The other poll got me thinking. "Breast-only" means no other stimulation. Kissing I guess is ok. Rubbing, touching, or penetrating the vag means it no longer counts as breast-only. Touching anywhere else while stimulating the breasts is allowed. I had an ex-gf who could orgasm from only breast stimulation (me sucking on her tits in a certain way). I'm just wondering how common this is. None of my other gf's have been able to do this. And on a side note, one of my ex-gf's said she didn't really get any pleasure from breast stimulation at all. Pity. She had C cups, too.
