On our trip away we were swimming in the pool, and saw loads of couples pulled really close to each other. Jokingly, he quipped: “You probably wouldn’t even be able to tell if they were having sex right now.” So without saying a word, we decided to try it out. In the middle of the day, in our hotel’s pool. I pulled his cock out and he was hard in an instant. I jerked him as he had his fingers in my bikini and fingered my pussy. After a few mines he lowered my bikini bottoms and pushed himself inside me. The thrill of doing it in the open was so fucking good I came in minutes. He came inside me and quickly pulled up my bikini bottoms and tucked his cock back in his swimming trunks. No one noticed a thing. We did the same in the sea later.
