He's waiting for Barry to come, eager for the taste of it, and he isn't disappointed. He groans when Barry shoots across his tongue, swallowing hungrily while staring up at him. He keeps sucking until Barry pulls free, and he lets out a regretful little whine until Barry is suddenly right in front of him. He doesn't even realize that he's trembling until Barry pulls him in close, and he tumbles into his arms and lets out a muffled moan against Barry's mouth.

"Barry," he breathes out, opening his mouth wide as Barry licks his way inside to taste himself. His own cock is so hard that it aches, and he resists the urge to reach down and touch himself. He leaves that for Barry, because his is the only touch Derek wants right now, even above his own.
