Carissa can help you test a theory

Carissa returns with a mocha for you. She glances over her shoulder and places the steaming mug on the table in front of you without a word.

"Thanks a lot Carissa, listen I got another question for you."

"You know actually sir I'm not sure how I feel about that last question."

"Would you rather think of me now and always as a nice guy who never does wrong, or grow your tits one cup larger?"

The cute waitress scowls at you, and it won't be the last time either, you think to yourself as you watch her large bust grow enough to where it barely makes any sense any more. After she answers you, she's still got some of that scowl on her face, but her frown lines are replaced with curious wrinkles as she runs a test of her own. She rocks back on her heels, forward on the balls of her feet, and back again, coaxing from her chest some of the greatest bouncing you've ever seen in your life.

"Okay so I thought you were just some weird perv but you're actually a magical perv?" She gets it. And now it's time for the test.

You nod, guilty as charged. "Yeah and you're helping me with my magic, so thanks. Check this out, you look great by the way, but I have another question for you." You harbor no protest. "Would you rather...." you should say this one carefully "...think of me now and always as a nice guy who never does wrong, or grow your tits one cup larger?"

She blinks a few times. "Wait you already asked me that?" She's not thrilled.

That's not an answer. Uh oh. You frantically grab at your own chest, but it's no bigger. Does that mean, no, you're acutely aware you're no saint or even gentleman. So did it backfire?

But then she answers you, and her tits grow again, way too big for her slender frame. So it seems like it just took her a moment to decide, as upset as she was at the prospect. Still, most people so far have answered you directly, with what you would often consider far more difficult or unpleasant choices. Mostly, though, this just means there's one last phase to the test.

Carissa is still a little too preoccupied with her new burdensome bust to flee or cover her ears, so you lay it on her: "So Carissa, I was just wondering, would you rather think of me as one of the greatest people ever, or grow your tits two cups larger?"

You sip your mocha and jizz down Erica's throat. You reach under the table and pull her head against you to tell her you're not done yet, and she continues to blow you.

Carissa tears up and sniffles. "It's just a very mean line of questions to have come from such a, such a nice," her crying is short lived, and she warms to the idea, apparently very pleased she didn't choose further back problems, "well such a wonderful guy really! I mean, these boobs are toooo big by at least a little bit, but hey, thank you so much mister."

"Sure thing Carissa."

"Like, you really are one of the greatest." It must be awful with her massive tits crammed up into that bra, but her smile is rays of sunshine beaming down on you.

You pull out of Erica's mouth and spray her face with all the cum you can muster.
