I did something pretty bad the other day. I raped my ten year old sister.

It happened like this: I went up to her room to ask her something, I forget what now. I didn't realize she had just gotten out of the shower, as I didn't hear it, being downstairs. When I opened her door, I found her strutting around her room naked, with her hair wet. I should've ducked out, embarrassed, but for some reason, I felt compelled to stare at her skinny little ten year old body; her flat chest, tiny ass, hairless, unspoiled pussy, and I felt my cock swell up to full erection.

"____, get out!" she said, covering herself, on noticing me.

I don't know what came over me, but I walked over, grabbed her by the arms, and threw her onto the bed, then I immediately whipped down my pants.

"____, what are you doing??" She then saw what I was doing, and saw my big, erect cock. "____, no!"

Ignoring her pleas, I pushed my cock into her. Actually, her being so young, I had to work it a bit to get it in far enough to properly fuck her, but when I did, it felt so good. My little sister screamed as I fucked her, probably partly from pleasure, but mostly from pain, which to be honest made it even hotter.

Needless to say, it didn't take long before I felt I was gonna cum, so I pulled out, and shot a huge load all over her, her pussy, her stomach, her chest, her neck, even on her face.

My little sister was full-on sobbing as I leaned over and kissed her, then pulled my pants up and left. She hasn't told Mom and Dad yet, and I don't know if it's out of fear, or if part of her secretly enjoyed it, but I do know I can't wait till the next time we have the house to ourselves.
