With frustration

Five days until the wedding:

Cassie returns from work and bends over to show you her plug. But both of you know that isn't what you're really interested in today.

"Yes, they're still in my pussy." Cassie says, anticipating your question.

"And...?"

"And what?" Cassie plays dumb.

"How was it??? How did you cope with the sensations?!" You blurt out. Regardless of whether this was truly your idea or not, you are **** to know what Cassie's experience has been like.

"You really want to know?" Cassie teases.

"Of course I want to know!" Your eyes are nearly bulging out of your head.

Cassie takes a couple more steps towards you and leans in to whisper in your ear. "I am so. Freaking. Horny."

You pop a near-instant boner.

"I can't stop thinking about my pussy. About sex. About wanting to orgasm. It's impossibly distracting and so devilishly teasing!" Cassie whimpers. "Any lesser mortal would have given up and masturbated after only half a day. But I love you so damn much, and I know how much this means to you, and I definitely couldn't just do it behind your back and then lie to you. So here I am, wet and ****, just like you wanted me to be."

With that, she saunters past you and up the stairs.

Why do I feel more turned on than I've ever felt in my life?

You pinch yourself, half to check if you're dreaming, and half to try and discourage the arousal coursing through your body.

This isn't right...

But regardless of whether it's right or wrong, that evening Cassie makes sure to get you to join her for her daily training. She prepares herself by inserting her vibrator vaginally and setting it to its lowest setting, as instructed. You bring up a specific video on the laptop.

Today's video is a video of a woman masturbating with a vibrator. She's lying on a comfy-looking bed with white covers. The whole thing is well-lit and produced. It's been done very tastefully, and clearly focused on her genuine pleasure. As per the rules, you masturbate freely while watching it, while Cassie has to just endure gentle stimulation that will make her feel even hornier but not have the slightest chance of bringing her to orgasm.

"Oh god, this is so hot, this is so unfair..." Cassie mutters to herself as her eyes flick back and forth between the porn she's supposed to be watching, and the thing she clearly is finding even hotter, which is the sight of you masturbating to it.

Despite your reservations you find the whole thing intensely erotic, and within a minute or two you're lost in a very novel and exciting masturbation session.

"Spread your legs." As you near orgasm you stand up and move in between Cassie's thighs.

"Yessssss..." You hiss as you spill your seed over Cassie's pussy and pubic hair.

As the haze of sexual bliss fades and is replaced by post-nut clarity, you look at your soon-to-be bride's jizz-matted pubes with a mixture of shame and distate. Your first instinct is to apologize. But then you notice... Cassie is breathing very, very heavily.

"That was so hot." She breathes.

Your fiancée is visibly more aroused than you've ever seen her before. It appears that your disgraceful actions and instructions have really awakened something in her. Either that, or those Ben Wa Balls have really done a number on her. The end result is the same - Cassie is currently a hot squirming mess. She lovingly toys with your cum as it soaks into her pubic hair.

"Please can I cum? Pleeeease?" She begs.

Yes! Yes! I would love to see you cum! I hate that you're not allowed to cum. It's so dumb and fucked up!

But the show must go on.

"I'm sorry Cassie, but this week is all about orgasm denial. If I let you cum, then it wouldn't really be such a difficult test now, would it?" You try to make yourself sound as reasonable as possible.

"I guess not." Cassie grumbles.

That night, you find that sleep comes easy - for you, at least. In the moments overnight that you do stir, it's because poor restless Cassie disturbs you with her endless tossing and turning, clearly unable to get completely comfortable.
