Gwen experiences the lust of the hellhound.

You can’t hold back any longer. You pounce upon Gwen, sliding your thick, oozing cock up under her little black dress, lifting her legs up and pinning her down in a mating press.

You drive your cock into her pussy unceremoniously, growling in satisfaction as you feel your knot inflate, locking you together. There’s no escape for her now.

Gwen screams and squeals and you pump her. No longer constrained by human limitations like refractory periods, you cum almost immediately, ejaculating gobs of black spunk into your date.

“Oh my god! Oh my god! Oooooh god!” Gwen cries as she feels the pure, concentrated corruption flow into her. She reaches out to Tina, with pleading eyes hoping enough remains of her friend to help her.

“God’s not in the room, babe,” Tina mocks, rubbing her nipples as she watches her best friend get ravaged by an unholy beast.

You dig your toe claws into the floor for leverage as you continue to thrust and hump frantically like the beast you’ve become.

You grunt and snarl as you cum again, grabbing Gwen’s ankles for leverage. You flick off her fancy heels, dragging your slick demonic tongue across her dainty soles and scrunched little toes.

Gwen whimpers, her hands gripping her skull as her mind is assaulted with evil. She half-screams, half-moans, the feeling of violation mixing with impossible, unearthly pleasure.

You hear a snap-click as Gwen spreads her toes into a fan as sharp black talons erupt from their tips. It’s accompanied by bassy moan.

Looking down you see Gwen gripping the floorboards with newly grown claws. Her previously terrified eyes now have a wild, almost feral gleam as their natural blue is replaced by bright yellow.

She finally makes eye contact with you, mouth agape, going silent for a moment as she regards her defiler. Her lips slowly curl up into a perverse grin.

Gwen lets out a lusty hiss. You feel her hips start to buck beneath you.

“Fuck yesssss!” You hear Tina moan. You don’t need to look at her to know the succubus is masturbating. “It’s happening! Corrupt her, my hellhound! Make her one of uuuuuuuuuuuusss!”
