Valjean's hips snapped forward, dragging along the spot that made Javert melt with a groan into the surface beneath. Nails scraped his back as he hit his target a second time and whimpers assaulted his senses as he picked up speed.
"Boop… Boop!"
Javert, although half-delirious with pleasure, had not lost the ability to stare at the other man incredulously. Valjean smiled, and thrust forward again, delighting in the way Javert's eyes rolled into the back of his head.
"Boop … Boop!"
"Jean, what the hell are you —" He was cut off by his own strangled gasp.
"Boop!" Another hit of Javert's prostate.
"Boop! … Boop! … BOOP!, BOOP! … BOO - ah, Javert!"
Later, when they lay tangled in the sheets, Javert did not mention Valjean's odd goal or proclamations, merely poked him on the nose with a muttered "Boop."
