[Drifter79]

I was standing outside the bathroom door, waiting for my sister to get out of the bathroom. I really had to pee so I pounded on the door and yelled, "Come on Sabrina! Hurry up, or I'm going to pee in my pants!"

I had to go so bad my cock was hard. I hated trying to pee when it was like this. Trying to bend it down to pee hurt. I was getting mad and I was biting my lip trying not to pee. Finally the door snapped open. Sabrina with standing in the doorway with a towel wrapped around her wet hair, and another one wrapped around her body. "Don't rush me, Shit!"

Standing there hopping up and down, with my hand holding my cock trying not to pee. "Out of the way!" I said, as I pushed by her into the bathroom.

"Hurry up so I can dry my hair," Sabrina snarled back at me as I slammed the door.

As I stood peeing, I thought how pretty my sister really was. "No, she's a girl, and my yucky sister." But when I finished peeing, my cock stayed hard in my hand. "Why?"

I thought of Sabrina standing in her towel drifted back into my mind. I rubbed my balls, and squeezed my cock, trying to get it back to (what I thought was) normal.

As I squeezed, a weird feeling went through my body. Well not weird bad, but weird good. So instead of squeezing I moved my hand up and down my little shaft. Thoughts of my sister standing in the hall dripping wet, went through my mind again. Then... Sticky stuff squirted out of the head of my cock. "WOW!" The feeling almost knocked me off my feet. I stroked again and more shot out, "Double WOW!" I could hardy breathe. I had to do it again. Then...

"Come on, Shit. I need to dry my hair!"

"O-oh okay, I'm almost done," I replied, trying to sound normal. But I know it came out making me sound like I was out of breath. I wiped the white stuff off my hand, then opened the door. "Here you go YOUR HIGHNESS."

"Ha Ha, very funny," Sabrina said, as she went by me back into the bathroom.

When she pushed by me, her tits brushed up against my arm. For some reason it felt good. Sabrina had nice boobs too. The older guys were always talking about getting their hands on her BIG HOOTERS. That's what they called them. I always thought they make her look stupid. But tonight they made her look different. I guess you could say sexy.

I looked back at the door and it was open just a crack. I could see her in the mirror. Sabrina was standing running her fingers through her wet hair. Sabrina's hair was actually pretty tonight, long, naturally curly, and blonde. She looked in the mirror and tried to look sexy. She smiled and puckered up her lips. Then she reached down and squeezed her boobs through the towel. She licked her lips, then dropped the towel on the floor. She was now naked! She cupped her breasts lifting then up and let go, they bounced and jiggled. She looked in the mirror and stared at her hands as she squeezed her tits, and pulled on her nipples.

That was enough for me. My cock got hard again, and I didn't even have to pee! As Sabrina played with her nipples, I rubbed my cock. I don't know how big my sister's tits were, but the boys at school always said that they must be 37-D at least. They said they probably would sag without a bra, but they didn't. She closed her eyes and kept pulling and twisting her nipples. As she played with them, they even got hard!

I never could figure out why men thought women were anything to look at. But now I couldn't imagine anything that I'd rather look at more than Sabrina, my own sister playing with her boobs. The feeling started swelling up in me again. I looked down at my cock. There was stuff running out of the end, making my hand slide easily up and down the shaft of my cock. I looked back to see what Sabrina was doing. What I saw made me squirt sticky stuff all over the bathroom door. She had one of her breasts in both hands, and had bent it up to her mouth. She ran her tongue around her big hard nipple, then locked her lips around it and started sucking.

I squirted again, causing me to moan out loud. Sabrina's head jerked around and looked at the door. I ran to my room and slammed the door, hoping she didn't see me. After thirty minutes, when she didn't come pounding on the door, I knew she didn't see me or she'd be screaming her head off. I closed my eyes, and quickly fell asleep. I dreamed all night about my sister sucking on her huge tits. When I woke up there was sticky stuff all over my stomach.
