I lay on my back as Jan straddled me and then slowly lowered her dripping pussy onto my erection. I gasped as my knob slipped easily into her wetness. Once again I was enjoying the extremely erotic sensations of sloppy seconds and I had to fight for control as my cock slid into the warm, silky tightness of the cunt I loved so well, knowing that only minutes before another cock had enjoyed these very same sensations.

This was our third night with Terry and at the start of the evening Jan had announce that tonight would be Terry's night, he could do and have anything he wanted. I think without saying more we all knew what she meant. Earlier that day Jan had told me that during the previous nights lovemaking Terry had worked his complete finger into her anus and had whispered, "I would love to get my cock up there!"

Initially I had felt a twinge of jealousy, as Jan had never encouraged my attempts at entering her back door. We had experimented a bit but I had never got more than an inch or two inside her before the tightness made it uncomfortable and so over the years I had never pushed it further.

And now as Jan slowly pumped herself up and down on my shaft Terry was taking in the sight before him. Sitting opposite he had a great view as my cock slid right up inside her cunt then slowly emerged, glistening and shiny with her juices. But what must have been more tempting to him was the sight of her arsehole slowly opening and closing with her movements. Jan must have planned this as she put her hand around behind her and opened the crack of her arse so he got a better view. She wiggled her hips, tempting him, enticing him. He needed no second invitation and he was soon standing behind her. She pointed to a tube of lubrication indicating once again that she had a definite plan in mind. It didn't take him long to have her tight little entrance all slippery with the lubricant and rolling on a fresh condom he slowly began working his knob around her puckered little hole.

Jan continued to wiggle her hips inviting him further into her. Soon he had the knob inside and I felt Jan stiffen as he worked it slowly deeper into her. I tried kissing her to show my encouragement but her face was distorted in a grimace of both pleasure and pain. His hands were around her and his hands were massaging her perky little breasts as his fingers tweaked her nipples.  So I lay back and watched. There was something very erotic about the contrast between his black hands and the whiteness of her breasts as he rubbed and played with them. Knowing his black cock was slowly penetrating her rear end was blowing my mind and I lay motionless as I felt more and more of it sliding in.

What had surprised me was the thinness of the walls between the two passages. I could plainly feel his cock pressing against mine as he worked it slowly in and out.......pushing a little deeper with each stroke. When I felt his knob rubbing the underside of my own cock I felt another twinge of jealousy knowing he was much further up her anus than I had ever been. She gasped out loud as he pushed his full length inside her. I knew it was hurting her but I also knew she had become very emotionally attached to Terry over
