butt cheeks were just slightly peeking out from under them, as my daughters walked down the corridor. Not that it mattered much. The towels weren't supposed to stay on for long!

When we reached the lab, I removed the towels.

"Are you ready to engage in coitus, girls?" I asked.

"Well, I'd guess so," my daughters replied in unison.

I asked my naked daughters to bend over the examination table and raise their tails. Both of the girls were already dripping wet with excitement, so we could skip the foreplay and save a lot of time! Within seconds, their little foxholes were stuffed with a hard cock!

To the girls' great surprise, the cock-owners didn't start to fuck them immediately. They stopped with just the tip inside the girls and waited for permission to continue.

"As you may have noticed by now, the male test subjects are very well endowed. Since you girls practically are virgins, this will just be an initial test to determine if you are suitable subjects for this study. All the male test subjects will put their penis inside you, one after another, just to see if they fit inside your tight, inexperienced vaginas. Are you ready for your first test ride?" I asked.

"Yes, I guess so... But... Wait... aren't they supposed to wear condoms?"

"Sorry, but this will be a bareback ride! The use of condoms would ruin the entire experiment! You wouldn't get the right FEELING if they had condoms on! We may test different kinds of condoms later on in the study, though."

One of my daughters had some reservations.

"Mom! You can't let them do this to us!" she gasped. "Things are going to get out of hand. What if we get pregnant?"

"Don't worry! You could always take the day-after-pill!" I said.

The male test subject pulled his cock out of my daughter. He leaned forward and whispered in her pointy ear,

"You know, we could always use your poop-holes as loop-holes. This study is not complete until you have been properly filled in all of your holes, anyway..."

Her body shuddered when she felt the stranger touch her most intimate spot. I looked at the tip of his penis and saw that it had collected some liquid from her pussy. It was wet enough to slip inside her poop-hole at the first try.

"PLEASE NO!" she screamed as she felt the cock invade her bowels.

"No one has ever done that to me, please don't...stop", she whined as cock owner began to thrust. He went deeper and deeper for each thrust.

Suddenly, someone snuck up behind me, grabbed the hem at the bottom of my lab coat and flipped it up over my head! I was always ready for action during my "sexperiments", so I wasn't wearing anything beneath my lab coat. My bare foxbutt was his to use as he pleased.

"No!" I said, as I felt a hard penis slip inside me. "NO! Not today! I am trying to observe my daughters and take notes! It isn't easy to concentrate at my task, while being fucked from behind!"

I was silenced by a big fat cock showed deep down my throat.

"How else do you expect us to compare you to your daughters?" the cock-owner said. "Don't bother to take notes; you can always interview the girls afterwards! Besides, everything that happens here will be available on video tape!"

Strong paws removed my lab coat, and I found myself completely naked, like my daughters! Actually, I felt even more naked, as both of my daughters had blindfolds on. Everyone could see the excitement in my eyes, as I became spit roasted next to my daughters.

Suddenly, one of my daughters screamed loudly.

"OH! Oh, Nooooo! I can't believe what you just did to me! You came inside me! I was saving myself for marriage! How can you treat me like this?"

"Don't worry! I came in you cute little asshole, so you are still - nearly - a virgin! A vixen hasn't been fucked properly unless she's got a load of sperm in her pussy!"

Over the next couple of hours, a seemingly endless row of anonymous cocks entered my wet vulpine vagina before moving on to one of my daughters' tight little holes. All of the test subjects put their cocks inside me at least once, but they all saved their sperm deposits for my daughters.

When the males test subjects had had enough, they had already brought my daughters to multiple orgasms, but they had left me unsatisfied. One of my creepy nephews had a solution, though. He fetched the human shaped dildo, lubed it up, and placed it in the middle of the floor. The huge head seamed to reach half-way to the ceiling.

"Here you are, Auntie M! It's lubed and ready for you! Have a nice ride! Satisfaction is guaranteed!" the creep said with a wide smile on his face.

"You must be kidding?!" I asked. "That is a HUMAN penis! It is HUGE! It will never fit inside my tight little vulpine vagina!"

"Don't be like that! You don't know if it will fit until you have tried it for size!"

"You don't understand! I have already tried it!" I whispered. My shame was killing me.

"Oh, really? Well, try it again, then! I insist!"

"Thanks, but NO thanks! No more human cock for this vixen!"

The creep addressed the other male test subjects.

"I really think she should try it!" he said. "We should offer her some help with that, don't you think? Who else want to see her ride the human cock?"

The male test subjects suddenly grabbed my arms and legs! With my legs spread wide, they carried me to the middle of the room. This had the effect of spreading my pussy lips apart, too. Before I had time to react, I found myself hovering over the big human penis, with my wide open vulpine vagina just centimeters over the cock-head! The creep aimed the head of the enormous latex dildo for the entrance of my little opening.

With my legs spread obscenely wide, I was lowered down on the human cock. I panicked, as I felt the huge head of the human penis at the entrance of my tight little vulpine vagina! I was kicking and screaming!

" Oh God NOOOOOOO!" I shouted "You can't do this to me! It doesn't fit. It's too big! Too BIG!"

My daughters wondered what was going on and removed their blindfolds. They dropped their jaws as they saw me on top of the enormous latex dildo with my pussy-lips wrapped around its bulbous head.

With my legs spread obscenely wide, I felt truly exposed and helpless. I knew my entire body must be blushing from the embarrassment of being in such a compromising position, I could only hope that it wasn't visible through my already red fur. Not that it mattered if it was; I had much worse problems...

The thick head of the huge dildo pressed my pussy-lips apart and my daughters watched fascinated as my wet vagina began to swallow the dildo. The creep asked my daughters,

"What do you think, girls? How much human cock do you think that your mother can take? I guess that she can take more than half of the shaft! She is an experienced vixen, you know!"

My daughters were mesmerized by the sight of my stretched pussy as it was swallowing the huge toy. They watched as the whole dickhead disappeared inside me.

"Well... She did say earlier that it once went all the way inside her little poop-hole," one of them whispered.

" All the way to the balls ," the other one whispered.

" To the balls , you say?" the creep asked. "Okay, boys! You heard what the girl said! Let's see if her mom can take a human cock balls deep in her little foxhole!"

"OH NO! No, I can't possibly... I CAN'T!" I yelled. " That thing is HUGE and I'm not hollow!"

It already felt like my entire vagina was full, like every inch of me was being stretched to the limit. There just wasn't any more room inside me for cock!

"AH! OOOOOOOHHHHH!" I moaned as the male test subjects abruptly lowered my body and the thick shaft pushed deeper inside my vagina! Almost half of the long, thick shaft went inside me in one thrust!

The males were repeatedly lifting and lowering my body on the dildo, first slowly then faster and faster! I was helpless as I went up and down, impaled on the thick shaft, but I couldn't help thinking that the whole thing was partly my fault!

"How could I ever have expected the male test subjects to behave properly in the presence of three gorgeous, naked vixens?" I wondered.

Whatever I was feeling, it was too late to change things. I was being fucked hard, right in front of my innocent daughters! I might as well try to enjoy it!

I could feel strong paws caressing me all over my body as they forced me up and down on the giant cock. For some reason, I became incredibly wet, which made that big human penis slide deeper and deeper into my tight little love canal. I could feel the head banging against my cervix on every thrust. Eventually, most of the big plastic dick was swallowed up into my soaking wet pussy with each stroke.

"Look at your mother, girls!" the creep said. "Look at the way she's taking that huge human cock! It almost completely disappears inside her little foxhole!"

"We can't look at her!" one of my daughters said. "Just the sight of mom's stretched lady parts makes our own little pussies hurt!"

"You are hurting our mother!" my other daughters said. "Please let her loose!"

"Don't feel sorry for your mother, I'm pretty sure she secretly enjoys it! Just look at her! That vixen's face says: 'Damn it! I should so not be enjoying this!' "

I turned my head away. I couldn't face my innocent daughters.

The creep was right, you know. To get impaled on the monster dildo did hurt a bit, but much less than I had expected, and was actually beginning to enjoy it! I was still afraid that the huge human cock would destroy my little vulpine vagina, and forever ruin me for my husband. But on the other paw... If my lady parts actually got broken, I was surrounded by competent surgeons that could surgically reconstruct it!

"Don't worry, girls!" the creep said. "We are almost done with your mother! As soon as her butt touches the balls at the base of the plastic cock, she will be free to dismount it, if she wants."

"You are almost there," he told me. "If it doesn't hurt too much, try to go down a little further... Just a little bit down..."

The huge set of balls at the base of the dildo was almost within reach. I still had about five centimeters to go before I would reach my goal, though. The inpatient creep decided to help me. His strong paws grabbed my hips from behind and forced me all the way down to the base of enormous latex dildo!

I could barely hold back from screaming as my tight vagina was stretched unnaturally.

"Too much!" I hissed, through gritted teeth. " Too much! Ahhhh!"

I was being stretched out more than I ever thought possible. It felt like the monster dildo was rearranging my internal organs, and when I looked down I could see it bulging out my stomach obscenely. Never had I experienced such mixed emotions. I was horrified, but excited at the same time. It hurt a bit, but much less than I had expected.

"Just a little further down," the creep said, "Just relax and let it happen!"

The enormous latex dildo was filling my entire vagina, pressing hard against my cervix, but there was still at least a centimeter of cock left. The creep kept pushing me down on it.

"Come on, Auntie! Keep going, take that cock all the way!" the he said "You can do it, you're almost there! Try to relax! That's it, just like that!"

The creep forced me down even farther until finally my furry little foxbutt made contact with the balls!

I gasped as I felt the balls brush against my furry butt! The creep had managed to push me all the way down to the base of enormous latex dildo. The huge human penis was now stretching my pussy and entering depths didn't know existed!

"That's it, Auntie! All the way to the balls!" the creep exclaimed. "Good girl! I knew you could take that human cock all the way! That's so fucking hot!"

At my first attempt, I could barely get the head the obscenely shaped dildo inside me, but I could now take the whole thing in with ease! The pain gradually began to turn into pleasure as the male test subjects kept moving me up and down on the cock, faster and faster for each stroke.

I began to feel familiar tingles all over my body. I could hardly believe it, but was at the verge of an orgasm! A BIG ONE! I quivered uncontrollably. The boys let go of me and I began to bounce up and down on the plastic cock in my own pace. I was now happily humping a huge human cock in front of my own daughters!

The male test subjects chanted,

"Fuck that cock! Fuck that cock! Fuck that cock! Fuck that cock!"

Not that I needed their encouragement. By then, I was so aroused that I could take the whole cock with ease!

" Look at your mother, girls!" the creep exclaimed. "Look at the way she's taking that huge cock! Oh, yes! She just loves that human monster cock! OH, YESSSSSS! Look how she is climaxing, impaled on that human cock! Oh, what a naughty vixen she is! Look, girls! Your mom is cumming! SHE'S CUMMING!"

The creep's remark put me over the edge! With a loud moan I started to cum! My poor vagina, stretched by the massive phallus, was wracked by continuous spasms as the orgasm consumed me. My orgasm seemed to last forever! It just went on and on! My face was contorted by a mix of pain and pleasure as the screams of my orgasm echoed in the room.

"Ohhh.....yes....yes....yes.....Oh, YESSSSSS!" I screamed as my body was tossing and turning in the most powerful orgasm I ever had in my life. My vagina was violently contracting around the dildo. It popped out of me and flew away like a rocket!

When the plastic cock popped out of me, it was met by thunderous applause from the males, and worried looks from my daughters. They couldn't believe that most of that huge human dick had been inside their mother!

As I finally came down from my orgasm, I was just lying on the floor like a rag doll.

"Mom...? Are you okay?" one of my daughters asked. "What was it like to sit on a huge human penis? Did it hurt much?"

"It's... a feeling... that's impossible... to describe," I panted. "I can't believe... how far... my poor... vulpine vagina... is stretched! But... it doesn't hurt ...much."

I was a bit sore downstairs, but after a thorough examination of the gaping hole that the huge human cock had drilled between my legs, the doctors assured me that I hadn't suffered any permanent damages to my private lady parts. When I had composed myself I inspected my daughters little bodies.

Things really had gone out of hand! With exception for their near virgin vaginas, both of my daughters had received huge loads of cum everywhere. I mean EVERYWHERE! It covered most of their fur. It dribbled from the corners of their mouths, and even from their ears! It was dripping from their anal openings.

I urged the girls to hit the showers, before their cum-stained fur dried. Otherwise, they would have to walk around with the visual evidence of their escapades in their fur for days!

After the shower, I asked my daughters if they dared to come back for another round.

"Well...We might..." R******** answered. "This was certainly an INTERESTING experience. We learnt a lot about vulpine sexuality today!"

I picked up my note-book and began to take notes.

"Interesting, you say? Exactly, what did you learn?" I asked.

"We could never have guessed that the cocks would feel so different! All the cock-owners had different techniques. Some of them fucked us agonizing slow and others fucked us fast and furious! Some of them used short stokes and others used long strokes. Some pushed in fast and pulled out slow, others did it the opposite way!"

S******** blushed so heavily that it was visible through her thick facial fur, and confessed,

"One of males even turned me around and fucked me in the perverted missionary position. He had a huge cock, and I pretended that I was ravaged by a human monster!"

Her sister giggled,

"Oh yes! That happened to me, too! That was kind of HOT! Inter-species sex may be considered sick and disgusting, but to pretend that I had sex with a human actually turned me on beyond belief! I wonder what the guys will come up with next time!"

"You don't have to wonder! Can you come back the same time tomorrow?" I asked.

"Oh, no! Noooo! We just had the sex session of a lifetime! It felt great, but our sore little foxbutts will need some time to recover! We might come back and help you with your science project later on, though!"

"I'll see you here next week, then?"

"Perhaps..."

My daughters smiled happily at me as they left. They both carried a glow of satisfaction and I knew that they would come back soon for some more "science"! Perhaps I could persuade them to participate in some inter-species intercourse the next time, I thought.

P.S.

All of this happened some time ago. I have now passed my final exams, so I don't need help from my daughters anymore, but I believe that they still are experimenting with their creepy cousins.

I don't want to keep secrets from my beloved husband, so I told him everything that happened. I even showed him the video recordings. Luckily enough, my husband is very understanding.

He thinks that my new experiences have greatly improved my lovemaking skills, so he has nothing to complain about. He says that while I always have been great in bed, I have now become a wild animal and an AMAZING mistress!

P.P.S.

The huge, obscenely shaped dildo mysteriously disappeared from the sex lab, so I never got a chance to ride it again. (Ah, well... That thing was too BIG to keep comfortably using, anyway.) I later found out that my creepy nephews had given it to my daughter-in-law as a gag gift, just to make her blush!

The enormous dildo was an inappropriate gift for a modest, married vixen, and the little creeps knew it! They did what they did for SCIENCE! They wanted to see if they could make a vixen blush so hard that is was visible through her red fur. (And yes, amazingly enough, it was!)

Oh yes, my creepy nephews are truly uninhibited about sex. They like to tease girls, and make them feel uncomfortable, but they are harmless, most of the time. No, they couldn't resist me and my sexy little foxbutt, but they aren't the kind of foxes that are roaming the countryside in search of innocent young vixens to ravage. My poor daughter-in-law is probably safe, at least for now, but I'd better keep an eye on her in the future.

P.P.P.S.

The monster dildo is still missing in action! I never found out what my daughter-in-law did with it, but suspect that she carried out some scientific "sexperiments" on her own. As you know, we foxes like to study things rigorously and as deep as possible, and she's no exception. She may be shy but she still is a hot vixen. You know what I mean! *Nudge, nudge!*

P.P.P.P.S.

As you already may have guessed, the male doctors and I still conduct some "sexperiments" on quiet nights, when business is slow at the hospital. All for SCIENCE!

Do you want more vulpine naughtiness? Of course you do!
