Final round

Tanya hadn't teased you too much on that last minute of fucking and between the rounds as you were too far gone inside your head. Now, sucking on Sean's cock and cooling down, you were getting your senses back. Tanya noticed that and started teasing you and laughing, shooting things like

"Wow Princess, that cock looks like and ocean was poured on it! I guess you were really enjoying this! Bareback feels so much better than rubbers! And the implication of bareback is such a thrill!
"Damn boy, you leaking precum like a fire hydrant!! I guess you're really looking forward to filling up my little Princess's pussy with that potent cum!!"

But the one that really tilted you was

"Mmmmmmhh!! Nice and pulsing! Just how we like our cocks. Isn't that right Princess? That feeling when he could pop that gift any time soon!! Makes me wet! And apparently, it makes you wet too. This fucking thing is drenched in your juices! I bet you love it too so I'm gonna be a good girl and give you a nice gift: I'm gonna keep him right on the edge of cumming for you so you can enjoy that feeling from the moment you start riding him again! Your welcome my Princess!"

On that last one you froze for a couple seconds: you hadn't considered the other important part when your lust addled brain had popped out its flawed plan. Even if you could fight of your orgasm for the next round of fucking after cooling down, there was no way Dereck was getting a cooldown with Tanya keeping him on the edge of cumming. And there was no way he was lasting another 5 minutes inside you tight pussy.

You glanced at Tanya and she was softly licking and sucking and bobbing on Derecks cock. There was a delicateness to her slow blowjob, in contrast to the almost animalistic throat fucking she was doing earlier. She clearly knew what she was doing and, true to her words, she was keeping him right on the edge. Dereck's eyes were closed, his whole body looked stiff and he was sweating profusely. You actually felt a little bad for him: being edged for so long must be so tiring. Your eyes then went down to Tanya's and you each looked into each other's eyes while sucking on the cock in front of you.

Tanya was obviously enjoying herself and reveling in the slight fear that had showed in your eyes at that last comment. Her eyes had a devilish look and when Dereck twitched and moaned a bit more, indicating how close he was, you own fear increased and that devilish look only increased in intensity. She was reveling in the moment: her imminent victory on the next round of fucking, the realization of defeat and it's future consequences in your eyes, the ideas popping in her head about the next game the two of you would be playing, and how she would manipulate that game again to stack the odds against you, and then how she would do so even more by using that handicap you would obviously be getting from losing this round.

Dereck twitched and moaned once more and the intensity of her stare increased again, but you noticed something else: she was getting lost in the moment. She was enjoying herself so much, fantasizing away and reveling in the power she had over you and Dereck, she was getting so excited the intensity of her blowjob was slowly increasing. Every twitch and moan from Dereck, every fearful look you gave was just confirming her victory and sending her deeper and deeper into her fantasies and her head that she wasn't noticing how she was now heavily sucking on Dereck's cock, instead of carefully monitoring him, reading the sings, adjusting her intensity and speed and meticulously keeping him on the edge of orgasm as she had been doing at the beginning.

You noticed Tanya was now fueling her own fire and getting carried away by her own game and fantasies. Her eyes, still devilish, weren't reacting to you too much anymore. This was your chance to win: keep looking dejected, keep fueling her fire, and let her suck out Dereck's cum, making you win the round.

On Dereck's next moan, you perfectly timed a feign fear sound and look, pretending you were worried about him being on the edge and knowing he would cum inside your pussy in no time when you started riding him, while you actually knew he was on the way to cumming inside Tanya's out of control mouth. He was so close. You were so close to victory.
