It was a Valentine's Day party. Most of the women at the party were dressed in red see-through outfits. Mary started off wearing my shirt, a bra, her sheer black panties, and socks again. After just a few minutes of wandering around Mary decided to take off the bra.
The dancing was slow and touchy-feely again. Mary did a lot of kissing, and got her tits felt up a lot on the dance floor. I think the guys felt it was just natural to feel up her tits since she wasn't wearing a bra.
I danced with several women, and did enjoy their benefits. At one point when I mentioned Mary got the lion's share of attention she asked if I was keeping score. I admit I probably was, even if I didn't really mean to.
After a couple hours of dancing, or foreplay on the dance floor, Mary was led off down the hall by the guy who owned the home. We had met him at the first party we went to, and he and his wife and given us a tour of his home when we got there that day. Mary seemed eager to follow him. We had not set any rules, so I couldn't expect anything. After I thought about it I would have preferred same room swapping, though.
A few songs later a beautiful lithe brunette in a see-through jumper danced with me. As I massaged her nipples she suggested we go somewhere and get better acquainted. Getting her naked on the huge couch was a matter of slipping her see-through barely there jumper off. She undressed me, which was a novelty for me since Mary never undresses me.
I was already hard but this beauty gave me a long slow blow job anyway, while she rubbed her wet pussy on my shin. She had one foot on the floor, off the edge of the couch, while she sucked on me. As she slid up my body to sit on my hard-on she kept one foot on the floor, and lowered herself onto me. She pumped herself up and down rhythmically, sitting up, while I massaged her breasts. She reached between us and massaged her clitoris. She was leaning down into my hands, moaning softly, while she pumped herself up and down faster and faster.
She stuttered, jerked some, opened her eyes, and put her hand on my hands to stop my massage on her tits. She leaned down towards me, and began pumping herself up and down. She asked me what she could do to make me come. She kissed me and slid her tongue into my mouth. She was a good kisser, that was for sure. I grabbed her butt and began pushing up into her each time she lowered herself down onto me.
Just then the sliding glass door opened and someone came into the room. It was Mary, followed by several men. Mary had my shirt on, and it was wet. Her hair was wet. She was holding a guys hand. She led the guy to the center of the room. He helped her take my shirt off so she was completely naked. Then he held her hand as she lay down on the floor. The guy stripped naked and laid down next to Mary and started kissing her while fingering her pussy.
Mary spread her legs wide and began moaning, even while being kissed. The girl I was fucking had slowed down and was watching Mary and the stranger in the middle of the room. We were still fucking.
Soon the guy was getting a hard-on. He reached down and put Mary's hand on his penis. Mary gave the guy's prick a few strokes, and then her hand dropped away. The guy stroked himself a few times, then climbed over Mary and pulled her knees up next to him. He slid his prick into Mary's vagina. We had a great view between their legs and could see the action very well. Mary wrapped her heels behind the guy's back, and she began moaning very loudly.
The girl I was fucking began speeding up her pace, and said, "Look at her toes curl!"
