Getting into Mary?

The party was a livley one something that Wyatt never experanced before, to him it was more like theRoman Orgies he read about. He saw people sucking and fucking in every possible corner of the back yard. Wyatt watched as one man approaced Jill who in turn slapped him in the face telling him she was not on the market and that she was satisfied with her man. This made Wyatt feel good. Mary turned her back one one couple and walked away.

Wyatt approached Jill and said, "I think it's time that we help Mary out don't you?" Jill put her arms around Wyatt's neck and kissed him long and hard, Wyatt kneeded the soft flesh between her buttocks and thighs. Jill groaned softly in his ear, "God yes!, I'm so horny." With that Jill walked over to where Mary stood and with her hand on Mary's ass, she whispered in her ear. Mary smiled and walked into the house with Jill, Wyatt followed.

Mary let out a little gasp when she saw the room. There was a King Size bed with silk ropes on all four corners and other instraments of sex laying about. Before she could turn around Jim had her on the bed with her arms spread and her clothes stripped off. Jill tied her arms to each post. Jill then got Mary's legs tied spread eagle. "What are you two doing?" Mary said still struggling to get loose. Jim said, "Nothing just a little experiment Mary, we thought it might be fun to try something different." Jim then deftly stuck a vibrator into Mary's pussy. The vibrator was attached to a special piston like object. "What shall we try first?" Jim asked Jill. Mary was writhing on the bed. Jill handed him another special dildo, it too warms up when plugged in. This one had ribs on it. Jim pluged it in and then attached it to another special piston on the bed, this one was positioned under Mary's ass. Jim looked over at a very frightened Mary. "Don't worry honey, we haven't tried it out yet but we know how well it will work and I thought it would be fun to try it out on you first." Mary tried to escape the approaching dildo, she could see that it moved up and down and side to side. She heard Jim say to Jill, "It works!" The dildo just touched Mary's anus when it started to move up, down and sideways. The first dildo was moving slowly in and out of Mary's pussy.Mary let out a gasp, then Jill and Jim started to play with Mary's nipples causing her to writhe against the two warm dildos. Mary was swetting and begging, "Please don't do this."
