Pretend to be one of the costumed models.

Supergirl tips her head to the side and does her best to look confused "Uh.. huh? Her? I'm not sure what you're talking about, but like, Rex... he's my boss you know, keeps telling me I'll be like a suuuperstar if I... oooh, her her? No, I'm not Supergirl" throwing on a little giggling at the end to really sell it 'Rao, unless I piled on too much he'll believe me for sure, and probably think I'm a bit of an airhead too, which I'm sure he'll be happy to exploit'

"Anyway... like I said, Rex said I'd be a star for sure if I had a bit more to show off with here" she says, shaking her upper chest, not that there's much shaking.

Raising an eyebrow the man nods "Yeah, I can see you need quite a bit of help there, I'm the keeper for this facility and I do remember there was a large order tonight, follow me and we'll have a look see in the office" grinning at the blonde girl he reaches an arm around her and starts guiding her, slowly, towards the other side of the room, his hand placed so low that pretty much all of it is planted on her ass.

And as for your pregnancy question; no, of course not, those are in our long term fetish program or in our fertility program, sometimes both, though some of our more boob-centric programs do induce lactation, at least for a while."

'Hmm, from the sound of his heart it seems like he's mostly telling the truth, just a bit of an off sound after mentioning the lactation, though I guess he might just really be into that. Time to convince him I'm an easy target'
Smiling up at the keeper Supergirl nods slowly "oooh, well, I haven't lactationed my nails in far too long, so that's ok... but I don't want no baby in me until I got a ring on my finger so I'll stay away from those programs for sure."

Arriving at a desk on a slightly raised platform, the keeper lets go of Supergirls ass and starts checking the schedule "Your nails... oh you'll fit right in here with hardly a change. Ok then, let's see what you've been signed up for, hmm. I see Rex Modelling has bought 8 next-day full size boob jobs, and..."
