A few years ago myself and my then girlfriend Lisa were away on holiday in a seaside town in the UK. We had ventured out for the night after having a few drinks at our campsite and ended up in a loud bar with a dance floor. Lisa liked to dance.
We had a few shots and were feeling pretty tipsy. Lisa was always very flirty and she didn't hide it, this secretly turned me on. She openly flirted with the barman whilst ordering our drinks.
After I returned from the toilet I found her talking to a guy by the bar, he was obviously trying to chat her up and she seemed to be encouraging him. I thought I'd hang back and watch to see what happened, but he eventually took off with his drinks and she looked round to find me.
I asked Lisa who she was talking to, she said his name was Rob and he was also on holiday! I asked if she fancied him and she replied "sure, he's fucking fit."
We danced a bit and got a bit more drunk, then we found somewhere to sit. We kissed and Lisa started feeling me up through my jeans, I ran my hand up her short skirt to her wet knickers. "Wow" I exclaimed, "something's got you all horny I see." She smiled.
I said "Or is it someone?"
Lisa didn't deny that she had the hots for this guy, she told me that if I wasn't around she would have pulled him. I knew from our first encounter a year previously that she would have fucked him too, because she fucked me the night we first met.
I was so horny at the thought of her and this other guy that I said, "why don't you go and see if you can find him?"
"And what would I do if he came onto me?" She said
"Whatever you want babe." i replied excitedly.
We talked it through for a minute and she said, "ok fuck it, I'll go find him, but you better not be angry with me if something happens."
I assured her that I was cool with it and she kissed me deeply, winked at me cheekily, "wish me luck" she said as she turned and walked away.
There was a balcony overlooking the dance floor, I waited there, looking down as Lisa went to the bar where she had met him. I could see her standing at the bar, she ordered a shot from the barman and chatted to him for a while. I stood and waited nervously, watching to see if this guy was about. Then a few minutes later someone approached her. It was Rob!
My heart was pounding, wondering what would happen. After a minute or two of talking I saw her take his hand, they walked to the dance floor. She had her hand round his waste, holding him close, girating against him. I saw his hand on her bum and I could feel my cock stiffen as I watched from afar. Then they kissed!
She danced with him for a few more minutes when I saw them walk away from the dance floor, down towards the exit and out of sight.
'Fuck' I thought, there was a tinge of jealousy mixed with a shit load of hornyness.
