Allison again took this game one step farther than me. She arched her back and hissed my name as her body shook in the throws of her teenage orgasm. �...�Ooooooooohhhhhhhhh yessssssssssss Robbbbbbbb!’ my s****r moaned out softly so only I could hear. I watched as my sexy s****r’s body reacted to her intense orgasm. She repeatedly clamped her legs together which pressed her hands against her excited clit. Her sexy little butt was lifting off the bed at the same time. Her head to one side as her. Ron was in the middle with a girl on each side. And it looked like they were all asleep. But I knew they had been fucking because the room smelled like sex.I was tired and slowly crawled into the little cot. I knew I had to shut the closet doors so they couldn't see me if they should wake up. I don't know why they don't want to see me at night. Any time they are up, I am totally exposed. But I closed the door and put my poor used body on the cot. It wasn't long and I was sound asleep.I slept. . “ohhhhhhh that’s so nice, we are just a perfect fit . . . that’s it keep doing what you are doing, push it in and out make it feel good. . . yes, yes, that’s it you are doing good” Clearly Aunt Jen was feeling similar feelings to me.The exquisite feelings seemed to intensify with every in and out movement. The tightness, the heat and slipperiness of her vagina increasing the wonderful sensations in my penis with every thrust. I was now relaxing a little and letting my feelings and nature take. ..”I smiled and helped him out of the car. I said, “Doug, I honestly don’t mind. I told you, I prefer that you have that reaction than any of the other possible reactions I can imagine. I don’t want you going crazy with jealousy or getting furious and doing something violent and stupid. And I don’t want to look in your face and see that I disgust you. If the worst thing you do until we find a way out of this is have a hard on I’ll be perfectly happy.”He looked into my eyes as if trying to.
