I grabbed her bottom spreading her cheeks and she gave a satisfied squeal. I moved my hand down rubbing her clit and moved some of the moisture up to ...er back door. I then got closer and rubbed the sensitive underside of my dick on her puckered area. She was at this point moaning and abruptly reached around as she moved the angle down a little and with her fingers pushed me into her ass.I was expecting this activity to go slow and gradual but not today. She reached with her hand toward my hip. Andrew was a scientist. At the extremely young age of 18 he had concocted a formula to make himself invisible. He had had lots of fun with the elixir. He had gone into many shops and stores and stolen more than enough money from cash registers to live very comfortably. He also liked jewelry stores. When the cases were open he would go right up beside the clerk and snag a diamond ring or two. He would always have fun with the sales girl. He would blow on their neck or pinch their ass. . As quick as he went in quicker came his way out asking why were my bra and panties on a towel in there. I told him that we left the bag in the trunk and that I wasn’t going to put in dirty underwear on in the morning. Besides I left room for his too. He said that’s right, we don’t have any PJ’s. I confirmed I always sleep naked anyways. His last words before the shower was to ask what was he to use to dry off now that his towel is under my panties. I told him to use the hand towel hanging on. I did the same. After sometime, he changed the video and put a lesbian one. I lost interest and started stealing glimpses at his cock with pre-cum oozing out. For some reason I wanted to taste it. Now i wasn't jacking off to the video, now it was to his huge strong cock. I think he caught me looking a few times."Hey Jake, have you ever sucked cock" he asked me, a hunger in his eyes"No, never" I said"Well, once I was playing to save the world with a friend like you and I used to. And throughout.
