Mostly...

As the two emerge they find one human crouched behind a box shaking. They stare straight ahead and they're teeth chatter. They don't seem to notice Biters boner which is an inch away from the side of their face. A familiar scent begins to wafts up towards Big boy's nose now that the scent of burnt skin and gun powder has settled down. His cock begins to rise and he notices Biter's head is now dripping. They seize the girl who suddenly snaps back to reality and begins to kick and scream. They tear the armor from her breast and lift her into the air. Her b-cups stand out from her chest, capped with tiny little nipples hard enough to cut glass.

Big boy hoists her into the air as biter uses his teeth to tear the wet fabric away from her crotch. He buries his face in her folds and begins to nibble on her clit. It isn't long until the girls panic turns to pleasure. She shakes her closely cropped head back and forth as she shrieks with pleasure. Soon enough biter is standing upright and Big boy drops the girl onto his cock. She leans her back against big boy, using his erection to support her ass, as Biter fucks up and into her. Biter doesn't last long, this being his first time, and soon his seed is leaking out of her cunt. Big boy lifts her off of him and has a go at her hole for awhile. He's much longer and the girl gasps as she feels him sink even deeper into her folds. She passes out and big boy has to hold her limp body against his chest to keep her from falling off his prick. When he's done with her he lets her fall to the floor. The two mutants look at each other and Big boy claps his brother on the back to congratulate him. Biter picks the girl up and throws her over his shoulder and the two of them head back towards the lab to collect Evelyn and her cuck intern.
