We also decided to inform one of our watchman that we will go home but in fact stay back and execute our plan. As decided I and Sam went back to the p...rking area and punctured her tyres. But for the safe side we removed her scooty from the stand and put it down in the water. As water level was high the scooty was hidden inside the water. Roy informed watchman about us leaving.Then we all go inside the school campus from the backside. And went to the third floor. We saw mam rushing outside in. Mary was bracing her arms against the wall, now, pushing back against my thrusts. Mary's tongue slipped into my mouth, playing with my tongue. My balls were tightening as Mary's cunt was bringing me closer and closer to cumming with every plunge into her velvety tunnel."You feel so amazing," I moaned. "Are you close?" Oh, yes, Mark!" Mary gasped. "Uhm, I'm getting closer. Ohh, just keep sliding in and out of me, hun."I nibbled on her ear as I thrust harder into her, enjoying her gasps and moans. Helen had begun making the little clipped whines she was prone to utter as her orgasm approached. When the last one trailed off into a long sigh, I knew she had come.Raver's testicles did that same melting action up into his groin that I had noticed before. He suddenly slowed his pumping and collapsed on her, convulsing spasmodically.As my own climax arrived, I had to place a palm tightly over my mouth to avoid giving myself away. Having worked so hard to get it, the jolt left me utterly. My aunt was wearing this tight shirt and very small shorts. Without staring too much, I could see camel toe was showing. Sue gave me a big hug and she welcomed me inside. I thought my aunt would explain why she needed to see me. She never did say why. Instead she offered me a beer and we sat down on the couch to talk.Sue wanted to know all about my life. What was my major at school, did I have a girlfriend, anything about what I was doing, Sue needed to know. Sue told me very little about her.
