On the evening before her wedding, Bonnie decides to head over to her twin brother's apartment to finally tell him how she feels about their relationship.


(Hedgehog Couple...Brother/Sister)

Tomorrow is my twin sister's wedding and as I sit in my single bedroom apartment, I can't help wondering what she's doing on the night before she marries that fox boy from Yokai City. I figured that she would be out with her friends, probably having some sort of bachelorette party, possibly even going out to a sex club that catered exclusively to female clients. This concerned me some as I sat in my chair, thinking about my sister. Bonnie has always been important to me, we've been close to one another ever since we were young. When we were younger, I would act as my sister's protector, doing whatever I could to keep her safe from anyone who would treat her badly. That's why it took Bonnie so long to find a mate that I could approve of. Now, I was worried with my twin sister out on the town that she'd come across a male who wanted nothing more than to get into her panties.

It made me upset that I wasn't with her, making sure to protect Bonnie's honor and making sure that no one tried to make any advances on her. All I could do was sit on my butt and think about what might be going on, making me shudder with thoughts of some random male making out with my twin sister. However, as I sat in the chair thinking, I heard someone knocking at my apartment door.

"How could that be?", I wondered curiously, not expecting anyone to come to my apartment this evening. I got up from my chair and walked to the door, peeking through the spyhole inside. To my surprise, it was Bonnie, wearing a black evening gown and the diamond earrings our parents gave her as a birthday present when she turned 18. She was also wearing ruby red lipstick and looked as if she was going to go out on the town, which made me wonder even more why she happened to visit me.

Nevertheless, I opened the door and was quick to greet my twin sister. "Bonnie! What brings you here?", I asked curiously before she looked at me with her pretty blue eyes. My sister was a natural blonde, which went well with her peach-colored facial and body fur. She took more after our mother in terms of appearance while I looked more like a traditional hedgehog.

"My friends wanted to take me out to a sex club tonight, but I didn't want to go. I don't feel like having meaningless sex with a random male that I don't have any attraction towards", Bonnie replied as a wave of relief washed over me.

"Oh, Thank God! I was worried sick about that!", I replied as Bonnie looked at me with a smile.

"Can I come inside? There's something I'd like to talk to you about", she asked curiously.

"Of course! Come on in, Bonnie", I answered happily watching as she entered my apartment, safe and sound. "Can I get you anything to drink?", I offered politely as she had a seat at my kitchen table. Even though I lived alone, my kitchen table had four chairs at it for when I had visitors.

"No thanks, I'm good", she replied before I sat down at the table across from my twin, still a bit curious to know why she decided to come see me.

"So, what's up?", I asked a few moments later as Bonnie started to blush a little and looked a bit shy.

"Adrian, do you love me?", she asked curiously as I looked at her.

"Of course I do! You're my twin sister!", I started to answer, somewhat surprised by her asking me this, with me thinking that it should be obvious based on how I treated her. "Aside from Mom and Dad, you're the most important thing in my life", I added as Bonnie looked at me while blushing some more. "What makes you think that I wouldn't love you?", I asked.

Bonnie then reached out to me, touching my hand with one of hers. "Well, nothing really...but there is something that I've been thinking about for a while now and since I'm getting married tomorrow I was hoping that you could do something for me before my wedding", she answered, softly stroking my hand with hers.

I was a bit curious, so I decided to see what she wanted. "OK, what do you want me to do?", I asked softly.

Her cheeks turned bright pink and she started to feel a bit on the nervous side, continuing to caress my hand gently. "Well, you know how I told you that I didn't want to have sex with a male that means nothing to me? That didn't mean that I'm not interested in making love with someone on my last night of bachelorette freedom. I just want to do it with someone who makes me feel happy, someone that I trust", she replied as I suddenly realized what she meant.

"Bonnie! Are you saying that you want to have sex with me?", I replied, surprised by my sister's comment. She kept blushing and took hold of my hand.

"Why not? Lots of sisters do it with their brothers at some point in their lives. Besides, haven't you ever had any thoughts about me that way in the past?", she answered calmly.

I blushed and felt a little nervous. I didn't want to admit it when we were younger, but I did feel some attraction towards Bonnie. "Well...maybe...but I don't know if I could. I mean, you're going to get married tomorrow and I don't know if I would feel right about doing it", I explained to my sister. "Besides, what would happen if we had sex and you got pregnant?", I added.

Bonnie chuckled and rubbed my hand a bit more. "Quite honestly, I wouldn't mind having your babies", Bonnie answered, making me feel nervous for a moment. "However, you don't need to worry about that. I had uterine caps placed inside me, remember", Bonnie added as I remembered back to when Dad insisted that Bonnie have the caps put in to prevent pregnancy until she met her future husband.

"I'm having them removed as soon as Koji and I get back from our honeymoon. So, if you want to fill me with seed, you should do it now while you have the chance", Bonnie continued.

Hearing her mention this made me think about what Koji would say if he knew I had sex with Bonnie. Koji was like a slightly younger brother to me, a twin-tailed yellow-furred kitsune male with a gentle and generous personality. We would often play online games together, working as a team most of the time, or just having a bit of competitive fun. "But, what about Koji? What would he think of this?", I asked.

Bonnie giggled and kept stroking my hand with hers. "You haven't met Miyako, have you?", Bonnie playfully commented. "You see, Koji has a twin sister of his own, Miyako. They've had sex together too and I don't mind...although it does help that both me and Miyako are bi", Bonnie continued as I suddenly saw a glimmer in her eyes. "Hey, you should get together with Miyako! Aside from Koji, she's not seeing anyone right now and I'm sure she'd want to go out with you", Bonnie sweetly suggested, knowing that I lived alone.

"Well...I don't know, Bonnie", I replied, unsure of how to feel about a female I didn't even know.

"At least give it a try, Adrian. Besides, I gave Koji permission to keep seeing his sister from time-to-time when he told me about Miyako. If you and her start to go out, I'm sure Koji would be willing to let us play together on a more regular basis...that is, if you want to stick your dick in me", she explained before I felt Bonnie take my hand in hers and hold it tightly. "Please have sex with me tonight, Adrian. I really want you in me. Plus, you'll be able to get laid without having to pay someone money to do so", Bonnie continued, knowing that I have been to sex clubs in the past.

In all honesty, I was in the mood for sex. It had been close to a week since the last time I got my rocks off to a live female and I felt a bit pent-up down there.

"Mmm...alright...I'll give it a try", I replied curiously, already starting to feel my maleness growing erect inside my pants.

"Mmm...good", Bonnie soon answered. "So, should we go into your bedroom or do you have somewhere else you'd like to do it?", she asked curiously, seeming eager to play with me.

"I think the bedroom will be fine, Bonnie", I replied, preferring the bedroom over somewhere like the living room. After this, I got up from my seat while Bonnie and I kept holding hands, with me going to stand next to her. She then kissed my cheek in a loving manner, getting her lipstick on it.

"I'm so excited right now! I can hardly wait to feel my cute twin brother inside of me!", she replied eagerly, causing me to blush some before the two of us made our way into my bedroom.

Once we were in the bedroom, Bonnie kissed my cheek a second time, leaving an additional kiss mark on my cheek. "Why don't you take off your clothes and get comfortable on your bed", she suggested.

I wasn't sure exactly what Bonnie had planned, but I went along with it, taking off my shirt and pants, letting them drop to the floor. Soon after this, I removed my boxers, allowing my 7 1/2" long penis to have some breathing room. It was nearly fully erect, having grown stiff as I felt Bonnie's hand on my own and her kisses to my cheek.

Bonnie got a look at what I had and giggled playfully, giving my shaft a loving grope. "Mmm...not bad", she playfully commented, stroking my length a little to help it reach full arousal. "Anyway, go ahead and hop in bed. I'll join you in a moment", she added, making it seem like she knew exactly what she wanted to do.

I wanted to please my sister, so I followed her instructions, getting onto my bed and relaxing, lying back on my pillow as I started to see her undress. She first removed her nice evening gown, placing it on the back of my computer chair so that it stayed relatively nice and neat. All she wore underneath the evening gown was a pair of black panties. Bonnie didn't even wear a bra underneath the dress, deciding long ago that she didn't want to wear one. As such, I was able to see her breasts as soon as she got the gown off. My sister's bosom was bountiful, with nice and round D-cup breasts and puffy pink nipples that looked very suckable. Bonnie had a little bit of pudge around her lower body, mainly in the hip area, but it only helped to make her look even more attractive.

"So, what do you think of me? Do you think I'm sexy?", she asked, deliberately making her breasts jiggle a bit. The sight of her almost naked body only helped to stimulate me further, causing the precum to appear at the tip of my erect penis.

"Mmm...you're beautiful, Bonnie. Koji is going to be very lucky to have you as his mate", I replied, causing Bonnie to chuckle before I watched her remove the panties, showing off her vaginal folds. She then flung the panties in my general direction, landing on the bed next to me right before she started to climb onto it. I watched my sister crawl on top of me slowly, having a glimmer in those blue eyes of hers. Soon, Bonnie and I were face-to-face and nose-to-nose, with her placing a hand on one of my cheeks.

"For tonight, you're the only one I want to think about, Adrian", she softly told me before I felt her lips touch mine, kissing me for several moments, making sure to get some of her lipstick on my mouth in the process. Her kiss only helped fuel my growing sex drive, as I felt my member twitch and leak with even more precum while my sister's pussy was inches away from the tip of it. After she kissed me, Bonnie sat up in my lap and grabbed my stiff maleness, aiming the tip of it at her vaginal folds. I soon felt it touch her warmth, with Bonnie placing it just outside of her vaginal entrance. "Mmm...put your hands on my hips", she suggested.

Curiously, I did as Bonnie asked, holding both of her hips with my hands while she kept my pole aimed directly at her opening. Then, as soon as I had a hold of my sister, I watched as she slowly lowered herself down onto my length, causing the tip of it to meet with her opening briefly before pushing inside.

I gasped for a moment, then let out a long moan while I held my sister's hips, feeling her passage slowly take me inside of it. Her pussy felt warm and snug, her vaginal walls seeming to spasm around my member as she took it in, with plenty of sauce to help make the penetration easy. I felt a spurt of precum leave my tip soon after, hitting Bonnie's cervix as I watched her folds slowly engulf my length.

"Mmm...looks like someone likes his sister's pussy!", Bonnie playfully commented before taking more of me inside her. She then made her vaginal folds squeeze my length, getting me to moan with pleasure as another spurt of my precum launched upward into her reproductive tract. "Mmm...yes...I love how you feel in me, too. Your dick seems stiff and thick, it fills my insides rather nicely", she soon added with a bit of a chuckle. "Mmm...and I like the way you're spurting precum into me as well. Feels so warm and sticky...makes me eager to see what your seed will feel like in my womb when you cum", she continued before I felt her hands rest on my chest.

"Now, hold onto me tight and enjoy the ride", Bonnie soon added as I gripped her hips firmly, making sure that she would not be able to slip free from my grasp.

"Ahh...yes...ride me, Bonnie!", I called to my twin sister, growing more eager to feel her massage my throbbing maleness.

She chuckled, then started to move, going up and down at a slow pace to begin, having my member brush against the moist insides of her vaginal canal. The motion began to produce a soft squishing noise, with her juices doing their best to lubricate my length from root-to-tip.

I felt my length throb with delight as Bonnie's tight pussy massaged it, enjoying the ride as I watched her move up and down on my lap. As she did, I also watched her breasts move up and down a bit, showing that they were quite bouncy. I was tempted to reach out to fondle them, but I didn't think Bonnie would want me to move my hands from where they were, so I simply kept them put for now.

As Bonnie started to become more aroused, I felt her ride my pole a bit more aggressively, moving faster and causing the squishing noise of our union to become more noticeable. Furthermore, the temperature of her hole increased, with her passage also becoming more slippery around my length. "Mmm...yes...this feels so good! It feels like you were made for me!", she replied happily, growing more excited as I kept holding onto her hips.

"Mmm...you're a perfect fit for me, Bonnie", I told her sweetly, feeling my own arousal growing. I could feel a load of seed starting to build within my loins, my length becoming more sensitive to touch and growing a bit thicker against Bonnie's tight vaginal passage. "I can't believe we didn't do this sooner...and to think of all the time I spent getting laid at sex clubs", I thought to myself while enjoying my sister's pussy, feeling Bonnie move up and down on my shaft faster while her vaginal walls tightened around it.

I wanted to do more with my sister, so while she was bouncing on my pole, I started to hump upward, adding to the massage we both felt. "Ahh...yes...getting horny aren't we? Are you getting ready to shoot a big load in my pussy?", Bonnie replied when I humped her, both of us moving together with the rubbing of our genitals increasing.

I was tempted to inseminate Bonnie, but I still had some doubts about doing so. "Bonnie, are you sure you want it? I mean, I'm willing to give it to you, but...", I started to reply before I felt my sister's finger touch my lips, silencing me.

"Don't ask, just do it!", Bonnie replied in a playful manner. "My womb is yours to fill tonight, so don't hold anything back, OK?", she soon added.

Hearing her reply convinced me that I should go all the way with her, so I kept delivering my member into Bonnie's tight and quivering hole, soon taking the lead for the both of us. She stopped bouncing on my shaft while I humped her, sending my pole deep into her reproductive tract, massaging it vigorously. "Mmm...yes! Keep going!", Bonnie called to me as I felt her vaginal walls ripple excitedly around my length, with her drawing closer to climax.

"Ahh...Bonnie! You...you're the best sister in the world!", I told her as my climax neared, my balls churning intensely as a thick load of seed seemed about ready to spew forth into her.

"Mmm...Adrian...I love you!", Bonnie answered happily, just as I felt her insides spasm tightly around my length as she squealed in delight. A torrent of warm vaginal sauce washed through her passage, soaking my member and splashing against my crotch. It felt pleasant and gave off a fragrant aroma that tingled in my nose.

I did my best to keep going, humping Bonnie in an upward motion as I held onto her hips, feeling how slippery she had become after her climax. "Mmm...I don't know...how much longer...I...ahhh...can hold it back!", I told Bonnie as she looked at me with a smile just as I noticed two short and sharp temperature spikes occur along her vaginal passage.

"Mmm...go for it! Fill my receptive womb with your cum! Show me how much you want to make babies!", Bonnie cheerfully and playfully remarked.

I knew that there was no turning back now. It felt too good for me to stop humping my sister, I simply had to finish what we started and hope that the caps would keep my seed from meeting with her eggs.

With my climax about to hit, I took Bonnie in my arms and held her to my body, humping upward into her moist and warm pussy as I started to feel my load rush from my balls and down my length. Seconds later, I let out a long and passionate moan, feeling my sperm starting to leave my tip, splashing against Bonnie's cervix and womb.

Bonnie gushed a second time when I came inside her, sending another wave of her warm and fragrant nectar splashing against my pulsing member and crotch. Her vaginal walls tightly hugged my maleness, seeming to tug on it just a little, as if it were trying to milk as much seed from me as she could. "Mmm...yes...so hot and creamy!", Bonnie called to me happily, enjoying everything that was being pumped into her.

I started to brush my hand along my sister's back, rubbing it gently as I felt her quills tickle against my hand a little. "I can't believe that you'd actually let me do this", I replied, still shooting my load into Bonnie while she was on top of me.

She touched my cheek and smiled. "Why wouldn't I? You've always been there for me and you mean as much to me as Koji does", Bonnie told me softly as I felt her pussy tightly squeeze my pulsing length. "In fact, if you were to get together with Miyako, maybe we could let the two of you move in with us. After all, Koji still wants to spend time with his sister, just like how I want to spend time with you", Bonnie added.

"Mmm...you know what, that does sound pretty good", I replied softly before I felt my sister place a kiss on my lips, all while I kept pumping more of my seed into her receptive body. She seemed to take every drop I gave to her, making it appear as if she were trying to get pregnant from me.

"You feel so pent up, Adrian. Why don't I stay here with you for the night", Bonnie soon commented as my cream continued to spread inside her with my load still leaving the tip of my maleness.

I continued to stroke her back a little and curiously looked at my twin sister. "Are you sure about that, Bonnie?", I asked calmly, slowly feeling my climax die down.

"Mmm...why not? Wouldn't it feel a lot better if you had someone to sleep with tonight...because quite honestly I'd much rather sleep with you than sleep alone", she mentioned, just as the last bit of semen left my member and it started to soften. "Plus, Koji told me that he's spending the night with Miyako and they're probably doing the same thing that we are", she continued.

It had been a long time since I last had anyone spend the night with me, and snuggling with my twin sister sounded better than sleeping alone, especially after what we've done. "Mmm...alright...you can stay here for the night", I told Bonnie softly, just as my length slipped from her pussy, leaving behind a cream filling that oozed from her entrance.

After she felt my member leave her pussy, Bonnie moved her lips towards mine and gave me another kiss...a much deeper and longer kiss. I could hear her moan with pleasure while she kissed me, going as far as to put her tongue in my mouth. It was a bit of a surprise at first, but it felt good and I soon returned the favor by deeply kissing Bonnie and touching her cheek gently. There was no going back now, my sister and I were officially lovers, and I felt happy that Bonnie saw me in the same way that she saw her soon-to-be husband. I wasn't sure what the future would have in store for us, but if what Bonnie told me about Koji and Miyako was true, I'm sure that we would be able to spend a lot more time together like this.
