H-how can I cum without ... ?

You have to think long and hard about her "offer" ... or rather, FAST and hard, before Cassie decides to withdraw the offer entirely. After your shameful display of begging (your face reddens at the memory), it's now obvious who's holding the reins in this relationship, and she's starting to tap her toes impatiently.

You asked for this, after all, and she's right; of all the things you could have requested of her, it was this you wanted: to give her control of your sex, to let her decide when you could orgasm. And it was YOU who was talking about weeks-long or even permanent chastity. Even through the haze of your lust, you're ashamed of your performance. Twelve days?! Twelve days is nothing.

On the other hand, twelve days seems to be all you can stand, first time outta the box. You ARE a healthy, young male, after all. But ...

"Please, I need to cum so bad ..."

Cassie arches one eyebrow, a frown marring her beautiful features. "Wrong, slut."

You blanch as you realize what she means. She doesn't want you to call yourself ... that ... all the time, does she? But you're so goddamned horny, you blurt it out anyway.

"S-sorry. This slut really, really needs to ... to cum. B-but how can I do that if y-you don't ...?"

She's still frowning at you when she answers. "Better. But from now on, you will refer to yourself as 'this slut' WHENEVER you request a sexual favor from me ... if you want any chance of getting it granted."

You hang your head, partly in shame but mostly in confusion. When had your girlfriend become so dominant? She'd always been so laid back and easygoing before this started ...

She lifts your chin, her eyes concerned but her lips smiling again. She kisses you, nibbling your lower lip for just a second. "Hey, don't worry, baby. I have to be hard with you to get you where you want to be. You still want to be here, doing this, don't you?"

You nod, returning her smile, which immediately widens. "Good boy. And don't you worry about how how. You remember when I said I'd do anything for you? That's because I've done ... a lot. Probably more than you want to imagine. Trust me, I know how to make a man cum. Now, drop those jeans and panties."

You flinch inwardly at her categorizing your boxer-briefs as "panties," but you're so **** right now that you do your best to ignore it, kicking off your sneakers, hurriedly pulling off your socks and then stripping your jeans and underwear down your legs simultaneously. Cassie, still smiling, takes hold of your chastity cage and tugs gently. "This way, Chasty," she giggles, leading you toward the bedroom.

She leads you to the bed by your cage, an action whose symbolic value you cannot miss even in your current state, and sits you down, then strips off your shirt, running her hands over your torso again, and kissing you until the tee gets in her way, sucking your tongue into her mouth.

"Now, lie down on your side, and face that way," she orders, pointing at the far wall. After you do, you hear her opening one of her dresser drawers and rummaging through it.

"Do you remember how we spent almost three months doing anal at least two or three times a week?" she asks, still audibly digging.

Confused by the question, you answer in the affirmative, wondering what she's getting at.

She approaches the bed again, leaning against you. You can hear her fumbling with something, maybe a cardboard box. "And do you know how many times I came, getting railed in the ass?"

You have no idea; she always seemed to enjoy it, and she ... expressed climactic excitement ... quite often, but you really don't know. Embarrassed, you tell her you hope she came that way fairly often.

She kisses the side of your jaw. "Every. Single. Time," she says, "Did you reach around and touch my clitty every single time?"

Face reddening again, you apologize and admit that you had not. Cassie immediately places her fingers across your lips and shushes you. "It's okay, baby. I told you I came every time, didn't I? I didn't need you touching my clit to cum, and I don't even have a prostate to ... excite.

"I can cum without touching my clitty," she says, reaching over your shoulder to show you the big, pink latex dildo in her hand, "and so can ... so WILL ... you."
