The only person she knew she could depend on looked back at her from the other side of the twin birthday cakes.What was Corina's secret? Abby wondered...for perhaps the millionth time. It wasn't hotness; they'd looked in mirrors more than once and agreed (objectively) they were equally well-equipped to tease boys, although the analysis was strictly academic. Both girls were far more interested in studying the attractions of Justin Bieber (maybe just a little too young) and Justin Timberlake. ?Wait a minute, said Bill, you?re forgetting something.??What?s that?? asked Sam.?The top,? said Bill.?What are you talking about? I don?t need a top.??Oh, I think you need it. It?s hardly appropriate to wear a bikinibottom only. It?s part of a set, you know; they?re supposed to gotogether. Don?t think you?re going to wear that little skirt and gotopless! Come on, put it on,? said Bill, picking the top up off the bedand handing it to Sam.Sam looked dumbly at the top for a second, then was. Saying how I drove her to college, she met Jessica, her best friend and went to class and so on and so on she went. Telling her own mother this convincing lie. I was amazed at how easily she was doing it. As she was talking I felt something touch my foot and then slide up my lower leg, on my shin. I looked to my wife to see no reaction or clue that is was her. I then looked to my daughter as she was telling the story to her sultry eyes delve deep into mine. She was slowly moving her leg up. ..... inside of me, invading my body, forcing open my tender flesh, burrowing through until it's entire length is buried and coated by the silky wetness inside. "MMMmmmm that's it..... that's a good slut ....."My whimpers and squeals get drowned out by his euphoric groans of pleasure. I feel his hands slip out from under me, the weight of his body lifting off of me. My legs being lifted and pushed back towards my face, my ass and legs being held up in the air. "MMMMMMMmmmmmm" I moan desperately.
