(Original author here: I am embarrassed to admit that my first attempt at this story branch was a bit rushed and lacked a lot in some key areas. While I feel like this is in bad form, I have rewritten the branch from here.)
With a flash, the light in the room went dark before rising back up slowly. Madame Illusia held out her hands to the heavens and squeezed her fingers tight into her palms. Damon felt as though he was punched in the gut as he scrambled to his feet which were quickly rising up to meet him. Monica watched in fascination as Damon continued to shrink, dwindling past 10, past 8, past 6… This wasn’t exactly what she had thought would happen.
“Monica?” Damon looked up at the woman who was once his beautiful younger girlfriend. He could barely see her past her new melon-like tits that were capped with darkened nipples and plate-like areola. “Monica, I, I…” His voice was like a high-pitched, almost feminine squeal as he continued to shrink. “I love you.” Two years old now, Damon was losing his balance and his hair was thin and wispy.
“What’s happening?” Monica asked, more curious than worried. Jason has already taken his opportunity to push his impressive cock inside of her and was working it back and forth slowly. Monica was in something of a sexual haze as Damon dwindled away.
“He’s going to be your son, right?” Stephan responded. “He’s got to start over to do that.”
Damon was soon just a naked baby, fallen onto his back with his arms and legs kicking impotently in the air. Somehow he managed to keep himself from crying despite the panic that was building in him. Monica was going to take care of things. She was going to be his mommy and he could be her little pervert boy. He was finally going to chase his fetish all the way to a new life.
“Start over? Start over as what?” The 42-year-old woman’s eyes were wide with worry. She looked back at her boyfriend to see baby Damon shrink smaller and smaller until nothing was left except for a hot pile of semen. Monica leapt up as it passed under her and Jason’s feet. The teen pulled out of his MILF-y partner in sudden shock, but didn’t have time to react before the cum puddle that used to be Damon slithered into his cock and caused his balls to gain a not insignificant amount of weight. Jason moaned in pleasure as he felt the pressure to cum build up quickly in him. Without really thinking, the young man began to stroke his hand across his massive dick.
“That’s not what I meant!” Monica exclaimed, her eyes wide more with anger than worry. “I’m not going to be pregnant. Not with HIS baby!” She jabbed a finger at Jason. “Look at me! I’m a sexy MILF bitch. I’m not ready to start a family this late in life. This body is made for sucking and fucking, not chasing after my weak spined former lover. I don’t want a baby - that’s not my fantasy, that was his!” She lowered her finger to point at Jason’s hefty ballsack. “I was getting what I wanted with his little kink, but now… what’s the point?”
Jason was taken aback by the outburst, but he couldn’t stop his cock from standing up at attention. Beneath, two softball sized balls looked to house the remains of Damon as he pumped at his cock. If Damon held any more thoughts, he surely would have been humiliated to be nothing more than a sperm among thousands in the balls of his girlfriend's temporary virgin lover. Even now, the teen Jason could feel the building orgasm that would soon release Damon.
“This is the only way for your cuckold lover to be reborn,” Madame Illusia intoned, resting on the stage, weakened from the extreme use of magic. “I can do nothing more from here other than to guide Damon deeper into you.”
Monica’s jaw was held open in shock, but she seemed to understand what she had to do. Monica sighed and pulled her hair back away from her face. She felt her face had lost some of its luster and bounce as her fingers traced lines past her new crow’s feet and deepening laugh lines. Getting down to her knees, she crawled over to Jason, displaying her thick, wobbling ass to everyone in the tent. Jason didn’t even fight it as she wrapped her lips around his cock and slid it down her throat without a hint of resistance. The teen grabbed on to her head, but the MILF was quicker, snapping her neck back and forth, and building up a thick layer of saliva. Her hands busied themselves: one rubbing away at her clit while the other cradled Damon’s home in Jason’s balls. Monica found that there was something intensely satisfying and hot as she slurped away at the impossible cock where her once-older boyfriend had slithered into. Now he was just a worthless little calorie among millions living in a teenager’s nuts.
“Oh, fuck, I’m gonna - I’m gonna-”
Monica didn’t stop, instead reaching out to grab the teen’s ass and pull him down deeper into her throat. Jason convulsed as he had the most mind-shatteringly powerful orgasm of his life. His balls heaved up and down against the woman’s chin as he let loose rope after rope of the former cuck down Monica’s throat. The cum built up within and without, bubbling out from behind her lips and dripping from her chin to the stage below. Breathing out of her nose, the MILF waited for Jason to finish before slowly easing her mouth off of his cock with a loud pop. Thick strands of cum-Damon mingled with her spit, making little bubbles that dribbled from her plump lips.
Wiping up the cum-cuck mess and feeding it back into her slutty mouth with a dainty finger, Monica shrugged. “I told you I’m not ready to have a kid.” The now softer, bigger figure of the 42-year old MILF Monica got to her feet and displayed her body for all to see. Weighty breasts hung down lower than before, but now round and fatty, with dark nipples that seemed to beg to be sucked on. Her once petite yoga-ass had ballooned out past her hips with the hints of cellulite and a mesmerizing jiggle as she moved. Her twat, still caked in her own juices and Jason’s precum, was a hairy jungle that was covered slightly by the thin amount of pudge that had grown over her stomach. She let her hands feel up her body excitedly, already forgetting that she had just swallowed down her former older boyfriend as a little cum snack. “I’m going to need some new clothes,” she mused before looking out at the audience. “And at least two or three more good fucks before the night is over.”
