Try to wake Tommy up.

"Tommy. Tommy." Billy whisper-shouts. Tommy continues to stroke himself, taking a small step closer to Billy, who leans forward so that Tommy can hear him better. "To--MMH!"

Tommy shoves his cock into Billy's open mouth. His full length is in Billy's mouth in a matter of seconds. Tommy tilts his head and drowsily moans like a wildebeest at the pleasure. He grinds his hips against Billy's face, pushing his cock down Billy's throat, stretching his windpipe.

Billy gags, holding Tommy's ass for support as Tommy fully skull-fucks him.

Billy feels Tommy's balls slapping his chin and, despite himself, gets hard.

Tommy picks up speed, becoming a blur of motion as he uses his twin brother's face like a fleshlight.

Tommy is finally woken up by his own orgasm. He cums, pounding his jizz into Billy's esophagus. Billy swallows automatically.

Tommy collapses next to Billy, looking at him breathlessly.

"Well, shit," Tommy says.
