Those floors had soaked up lots of pussy and prick cum over the years. I kept feeding her hard cock, and she kept gagging and crying. But she always w...nted it, and begged for more if I stopped. I was not stopping. No, I was face fucking her now. Pulling completely out, asking if she wanted it, and then ramming it back as she pleaded for me to continue. "That's it. Yes, that's it. You want it. You wanted this. You're my little slut. Oh, fuck," I moaned, using my pet. She was making gagging. "See! That was a laugh!" said Emily giggling, as we caught up with my cousin."Yeah, well its your turn now!" Josie replied "So I dare you to flash your tits at the next one!" At the next what?" asked Emily"Car!" replied my cousin "I dare you to flash the next car!" Fine! I will!" Emily replied back firmly.Then she walked over to the edge of the path, glanced up and down the road, and as the next car approached, she grabbed hold of the bottom of her little pink t-shirt, and swiftly pulled it. ” We kissed with tongue in a five-minute passionate kiss when the outside lights flashed.Mary looked and said, “Really they think were kids.?”Brent said, “Well lets go face the music I doubt they will be pleased with our timing.” We walked in and to our shock both sets of parents were there. In unison they said, “Happy engagement night now stand there for pictures.”After the pictures a cake was brought out saying happy engagement Mary and Brent.We talked and Dad said, “We all wished we would. ” “That was my sister,” I prevaricated. “She drove all day from out of state to see me. She was really tired and didn’t want to drive at night. So, I let her stay.” Lowering her eyeglasses down the crook of her nose, the woman looked up at me and said, “She was seen on top of you, in the nude.” “… yeah… well, she was really tired.” “Are you saying that the girl your RA saw on top of you was your sister?” I tightly clenched my lips.
