My friend’s girlfriend organized a weekend trip for a few of us to celebrate his birthday. The first night was a lot of fun, we all enjoyed the party and spent time in the hot tub.

The next day everyone left around mid afternoon except for me and the two of them. We had dinner and headed out to the hot tub again. Drinks flowed freely and after a while my buddy took off his trunks and tossed them out of the tub.

He dared us to do the same and I went along and was surprised to see that she did too. She kept her top on but tossed her bottoms out. You couldn’t really see anything under the water and we all just laughed.

After a few minutes he dared her to ditch her top and to my surprise she did. She had really big tits and I was happy to get to see them. She slid over closer to him and her hand disappeared under the water and I could tell she was jerking him off. A few minutes of that and they’d had enough foreplay. They stood up and he bent her over the edge of the tub and began to pound her from behind.

I moved around out of the tub to get a better view and started to jerk off. It didn’t take long before I came and he wasn’t far behind. We all laughed about what happened and the rest of the night was pretty uneventful.
