Not a chance

The incubus buries its meat in Mary's teased cunt.

“Oh, shit!” she exclaims as her earlier fear is realized. Her desire.

It stays inside her, letting her feel its power as she trembles. Then the incubus begins fucking her in earnest with full deep strokes that seem to explode through her entire body. Her breasts wobble and a fire spreads from her gut.

“Should get help,” she thinks. “Need to warn others. Containment breach. Demon free. Dangerous. Powerful. Seductive.”

Mary moans.

“Jason transformed. Kelly and Mary infected,” she thinks. “Lab unsterile. Options shrinking. Got to lock down area. Beast can't escape. Can't let it near the patients and doctors.”

Mary gasps as she sees Kelly's ass backing toward her face.

“Can't lose any staff. Need them all to fight this. Must be a way to help. Must be some salvation.”

Mary whimpers as Kelly presents her ass to Mary, her slick folds tantalizingly close. Mary's pussy hums as the demon continues to pound her.

“Got to warn staff about the sexy demons. Swollen cocks. Pretty pussies. Dangerous pleasure. Must watch everyone. Monitor for sudden sexiness. Check yourself for unexplained arousal. Stay away from thick cocks and juicy pussies. They may be tastier than they appear.”

Mary leans forward into Kelly's pussy at last. She wastes no time plunging into the hot cunt, its smell and heat overwhelming her senses. Kelly squeals as her labmate tastes her pussy for the first but definitely not last time, her eagerness more than compensating for any lack of skill.

“Definitely tasty. So wet and ready for me. Ready for him. Ready to fuck. Ready to fuck and keep fucking. Should stop. Don't wanna.”

Kelly's slick folds swallow some of Mary's cries as the pleasurable **** continues, Kelly's juices growing more delicious seemingly by the second. The **** of the demon plowing her rocks Mary back and forth on the floor, and she hangs on to Kelly’s firm, rapidly reddening ass with steely intent. Mary’s veins are on fire and her thoughts sparking away with the unrelenting fuck as yet another orgasm detonates through her.

If Mary could see beyond Kelly’s addictive cunt and think objectively, she would marvel at the scene, a dusky red Kelly above her passionately making out with their third labmate, both with bodies that would incite lust in the most chaste of humankind. Black horns sweep back from Kelly’s head, and Holly’s hair and skin are headed in opposite directions like ships passing in the night. Her skin is flaming to a brilliant red while her wavy head of hair is bursting into a dazzling alabaster with the autumn of her soul. Budding nacre horns shine low above her scalp.

Mary’s skin is feverish and her tits ache. She tears herself away from Kelly’s backside to fumble with the buttons of her shirt with slick fingers. Before she can navigate a single button, it’s destroyed by Kelly and Holly gleefully pulling in opposite directions. Holly’s tongue swirls in Mary’s mouth while Kelly plays with her breasts and the incubus pistons in and out of her needy cunt. Mary screams as the sensory overload rips her soul from her and delivers her to Lilith.
