A challenging day at work

Four days until the wedding:

Today is your final day both in work before your annual leave for the wedding begins. Both of you being at the restaurant together means you get to see first-hand what Cassie looks like from a bystander's perspective. She looks... well, to you, she looks like someone who desperately needs to orgasm and is being kept constantly lightly stimulated by a pair of Ben Wa Balls. But to others, she probably looks slightly unwell, or overheated. But, overheated doesn't really make sense considering that she is wearing a skirt with bare legs, and a light blouse.

Can she really go all day like this? Most of her shift will be floor management duties, which is a lot of being on your feet and moving around. Could she get caught? Even worse, could she go insane?

You should not be enjoying this, but the sight of your secretly sexually supercharged soon-to-be bride struggling through hour after painstaking hour of subtle stimulation is impossible to not find arousing. Every heavy breath, every slight falter in her step, the slight strain that can be heard in her voice as she tries to pretend everything is normal... You can't handle it. It's so damn sexy.

For the second time in a few months, Cassie finds you forcing your way into the cramped toilet cubicle alongside her when she tries to go to the toilet. You don't say a word - You just grab her waist and shove your tongue down her throat. She immediately accepts your intrusion, and it's all she can do not to moan too loudly as she melts into your arms.

God, she really is ****, isn't she?

Even with all the perversions of recent weeks, you don't think Cassie would be so receptive to advances in the restaurant bathroom if it wasn't for her current heightened state of sexual arousal and prolonged denial. It's not just the one-and-a-half days she's been wearing the balls, after all - she hasn't orgasmed since we started this whole "Anal Only" thing back over a month ago.

Within moments she's grinding against your thigh like a bitch in heat. As she's only allowed to wear skirts and those fetish panties now, once she gets her skirt hiked up there's only a thin layer of fabric separating her clit from your rough jeans, and she's able to work herself up and up, closer and closer to that peak she's so **** for.

I shouldn't have come in here.

There's nothing you want more in the world than to let her cum. But you can't. Whilst you're sure that the blackmailers aren't watching you right now, there's no way for you to prevent Cassie from talking about her orgasm later, at home, where they can hear you. No, she has to stay denied this week. It's for her own good.

You begin to pull away, but Cassie tries to take control. She reaches down to massage your junk and whispers seductively in your ear.

"Please... please... I want it inside me so bad. Come on, just once..." You can hear the raw desire in her voice and in this small confined space you can even smell her arousal.

"Those aren't the rules." You mutter, somewhat sadly. "If you don't want to break the rules, then I can't. Sorry."

You let yourelf out of the toilet before she can try to convince you any further.

I'm so sorry, Cassie.

It takes a good fifteen minutes for Cassie to leave that cubicle. You know she's too honest a woman to have gotten herself off without telling you, which probably means that what she was doing for the last quarter of an hour was desperately trying to think about anything other than sex in an attempt to cool off before rejoining the floor.

Later, once you are alone in the car, Cassie speaks up.

"That was cruel, you teasing me in the bathroom like that."

"I know, I regretted it immediately. I'm sorry. Can you forgive me?" You reply remorsefully.

"You misunderstand." Cassie says quietly.

"What?"

"This game... this teasing thing... I've never been so horny. So obsessed with you... with the idea of sex. Yes it's frustrating, and even uncomfortable at times... but oh my god John, seeing this side of you, how you can turn me to putty by dominating me like this... It gives me such a warm fuzzy feeling inside. I'm having so much naughty fun... I'm really enjoying this challenge."

She smiles shyly at you.

I must be dreaming. This can't be reality.

You still seem to be awake and not dreaming when the evening rolls around and it's time for your new daily joint porn sessions. Today's video is again focused on women's pleasure, but it's much more intense. Instead of a single woman masturbating, it's a fast-paced compilation video of women being **** to orgasm with high-powered vibrators that leave them squirting like fire hydrants and losing control of their shuddering, flailing bodies.

And meanwhile, what is Cassie experiencing? A vibrator set to its minimum strength, while her fiancé jerks himself off to his heart's content right next to her. After two days of constant teasing, this is surely enough to drive any normal woman round the bend.

But not your girl. While she's clearly **** for release, she's also committed and focused. Her eyes barely leave the screen as the images and sounds of mind-crushing orgasms blast away in her face, one after another after another. When this woman puts her mind to something, her dedication is unreal.

This whole situation is too hot for you. Plus, the porn video is genuinely very exciting. Once again it's an embarrassingly short amount of time before you're once again at your limit. Today, your instruction for where to ejaculate has become even more lewd.

"Give me the vibrator." You suddenly instruct.

She obeys unthinkingly, and just in time, too. You bring the toy down to your crotch and coat it in your cum. Lots drips off to the ground, but lots more remains on the gently vibrating toy.

"Now put it back in for the remainder of the video."

Cassie whimpers and obeys.

It's a long video.

Of course, it does eventually end. But it took so long that your petit mort is over and your member is already stirring again. You even have enough arousal to give Cassie her final instruction without too much difficulty.

"Clean it with your mouth."

Cassie, for her part, is way too far gone to even consider the novelty and grossness of the task you've given her. It might be her first time ever properly tasting her own pussy juices, but she does it without hesitation and without complaint. She looks a bit... zoned out.

"Are you okay?" You can't help but ask after she's finished swallowing down the small but potent boy-cum and girl-cum cocktail.

She flashes you a wide grin, and her eyes also go wide, making her look half-crazed.

"Too much sex and no orgasm makes Cassie's brain go bye-bye." She jokes.

Hopefully it's still just a joke by the end of the week.
