I went home early due to the film I wanted to watch was cancelled. Inside the house I heard moaning and groaning. Walking upstairs I noticed my older sister of 11 months on her bed with the boy Bruce fucking her pussy. I did not like him and he is a school bully, but he won’t touch me. I have knocked him out twice in school.

I stepped into the room and said “Well sis I see you could be caught again with pencil dick, You could at least closed the door.”

I left the door open and went to turn around when Bruce said “Close the fucking door or else?”

Looking at him I asked “Yea, where are your tiny dick friends now. You really want to try it again?”
He stood up and I laughed. I could not help it. His dick was just under five inches, hard, and looked like a pencil, really small. “Sis does that give you any pleasure or is he forcing you?”
The look on my sister face confirmed my worst fear. Sis replied “I was told if I did not do it he would bash you up again!”
Stepping into the room I gave Bruce an under cut that knocked him out on the floor. I grabbed my sister’s phone and took a picture of the naked Bruce with a hard cock. I quickly sent it out to her girlfriends with the message ‘Bruce shows me his hard pencil dick, don’t be bullied by the tiny prick.’
