Zeph looked up at her again as she bit his shoulder, though his skin seemed to have hardened in response, her teeth pressing against it uselessly as he growled, suddenly withdrawing his fingers from her slit and reaching up to grab her shoulder, forcefully pushing her back down on the ground as he moved to straddle her. The boy stared down at her, licking his lips as his cock twitched, then before her eyes it grew again, lengthening to about 10 inches and almost doubling in thickness while she watched, Zeph groaning in pleasure the entire time, his body already pleasuring itself from within.
Without any further hesitation, he shifted his body down, rubbing the tip of his cock against her slit, before thrusting into her roughly. "Ooooh! Y-yesss! Must...must....breed! Must impregnate!" He didn't know where the words came from, right now he didn't care...all Zeph knew for sure was that right now he had to fuck, he had to impregnate, he had to breed and it didn't matter who or what he did it with!
