"Leave them on."
It shouldn't sting like it does. This was supposed to be a game, she's a queen and he's just a pawn (possibly a knight, two steps forward and one across). Something to corrupt - a little white in her black, if you'll pardon the metaphor.
You called this a relationship. But no matter how deep inside her he is, he still wants what she's not. So she takes him, glasses and schoolgirl uniform on. Bites her tongue. Doesn't look into his eyes when she comes, leaves in silence after he does. Plays to win, since she's already lost.
