Offer to 'help' her.

"I can help you get through this." You raise your chin, looking very confident. This is not lost on Heather, who you could swear seems even more attracted to you now.

"Really," she asks, her face breaking into a smile. Despite how badly she wants you right now, she can't help but be excited by a renewed hope of surviving this ordeal.

"Wouldn't be the first time. Of course...I wouldn't mind a little something in return."

She coyly looks through her pockets, knowing exactly what you have in mind but playing along. "All I've got is the money I was gonna use to get home. That subway was awful, but at least the ride was free. Unless..." She approaches you, her teenage breasts pressing against you and her face so close to yours. Her breath smells sugary-sweet, yet also kind of medicine-y, somewhere between cough syrup and some kind of juice. You wonder if that's what health drinks taste like. "...the only other thing I've got that you might like is..." She bites her lip and takes your hand, placing it on her hip. You look down at it, then back at Heather, finding her looking back at you with a raised eyebrow.
