The top lad grunted and groaned as he grind his midsection into the bottom lad. Panting heavily the top lad extracted his still erect penis from the ...bottom lads anus. The lads head dropped down a little below the log. Another well hung lad knelt between the quivering thighs of the bottom lad. I could see the enormous tool that the lad was welding and almost cried out in disbelieve as he poised the massive head at the butt crack of the young lad. On his knees, the top lad maneuvered his body up. He invite me in. The cabin was small probably 20 by 20. A third which was where the door was as you entered was the kitchen with a bathroom at the back. The other part of the cabin was his bedroom with a queen bed and a closet at the end of the bed with sliding glass doors.The one on the right was open and a large flat screen TV was on there providing light for the room. I started to undress and placing my clothes on the dresser by the door. He got some lotion out of a drawer and laid down. ’I’d never talked quite so explicitly with Mom about Mr. B, but I figured she should know what she was getting involved with. So I told her to have fun with him and to let him know I was ‘cool with it’. She asked me then if I could get her some estrogen cream and some lube because she wasn’t as young as she wished she was. I had both of those in my kit, so I fixed her up.On the next 3rd night I asked Mr. B if he was in the mood to give me some quiet time with the kids. He got a gleam in his eye. She gave great head, and I was so turned on being watched. I pulled her head down as far as it could go and she gagged, looking up at me I smiled. The chat was going wild, I didn't read what they were typing because I was having to much pleasure, but I saw the lines scrolling like a teleprompter. She looked up at me and I pulled her up to kiss her deeply, then told her to get into doggy position. I gave her ass a nice spank and a bite, then I touched her drenched sweet pussy. She was betting me.
