Skip the foreplay. How about your place for sex?

You gesture behind you. "You don't really want to be here anyway, right? How about you come to my place and I can help you unwind."

"You're asking me to go home with you? What did you have in mind?"

"Sex, mostly. But I had plans to play with those titties of yours all night while doing it."

Sadie looks at you with a curious combination of appall and curiosity. "Did you seriously just say that?"

"I did. You randomly grew giant breasts, aren't you eager to give them a test run?"

"Look. I get why you're excited about this... but I'm still not sure I'm OK with it. I mean, yeah, I'll admit I'm happy about it. Mostly. But I don't know you, and I'm not so **** that I'm gonna fuck some random guy."

"Well, I'm not exactly random." The words slip out of your mouth without you thinking.

"What do you mean by that?"

You're overcome with a sense of invulnerability. Maybe it's the brashness you've shown with the notebook, or maybe it's just your dick talking. "I'm the one that made you bigger."

She gapes at you. "You... you haven't even known me for an hour..."

You shrug. "It's complicated. Look. If you want proof, I can prove it-- but that would involve making you even bigger."

Strange thoughts race through your head. What if her size isn't the only thing I can influence? Maybe I could change her countenance.

"B-bigger? I'm huge. At least a Triple D or..."

"Way more than that," you say. "Just to make it simple, why not just keep it to single letters. You're at least three sizes past that."

"You're weirding me out..."

"Are you mad? You just said it... you like being this big. What's another size or two-- or six."

Sadie winces at your words. "That sounds... terrifying and interesting all at once."

You point down at your cock. "What if I told you sucking it would make you grow? I'll leave it up to you how much, all you have to do is swallow once for one more size. Two for two... three for three..."

Sadie chuckled. "You're using this as an excuse for me to give you head? Try again."

"Your tits randomly grew. Overnight. How strange are my words?"

Sadie gives you a puzzled look. "Good point. I'm gonna be mad if it doesn't work."

"Because you want bigger tits? Or because you're afraid you're wasting your time?"

"A bit of column A. A bit of column B."

You unbuckle your pants. You can always write the note while she works-- while she's distracted.

Sadie inches closer, silently agreeing to your terms. "I uh... haven't done this before."

You smirk. "It's fine. Awkwardness is pretty sexy in its own way."

Sadie slips her hand down the front of your boxers, pulling your cock out. From your estimate she's handled one before-- she just hasn't put it in her mouth. Go figure. Life is full of firsts.

While she strokes you, you casually pull out a scrap of the Notebook, and scribble. _Sadie, breasts grow a size every time she swallows cum. _In the tiny bit of space next to the text, a J Natural appears and the whole sentence turns red. You crumple the scrap into a ball before she can notice.

_Here goes nothing. _She spends a good amount of time stroking you before kissing the tip of your cock. She's adorably hesitant and that gets you in the mood pretty fast. By they time she laps at you with her tongue, you're rock hard and ready.

You close your eyes and remind yourself cumming meant inflating her tits, and that willful reminder makes you want to cum fast and hard.

"Since you doubt me..." you say. "I won't leave you waiting."

"I guess I'm a natural, huh?"

You palm the back of her head and push her down on your cock slow and deliberate. There's a pleasing 'gluk' sound as you touch the back of her throat. That makes you lose it. You throb and pump a generous squirt right into her throat.

"Just swallow. You'll be glad you did."

She taps you on the hip, seeking reprieve. You give it to her when you feel her throat tighten on your cock. Down the hatch it goes...

Sadie pulls away, gasping and sputtering. "Gah! You could have went a little slow--" her hands moved to her chest, her tits quiver gently, and past the collar of the T-shirt her ample cleavage bobbles in a hypnotic fashion. A low gurgle comes from her, almost like a stomach growl, but you know better.

She gasps, assaulted by some unseen pleasure and moves her hands away, arching her back. Her breasts squirm and fatten, as if shaken from the inside.

It worked.

You stare down it awe. It's a thousand times better when she knows it's happening and the idea of it makes you want to fill them more. You blindside her, stuffing your cock back in her mouth. She moans against it, widening her mouth more. She wants it.

You focus on one thing and one thing only. Semen. You give her another blast and she swallows it greedily. You worded the note sloppily and she grew with each swallow. You need restraint. You pull away, making a nice little pop noise from her greedy sucking, strands of cum dribble from her lips.

You pull out her shirt at the collar, stretching it out a bit. This time you plan to see every second.

Sadie, lost in her a drunken daze, savors the sensation. The gurgling resumes, filling her already swollen bosom more. You get a nice little peek at her huge areola from above, and her thick erect nipples.

You feel amazing. You feel powerful. Everything is going according to plan.

Her breasts swell and fatten into the shirt, you practically need to tear it to keep a good view of her tits. When the settle to a stop you realize, you're going to have a hell of a time sneaking her out of there without people noticing.

Shit.
