Part One:
By way of introduction, I met Sean's wife, Beth, where I worked a long time ago and we became close friends. She was a really cute girl with slim body and smallish breasts. We both tended to be sexual in nature so most of our lunch conversations would be about sex. We knew we could trust each other so we felt comfortable sharing intimate details about our sex lives which I loved doing. Her husband Sean is really good looking, over 6 foot tall, very masculine, he played college sports and is still in great shape. And he was very much an Alpha male.
We started double dating with our husbands and Nick and Sean became really good friends. I guess Sean was strongly attracted to large breasted women so he had a thing for me and would flirt and tease me a lot on our double dates.
Our favorite double date was to go to a local bar which featured great food and a really nice, dark dance floor and great sound system. Often they would have guest performers and there was always a good crowd there.
During our visits there, Nick and Beth would chat at the table and Sean and I would dance and then one night Sean got a little carried away and started secretly groping me. I thought this was a minor thing where he'd had too much to drink so I didn't make a fuss, but over the next few visits to the bar, as Sean and I would dance, he'd regularly rub his hands over my ass and even squeeze it and occasionally over my breasts, which was "mostly" harmless, but still a little alarming.
I enjoyed his touch but I still asked him to stop. Shaun said it was OK since he'd caught Nick secretly watching and since Nick never said anything, Sean surmised Nick liked to watch and was OK with Sean groping me. I was a little surprised so I asked Nick about it later on the way home and he said he had noticed Sean touching me, but didn't think it was a big deal, he thought it was kind of a turn on seeing his wife felt up in a public place and he said besides, it looked like I enjoyed Sean touching me so he was OK, if I was OK with it.
I also mentioned it to Bethany and she said she'd rather it be me that Sean got frisky with and not some stranger since she trusted me that I would never do anything to intentionally hurt her so she felt safe if Sean wanted to blow off a little "steam" with me.
On our next double date, I told Sean what Nick and Beth had told me which inadvertently gave Sean the green light to touch me and as long as he mostly behaved himself it was alright with our spouses, which is exactly what he did. Often times during these groping sessions, I would feel Sean's cock pressed against me. It seemed big, but without touching him there, there was no real way to tell and I had made it a point to not touch Sean inappropriately. I never wanted Nick or Beth to think I was the aggressor and I worried that once I got really aroused and responded to Sean by touching him back, I was afraid I wouldn't be able to stop and things would get way out of hand.
Eventually, when Sean had a good buzz going, he tested the waters to see how far I would let him go while we danced. One night during a set of slow dance songs, with one hand on my back to hold me close to him, he put his other hand under my top (that night I wasn't wearing a bra) and he groped my breasts and tweaked my nipples. When I didn't make him stop, he got even more aggressive. I was feeling frisky, and him knowing that I was turned on, his fingers found their way under my short skirt. He groped my pussy and ass for a bit and then he slid my thong panties down and off my legs and left it on the dance floor.
I was already moist as he stroked up and down my slit and eventually he slid two fingers into my cunt gliding in and out while he used his thumb to tease my clit. I was getting very aroused with him taking full control like that him knowing I wasn't totally comfortable him using me like that, but too weak to make him stop. I looked around and noticed two other couples near us watching with my skirt lifted and Sean's hand caressing me, and that made it even more erotic. I just rested my head on his shoulder and enjoyed him touching me as he held me close to him. He could tell I was getting close to climaxing as well as those watching by the moaning sounds I made.
I climaxed just before that song was ending and when I finally got my self control back, I asked Sean to stop since I needed a break and for us to sit down. Once back at the table, I made the excuse of not feeling very well and asked Nick to take me home.
On the way home, Nick asked me what happened and I told him exactly what Sean did. Rather than get mad, Nick got really excited and asked me to pull my skirt up and show him I wasn't wearing panties and then he reached over and put his hand on my pussy to play with me as he asked questions, wanting all the details like how did I feel letting another man touch me intimately, bringing me to a climax, and how did it feel knowing that people were watching us. I was honest with Nick and said that I really enjoyed Sean taking full control of me. Knowing that another man was doing it only made it nastier and therefore even more erotic.
I noticed that Nick was really aroused by my answers about Sean using me that way. He confessed that he did find it very erotic that Sean touched me like that on the dance floor. His only regret was that he wasn't sitting where he could have watched. I confirmed with him that if he had been able to watch, he wouldn't have tried to stop Sean and he said no. I should have realized he'd be that way. He's always trying to get me to expose myself in public so others can watch. I dropped the subject there, but put in my mind that Nick was not done with this.
