Single host, stealth

Derek's remaining human libido identified the blonde against the back wall as his ideal host. She was tall, maybe 5'10" with upturned B cup breasts set on broad shoulders. Her abs were flat, and a bar was pierced through her clitoral hood.

"Jill, stop rubbing one out in the shower, save it for later," giggled one of the other women.

Even better, Derek thought, an overactive libido.

Derek sent a simultaneous tentacles of slime out from the drain... one toward the light switch and one toward Jill.

Derek shut off the lights and thrust a small portion of his mass up Jill's left leg and into her pussy.

Jill shrieked as another woman reached to turn the lights back on.

"Jill, are you ok?"

"Umm yeah... I think so. I felt something on my leg and a chill in my body when the lights went off."

Derek had by then gained some control of Jill's consciousness.

"You guys go ahead, I think I need to scrub this feeling off my leg."

"Sure you do, Jill. We know all about your scrubbing."

The other women left the shower, and Derek seized the opportunity to finish the job. The rest of his mass flowed out of the shower and into the captive woman's mouth, nose, ears, vagina and anus.

Derek quickly filled and infected the tissue and bone of Jill from head to toe.

Spreading out inside his new host he assumed the memories and physical sensations of this 21 year old woman.

Flexing his new hands and fingers he quickly moved to appendages he was unfamiliar with. Touching a nipple and his clit sent electric shocks to his brain.

Rubbing his clit hard he came twice in one minute.

Wow, Derek thought, I could never do that before. This should be fun....
