She slammed me down onto the sofa, and without warning, started rubbing my jeans. "I saw you looking at me, Robert. You aren't very subtle." She state.... "Sorry, but who wouldn't stare at you dressed like that!?" "Shut up and unbuckle your belt, and pull down your drawers." My sister easily overpowered me, as I was shocked by what was happening. I did as she said, but stopped at my boxers. "Too scared?" She said, "I'll do it then, pussy." So here I was, my 7 incher sitting out in our small. Pammy stopped and asked where I wanted to cum. As much as I wanted to shoot it down her throat so she could swallow it, I've always had a thing about getting my cum on girl's tits. I told Pammy that I wanted to shoot it on her chest. She took off her bra and revealed the beautiful boobs I've always fantasized about. There was no holding back now.I told her I was ready to cum. Pammy pulled my dick out of her mouth and aimed it right between her tits. She was stroking it hard and fast and that's. Was there a dark spot in my shorts right on my pussy. I wished I were shaved so I could have a nice cameltoe. These shorts were that tight. They rode into my butt-crack. I didn’t adjust them. I just pretended to work.He was right on us. I could feel his eyes on our butts. He had to be lusting after us. I whimpered, wanting to masturbate right now. I felt the lawnmower behind us. The power of it. The scent of gasoline and cut grass washed over me.I shuddered, wiggling my rump.Then Daddy turned. I was pretty sure she could see my hard on when I got up to leave because I was hard. She was very pleasant and nice to talk with and up close her beauty made me more interested. I decided I would go home and explore the creek from the back of the property so I parked and walked in from that direction. The area we lived in was quite hilly and the stream bed was bedrock which made it nicer to explore. Of course I was naked as I walked thinking about Kathy and how I saw her being licked by.
