Bob's knees are already starting to ache, the back of his throat tight as he breathes carefully through his nose and slicks down an inch, two. Brian makes a low, appreciative noise, his fingers snagging in a knot in Bob's hair.

Bob won't even need ten whole minutes; he can do this in five flat. A year's worth of quickies in Bob's classroom and Brian's office (and the janitor's closet, that one time) has taught him a thing or two about the whens and wheres and hows of making Brian come hard and fast. Bob backs off a bit, runs his tongue under and along the crown of Brian's dick. Brian's hips jerk reflexively, and Bob grins, glancing up at Brian's face.
