I have told this story before but will do it here without names due to the activities involved. I got into BDSM not really knowing what the hell it was. I was a 20 or 21 yr. old commuter college kid, living at home with little money. Saw an ad in Screw Magazine (this was in '73 or '74) with a hot mature woman in a B&W pic in leather, with short blonde hair and was busty. Horny, and without a date in a few months, I called. We discussed role play. She worked out of a storefront near NYU in Manhattan. Looking back on the experience she had to be late 40s and damned sexy. She asked if the role play was going to be her as a stepmother, next door neighbor, etc. I said I'd be a shipwrecked sailor (wore a homemade thong of rags) and she'd be the Jungle Queen. She came in wearing a black leather corset and high heels. I learned the joy (and technique) of giving oral sex and, at the end, received the same. Yes... it spoiled me for life. LOL! So I never had a problem with serving a Mistress older than me. I had a two, three sessions with her after that, left the scene until the '80s and she recommended Mistresses that worked for her. Most were my age then (mid-30s) or slightly older. By the '90s I hadn't seen my first Mistress in quite awhile and called her dungeon. She answered and I immediately said I wanted to session with her. She said no, but I talked her into it. I was then early 40s, she had to be close to 70. Still as sexy as ever, so I had no problem with older women.
But now I'm just past 70. In good shape for my age, but when I passed 60 I decided not to session with a lady under 30. I began to think that the ladies were the same age as nieces, daughters, co-workers I had so I stayed away. (Now, no one under 40.) I haven't had to concern myself about that the past few years. I now exclusively serve, and owned by, a now under-the-radar Mistress I originally met around 2000. She looks far younger than her years, but she is in her 60s.
