"Dave-- Dave, fuck, Dave--" He's knocked loose from practically gnawing on Dave's neck and thrusts down to meet each of Dave's movements, breathless and so motherfucking close. He doesn't want it to ever end, but at the same time he needs to release the pressure building up deep within him.

When Dave arches Gamzee nearly screams, raw, and completely overwhelmed by how good Dave feels-looks-tastes-sounds. A thrust later and he's shaking as an alien shriek is torn from him. He's not the wave anymore, swept away just as helpless to the flow as Dave is. Time feels like it's slowed to a standstill and Gamzee deliriously wonders if Dave is doing it somehow before his arms give out. He's able to twist a little so he's not completely crushing Dave but otherwise doesn't stop the slump, too strung out on the pleasure to do anything but breathe and make small awed noises.
