I really started to get excited and before I knew it I was rubbing my hand over my pussy. I unbuttoned my jeans and reached inside my panties, I could...feel my pussy was already wet. My dad moved up my mom and began kissing her mouth, while she was stroking his cock. The next bit surprised my most.. I began to wish that I was the one stroking my dads cock and kissing him. The truth be told I was no longer a virgin, I had only done it with one guy and although it wasn't that great it lead me to. I like to play a game I call Mystery night. On this night I tie my wife blindfolded to the bed and then I have someone come in and fuck her. She never knows who it is, this is way she is being fooled; never knowing who is fucking her and the one fucking her is fooled because he thinks that she thinks it's me.On this night I had decided to let my Dad fuck her. He is in his mid 70's and kept telling me how he hasn't had sex in 6 years. One day I explained to him that Ellen and I play this game. RyRy came in, sat down next to me, and rested her hand on my back. Normally, Ry would wait until I talked. But this time she didn't even wait, and just started talking. She said "I'm sorry billy, I got scared. I didn't know what touched me there. I felt your hands on my back, and just got spooked." I couldn't talk. I could barely think. But Ry always knew exactly what to say to ease my mind. I was still mortified. RyRy said "Come on, and relax" and wrapped her arms around me. We laid back on. ..in his mind.Still what were the barriers to taking our own daughters, right here and now, probably nothing to stop us guys swapping and enjoying the ultimate forbidden fruit, but there was temptation enough for both of us middle aged guys; each other’s daughter ready for the arse pounding of their life.Well hell the two little bi-bitches deserved it. Wanted it. Needed it. Just as much as Tom and I.Oh sweet heaven on earth, did Amelia have a tight arse. Her arse gave everything to my cock.
