He drinks it.

With a nod to Rosaline who looked at him with a lustful smile on her lips but a yearning for him to be hers in her eyes, he leaned over and grabbed the jar with both hands. “To a new life” he whispered to himself before he opened his mouth and tilted the jar back causing the thick substance to pour directly into his mouth. It filled his mouth quickly and he had to swallowed quite a few times to get just the first mouthful to go down his gullet. He noticed the taste; it was so good. He wanted more, no…. he needed more. It was then he felt the first changes to his body. He felt his throat get a bit wider which allowed hm to drink the cum faster as he poured more of her delicious cum into his mouth. He felt his hips widen and his hair grow a bit longer. His nipples ached as he felt them get pushed outwards slightly by a lump of skin. He continued to swallow the cum, moaning now due to the taste and the pleasurable tingles of his body changing. His small cock which had only been 3 inches started to shrink, soon it was two inches then one then nothing. Out of the empty space that his cock used to occupy, appeared a small slit that turned quickly into a dripping pussy. His tail and hair, both of which had been brown, were now pink with galactic like colors on the ends on the tail.

Finally, James who was now fully a girl, was reaching the end of the jar as he swallowed the cum as soon as the virile spunk entered his mouth. In his lust, he had ripped his clothes from his body, wanting to embrace his change. The last change to his body was the telltale sign of a slut owned by a futa, the tattoo. It showed anyone that the slut has been marked by a futa. It wouldn’t stop other futas from using the slut, it was almost like a futa brand on the body.

Rosaline looked shocked at James’ new look, she had seen clips and read about less dominant males literally changing into females due to the aspects of futa cum. But it was supposed to be very rare, and Rosaline just happened to have one of the males as her best friend. But now, her best friend was now her harem slut.

James used his hands to scrap any more cum left in the jar into his mouth, moaning and maybe even cumming to the taste of his new mistress’ cum. He put the jar back onto the table and moved closer to Rosaline. “I guess now that I’m a girl, you can rename me. But at the moment, I just needed more of that delicious cum or your amazing fat smooth cock in one of my pathetic holes!”

Rosaline smiled at James before saying “I’m gonna call you Jamie. Not a huge difference but I would forget it otherwise. But wow! You look amazing and so fuckable. I can’t wait to use you!” Rosaline’s cock returned to being fully erect looking over Jamie’s hot and petite body, and she grinned as she remembered part of the information on males who changed into females with futa cum was that the new girl would be able to take any cock easily into any hole.

Jamie grinned at her new name and the prospect of her new life. It isn’t like the old her was gone, she could remember being a guy and lusting after Rosaline, wanting to fuck her. She did that too but now she wanted Rosaline to fuck her until she could barely move. Her life was now to please Rosaline in any way she wanted, sexual or otherwise.

However, even though Rosaline had gained a slut who had been changed by her cum to specifically meet her needs, she was nervous. By all rights, she could jump on Jamie and pound her until next morning and Jamie would beg for more at the end. But Rosaline was inexperienced, a virgin, only herself had touched her cock and the past insecurities were running through her mind, what if I don’t make her cum? What if I cum too early? What if she doesn’t enjoy it? What would Jamie’s parents say about their former son, now daughter being a harem slut to Rosaline?

Rosaline was like a deer stuck in headlights, unsure on what to do even though she was so close to fulfilling her biggest fantasy. But thankfully, she didn’t have to choose when she felt a warm sensation on the tip of her cock. She looked down and saw Jamie with her cock tip in her mouth, not moving up and down, just suckling like a baby sucking on a tit, eager for their next meal. Slight moans from Jamie travelled down the shaft, causing Rosanne to shiver with pleasure. She was sure she wouldn’t last long but she hoped her improved stamina from the gym and that she can usually cum multiple times in a single jerk off session.

Jamie continued to suckle on her mistress’ fat bulbous cock tip, she could feel the shivers of pleasure she was delivering to her mistress and promised herself that a day wouldn’t go back without her draining her mistress’ balls. She laid down on the couch, getting comfortable as she continued to suckle on the precum leaking cock tip. The precum tasted amazing, like honey, sticky and sweet. Rosanne’s cock was throbbing now, signaling how close the second orgasm would take to arrive. Jamie didn’t care as she felt the throbbing, the need to cum and so started to move her head forward, taking a couple of inches of cock. Rosanne moaned at the new pleasure as Jamie started to move with a rapid pace up and down the first couple inches of smooth, fat cock. She used her lips to suck intensely, molding her face into a “0” shape to grant her mistress the best pleasure. Her tongue flicked and explore the cock tip as the mouth pleasured the shaft, combination of which was breaking down any futile resistance Rosanne had about cumming so soon. But Jamie wouldn’t just take another load with a small blowjob.

As Rosanne started to shake in pleasure, screeching at the most intense orgasm she had ever had as cum started to rush from her tennis ball sized gonads into Jamie’s mouth. Jamie started to swallow as she flung herself forward, taking all 9 inches of smooth sturdy girl cock into her mouth and down her throat. Strangely, it wasn’t painful or uncomfortable to Jamie to **** a massive cock down her throat, it felt natural, good even. As Rosanne’s balls started to squeeze out more cum than she had ever shot before, Jamie started to throat her mistress’ cock, gagging as spit started to fly from her cum stained mouth onto her cute innocent face. A myriad of sounds echoed around Rosanne’s living room as moaning, gulping and gagging could be heard. Jamie swallowed the thick, delicious shots of cum with a little difficulty as she continues to mindlessly facefuck herself on her mistress’ pulsing cock. As Rosanne’s first orgasm via slut ended, she collapsed backwards onto the couch’s arm, feeling totally exhausted as Jamie cleaned her cock, slapping the meaty slab on her face a couple of times.

Jamie has a face coated with left over cum and her own spit, any innocence that her new girly face would have portrayed, now only showed a true harem slut. She made a quick trip to the bathroom for a towel which she brought back with her, cleaning her face. The amount of cum she had just swallowed from her deepthroat was easily more than the jar full she had downed only minutes prior. It still affected her, making her horny for more but also revitalizing her energy and Jamie knew that she could solely live off Rosanne’s cum. Jamie wondered if she could squirt and if it would have any effect on her mistress, maybe it boosted cum production or made her ready for more pounding. Only one way to find out as Jamie definitely wasn’t done playing with her most favorite thing in her new girly life.
