Tavros has no idea how he looks. He feels awkward and nervous as much as he's turned on, but it comforts him to know Gamzee is still enjoying himself. Not that he isn't, he's just not used to doing something that makes it hard to think He worries about doing it properly for Gamzee, and he worries about making too much noise and they get caught. Distracting things, but not as distracting as that hand as the seconds ticked by.

The slight shift in position pulls a gasp from him as he can feel Gamzee press more firmly between his cheeks where he can actually feel things more substantially. Between that and the squeezing press of the other boy's hand he isn't going to last much longer, as evidenced by the way his breath is coming more erratically.

He holds on to the other boy tightly and buries his face against his chest to hide his moan, whimpering softly.
