In everyday life, even if I happen to meet a girl wearing a low-cut top showing off her cleavage, or a girl without a bra, with her nipples erect through her clothes, I can't really look directly at them. "I really want to see it up close, I want to stare at it carefully, not just take a peek..." The girl's expression seems to have changed to something naughty, as she shows me her erect nipples without a bra.
