Play it cool. Apologize.

"I should be the one begging for forgiveness," you say. "I had this weird feeling you needed help... but I never expected to see this... when did this happen?"

Shannon looks up at you with panicked confusion. "I-I don't know. I just woke up like this. I haven't slept in all year and now this..."

-She seems a little less on edge, apparently, she appreciated your concern, Not to mention it was a pretty nice act.-

You approach her slowly. Not only are you getting a nice look at her massive tits, but the rest of her body as well. Shannon is in pretty nice shape, with a nice tight stomach and since she's only in panties, you get a nice view of her hips and butt too.

"Are you saying someone did this to you?"

"Yes. I mean... I guess. I wasn't like this last night. Someone... well... gave me giant breast implants!"

"That's crazy!" you say. Though you have a good idea how it came to be. "Are you alright?"

"I think so... I mean, they feel O.K. outside of being pretty sensitive." She moves her hand a little, giving you a better look at her giant pink areola. There's no easy way to say it, but she looks like a porn star now. Her tits are so big and overstuffed, they hardly jiggle when she moves. It's pretty hard to resist touching them. "Oh, god. What if I signed some sort of contract. What if I need to PAY for these things? Worse, I'm gonna get expelled over this."

She has a good point. You're holding all the cards in this situation.
