Rhea'li's grip around his own cock tightens at Crowley's imprecations, blood rushing south. Hearing the chatty demon's vocabulary degenerate from sentences into single word outbursts spurs Rhea'li on, taking as much of Crowley's burgeoning dicks into his mouth as he can, tail flicking as he feels Crowley tug at his hair.

...But he has no intention of putting out his jaw from this, so he reluctantly lifts his mouth off the hemipenes -- although not without the flat of his tongue licking up along their underside -- before going down again on just one, letting his cheek rub against the other. He still has one free hand, however, and he's never one to have idle fingers. So Rhea'li slips them into Crowley's slit, listening for Crowley's reaction when he strokes him inside.
