You're a 20-something male riding the subway on a Saturday afternoon. The train isn't packed, but it is busy enough that you're standing holding on to one of the overhead railings rather than sitting. As you glance around at the strangers on the train with you, one standing nearby catches your eye. She's about a head shorter than you, a redhead about your age and quite attractive. In particular, she's got what seems to be the best set of breasts you've ever seen in your life. You guess they are size D and all natural. The woman is wearing a low-cut shirt and apparently no bra as her breasts are pert and perfect on their own. You notice she has something tattooed just above her ample bosoms, but you can't read it from where you're standing.
Then you realize she's looking back at you. It's not an inviting look - more like a glare. You guiltily look away, but she takes several steps to bring herself next to you.
"It's not polite to stare" she says flatly.
"Sorry" you mumble.
"Don't stare unless you want a pair" she warns.
You look at her face, which seems quite serious. You nod sheepishly and mumble another apology. You stand next to each other, watching the tunnel lights pass in the windows of the train. You force yourself not to look down at her chest. The train slows as the next stop is announced. When the doors open she moves toward the door, but turns briefly toward you with a strange look on her face. She's close enough that you can read the tattoo script above her breasts. The tattoo is the same warning she gave you verbally: 'Don't stare unless you want a pair.' The woman steps through the doors onto the platform. You have an instant to decide whether to follow her. What do you do?
