The vibrator is moved to her ass

"So, as an extra little penalty for completely lacking self-control, I think we need to give that ass of yours a little of the same treatment that your pussy so thoroughly enjoyed!"

A bedraggled Tanya looked up and started to protest, but Rachel dismissively waved away her concerns, and strolled over to where she'd placed a small bag.

She bent down and pulled out a large black object, with several straps hanging off it, and gave Mitchell an evil look.

"Just be thankful Tanya had such little self-control. Had she won, I was half of a mind to peg you instead, as a little prize for your girlfriend."

Mitchell stepped forward, as he realized what Rachel now intended to do. As he watched her begin to fasten the strap on dildo around her pelvis, he shook his head vigorously.

"Do me then!" he said, finally finding his voice, "Leave Tanya alone and do me in my ass! Bend me over, strip me, fuck me from behind, whatever your want! Please!"

Tanya looked shocked at Mitchell, but Rachel was having no part of Mitchell's small efforts to save Tanya further embarrassment.

"Now, now, fair's fair. She lost, so she has to take the penalty." Rachel said, playfully applying some lube to the dildo, and then taking a small handful of the gel and not-so-delicately shoving it around her red-headed plaything's anus.

"Besides, she's already worked up as it is, so it probably won't take too long for her to lose control yet again!"

Without any further negotiation, Rachel took her position behind the still-shaking Tanya, and pushed the woman down on the top of her back so she bent at the waist. With Tanya's legs still spread and the dildo-pole still impaled inside of her, there wasn't many places she could go. The only saving grace was that now it was turned off, the dildo on the poll was slightly more flexible, so her sore pussy only slipped a little on the juice-covered device.

Tanya remembered back to being in the stocks at the convention, and the way that Rachel had shoved the hook into her ass. The way that she'd felt the smooth implement slide into her virgin ass while a crowd of convention goers looked on.

She felt a new wave of humiliation sweep her up as the end of the strap-on first touched her bottom, and then began to push in, deeper and deeper as Rachel took full advantage of her predicament.

Tanya looked forward and saw that the camera was still on. Of course it was, she thought, there was no way that Rachel would let her audience miss out on this.

She grunted loudly and in shock as Rachel partly withdrew and then pushed in again, the lube going deeper into her ass as the first thrusts of the strap-on began to do its job.

Seemingly satisfied that she wasn't going to receive too much resistance, Tanya then felt Rachel grab her long red-hair, and then begin to find her own pace.

Tanya groaned, and a little bit of drool began to run down her chin as she found herself repeatedly pounded by their tormentor.

After what felt like minutes of rough treatment, and with Rachel more than happy to pull Tanya's head back by her hair if she let it drop down, Tanya then felt an awful sensation. She could feel the rich, exquisite humiliation of the scene began to turn her on again. With a slow, agonizing inevitability Tanya realized that Rachel was going to make her climax again, and was about to experience the triumph of having Tanya orgasm while she was deep inside her ass with a massive black strap-on dildo. On camera. Again.

No, no, no! Tanya thought, desperately trying to avoid what she knew was going to happen.

She looked at the camera, losing herself again in the wild waves of sensation that swamped her ability to think. Somewhere out there, men were probably gripping their own cocks, stroking away as a naked red-head dressed only in a tiny mask lost complete control of herself on their computer screens.

She could even see herself on the small viewport on the computer screen. Or at least, she could see some slut being pounded away on. Was that really her?

Then, the orgasm hit her.

It was like a tsunami, washing away all other concerns, and just leaving her a massive, wet, shivering mess of a woman. She heard Rachel laugh out loud, knowing that Tanya had climaxed again, and Tanya let out moan after ragged moan, as she began to squirt down her own legs again.

'Fuuuucccccckkkkkkk!" Tanya screamed, as she experienced the stinging humiliation of feeling such intense pleasure in such an embarrassing situation.

Rachel smiled warmly at Mitchell as he looked on, aghast, as the brunette mistress finished her final thrust with the strap-on into Tanya's ass. He looked almost as embarrassed as Tanya, having just seen his girlfriend pleasured anally by their arch-nemesis in a way that he had never done himself.

"Now," she said, with a wink and a smirk, "I know how turned on you must be right now, seeing your girlfriend experiencing the kind of orgasm that she'll probably never get from you, so the good news is that I won't keep you waiting for your next task."

She reached over to the table, where she'd previously left a note while everyone else had been distracted. Fiddling slightly with what seemed to be some cello tape, she then placed it on the small of Tanya's back, so that the note hung over her now very sore backside. Giving it a sharp tap, Rachel secured the note to the skin with the tape and then signaled for Mitchell to come over while she disengaged and finally turned off the camera on the laptop.

Eyes wide open, Mitchell walked slowly over to where his panting girlfriend quivered after the exertion of the poundings her pussy and ass had just received.

"You okay?" Mitchell asked, simply.

"Yeah," Tanya said, catching her breath, "I'll be okay."

Mitchell touched her back gently, and replied "I'm going to win the next task sweetheart, I'm not going to let you suffer the ultimate humiliation, you understand me?"

Tanya just shook her head. "Not going to happen."

Mitchell smiled with grim determination and then looked down at the note that would reveal his next task.

Any sense of resolute bravery lasted only as far as the first sentence though. As he read on to see what he would be required to do next, the blood drained from his face and he went a pale, ghostly white.

"Oh Mitchell," Rachel said with a smile, "I'm afraid your noble act of chivalry isn't going to be quite as easy as you probably imagined."

As Mitchell screwed his eyes shut, Rachel started her laugh again.
