Bach to your original, Tosh. When I was 20, I ate (drank?) my 18 year old girlfriend underwater in her parents' pool when they made the big mistake of leaving her alone for a weekend. The pool was surrounded by a privacy fence, but even though her parents were gone and nobody could see us, she was nervous about getting caught. I finally convinced her to just slip off her bikini bottoms while we were both in the pool, and I went down on her (literally). Sounded like a good idea, really hot, and a little voyeuristic, but really not so much. Too much work to stay down, and I couldn't taste anything but chlorine.
In the end, we went inside and finished the job on the couch. Thank god for trusting parents!
Never have I ever.. had sex with two women at once. Boring for these parts, I know.
