I'd put an ad up on CL asking if anyone knew about e-stim. I didn't expect much given my area seems very vanilla so I was surprised to get a reply on the same day.

After the usual pleasantries, pic trading & "nuts & bolts" of the operation we set a date and a place to meet.

when I arrived at the location I was surprised to be greeted at the door by an older, normal looking lady. I asked if "jim" was home. She knowingly said he hadn't arrived yet but I should come in & have a seat.

I was surprised again to see a younger lady sitting in the living room. I introduced myself & they smiled knowing I was confused. The older lady asked what I was there for & I said to meet Jim, we'd talked online & agreed to meet today.

"for what" she asked

"um..." I stammered

The younger woman laughed and said "He's here to get his ass beat"

I immediately made clear that no, i wasn't there to get my ass beat, rather try out an E-stim

"how do you know about e-stim" the older lady questioned

"the internet" i said at the same time as the younger woman & we laughed. the ice had been broken & we were all getting comfortable by the time Jim showed up.

The older lady explained she was a dominatrix & had a dungeon in the basement. astonishing, given her outward appearance.

So to the basement we went while the younger one said she was going to change into a bikini & lay out back for some rays.

Mistress wasted no time ordering Jim & I out of our clothes while she readied her device.

"put this on" she told me, handing my a closed plastic ring I was sure i would never be able to get my set through. I tried but eventually she had to get me through it, manhandling my cock & balls in a rough, clinical manner.

Unfortunately, only one of the E-stim machines seemed to be "firing up" so Jim & I would have to share the stereo unit. He easily slipped his junk through the other ring, surprising considering his endowment.

There we stood completely naked with plastic rings around our cocks when mistress told me to go out back & get the younger woman to help.

"um..should I put something on" I asked

"go get her!" the mistress demanded

I went. I'd never been involved in this sort of play & I think she especially enjoyed ordering a newbie.

So out I went to the back yard, buck naked, to ask a bikini clad babe if she didn't mind helping. all I could think was WOW!

I returned to the dungeon to see Jim lying on the small bed getting a wire attached to the ring around his cock & balls.

"shall i sit here?" I asked referring to a stool nearby.

"No! get up on the bed next to him"

There was barely enough room for one so I got up on the bed nearly on top of Jim. She attached a wire to the ring around my cock & balls too & started the machine.

"let me know if it starts to get to be too much" she said.

I felt nothing. then slowly I felt a tingling sensation & Jim moaned.

"more?" she asked & we agreed "yes"

after a few more seconds I felt the tingles turn into a pulse, flowing from my perineum, through the shaft of my cock & straight to the head. I hardened instantly & my cock twitched as the machine pulsed relentlessly in a seemingly random rhythm.

"there, that's full blast" she said

It felt good, for a while

"do you like it?" Jim asked

"I'm starting to go numb, I think" the vibration became so consistent that I couldn't feel so much the pulse and everything started to tingle, like when a foot falls asleep almost

"well," the mistress said, "rub each others cocks"

Jim & I grabbed each other & started stroking

This is when the younger woman came down the stairs wearing a sheer black & red lace teddy.

"wow, looks good" she said, watching Jim & I play with one another

all the sensation had my hips bucking & Jim moaning

Mistress ordered her assistant to get the lube & squirt it on our cocks. I notice Jim playing with mistress's tits with one hand & stroking me with his other. The sensation & the visuals were sending me higher. I stroked Jim's thick cock wondering if I'd be instructed to suck it. Or hoping. but before I got the chance, Jim started breathing heavy & blasted a thick load up & out of his balls with a long moan, bucking his hips & fucking my hand.

My hand was covered with Jim's thick goo. He got up handed me a towel, got dressed & left. Mistress followed him out. I was left alone with the younger woman, wiping my hands of his load.

I laid there on the bed & started to stroke myself again while she watched in silence. I looked at her with her big tits pushed up in her lengeri & smiled wondering if she was just gonna watch or...

that's when she asked if I wanted some help.

"oh hell yeah!"

she re-lubed my cock & started stroking.

I asked if I could play with her tits and she obliged. my hands groped her for a minute then I slipped one hand underneath & played with her pussy from behind while she stroked my cock with both of her hands.

"wow! you last a long time" she said, wiggling her ass a bit. Her body was tan & curvy but tight & I was loving it.

She started talking about all the people who come down to the dungeon & what they do as she continued to pull at my cock & massage my balls.

She pulled her top down a bit to let her big tits sway with her motions & bent down a bit so her nipples lightly brushed against my thigh. That's when I blew a giant, pent up load all across her tanned boobs.

It took a minute to unhook from the machine & she helped me out of the ring. I laid there for a while coming down from one of the biggest orgasms I'd ever had.

What an experience!
