Gi'day. I'm one of those guys who starts to swell at the sight of a nice pair of breasts; especially bra-less, in a T-shirt. Either adding movement - the sway and jiggle in a loose fit or causing an apparent breast expansion - enlarging the breasts beyond the ribcage in a frontal view and enhancing the nipples with a tight T-shirt - amplifies the condition. I believe that most women are either unaware of this male response - or disinterested. This is also posted on measurerection. Comments ?
