What if the droid is absolutely straight (phallus-like even in his posture), and she is writhing around him (leaning back into him)? One of her hands could be guiding his to the nipple which requires tweaking. Hmmm? Done this way, you could have her face turned up towards his. You might also consider short arcs from hand to hand or claw to nipple once you get body parts aligned. The first thing though is to make sure that these steel and plastic critters aren't going to fall over. They have mass, so they have to have balance. Carolly
