You don't have to have really big tits.
It wouldn't be harmful or painful for her. It wont be so good as for you, f course, but I suppose it may be psyhologically big turn on for her.
Just don't cum on her face before you ask her.

You're rubbing something against her skin. I doubt that there's going to be much physical pleasure from that. But it might turn her on which prepares her for other things, so, well, I guess, win win?

I had my boyfriend try it on me one time. I don't like it but I wanted to do it since I knew he would enjoy it. In case she doesn't know already, have her push her boobs together for you.

it doesn't feel "good", necessarily. it pretty much feels like a dude rubbing his cock against your cleavage. there's not much else to it.
i would say do it, but make sure you do something for her afterward (ie. fingering, eating her out, etc.). that way she won't be all like, "uh, what about me?"

I wouldn't imagine they enjoy it greatly...

There is nothing particularly erogenous about the skin between the breasts.

Nipple stimulation and sucking would be much more effective.

Havent done it, ill let you know when i do, lol

its something thats always turned me on alot for some reason

I always thought the girls needed C cup + to do it tho

I personally love it. The feeling of his hardness between my tits (which are quite small, btw-yes, I definitely have to press them together against his cock) the feeling of him pulsating when he comes, and the warm feeling of him coming on my chest is awesome. I love watching him do it, too-so hot.

its not something that turns me on, but apparently it feels good for them so....
