anybody know yaoi manga with dry orgasm sex scene?

What's that?

well...umm....i dont know how to say it...

A 'dry orgasm' is what happens when a man reaches a sexual climax but does not ejaculate – so no fluid emerges from the penis.

It's an orgasm without semen coming out :P

yeah.....haha.....

there's on that's in one of the last chapters of punch up
