As the spit-roast raged on, Sweetie was the first to cum. She moaned through the slab of meat inside her as her whole body began to convulse. The hardest orgasm of her life, she could feel herself becoming light headed as she launched load after load into the Nurse’s cavernous pussy, seeping down into her very womb. Redheart could feel her belly gravitating floor-wards with each mighty load dumped inside her, and she’d never felt better. She screamed for more, clamping down on Sweetie’s cock in an effort to milk her of every drop she could muster. As the final wave came to an end, Redheart could feel the semen pushing it’s way up her throat. Having filled every inch of her body, it had nowhere else to go. She felt it butt up against the apple lodged in her mouth, before eventually pushing its way past. The apple bounced down onto the floor as the cascade of seed hurled itself out of her mouth.

Studying mammalian anatomy, I'm pretty sure that the reproductive tract and the gastrointestinal tract are NOT connected. Therefore seminal ejaculation should not be exiting the oral orifice unless some kind of internal rupturing had taken place.
