"Fuck!" Rat arches off the bed and grabs the back of Marius' head, fingers knotting in his hair. When Marius bites him, when his fingers quirk just slightly up, Rat feels it. The pressure peaks, shudders through him, and he's panting and thrusting his hips forward instinctively.

It feels as though an age has past when Rat falls back into the mattress, even though it can't have been more than a minute. His body shudders with aftershocks, of a truly overwhelming sensation, and he stares at Marius, eyes wide.

"That..." He doesn't have a word for it, not really.
