"Well, well, well, look at the situation the both of you are in." Ariel's demeanor had shifted. She still had a teasing attitude but there was wickedness behind her smile now. She is moving to the side of Lexi now and out of my vision.

"Lets get you both warmed up shall we?" She purrs and I can hear her moving something metal.

Within in my line of sight, she reappears carrying some type of metal arm device. She attaches it to the side of Lexi's chair at about hip height. She leans between Lexi's legs, parts her pussy lips with her left hand, and starts rubbing her clit with the right hand. There was no warm up before these actions, no foreplay, just direct stimulation. This only lasts for a few seconds and she backs away.

Ariel walks out of sight and then comes back, this time she has a Hitachi vibrator. She attaches this to the arm apparatus and maneuvers it so that the head of the vibrator is touching right on Lexi's clit. Ariel clicks the vibrator on low. Lexi's head tips back and her eyes close.

"Oooh yeah!" Slide from her lips followed by light moans.

"There you go baby. You really like that don't you," Ariel seems to be cheering her on. Ariel turns her head to me and her eyes squint.

"Carl, you look lonely over there. Do you need some attention?" she asks as she starts slowly moving over to me. I nod my head enthusiastically and my cock seems to follow by bobbing up and down also.

She is next to me now and chides, "Poor baby, having to watch Lexi enjoy herself over there and not have any stimulation. Let's change that for you."

The index fingers of her hands touch each of my shoulder blades at the same time. She begins to drag them down a bit and then starts to draw patterns into my skin. The light tickling continues and occasionally crosses my nipples sending shocks through me.

My mouth is closed but I still lightly moan making, "Mmhmm," type sounds. I have enough sense left to notice that my stimulation is the exact opposite of Lexi. She went from no stimulation to overdrive, I was being slowly stimulated. I am relaxed and almost feel like I'm day dreaming until my concentration is broken.

Lexi screams out, "Fuck yes!" from across the room.

My eyes open and I am drawn back into what is happening. I look over at Lexi and notice that she is sweating. Her face is flushed and her eyes are squeezed shut. Ariel leans in and starts kissing my neck. She moves up and is nibbling on my ear as her hands are tracing the sides of my ribs. This light tickling elicits a giggle from me.

Ariel stops suddenly, "Oh my Carl, are you ticklish?"

I look worried and yell, "NO."

It's too late though because I feel her fingers start digging into my sides. My laughter is uncontrollable as she tortures my body with her dexterous fingers.

"Please stop!" I yell in between gasping for breath.

The tickling suddenly stops and Ariel walks back to Lexi. I'm breathing heavy and this has left me so horny that I actually try the bonds on my hands again to see if I could get them free and touch myself. It's no use though because the bands are very strong.

Ariel is next to Lexi now and begins plunging two fingers into an out of her sopping wet cunt.

"Yes,.. Yes,.. Fuck-me, Fuck-me..." Lexi is yelling this over and over.

Ariel stops when Lexi quiets a bit. She moves a large machine in between Lexi's legs.

"You should be wet enough now for this," Ariel says as she lovingly runs her fingers across the machine. A large piston comes out of the box portion of the machine. The end of the piston is tipped with a large purple dildo.

The dildo is eased into Lexi's pussy.

"Oooo yeah!" she moaned as this happens.

The vibrator is adjusted so that it has maximum contact with her clit. The fucking machine comes to life and starts to piston in and out at a rate of two thrusts per second. Lexi was loud now: yelling, swearing, and even calling out to god!

As Ariel moves back to me she grabs two items from a table that is just out of view.

"Carl, you are really horny aren't you?" I nodded yes.

"Well, we need to make sure that you don't cum the second I touch you. Just watch how sensitive it is right now." She leans over near my cock.

Oh my god all she would have to do is touch her mouth to me and that would be enough. Instead she pucked her lips and blew across my engorged head, beads of pre-cum trickle out and my cock throbs.

"See! You are near the edge and I haven't even touched you. These will help." I feel her hands roughly grab my balls and pinch them in a circle that her thumb and index finger made. I feel something tighten around my balls and then a weight pulls down on them drawing them far from my body.

Next, she looped an adjustable cock ring around me and tightened it as much as she could. God, I thought, my cock is so hard now that it is almost painful.

"Fuck... Me... Fuck... Me... Oh God! I'm cumming again!!" This chorus punctuated by a melody of screams and moans echoed in the background.

"I have one more thing to help you stay very excited." Ariel says far too enthusiastically.

I could see that there are wires attached to the cock and ball ring and they were plugged into a device that has three lights: green, yellow, and red. The green light is currently on. Ariel places her index finger right on my cum-spot (that area under a man's cock right at the cleft in the head). She moves her finger up and down lightly over my cum-spot for maybe two minutes. My arousal is starting to burn and I feel my orgasm building. The green light goes out and the yellow comes on.

"You see Carl, this measures your arousal level. Green is for slightly aroused, yellow you are close to peaking, and red means you are literally at the edge of orgasm. I'm going to keep you at yellow for a bit while I take care of something."

She grabs a bullet vibe and straps it to the underside of my cock. She turns it on low and pulls a chair up next to my head.The room is very warm by now and everyone was sweating. Lexi's song of blissful orgasms is still playing in the background. Ariel spreads her legs and parts her pink glistening cunt lips. Her sweat and pussy juices mix together to form a pungent and appealing smell. Ariel's fingers work in a circle over her clit while three fingers from her other hand are inserted into her. She works herself over at a quick and fevered pace. Soon her muscles are taunt and defined as she spasms in orgasm. I notice that she is relatively quiet, or maybe I can't hear her over Lexi.

Ariel reaches over and lets me lick her cum soaked fingers. It is like receiving a shot of strong pheromones into my system. I feel the pressure build and I am just about to cum. The red light turns on and the vibrator is turned off. I hang there right on the edge of a tremendous orgasm for a few seconds and then vibrator turns on again. It switched off almost immediately as I went right back to the edge. On again, off... on... off... it is like bolts of energy are shooting through my cock and into the rest of my body.

"Please let me cum!" I yell, finally mixing my voice with Lexi's.

The vibrator stops and is removed slowly. I feel a hand tighten around my cock and start to pump. "Yeah, Carl cum for me!" Ariel cheers.

"Hey Lexi do you want Carl to cum?" she yells across the room. The only reply is screams and whimpers as Lexi cums for maybe the 12th time. Ariel Strokes until the red light comes back on and stops. Just like with the vibrator she did this over and over again.

I am also loudly expressing my sexual frustration. At first, I try to bargain with Ariel. Then I am just begging and pleading over and over again to cum. Finally I am reduced to just incoherent outbursts.

Ariel finally stops and I slowly start to cool down off the perpetual edge I had just been on. I hear the fucking machine and vibrator turn off. Lexi is lightly sobbing in between saying thank you. This does not last for long though. A much larger dildo is being attached to the end of the fucking machine.

When Lexi saw this she started begging, "No... please, I can't cum any more please."

Ariel wiped the sweat from her brow and said, "Don't be mad at me, this is Carl's fantasy. He is the reason that you are being subjected to all of this."

"Fuck you Carl!" Lexi spat at me. She couldn't say anything else though because the giant dildo is being pushed into her far too sensitive pussy. The vibrator is placed back and both machines went from off to top speed in an instant.

"FFFUUUCKK!" Lexi yells. Ariel moves a machine between my legs. It looks similar to the one between Lexi's legs except it is tipped by what looks like a flashlight. She lowers it onto my sensitive cock.

"Carl the machine is plugged into the orgasm sensor. It will turn off when the red light comes on. It won't get tired nor will it show mercy." She turns it on and it starts to pump over my engorged and angry cock. There also seems to be suction on my cock. I know it won't take long before I am at the edge.

Ariel is sitting next to me again. This time she has a Hitachi vibrator of her own.

"Carl, I'm going to get myself off over and over again until I can't stand it anymore. Only when I am finished, will I turn off the machines on Lexi and you."
