Dustin studied his body in front of a mirror within his room. Something was not right. Ty did something to him, but what exactly, he did not know. He no longer looked like a teenager boy of 16, but rather a preteen on the verge of puberty.
"I'm going to make that punk pay." Dustin growled, knowing full well that his step brother would be soon returning from his sudden babysitting job with the little pipsqueak across the street. Right then, he heard the doorbell ring.
"Dustin!" His father yelled. "Get the door, will ya!"
Dustin obliged, and he made his way to the front door. Grinning at the thought of what awaited his younger step brother tonight.
Unlatching the locks, Dustin swung the door opened. Two massive pairs of tits caught his eyes. Dustin gaped as his mind froze, before him stood two incredibly gorgeous women. One with platinum-blond hair, while the other's hair was black like obsidian. Both girls were wearing tight tank tops that displayed their massive bosoms, and hugged their hourglass figures. Hot pants pressed against their hips, but could barely contain their ass.
"What's wrong big bro? Cat got your tongue?" He heard a familiar voice snicker.
Ty emerged from between the girls wrapping his hands around their thin waist. Bring the girls closer, they giggled and kissed the teenage boy between them as their massive breast pressed against him.
"Ty? W-what's going on? Who are these girls?" Dustin stuttered, his bewildered could barely masked his jealousy.
"Just Katherine and her friend Megan." Ty smiled.
Before Dustin could process the names, the three of them entered the house. Dustin remained speechless, but gasped as he watched the girls' asscheeks squeeze as they walked.
Mark watched as his foster son entered the living room. On his sides were two provoked grown women. Mark's eyes open wide, along with his mouth. His wife June by his side, just as stunned as her husband.
"Boy!" Mark finally yelled. "Just who are these two harlots you brought into out home!"
"That's not a very nice thing to say to these beautiful girls. It was you who told me to watch over them in the first place." Ty grinned.
Mark gritted his teeth as he began to raise his body.
"That won't do, you can stay put for now." Ty commanded.
Mark felted his body become weak, slumping back down.
"It's time you all realize that I am now the man in charge in this household, and as proof..." Ty grinned. The two girls left his side as they approached June. Lifting his step mother's body with ease, she felt a strange power overwhelm her, preventing any needs for resistance.
"Mark!" She barked, "Don't just sit there and watch, do something!"
As the two girls foundled her body, and kissed her cheeks. Mark noticed her clothes seemed looser around her body. June was getting thinner, and fast.
"What's... Happening... To me!?" She gasped as a response.
The two girls tore the clothes of June, revealing her tight figure. Her hourglass shape had returned, while the stretch marks she got from Dustin had vanished. Her breast were now perky and firm. As the shirt lifted above her head, a face belonging to a woman decades younger reappeared. June had become the woman Mark once remembered many nights ago. Mark watched as his foster son unbuttoned his jeans. Pulling it down, Mark stared wide eyes as the teenage boy whipped out his hard long nine inch cock. Slapping his wife on the ass, Ty positioned his body.
"This can't be..." Mark grunted, seeing his son Dustin watching from the doorway, as hopeless as his father.
June eyes widen as she felt the tip of Ty's dick began to enter her. He legs trembled, as her pussy was drenched. She knew this wasn't right, but her body yearned for it regardless.
"Oh! Fuck!" She yelled as Ty thrusted inside of her.
The two engaged in sex, as the other two girls giggled as kissed their bodies. This lustful display only made Mark hard despite his apprehension. His own arousal betraying his pride. Mark did not notice that Ty had cast other spell over his body. As Ty fucked his wife, Mark's age slowly regressed back. Muscle, fat, and wrinkles all began to revert back to a youthful form. Mark's facial hair receding as he re-enter teenagehood. Mark began to lose his identity as himself, the only thing driving his mind is the horniness caused from the display in front of him. The teenage Mark unbuttoned his jeans, and whipped out his dick. It was a lot smaller than Ty's and much more unimpressive. He began to masturbate as he clenched his teeth, he wasn't going to last long at all. Looking to his side, a young baby draped in oversize clothing ducked his thumb by the entrance way.
Turning his attention back at the three moaning girls. Ty was still fucking his wife from behind, but all memories of their relationship had long since pass, the other two girls had stripped their clothing off as well, both getting fingered by Ty all the while.
Watching these three sexy girls in the prime of pleasure, Mark huffed as he felt his ball bulged.
"Oh! Fuck!" He groaned as a mighty stream of cum erupted from his cock. Like a deflating balloon, his age plummeted with the seamen leaving his body. Soon only another mindless baby watched them. The pool of cum before them was Mark's last feat.
Ty smiled as he pulled his dick out of June.
"Kat, Megan, watch over the babies. June and I are going to continue our fun somewhere a bit more private."
The girls giggled as they obeyed their former babysitter. Ty lead June to the master bedroom closing the door behind them.
From there Ty gave June the best sex she had ever had in her life. Her body trembling hard after every orgasm. It wasn't long until both her body and mind belonged to her former step son. The night finished as Ty blew his massive load inside her, finally allowing her to rest.
Now that that was done, Ty grinned as he wondered about his day tomorrow. There was plenty of people at school he could think of. Mrs. Wilson, a snooty old bag of bones that insults him daily, to Cindy Harper, cheerleader captain that never gave him the time of day.
"Tomorrow is going to be fun..." Ty grumbled as he began to doze off, his former step mom clinging to his side.
