You were excited when Gabriella drank the potion without a second thought, but it would be an understatement to say Jenny was excited. She was frantic, rapturous even. Words weren't reaching your mind anymore, all that came out of your she-cock was pure animal lust and an insatiable need to be fulfilled. When Gabriella wrapped her slim fingers around your cock you and Jenny nearly came with how needy she had become. The soon to be absorbed woman opened her mouth and only just barely managed to fit her mouth around your massive cockhead. Jenny cooed in joy as you placed a hand around the Latina's head encouragingly.
With no small amount of skill she licked, sucked and kissed your elongated pecker, all while her features began to shimmer and melt as her body was affected by the potion. After a serious 'suck' you felt Jenny give way as she began to spurt load after load into the poor woman's mouth, and you watched in orgasmic awe as she gulped it all down. As the finally spasm kicked off, you saw her lips had begun to merge with your cock finally. You pushed, and your cock began to slide into Gabriella, far further than it had any right to and with little to no resistance. Her body was quickly losing cohesion as her limbs were sucked into her form and her face lost definition. Further down you saw that her ass was taking on a familiar shape. Her cheeks were slanting away as her asshole lengthened. As her body shrunk into yours, her butt finished becoming an exact copy of the head of a penis, albeit a darker tone that your original/Jenny.
As she flowed into you, you felt another couple of inches added to your height, and felt a ripping sensation all over your body. Your form had finally stretched the limits of your poor clothing. Your hips had become much wider, and the inkling of strong muscles in your arms and legs left your clothes no chance. You were glad you had no bra on too as your previously small breasts exploded into what your guessed must have been a D-cup at least. Even your face felt different, and an exploratory feel proved at the very least that your lips were thicker.
Back down to your engorged and much larger cock, you felt the strangest sensation of pulling. Jenny was moaning in ecstasy, and as you felt the pulling sensation another voice joined hers. It was Gabriella, herself moaning in senseless pleasure. You felt a sudden pressure centered around your sentient package and watched in awe and some horror as your dick appeared to enter mitosis. Your cock pulled in opposite directions as two cocks formed, each slightly smaller than the massive one compromised of both women, yet still larger than before you absorbed this new woman. On the left was what had to be Gabriella, as this prick had her skin tone and tuft of pubic hair was her color. To the right was Jenny, with her much lighter skin tone and hair. they seemed to be split down the middle, oddly enough sharing what you discovered was a third testicle in your overstuffed ball-sack, separated blurred fusion of the skin tones.
"Mmmmmm, this feels so ggooooooodddd!!!" you heard Gabriella moan.
"Welcome to the party girl, it's so much fun being a cock!" Jenny said.
"Dios mio, I feel so sexy and powerful! MMnf- put me in something, anything, I want to fuck!"
You patted your new cock-girl lovingly. "Soon, " you purred in your now more womanly and sultry voice. "Do you girls want a third member maybe, just to round things out? Three's a party after all." The dicks gave you overwhelming approval and your turned to Cass and asked to compete just one more time. She agreed with a huge grin and had another contestant step up.
