Ritual of Corruption (clean)

Argent arrives to his friend Syrios's house answering one of her usual booty calls. Fully expecting on arrival to be taken into a bedroom, over to the couch or bent over the kitchen table and get his ass spread and wrecked by her massive demon cock.

As usual when he arrived he found her in her dominatrix gear with her cock and balls hanging out on display but this time instead of instantly grabbing him and using him as a sex toy she makes him an offer. To turn him into an incubus like herself so he can serve her for eternity. Which most likely means just getting railed by her for eternity, a proposition he found hard to pass up.

Agreeing to her offer she teleports them both to a room with statues and a magic circle inlaid on the ground. Walking over the circle at her behest the kobold suddenly finds himself wrapped up in golden tethers of magic and suspended in midair with Sy behind him stroking her massive hardon.

With a wave of her other hand she creates a doppelganger of herself an explains to Argent that the ritual is going to take between 6 to 8 hours to complete and during that time her and her clone are going be spitroasting him the entire time. Pumping load after load into him till he overflows and their cum drips down onto the circle, starting his transformation.

With that explanation and a swat to his rear she quickly penetrates his ass while her clone pushes her own massive hardon into his mouth and so the ritual begins.
