Have ended more than one session (both escort and massage sessions) with a joint shower, always hot. I remember a session with a very hot escort. We made out and I topped him. He offered a mutual shower. Although I'm usually soft for a while after cumming, showering with him brought me to full attention again. He said: "Well, we can't let you go home still like that!" and made sure I got off again right there in the shower in an exquisitly erotic experience. Nobody was keeping track of time, but he didn't ask for anything extra although I did tip generously.
