He wasted no time. He didn't seem to have the sense of show that I possessed, but he more than made up for it with his eagerness.

First came the shirt. Next, his belt and jeans. Finally, his boxer shorts came off in a whirl of acrobatic movement.

Lord. I had forgotten just how big my brother was.

His cock was fully erect, pointing towards me like some sort of weapon. I could see much more clearly in the dorm room's dim lights than I had been able to in the closet before, and I took a moment to admire his dick.

There was no other way to describe it: it was beautiful. Smooth and firm, ending in a soft, engorged head. He seemed proud of it. He was right to be so.

I took my brother's cock in my hand; he moaned softly when he felt my warm flesh against his.

I wrapped my fingers around the shaft and slowly slid down to the base. From the last time, I knew he liked it when I grazed the sensitive underside of the shaft.

"Fuck, Ally," he moaned.

"That's the idea," I said with a wink. And then, without warning, I took him into my mouth.

Kyle moaned. Our eyes met as I slowly slid my lips down his shaft and I couldn't help but smile around it.

As I allowed him to slide down my throat, I worked my tongue over whatever flesh I could. It wasn't easy with my mouth so full, but I managed.

"God, sis," he groaned. Something about hearing him call me 'sis' while his cock was in my mouth spurred me on. I could feel my own arousal in the pit of my stomach.

I ran my hand down the inside of my panties. Soaking wet.

I would have responded. Told him just how much I love the taste of my brother's cock. How much I wanted to feel his cum spurt against the back of my throat and slide down into my belly.

But to do so, I would have had to pull away and take him out of my mouth. In that moment, pulling away entirely was the last thing I wanted to do.

I only wanted to pull away a little bit, until just the head was left in my warm, moist mouth.

I could feel his hand run through my hair, holding the back of my head loosely. I didn't need any encouragement, but he guided the motion of my head all the same.

Down again, taking him deep into my mouth as deep as I could. I couldn't fit all of him, but I tried to push further each time. At least that gave me part of his shaft to stroke with my hand again.

He seemed to like that.

"God, Ally. Fuck, sis," he repeated over and over again.

I could taste his sweet precum on my tongue and feel his body tense. He was close. That was probably why he groaned when I abruptly stopped.

His cock twitched; a small bead of precum leaked from the tip. He must have been right on the edge. Good.

I leaned back against the arm of the couch, spreading my legs and smiling. "Your turn."

The poor boy practically dove between my legs. He licked the inside of my thighs, running his tongue along my sensitive flesh until he reached the barrier of my panties.

He pulled the fabric to the side, seeing my pussy up close for the first time.

"You're shaved," he noted. "I always thought you were. I just couldn't tell for sure last time, not from the closet."

Always thought. Maybe he didn't realize what he said- not surprising, being that he was still on the edge of release- but it was very clear that he thought about my body as much as I thought about his.

I leaned my head back and moaned as he started to lick my pussy lips. It was his turn to be in control.

He ran his tongue along my slit, savoring my juices. When he reached my clitoris, I moaned again. Louder this time. Unexpectedly loud.

Thankfully, that didn't slow Kyle down; he alternated between sliding his tongue along my pussy lips and using it to gently circle my clit.

That was enough to give me the first hint of a climax. It started building in my stomach and spread to the depths of my pussy.

I was suddenly very aware of how empty I was- how my hole needed to be filled right away.

"Kyle," I moaned.

It was all I could manage. He looked into my eyes and pushed his tongue deep into me. "Kyle," I moaned again. I wanted to tell him how good he was making me feel.

How I've never felt so desperate for a cock before. How much I wanted my step brother's cum.

Something in his expression told me that he knew that already.

We were in perfect sync. That wasn't particularly surprising, seeing as how we grew up together, but it made him the perfect sexual partner. No awkward fumbling or distracting questions. He just knew me.

When he hooked his fingers into the waistband of my panties and pulled, I lifted my ass off the couch at the same time. Perfect synchronicity.

He shifted his body, aligning our hips. I wrapped by arms around his neck; he aligned the tip of his cock to my soaking wet hole. Then, for the second time, he was inside me.

It was just the head at first. I could feel it push past my lips. My body held him in place as he pushed in deeper.

"Oh, god," I moaned. I didn't want to move, so I just relaxed my body and allowed him to continue. "Please, Kyle. Fuck me," I begged. I wanted him. I wanted him to use me completely. He, it seemed clear, was happy to oblige.

I could feel every inch of him as he slid into me. He was big, but he seemed to know just how to fill me without turning my pleasure into too much pain.

He pushed inside, waited for my pussy to relax around him, then slid in deeper. Slow. Steady. Perfect. Just like before. Finally, he had filled me completely.

"I've never been so full," I swooned. I remembered thinking the same thing the last time my brother was inside me. Both times were true.

"Your pussy... you feel amazing," Kyle groaned in between thrusts.

I didn't reply. I couldn't even if I wanted to. I could only focus on the sensations building deep inside of my body. His thick cock was hitting parts of me that had never before been reached. It felt amazing.

I started bringing my hips upward to meet his downward thrusts. I could feel his balls hitting against my ass with each wild thrust, and the combination of different sensations was nearly overwhelming.

Words started streaming out of my mouth, but I had no idea what I was actually saying.

"Fuck me, Kyle. Fuck your sister's cunt!" I don't think I'd ever used that word before in my life, but something about the situation seemed to warrant it. Everything we were doing felt so exciting and new.

I wrapped my legs around his ass, pulling him closer to me as my climax started to build. More words. "Fuck me. Fuck me! Fuck me!"

My head was spinning. My body shaking. Somewhere, deep inside me, a volcano was starting to erupt. I could hear a voice- I was certain it was my own- moaning commands and encouragement. Faster, it said. Harder, it begged. Don't stop, it pleaded.

Kyle's moans joined my own. I could feel his body tense. His thrusts became deeper and more wild. That's when I heard my voice say something I never thought it would.

"Cum inside me," I begged. "Fill your sister's pussy!"

The last syllable was extended before turning into an unintelligible moan. I was cumming. So was he. My brother, who I loved with all my heart, was filling me with his cum.

And then, the world simply shut off.
