Dad came back from his swim and asks; what you girls laughing so much at. Mom said I’ll tell you later honey. We all were sitting on the blanket and...Dad was serious looking at us and then at Mom, he final said you know you girl are so lucky to have your Mom as your Mom you will have beautiful body like hers and just a beautiful as well, Mom reach over and kissed Dad with here wet tongue kiss and said why thank you honey. Ten we looked at Mom real closely, of course then Mom spreads her legs so. My stockings were run andthe door was open for anyone who walked by to see. My cock was out andhard and I wanted more so badly it almost hurt.I shakily closed the door and tried to collect myself. I heard the doornext door open and shut and knew there was another guy in there. I lookedthrough the hole in the wall but it was pitch black. He hadn't put anycoins in the slot yet. He was waiting for something but I had no idea ofwhat. I stuck my tongue through the opening and wagged it and then. Danny got up with middle fingers for both Trent and me and followed me to the house.In the kitchen I whispered to Danny, “is he gay or what? Trying to hold back my laughter.“Actually dude, Trent is always hooking up with pretty hot chicks. He’s just really not into Tanlines., Don’t worry he’s not gonna try to fuck you “we both laughed grab beers and headed back outside.After a few hours of hanging out, drinking beers and smoking Trent’s mom’s pot, I got use to the Gstring and even managed to. Alan opened the door and as we entered he closed the door and locked it from the inside and pulled down the "test in progress curtain". Alan pushed me over to the far end of the class room, by the bank of ceiling high windows. He spoke in a quiet sure tone 'we're on the fourth floor and class is in session. No one is going to disturb us for at least forty minutes when classes end'. I wasn't scared or afraid but I was very well aware that Alan was going to do what he wanted even if I did not.
