Hot tub sex question

Emily
Hey so I've been on bc for a while now and I think it's safe to use the pull out method but my "sex fantasy" was to have sex in a hot tub one day and I want to this weekend but I was wondering when he pulls out and cums if it will like go away or be filtered away or will it be noticeable if he cums in the hot tub? Like wil it just float around?😂
