Well you gotta think of how they'd realistically react:
~Would obviously decline your advances and think of you as a creep although there's nothing to really grab
~You could probably get away with her....she's not the brightest and seems naive but it's still wrong and she'd still likely look uncomfortable
~Would end you before you could fully lay a hand on her, remember the NG3 massage scene where the men tried to take advantage of her in only a towel?
~Definitely would resist, Kasumi's not like that
~Wouldn't accept, she's supposed to be a lady, not a pass around
~Like Kasumi. She's a shrine maiden, she's not gonna let you touch her, she'd break your arm
~ Would probably let you feel her up but she's the most shamelessly sexual DOA X3 girl so that's to be expected
~ Same as the other non ninja girls, she not gonna let you grope her
TN doesn't want their girls being easy and coming off as sluts, so TN intentionally makes them react that way in the VR, even in the photoshoot mode they'll look physically uncomfortable and upset in the more perverted and sexual poses which albeit disturbing is a good way to steer players away from that, and if they do well their girl is gonna be pissed with them....lol
