The sports bra

"I guess the sports bra?" Vanessa says "But what makes it special?"

"Oh I can't give that away yet, it's a surprise but I promise you'll love it!" The man says a bit excitedly. "Follow me and I'll show you."

The man leads Vanessa to a private room, one with a single chair in the middle and some equipment on the wall. He hands her the bra. It's way too small, and there's no way it would fit on her. She looks at him in confusion.

"I can't wear this." Vanessa says

"Sure you can, try it on." The man says

"One, it won't fit, two I'm not taking my bra off in front of you" Vanessa explains.

"Oh I can look away if you'd prefer" the man says turning around. "Trust me though, you want to put it on!"

Vanessa thinks about, but imagines it couldn't hurt too much. So she takes off her shirt which cause her breasts to flop out, then she takes her normal bra off, her breasts being left free, though they don't sag, they've always been incredibly perky, something Vanessa hated. She struggles to put the sports bra on, but she manages to clip it, though it's not even covering her nipples, and it's pressing against her chest so tightly Vanessa thinks it might snap. Then suddenly the man turns around.

"Ah I see you've got it on, wonderful!" The man says, making Vanessa try to cover up, though to no avail. "Calm down miss, just have a seat and watch the magic happen."

Vanessa sits down in the chair, not moving her upper body in an attempt to try and stop the bra from snapping. Then the man pulls out a remote and presses a button. Suddenly, the bra expands, covering Vanessa's entire chest. It's perfectly her size, and her breasts feel fully supported, and not squished at all. Thanks to the design, even though it's still obvious how large her breasts are, they don't have any cleavage.

"Oh oh my God." Vanessa says, standing up. "This is incredible, how did you do this?"

"He he, a good inventor doesn't give out his blueprints, though I'm glad you like it." The man says, clearly pleased with himself "That's not all it can do, jump, bounce, run around."

Vanessa follows these instructions, and much to her surprise and joy, her breasts barely bounce, so she's able to move more freely than ever before! A large smile washes over her face, and she runs over to hug the man and thank him a thousand times over, telling him he's a hero and this will help her and so many others.

But then, almost like a switch flipped, he pulls Vanessa off of him and tells her

"Now Miss, I could get in a lot of trouble for giving you something like this this early. It's very new, so it's very expensive, we haven't figured out how to keep costs down, but if you want to keep it, I can give it to you for a price."

Vanessa panics a little, she doesn't have enough money to pay for something like this, and yet she also doesn't think she could go without a bra like this.

"I don't have any money, but I'll do anything you want to keep this, anything!" Vanessa begs.

"Anything?" The man says, sinister grin creeping across his face. "Well you could give me a blow job, but for something like this I think I'd need something more. Installments. A blowjob today, a titjob tomorrow, and then you let me blow your back out."

"Wh-what?" Vanessa sputters, completely in shock by the request. Initially her first thought is to refuse, but she doesn't know if she could go without this comfort. She could even try to steal it, but that would be difficult with only one exit.
