The girls woke up the next morning, Jenny and Dani on the floor and Sunny in the bed. The preceding night's events had locked in a few more traits on the original infected.

Dani's breasts were now at least D cup, and perkily pointed to the sky, topped by marshmallow puffy areolae and gumdrop nipples that still had dried milk crusted on them. Her clit was as long as her thumb with labia descending behind it to match. She struggled to button on the one billowy sundress.

Jenny stood up and looked in the mirror at the muscle mass gain that remained. Some veins were still visible radiating across her body, the primodial thread winding down to the tip of her clit. "Dani, I'm worried... I can't go out like this, no one will understand the overnight changes... and look what happened to my clothes!"

"I was stressed out at work too... but no one uninfected seemed to noticed. The same hormones that seemed to hypnotize others before we change at night also seem to cloak us from scrutiny during the day."

Relieved of her worries, Jenny asked "Well, Sunny, we need to know what happened last night after we came. It seems like a side effect of the rush is not seeing what happens next."

The question didn't register momentarily as the redhead gathered her bearings and looked down at her naked normal human form.

"Oh yeah", said Dani, "the virus we passed on to you seems to only trigger at night and returns you to some believeable human form in the morning."

"Well, except that with every experience infecting someone else, a little more of the change seems to be left behind", added Jenny.

Sunny had a clear memory of the nipple mating, the breast expansion and being hoisted aloft on two enormous penises but couldn't register that it was all gone. Snapping out of her daydream, Sunny began to tell her story of downing the synthetic cocktail after the other girls had passed out. "My breasts grew down to my thighs... I straddled Zach, sucked him off and jerked off my own cock or clit or whatever after it had travelled the length of his body, emerging from his anus."

"Wow, wild... hey, where is Zach?" asked Dani, noticing the frayed ropes still attached to the headboard.

Searching the apartment they found him prone, cold and **** on the bathroom floor. Dragging his body onto the bed they were relieved to still find a pulse. The sun shone brightly though the windows and a ray hit his blue skin, triggering the dormant mutation. The girls watched as the virus attacked a genetic male... All the follicles of hair receded back into his skin.... his features softened, his hips widened... The now bare skin on his chest bubbled as buds of breasts formed and pushed out to fully formed womanhood. His limbs, feet and hands shrunk. Finally, the hair on his head faded to blonde and lengthend to his prone shoulders. A vaginal opening formed in his perineum. But, instead of following suit, his penis crept down the sheet to his knees and then reversed course, not shrinking but retracting with his testes up into the uterine cavity inside his mutated body. The supermodel/cheerleader/pornstar figure stirred, sat up and started to speak a stream of consciouness ramble "I watched all of you, all of that, last night, whatever that was... Sunny, I don't know what happened after you sat on me. I passed out... I had a dream that I wanted all of it, everything I saw, the apex feminity and apex masculinity all of the time." Her voice trailed off as her stomach began convulse. A pressure built in her abdomen and she grunted and pushed out the frenulum... grunting over and over the cock shaft emerged inch by inch giving birth to her dream. It rose erect three feet in length, veins pulsing. Two testicles followed with a sucking sound as the morph was complete. Zach or whoever she was now, came hard, covering the ceiling and dripping back down on the stunned onlookers. Dani thought to herself... "I'm the perfect trap by night, and now I've seen the perfect trap by day." The future was futanari. The girls opened their mouths and ingested a new strain.
