Something else you could do, without grabbing her breasts. Next time she is doing something at the counter, give yourself a quick rub to get hard (without her seeing of course!), then come up and give her a hug from behind, pressing your cock up against her ass. DON'T overdo it, she'll know whats pressing up against her and then she can make the next move if she wants to.
Hoping for an update OP !
