It's the please that would send Jiang to his knees, if there were that kind of space. Instead, he kisses Proko filthily, then helps him sit up a little bit, so Jiang has room to fit down against the backseat and put his mouth to good use.

It's less clumsy than Proko, in part because he's not sucking dick over a gearshift. Also, because Jiang's done this a couple times outside of Henrietta, and he's learned what to do with a cock in his mouth. Proko is long and slim, gangly like all the rest of him, and Jiang strokes while he sucks at the head obscenely.
