I like going to the swimming pool and sauna with my gf. One day we were alone in the whirlpool until two other men joined in a few minutes later. My gf was relaxing near me with only her face and chest pointing up, her eyes were closed .One could easily see how her boobs in bikini would move with the water. She didnt care . I enjoyed watching her while other men could also see her hot body . Of course, since it was a public pool, nothing more happened. In my head though, I imagined the men getting closer and closer to her, starting to caress her body and removing her bikini top. One would start playing with her nipples while the other would stand up and pull his erected cock out and invite my gf to suck him off.
