Gwen laughed viciously as she rammed her cock into Mary Jane's ass. They symbiote around MJ's body began to send large tendrils into her cunt, pleasuring her there too, causing Mary jane to let out a loud lustful moan. "Mmmm. You love this don't you bitch?" Gwen asked her captive. "Peter has been so busy fighting crime that he has so much trouble fulfilling those sexual desires of yours. But don't worry, your lustful desires will soon be your very being!"
"Wh-ohhhhhh-what are you -gah- talking about, Gwen?" Mary Jane asked, beginning to drool from the sexual bliss.
"I have given myself to the Deviless! I have been reborn as the Demon Queen of Lust, and soon, you shall be my first Lust Demon!" Gwen said as she laughed.
"NO!" Mary Jane said, moaning and groaning as Gwen rammed her demonic penis into her, and soon felt a load of warm cum being launched into her, as Gwen let out a loud orgasm.
Gwen stopped for a moment and pulled out her dick. It was coated in cum and pussy juices. "Mmmmm. That was good, bitch. Now let me see that cunt of yours! I feel like going another round" Gwen said with a sinister grin, as she stroked her cock.
The symbiote again forced Mary Jane to move against her will, but this time, she didn't feel as if the symbiote was being as forceful, almost as if her body was acting on it's own this time.
