That's the reaction she wants. He sways a little as she touches him but her hand on his hip steadies him, the other still working slow between his legs. It's working and she's glad, glad they've found a way to share this without it requiring him to change, and she gives him a rare and gentle smile as she presses a kiss to his thigh.

Her lips move against that skin slowly, trailing soft kisses and dragging her teeth against him to make him make more of those sounds, and she wonders just how attentive the humans have been with him. Have they touched him like this? Has he touched himself? Does he focus on giving pleasure rather than receiving to avoid humans reacting to the way his body was created?

The angle she's at, the fact that she's sitting on the bed and he's standing over her, it all makes the next step too obvious. There may be nothing there but it doesn't stop 2B from licking him, pressing her face between his thighs and rolling her tongue against that sensitive skin, so soft and warm and perfect, and she can't help the softly indulgent sound she makes as she sucks and licks at him.
