My bitch of a sister is bitching at me while I'm trying to use the bathroom. I don't care if she has to get ready for work, I'm in here. I decide to get her back and flush the toilet on her while she is in the shower, but when I see her naked, I come up with a better idea. When she returns to her room I giver her the gift of my cock. She doesn't appreciate my offer so I have to be a little rough to convince her. She even gets into it after a while and climbs on top to ride me. I have 1 more present for her though as I blow my load deep inside her, it's not my problem after all. That'll teach her!
