I met Mark and his wife Sharon through a swinger’s ad I’d placed in a local paper.

Sharon liked me so much that she called in sick to work so she could be with me. I showed her a few things she hadn’t tried before and was now eager to show Mark. When they invited me over for a session with both of them, I already knew what the game plan was. I left it up to Sharon to give me my cue when to begin.

To start with, Sharon sucked Mark until he had a firm erection, then had him lie on his back. She straddled his waist and slowly sank her cunt down to engulf his hard-on. “Mmm, baby, you feel so big, but I think I can take some more,” she said. “Joe, see if you can put your cock in my ass. I’ve always wanted to try two at once.”

I did as she asked. Sure enough, there was room for both of us. Not only did Sharon’s pussy massage Mark’s prick as he slid in and out, but I too felt Mark’s prick through her anal walls as I alternated my steady thrusts with his. It was so hot. We continued like that until we’d all come, then we cleaned up and switched positions.

Mark sat up at the head of the bed with Sharon lying between his legs so she could lick him clean. I got between her legs to eat Mark’s come from her drenched pussy. Sharon has the wettest pussy of any woman I’ve known. Once I had all the come out of her that I could get, I slipped my cock into her pussy. I could never get enough of her pussy. Now my head was right next to Sharon’s, where she was sucking Mark. Sharon took turns sucking Mark’s cock and French-kissing me. Then she concentrated on making Mark come, and sucked down Mark’s hot sperm when he shot off in her mouth. This was Mark’s second come of the day, and he was completely worn out, but Sharon and I still had energy to burn. She suggested that I keep up the good work.

Pretending that she hadn’t had it from me just before, Sharon said, “Sucking off Mark has gotten me really horny. Would you like to put your cock in my ass again, Joe?”

We were soon going at it, just the way she wanted. This got Mark interested, so he walked around the bed to where he could get a better view. He started stroking his cock as he took in the sight of my prick going in and out of his wife’s ass. Having used Sharon’s really slippery pussy juice to lubricate both of us, my cock had no trouble sliding into her nether hole. I gripped her hips to give myself good leverage for pounding into her. From previous experience with Sharon, I knew she would want me to increase the force of my thrusts. Once I’d introduced Sharon to anal sex, she couldn’t get enough and had my cock in her ass at least once a day, which was fine by me. I’ll take all the ass I can get.

It came as a surprise to Mark, but the sight of my cock sliding in and out of Sharon’s ass had given him an unexpected urge to come for the third time that day — a record for him. He got up on the bed and stood over Sharon, placing his hard eight-inch cock at her eye level. “Suck me off again, Sharon. Seeing you get fucked in the ass has really gotten me horny, and it felt so good when you sucked me off the first time that I want you to do it again.”

I was in seventh heaven. I had my cock up the ass of a woman who really appreciated ass-fucking as she sucked her husband’s prick. It was all I could ask for.

Sharon was the first to come this time. Still working on Mark’s cock, she used her right hand to play with her clit. Even with her mouth full, her moans of pleasure filled the room. Mark and I were soon to follow as the squeezing of Sharon’s ass muscles set off my own orgasm, while her increased sucking sent Mark over the edge as well. Mark’s come filled Sharon’s mouth as my come shot into her butt. Mark lay on the bed as I pulled my cock from the embrace of Sharon’s ass hole.

“Whew! You two are something else,” I told the married couple. “Anytime you want to have sex, just give me a call.” I left them to relax and found my own way out.
