A girlfriend and I on vacation had met a couple a little younger than us. We seemed to hit it off and were enjoying time together. I could sense they were hitting on us and had mentioned it to my girlfriend who said I was crazy. But I caught him eyeing her little tits and ass all day.

At one point we were at their little rented cabin and going to clean up from a day at the beach to head out for dinner.
As the accommodations were tight we kinda took a corner each and were getting a Change of clothes ready and the ladies spread out make up and such.

The other couple went into the bathroom and started the water in the open large glass shower. As they came and went they left the door open quite wide leaving us a clear view in as they both stripped off, dropping their towels and stepped in together.

My girlfriend didn’t notice at first but I sure did. I am watching him soap up his naked wife. Soaping up her big tits he smiled and glanced at me in the other room watching.
Heart pounding and blood rushing.

When my girlfriend came over towards my side of the room she too then realized what was happening and arrived in time to see his wife take the bar of soap to his hardening member.

I was trying to entice my gf to perhaps join in but she laughed and giggled with embarrassment but chose just to watch.

When it came our turn we returned the favour and allowed them to watch as we washed each other’s sensitive areas.
They too respected my gf reluctance to mingle but watched us from the short distance. I was sure to give him a good chance to admire the little tits and full frontal views. The effect on him was obvious.

The last couple days we spent with much less concern to our state of dress but no interaction ever came of it but it was sure a turn-on being even that intimate together as a foursome. We swam naked together and enjoyed the sun and I wished we had taken the leap. But all good things come to an end.
