As we entered Lisa's apartment I asked for the location of the restroom, she pointed me down the hall as her and my wife went to the kitchen to make a couple more drinks. When I returned to the living room they were both on the couch, drinks on the table in front of them. My wife's top was already off, her big breasts held in by a lacy black bra, Lisa's jeans were down to her ankles and I could see a wet spot in her pretty white panties. My wife was caressing her thighs and Lisa's hands were all over my wife's tits as they kissed each other, tongues entwined together, breathing heavy and moaning slightly. I took a seat in a plush chair across from them and rubbed my stiffening cock through my pants.
They continued to undress each other seemingly oblivious to my presence. They both had great bodies well equipped for sex and I was enjoying every minute that I was able to watch them. Lisa had two fingers in my wife's pussy now, my hot wife's hips were bucking and she was moaning and trembling. Karen was rubbing Lisa's clit with her finger, and then she made eye contact with me, licked her lips, and nodded in the direction of Lisa. I took that as my invitation to get involved. I rose from my chair, quickly covered the few feet between me and these sexy creatures, and knelt down between Lisa's legs. My wife's hand moved away to pinch Lisa's nipples and I took her swollen clit between my lips sucking it gently and running my tongue across it. Her pussy tasted very much like my wife's with only a subtle difference. I slid a finger into her wet hole while my tongue danced on her clit. It must have been quite a while since she had had sex because under my skillful tongue she came in less than a minute. All the while Lisa's fingers sliding in and out of my wife's pussy, rubbing her clit, teasing her nipples.
Now it's my turn, said my wife. She rose from the couch eased me out of the way and placed herself between Lisa's legs. She's always wanted to eat pussy, and as she did she put her ass in the air and wiggled it at me. Knowing my wife like I do that was my invitation to fuck her. I positioned myself behind her slid my cockhead against her wet pussy and clit lubing it up with her juices. The head of my cock slid easily into that familiar wet hole. I used long strokes, sliding it slowly in and out allowing her to enjoy Lisa's pussy without too much interference from me. Before too long my wife started to moan her hips bucking against me while she devoured Lisa's pussy. I could feel her pussy contract around my penis as she started to come. She moaned and whimpered as my cock drove in and out of her bringing her the ecstasy she so deserved. I wasn't ready to come yet and I could hear Lisa asking if she was going to get fucked too.
My wife turned and looked at me, gave me a slight nod and mouthed the words I want to watch. She got up and moved to the chair I had been sitting in earlier. Lisa was lying on the couch with her legs spread, I leaned over her and kissed and sucked both of her nipples, while pushing down on her thighs to open her legs wider. I rub the head of my cock on her pussy lips and her clit just like I had done to my wife earlier to make sure she was wet. There was really no question, she was practically dripping. I slid my cock inside her and she let out a low moan. I started to work it in and out, the same long strokes that I had just used on my wife. It wasn't long before she startled to tremble and moan louder, her feet flexing madly as I fucked her. I paused once to look over my shoulder, Karen was watching intently, furiously stroking her pussy as she watched her loving husband fuck another woman.
They both came nearly simultaneously, Lisa bucking her hips and crying out underneath me as I plowed my cock in and out of her, my wife moaning louder and louder sitting behind us in the chair. I could feel my balls start to tighten and knew I wouldn't last much longer my wife seemed to sense it as well and asked me not to come inside Lisa. I pulled out of her and stood, stroking my cock, ready to explode. My wife rose from the chair and came over to us, grabbed Lisa's hand and pulled her off the couch. They both knelt in front of me and started to lick the head of my cock.I couldn't take it anymore and started to shoot blasts of hot cum onto their faces and into their mouths, until both their faces were streaked with my hot juices.
We all went to the bathroom to clean up a little bit, had a drink, rested, and then we excused ourselves, thanking Lisa for a great time. I'm pretty sure she and my wife exchanged numbers so maybe we'll get to do this again sometime.
