Her smile is more electrifying to him than if she'd suddenly run a direct current into him with a live wire. He feels himself choking up at the sight, practically blindsided as she steadies and keeps him in place. It's a good thing she does, for his knees feel weak and wobbly as she pays him such care and attention. The sounds she makes are erotic in a way that get to him more than any human sounds have thus far. It's because they're from her, of course, and he has an extreme bias, but that doesn't detract from the effect they have on his pulse or internal temperature rising.

For the most part his partners haven't exactly been attentive, but that wasn't exactly a fault of their own. He shied away from being given attention down there, for fear of being rejected. Besides, he much preferred being useful and giving pleasure, rather than receiving it.

But that doesn't mean it doesn't feel good. 2B sure does make it feel good and somehow they've managed to avoid hurting one another. (So far, at least.) He mutters out her name, the number and letter spoken on a sigh that seems to fall out of him, fingers gripping her hair just a bit. His toes are tingling, wriggling in his socks, trickles of electricity shooting down his spine. It's a lot of sensory information she's unloading on him right now but he's enjoying every second of it.

"2-2B...oh man-"
