Give the belt's oral stimulation a try.

"I want to try something," you fill in Emily. "The program said I'll get some stimulation when I'm giving head. I'd like to see how that works, you know, before I end up trying it with a guy I don't know." You feel like you're already giving in to the belt's control over you. You know the real reason is that you want to start building up your chance for your own orgasm and you know that your roommate is easy enough to satisfy.

"Well, if you want to try it out on me, I can't say no to that." Emily practically licks her lips as you bet she is already imagining you between her legs. Quickly, she's stripped off her clothes and is straddling your face while you lie on your bed.

Emily hovers her pussy just a bit above your face, leaving you to reach up for it with your tongue. You easily find her slit and run the tip along until it reaches her clit. From this position, you get to see her cock her head back in pleasure. Your belt quickly picks up on your actions and you feel the vibration begin against your clit. It's strong enough to distract you for a few seconds and you back away from the delicate lips in front of you. The vibrations stop just as quickly as they started, signaling you to get your tongue back in there.

With your tongue fully gliding against Emily's slit, the vibrations return in full **** and you try your best to keep them active this time. Your constant **** on her clit causes your roommate to cry out in pleasure and creep down further onto your face. Each time she lowers herself, it gets easier for you to get even deeper with your tongue, and you're practically grinding into the chastity belt, trying to get all the stimulation you can. You can tell you're slowly building up to your own climax.

Now, with Emily suffocating you with her pussy, you are able to apply some pressure by pulling her clit directly into her mouth. As you do, she starts grinding against your face, completely ignoring you and using your face for her own pleasure. You can't say you're not doing the same, now. Your muffled moans vibrate Emily's nethers as you ride the vibrations to an ever-approaching orgasm. You can tell your roommate is close when she suddenly gets even wetter against your mouth. She shrieks as her pussy convulses against your tongue, her orgasm completely overtaking her. You grab her ass with your hands and keep her in as you are getting close too.

Emily's orgasm settles down, and she tries to pull off of your face, but you keep pulling her down. You _need _that orgasm. Too bad for you, it never comes. The vibrations stop abruptly just moments before you climax. You sob with need into Emily's now sensitive pussy. She can't take anymore and slaps your hands off of her and sits up off your face.

"Fuck fuck fuck!" You yell out, reeling from that edge.

"Shit, Lauren. You nearly overdid it!" Emily complains.

"I'm sorry," you pant out. "It's like something switched in me and I just had to cum."

"It's okay. That much lust can make you do crazy things. Please just be careful out there."

Emily fulfills her promise of heading out for her class, it's not quite as early this time, but it didn't take much time for you to get her off. Now that you're alone, you check the app on your phone and read the line "Current chance of orgasm: 1%" Okay, at least it seems to add 1% instead of multiplying by it, that's one load off your mind. You think for a moment, you could go out and find some lucky guy to drain right now and have a chance at cumming, and at worst, you would double your chances for next time.

You shake your head and try to forget going out right now. Your next concern needs to be the hour of teasing. With Emily gone, this will probably be your only chance to get it out of the way for today. You're worried, though. The level 2 stimulation was brutal enough and that took maybe 10 minutes to edge you. You don't know how harsh level 4 will be, but you think you'll have to be prepared for at least a dozen edges over the next hour, maybe more, considering how close you still are. You check your phone again to confirm, right now it lists your arousal level at 5. Wasn't it at 2 before?

You also consider Velvet's idea. Do you really think you'd fare better against an hour of painful punishment shocks tomorrow?
