Yes, several times.

One Mistress, within the first 10 minutes of our session, rammed a vibrator against my cock while she pressed Her Pussy against it and commanded “I cum before you, get it?” I couldn’t…

Another time an incredible Mistress yanked on my neck collar leash tightly, pulling me up to her naked triangular heaven and instructed me to kiss her inner thigh, roughly 3” away from her pussy, while she quickly and expertly masturbated. This scene was so hot. I still think about it.

Another session with a Mistress who I have seen for many years instructed me to jerk off while she vibrated herself to orgasm. We laid on our backs in opposite directions. This experience was a little unusual for me at the time. I think she was trying to burn off a little excess energy from he life outside of the dungeon.

I often use masturbation as the ultimate in tease & denial. I have one slave who while in strict bondage drips an entire shot glass of pre-ejaculate. He drinks every drop before he is allowed to touch his dicklette!

It must take a long time to fill that shot glass!

I had better luck after tweaking the settings in the Device Manager and making sure the COM port matched what the program expected. Sometimes it's just a mismatch causing the issue.

Years ago, the Mistress that I served regularly would take a vibrator to herself while sitting in a chair. She would have me hump her boot and breath her scent while she was doing it. I was forbidden to cum until much later in the session. She would do this activity in about 50% of our sessions.

Yes. I’ve had this happen once in one of the best T&D scenes I’ve ever had. She would edge me very close to climax and then stopped to take care of herself. This happened 4 or 5 times in the same session and she claimed that she came each time. It was awesome and she was an incredible domme.

I also had many dommes tell me they can cum from strapon when the harness is positioned so it rubs on her clit while she is taking me. I’ve had many dommes claim to have cum this way in session. I’m not sure if it’s true or not, but in the early days, this one one of the best things I could hear. Such a mindfuck to know that I can get a goddess-like woman off, not through my own manhood, but by offering her my hole to use.

One time I was at a scene where a Mistress had me follow her moves really closely, and just when I thought I knew what was coming, she switched it up completely—kept me on edge the whole time. Stuff like that sticks with you. Sometimes after scenes like that, I’ll just chill online and watch some hentaiz for a bit—totally different vibe but calming.

My experience was a little different in that my Mistress came spontaneously. It was towards the end of a session and I was lying on the floor with nipple clamps attached to both nipples. My Mistress was standing above me and suddenly got the urge to grind her foot onto one nipple and then the other. I have a very loud void voice and I let out a wail to shake the rafters.

She was so pleased that she went and got her camera to take a short video of a repeat performance. Unfortunately, she was a bit disappointed and commented that my screams weren't quite as loud. However, she did reward me for my suffering. She knelt above me with her stained panties a nose length beyond my face, after saying "I think you will enjoy this". I went home grateful for what my suffering had produced. It was only afterwards, that I realized that I should have promised all my worldly possessions for her panties. I could have savored my pheromone fever for a little while more.
