I did a few showers in the late '90s with a young Mistress I was introduced to by a Mistress who was closer to my age, early 40s, and was retiring from the scene. The young lady was born in Jamaica but raised in Brooklyn. She was in her late 20s and going to law school - very intelligent. She had a physique like a track & field athlete - great legs, buns, strong back and shoulders who was gorgeous and had a beautiful smile. We did a "Tarzan / jungle princess" roleplay that after the first time began to be a switch session. It started out with her being slightly tied up, "Tarzan" saved her and midway through the scene, and then she became seductive and dominant.
We sessioned at her place mostly in warm weather - no A/C just fans. We were sweaty before, during and after a session. The first time we did it she got me in the shower before the session and she became the aggressor, laughing, feeling me up and I took over and did the same. She was not FS but very sensual so the showers after sessions were more intense, her soaping me up, me doing it to her, and treating each other like lovers. Very erotic stuff, things a traditional Mistress would not do - but some bodybuilders have done with me.
