In the 19 years I've had sessions (18 years) have been with Strap-on play (Pegging). So I have a very comprehensive list of sessions that offer SO play.
Gayle Moher (1) strap-on session (She wasn't into it, she's a clock watcher and refused to do it again).
Sondra Faas (1) strap-on session (She was good, but she's 5'0, so it was harder for her even in 6 inch heels).
Amber Deluca offered and I was going to take it from her, but FS was on the table and I got sidetracked.
Cathy Conners (1) session ( It was ok, not the best).
BigTina H (2) sessions (Loves doing strap-on! She is so into it, she will pound you and you'll love it! Also CBJ!)
Lisa Cross (1) session (A literal fantasy come true! Also offered FS! So this time I got both FS AND SO!, massive woman! But a very expensive session).
Darkside Melinda (2) sessions (Tall girl, got it figured out (She's 6 inches taller in heels) real good at pounding, good attitude, open minded).
Demoika (1) session (Really good at it, she did multiple positions, really good at dirty talk).
Michelle Jin offered strap-on (She had never done it and worked with Samantha Muscle as a dom. However, I didn't end up as clean as I would like, so I passed. I didn't want to make her first a bad one. I don't think she's doing sessions anymore).
Samantha Muscle (1) session (She's a dominatrix, so yeah, she likes doing it. More of a fitness physique. Great provider, great pounding).
Tapered Physique (2) sessions (She just get's better every time. The first time she pounded me for 20 minutes, in 4 positions!).
Jennifer Scarpretta (1) session (Her farewell tour, so I thought I was in luck. I wasn't. She really gets off on CBT! It made it difficult for me and she only did strap-on for 3 1/2 minutes. Also, she went 0-60 mph in seconds, which made taking it real difficult! Easy does it lady, work me up to it. Still, if you like pain, she's for you).
Mistress Fernanda (1) session (Older lady, but enthusiastic. She's shorter, so on my back was incredible! Almost came from it).
There was one other provider, yet I cannot remember her name (From Ohio and was way out of shape), which is ironic because she gave me three prostate orgasms! The best strap-on ever (Not very dominant though, just hit the right spot 3 times!).
Those that said they would do it, but flaked on me. Rhonda Quresema (sp) (She fell asleep and missed session time, although to be honest she called back and said she would do it half price, but it was too late for me). Joanne Thomas, set up the time, she didn't give a call back for the hotel room. Melissa Coates, said she would do it, then cancelled tour date (Bummer, because she was a fantasy of mine from forever.) Nichole Pfumphauser (Sp), set up time and never returned call for room number.
