Filling My Brother The First Time

Part 1/2

By WaffleSquadron

"Can I see your penis?"

"What!? No! Why are you even asking me that?" I shot back.

That was not a question I expected to hear coming out of my nine year old brother's mouth. It was time for bed, and I was just about to turn off the lights, when he sprang that on me.

Cody made a pouting face and whined, "Why not? I've seen you naked before; what's the big deal?"

"The last time you saw me naked I was ten! That was two years ago."

We shared a room, but I had become self conscious since then and made it a habit to get changed out of sight from others.

"So? What difference does that make?"

I sighed in frustration. Cody could be very insistent when he wanted something, and this looked to be one of those times.

"Because I don't look the same as I did back then. Why do you want to see my penis anyway?" I said.

"I just... I just do, ok?" Cody responded.

"Ugh just tell me the real reason, or you can forget it." I spat out.

"It's... it's because I don't have one, alright? I'm a boy so I should know what a penis looks like, and you're the only one I can ask about this kind of stuff," Cody answered, his voice starting to shake.

Great now I somehow felt guilty. I always tried my best not to make Cody feel weird about being born intersex and having a vagina, but this whole situation was something I'd never dealt with before. He was a boy after all, I couldn't deny that, so what was the harm in showing him?

It was in that moment I had an epiphany. Since Cody was a boy, there was no harm in looking at him naked either. The fact that his parts were a lot more interesting to a horny canine boy was just icing on the cake.

"Can I see your spade?" I asked.

"WHAT!?" he practically yelled.

"Come on, it's only fair. Besides I've seen you naked before too."

"Kyle come on... You know I don't like people looking at my thing," he whined.

"Cody I never, ever made fun of you for that. You know I'm not going to now"

"...but why do even want to look at that. It's just weird and gross and I hate it," he said sadly.

"First off all: you're not gross. Ok? Don't say that. You're just different and that's not a bad thing. And I want to look because I don't have a pussy and I really want to see one up close."

He didn't say anything for a little while, and looked like he was considering his options. Eventually I decided to speak up, and uttered the phrase that started so many childhood explorations.

"I'll show you mine, if you show me yours."

"Fine," Cody relented.

Neither of us made a move to do any actual showing, however. Talk was one thing, but actually getting naked in front of someone is a lot more difficult when you're twelve. In the end burning adolescent curiosity won out, and I tried to move things along.

"Umm did you want to get naked first or should I?" I asked.

I didn't exactly know the correct protocol for comparing parts with another boy.

"I dunno... I don't want to go first though," Cody said.

Neither did I, but there was an obvious compromise.

"Ok how about no one goes first; we just take off stuff at the same time. That's the fairest way to do it," I offered.

"Ok... I guess that works," Cody responded quietly.

I sat up and Cody followed suit. I started to remove my top, and he mirrored my actions almost exactly. We were both wearing pajamas, so it's not like there was a lot to take off. I just grabbed my pants by the waist and pulled them off in a single move.

We were both naked in front of each other for the first time in years. It was weird and awkward, but I was starting to get really turned on by the whole thing.

"So can I see your penis now?" Cody asked.

"What? I'm already naked, go ahead and look."

"No! That's just your sheath, I want to see your penis. You gotta make it come out."

Crap. I thought I could get away with just this much, but he was right.

"Fine. But you gotta let me see your vagina then, not just the outside part," I countered.

Cody didn't say anything, he let out a "Hmmph" and nodded his head.

I took that as agreement, and started rubbing my sheath a bit. Getting hard in front of my little brother was not something I ever imagined doing, but the promise of seeing a pussy up close was overriding my better senses. It only took a few strokes before there was some pink showing from my groin; a few more and most of my shaft was hard and sticking out.

"Whoa, is that really your penis?" Cody asked.

"Of course it is, what else would it be?" I said.

"I dunno... I just never saw one before," he said, sounding a little chastised.

I felt bad. I didn't want to him to feel stupid; this was stuff a boy should know.

"Come over here and take a closer look. Sit next to me, I'll show you how it works."

Cody jumped up without any hesitation and padded over quietly to my bed. He plopped right down, and suddenly I had a naked little boy staring at my dick.

"Umm ok I guess I'll explain the parts. This little hole is where I pee from..."

"Is that where the baby-making stuff comes out too?" Cody asked, not taking his eyes away.

I wondered how he knew about that, but answered, "Uh yeah it's called sperm."

"This part is the shaft and this part," I said tugging my sheath down all the way, "is called the knot. When people make a baby it gets real big and locks them together."

"Cool... it's all, like, hard and sticky-outy. Does that hurt?" Cody asked.

"No it doesn't hurt, it kinda feels good actually. When it's hard that's called a boner, and it only happens when you're excited."

"Boner? That's a weird word. Is there really a bone in there?" Cody asked.

"Yeah, actually there is. It's called a bacu-something, and a lot of morph species have one. I don't know about humans though."

"Ok. But what did you mean excited? Do you get a boner every time you're happy? That sounds annoying," Cody said.

"No not like that kind of excited. I mean..." I said, trailing off.

This was starting to get embarrassing, but there was no point in backing out.

"You get a boner when you want to have sex. Well sometimes they just kinda happen for no reason, but it's usually cause you're thinking about sex."

"Oh... does that mean you want to have sex right now?" Cody said, asking the obvious question.

I had to laugh a little. "I always want to have sex, but I just do it by myself."

"What do you mean?"

Well crap. I kinda walked right into that one. I didn't really want to talk about masturbation with a nine year old, but hormones were already pushing me to take the problem in hand.

"Umm well a boner will eventually go away on its own, but there's a way to make it go down a lot faster. It's called jerking off. You rub up and down with your hand, and squeeze behind the knot, and it kinda tricks your body into thinking you're having sex. Then the sperm comes out, and your penis gets soft again."

It was pretty obvious what he was going to ask next, but I was prepared for it.

"Wow cool! Can I see your sperm come out? I want to see what it looks like."

This had gone way further than I ever planned, and things were starting to get a little out of control. But at the same time I really did want to jerk off. Besides my friend Pete and I had been doing it together for about a year already. Cody was a boy, so I didn't see the harm in doing it with him too.

"Ok, but you have to promise not to tell anyone about this. We could both get in big trouble," I said seriously.

"I promise, now show how to jerk out," Cody said impatiently.

"Off, not out. And ok."

I gripped down behind my knot with one hand, and started to rub up and down my shaft quickly with the other. At twelve years old my technique was still quite primitive. The whole point was to get an orgasm, so I wanted to get one as soon as possible. Doing it with my little brother watching was actually giving me a bit of a thrill. Anything new was a turn on at that age, and this was certainly naughty enough to make the whole experience a little hotter. I was jerking off for about a minute when Cody spoke up.

"Umm Kyle... Can... nevermind," he said.

"What? You can ask, it's fine," I said.

"Umm... Can I try doing that for you?" he asked shyly.

My hand stopped moving. I really hadn't expected that question.

"Ohh. I dunno... That's kinda personal," I responded.

"It's just that I'm a boy and I want to know what a penis feels like."

He was getting a lot of mileage out of that particular argument, and I was going to fall for it again.

"Ok here, just grip it in your fist and slide your hand up and down a bit," I offered.

He latched on immediately, and started to rub me with a few slow and cautious strokes.

"Whoa it's hot! And it's kinda slippery too. This feels cool, it's really hard. Are these your balls?" he asked, reaching his other hand down and squeezing my scrotum.

"WHOA stop! You're gonna crush them. Yeah they're called testicles, and they are very sensitive," I almost yelled.

"Sorry," was the only response he gave.

He kept stroking me for a few more minutes. He was not an expert by any means. In fact he was downright bad at jerking off. But the feel of someone else touching my dick was quickly bringing me to the edge. His paws were small and warm, and I never knew what they were going to do next. When he finally gave my knot a nice squeeze I reached my limit.

"Cody I'm getting close, maybe I should take over."

"Is the sperm gonna come out? I want to do it!" he said, speeding up.

I was past the point of caring. My hands just gripped onto the bed for balance, and my legs spread wider in anticipation. My orgasm was coming on strong, and I felt my cock swell up to its maximum size.

"Fuck here it comes," I squeaked out.

My eyes snapped shut and the waves of pleasure rolled over my body. I could feel my dick throbbing in my little brother's grip and the unmistakable sensation of semen pumping out. I savored the feelings for a moment before opening my eyes again. I expected to see a grossed out little brother, but instead he just had a look on intense curiosity.

"Is this all your sperm?" He asked, scooping up my meager load and rubbing it between his finger tips.

"Yeah that's it."

"I thought there was going to be more, though. And isn't it supposed to shoot out really far? Yours just kinda spit a little." he asked.

Now I had some questions that needed answering. For a boy that knew nothing about this a few minutes ago, he sure had some rather specific expectations.

"Why did you think that? I thought you had no idea how any of this stuff worked," I asked accusatorily.

"Uhhhhhhhhhh..." Cody said with a look that meant 'caught'.

"Dude just tell me. I jerked off in front of you; I'm not going to tell mom if you were looking at porn."

"No! It's not porn. I just read some things. There are all these stories about sex stuff and I was curious," he answered.

"Cody it's still porn even if there aren't any pictures. And don't believe all that stuff, people can just write anything it doesn't mean any of it's true."

"Oh... Umm so did you want to look at me now?" he asked.

I had just cum, but was still incredibly horny. Sometimes I had to do it two or three times in a row to settle down, and the promise of seeing a real pussy meant I was not about to go soft.

"Yeah!" I said enthusiastically.

Cody spread his legs wide open, and I leaned over to get a view. To be perfectly honest, it didn't really look like much. I was sitting next to him and looking down between his legs. From that angle it just looked like a darker bit of skin. I tried moving my head around to get a better look, but it didn't change much. I had an idea, but when I looked up and Cody he seemed very uncomfortable. I knew this was asking a lot from him, so I wanted to get permission.

"Cody, can I move down to get a closer look?"

"Yeah. Just... just make it quick," he said, not looking at me.

I slid off the bed, and kneeled between his legs. From this vantage I could see a lot more. His spade was darker than the surrounding fur, while the lips looked kind of puffy and stuck out from his body. They kind of made a triangle shape, coming to a point at the top. And there was kind of an upside down Y in the center where they touched. I didn't really know what to expect, but I was fascinated by what I found.

"Can I see inside now?"

Cody didn't say anything, but he brought his hands down and with two fingers pulled the lips apart. The first thing I noticed was the wetness. As soon as his spade was open there was the unmistakable shine of moisture. The second thing was the smell. I had no idea what it was then, but that was the first time I ever took in the scent of a canine pussy. It was light and sweet, and seemed to take over my brain. As his lips opened fully I was surprised by how pink they were inside. It was so bright I couldn't look away.

"Wow that's so cool," I said almost reverently.

"Can you show me what parts are what?" I asked.

"Umm sure ok. That hole is where I pee from," he said pointing to the large opening.

"Is that where a boy puts his penis inside?" I asked.

"Umm I dunno. Maybe? This part near the top just kinda tickles really weird if I touch it," he continued.

"Oh is that your clitoris?" I asked.

"My clitor-what? I don't know. I told you I hate this thing, I don't like looking at it a lot," he said with a huff.

I realized that there might be something I could do to make him like his pussy a bit more.

"The clitoris is kind of like the penis. I learned that if you rub it, it feels super good. That's how girls jerk off and have orgasms."

"I'M NOT A GIRL!" he shot back instantly, snapping his legs shut in the process.

"Sorry! I didn't mean it like that," I said in apology. I should have known that was a dumb thing to say, but sometimes the words just came out stupid.

Cody still looked pissed but asked, "What was that word you said? What's an orkasm?"

"An orgasm is like the best feeling in the entire world. Before, when I squirted out sperm, I had one. It was like all the good feelings ever were coming out of my dick. It's hard to explain, but gir-I mean people with vaginas-can have them too," I said, almost ruining things again.

Cody let my slip-up go without comment. What I had just told him was far too interesting to pass up.

"Ok. But when I touch that clitoral thing it just feels tickly, not super good."

"Well, I could try touching you there..." I said leaving the offer hanging in the air.

Cody didn't say anything in response, but I could see the gears turning in his head.

"Promise to stop if I tell you to?"

"Of course," I answered.

"Ok I guess you can touch it a little bit," Cody said, opening his legs again.

I didn't waste any time, and put my face right back down near his pussy. I could feel the heat radiating off of him against my muzzle. I moved my hands up against his thighs, and carefully used my thumbs to open the lips of his spade. I was surprised by just how soft and squishy they were. The insides looked just like before, but now I had an extra close up view.

The entrance to his vagina looked so inviting. I ran my finger along his pussy, feeling the slippery subtle texture inside those lips. I wanted nothing more than to shove my cock inside, as deep as it would go, but I couldn't bear the thought of hurting my little brother. I touched a little higher, looking for his clitoris. I found it inside a seperate little pocket; the texture was slightly rougher, but the second my finger came in contact Cody let out a little hiss.

"Did that hurt?" I asked, concerned.

"No, it didn't hurt. It just felt... I dunno... tingly," Cody replied.

I just smiled, "Good, that what's supposed to happen. Just sit back and relax."

I gathered more of the wetness around his pussy, and went back to rubbing his clit. Cody's eyes shot wide open, and he hissed even louder than before. This time I didn't let up, making tiny circles around his button and rubbing it even more. I could feel it get slightly harder under my pawpad, and Cody started to moan. His spade looked like it was getting even wetter than before, and an idea suddenly popped into my head.

"Can I put my finger inside? I'll make it feel even better that way."

"Noooooo that's too big. It'll hurt," he said between moans.

"How about just my pinky?"

"...ok but only a little bit"

I didn't waste anytime, and ran my little finger through his folds to get it lubed up. I placed it right up against his entrance, and pushed in slowly. Feeling the tight squishy walls of his pussy wrap around my finger was the sexiest thing I had ever experienced in my twelve years of life. I nearly came again just from that, and Cody's head snapped back in ecstasy. I started to push in and out while rubbing his clit at the same time.

He let out a little whine and said, "Kyle, I feel weird!"

"It's ok, just let it happen."

He wasn't moaning anymore, but was breathing much louder and faster than before. It only took about thirty more seconds of finger fucking before he took one last big gasp of air and grabbed onto my hands to stop them. Cody's head popped back up, and he stared right at me; his face looked scared at the powerful new feelings racing through his body. I felt the walls of his pussy clamp down on my finger, hard, before starting a set rhythmic contractions around it. The breath he held in came out in one long groan as the preteen boy experienced the first orgasm of his life. His hips were giving little humps against my paws, and I felt the fur on them becoming soaked with his wetness. Ten seconds after it started Cody's orgasm died down, and the young boy collapsed backwards onto my bed.

"That was an orgasm," I said.

He couldn't even speak, his breath still coming in gasps. Eventually he regained enough composure to lift his head and say, "That was... so... oh man... I had no idea anything could feel that good."

I was trying to think of some clever response when we heard the most terrifying noise imaginable.

*KNOCK* *KNOCK* *KNOCK*

I felt my heart freeze in my chest, and the strength drain from my limbs. I looked at Cody and he had the same look of horror across his muzzle. There was nothing we could do but wait for the inevitable disaster.

"Boys. Lights out was twenty minutes ago. Get to bed right now. You two are going to be in big trouble if I have to come back," our mom said from the other side of the door.

We both shared a moment of relief, before racing to get off the bed and back into our pajamas. I decided to forgo pants for the time being, and instead raced bottomless to click the bedroom light off. I slid underneath the covers, pajama bottoms in hand, and tried my hardest not to make a sound. I don't know how long it was before my heart stopped racing, but it must have been a few minutes later when a quiet voice spoke from across the room.

"Kyle... thanks for showing me that. Can we... umm... do it again sometime?"

I couldn't help but smile in the dark. I brought my still damp paw up to my nose, and gave it a sniff. The scent of his pussy filled my nostrils once again, and my cock instantly became stiff.

"Cody I want to do that every chance we get."
