Nicole and I had been liveing together & swinging for some time.She was slim,strawberry blond,green eyes, honey colored skin. It made me smile just to day dream about her. We always talked about our swing dates ahead of time, so we had a loose plan for our fun.This time she wanted me to watch her with another man,I was to set nude close by and only watch.We had done MMF threesomes before but this was a new twist. I agreed,she picked a friend we had been with before and liked. The day our friend was coming to play she seemed a little more nervous than usual,I thought it was just pre-show jitters.And she was fine when our partner showed up.Nic had us set the stage,a large plush blanket on the floor my leather covered tubular steel chair next to it. I had to undress myself and take my place in the chair. They undressed each other and began with oral sex changeing positions and moveing ,so that I would have a clear view. It was beautiful to watch. I became very hard.When she was ready,she turned him on his back,got on top of him,Looked directly into my eyes,reached down, and penetrated herself with his cock.She never moved her gaze off me.She settled herself onto him ,I could tell by her expression when he was all the way inside her. She was radiant I thought I would cum just from looking at her. Then her eyes changed,her disposition changed she laid herself onto him kissing him passionatley on the mouth, neck ,chest,thrusting herself onto him. She came spasming,her back arching up so I could see her abs contract.Her face would hit his chest and rebound a little to match the puffs of her breath. I wanted to grab her by the hair,and yank her off him.I wanted to stomp this guy into a puddle.I bent the arms on the chair,then I was Paralized, there was a tear running down my cheek. She lifted her head,then came toward me and pulled herself onto me in the chair, her knees still on the blanket.She smelled like heaven. Her breasts moveing along my penis made me erupt When she came to rest on me,she was covered with me.I was shaking. Nicky kissed the tear off my cheek,and said"I love you."put her head on my shoulder,said"that was intense."
