“Ugh… Where am I?” Susan groggily opened her eyes and stared up at the tiled ceiling, bare except the fluorescent lights which idly and softly swung. Her back was pressed against a hard table, her arms stretched above her head. Despite still donning her hoodie the cold metal washed over her back. As she attempted to get up the chains attached to her arms and legs jingled. She was bound spread eagle to this table. “Wendy? Wendy!” She twisted her head as much as she could, scanning the sterile room for her sister. She knew they should’ve gone home earlier but Wendy wanted to stay at the Halloween party just a bit longer. Damn it.

“I see somebody's finally awake!” Susan arched her neck, attempting to spot the person who spoke up in vain. The man’s shoes clacked against the ground, slowly approaching until he came into Susan’s view. A middle aged man with black, unkempt hair wearing a labcoat gleered down through his glasses at Susan. “You don't know how lucky you’re going to be. You’ll be joining your sister as my magnum opus-” He runs his hand down her abdomen and pauses, “Yes, you’ll do nicely.”

“What did you do to my sister!” Susan’s voice shook as she watched the man circle around the table she was restrained to. She could plainly see that he paid her pleas no mind as he left her field of view and began rummaging through a table of surgical tools and needles.

The man chuckled as he pulled a vial of bubbling, purple liquid from the table and filled a syringe with it. “I guess I can show you a peek of what awaits you.” He rested his hands underneath the table near Susan’s head and hoisted it up, shifting her view from the ceiling to a wall with various glass cabinets filled with bottles of chemicals and a cage with an inhuman creature inside.

“Dear god, no. No that can’t be! That’s impossible!” Susan was finding what she saw in the cage hard to believe was true. The creature was wearing a pair of white boots and black knee high socks, on what was supposed to be its torso was a sleeveless black sweater. The exact clothes Wendy had been wearing. It had the lower body of Wendy but everything from her waist up had been turned into a massive and throbbing shaft of a penis. Two sandbag size testicles dangled between her splayed legs, swinging with every pulse of her shaft. She had no head (well no human head to speak of) or face, instead the top of the shaft housed a swollen and bulbous gland which dripped with pre-cum.

“Your sister is wonderful, isn’t she?” He flicked the air bubbles from his syringe. “People will know of Dr. Isaac Hanselhoff’s genius molding of biomass.”

“You’re sick!” Susan hyperventilated, her eyes transfixed on her poor sister as the mad scientist injected her with the syringe. The syringes liquid coursed through her veins as it painfully morphed her flesh and dissolved the bones in her upper body. Her torso lurched and rumbled as her arms were sucked into her body, first pulling against her restraints and then slinking through them as the bio-material was recycled. Her torso grew large and swollen, becoming oddly hard despite the rapid loss of bones. The button on her pants gave way as excess skin pushed past, slowly being filled with her new testicles and fresh cum which rested on her bound legs. The hair on her head fell off as it too began being morphed, her eyes, nose, and ears being covered by flesh as she was forced to look straight up. Her mouth forced open as she no longer had a jaw. She kicked against her leg restraints as her body flopped about the cold metal table, a heat building up in her new body as she felt her torso extend and fill up with blood until her skin was pulled taut over her erect form. From her ridiculous testicles and up her monstrous shaft she felt a warm and viscous liquid slowly be pushed up and well in the back of her throat. Her body throbbed as the excess cum her testicles produced was eventually pushed from her gaping mouth, filling her sense of taste with a salty cream.

Susan’s legs trembled as wave after wave wracked through her. Her testicles clenched as her body spasmed and her head splurged a fountain of white gold down her shaft. She had no way to tell how much time had passed but regardless of how long it had been she had been denied release. Being forced to subsist off the limited pleasure her enclosure brought her… or more accurately her sister. She tried her best to rub her body against her sister’s, feeling the dull heart from her hoodie which wrapped against her torso as their pre-cum acted as a lube. She wanted to scream at that damn mad scientist that they needed release, that her balls ached with the weight of slowly solidifying cum. But if she felt like this she wondered how her sister felt. She’d been transformed and denied the pleasure their bodies were made for much longer than she had. God. she wanted to come so bad!
