Janet Cannot Not Masturbate

A feminine moan came through the vent that separated the two rooms. The smell of raw cock and cunt overwhelmed Janet van Dyne's self-control. She didn't care that someone was watching.

Her fingers pulled the crotch of her Wasp costume aside, the better to access her clit. Ass hovered on the edge of her chair, eyes fixed on the sight of that blonde slut's slit slowly swallowing the superhuman shaft. Janet moaned like a bitch in heat as someone who looked exactly like her friend began to bounce up and down, cunny stretched lewdly, those huge balls ready to fire their virile load into her fertile cunny.

Janet panted, unable to keep her imagination from running away with her. What would it be like, to see that pornstar pussy take a load from that fat fuckstick? What if she wasn't on birth control? They weren't using condoms. A single sperm might be enough. Her fingers twirled faster on her swollen clit as she imagined a sequel where that blonde bitch grew bigger and bigger.

And what if it really was Sue? Janet wondered. What if she got knocked up? I could see her stomach swell, week by week, in that Fantastic Four costume, her husband unaware of what a complete cheating cunt she was.

The image sent a thrill through Janet's body. She knew it wasn't true. That couldn't be Sue Storm in there. It had to be an LMD, a Skrull, some sort of imposter...

The moans were sounds she had never heard Sue Storm make. The blonde was screaming now, slamming her pussy down as deep as it would go, her taut abdomen bulging obscenely from all the cock she was trying to stuff in herself. The pink paws of Porkum were groping those tits and Janet pinched at her own nipple through her costume with one hand, hips vibrating in sympathy to the raucous fucking on the other side.

Utterly unaware of who was watching, or what their plans were for her.
