We went away on a family holiday and my sister and I had to share a hotel room. She couldn't keep her horniness to herself and didn't seem to mind that I was in the same room. What bothers me most is that her cock is bigger than mine...
My mom and I watch TV together every Friday night. Because she sits on the other sofa, she thinks I can't see her staring at me. My favourite thing is to watch her cock twitch from the corner of my eye while she plays with herself.
After my step-mom and dad have sex and he falls asleep, she sneaks into my room for some REAL fun. I feel bad for him, but its not my fault my cock is the only thing that gets her hard.
