While Krissi and her new girlfriend/toy/pet went about their evening, June felt a rush of excitement as Mark belched in the bathroom, shaving for Sunday morning's work day.
She covertly stopped by Ty's bedroom and saw the shut door and dimmed lights. He was waiting for her, he knew. More kinky transformative fun awaited her. What would he do, she wondered? He had been experimenting with Dustin all evening in his bedroom. Remotely! What had he wound up doing to him and Krissi? With just mere thoughts!
What power he had! She gulped as she felt her pussy tingling in anticipation.
Mark staggered to the bedroom, scratching his fat ass, and yawned. "I'm heading off," he said to June on the way by. "You staying up tonight?"
"I want to catch the late show." She said coldly. As was their Saturday routine. Mark nodded simply, shut the bedroom door behind him, and she heard the creak of the old bed and the loud box fan turn on.
June positively bolted towards Ty's door and tapped it gently. She felt like a child. She felt like a big naughty child.
Ty cracked the door with a huge grin and she could see he was already nursing a hard on in his hand.
"What were you doing?" She whispered gently, eyeing his dick and grinning back.
"Guess I was keeping it warm for you," Ty chuckled quietly. "Gods, you won't believe what Krissi did! I let her change Dustin and well, uh, he's not her BOYfriend anymore, if you catch my drift."
"Jesus!" June blushed. "I don't have a son anymore?"
"Nah," Ty peeked out the door and down the hallway. "Is he in bed?"
"Yeah!" June nodded excitedly.
Ty closed his eyes for a moment, then opened them and grinned seductively. "He won't wake up for anything tonight."
"Oh God!" June blushed, practically dancing in the hall. "Well, let's go! Come on!"
June entered Ty's room, grabbed his naked body, and pushed his face into her tits. "What do you wanna do to me?"
"Mmmph." Ty grinned. "Well, I've been... playing with animals."
"Animals?" June pulled back, awash in fresh excitement. "You mean making people animals?"
"Well, just Dustin. I didn't touch Krissi. Didn't seem right to subject her to noncensenual transformation."
"I guess," June flopped down on his bed and eagerly stripped away her night gown. Just her panties remained. She giggled and rolled over. "What did you make him?"
"Uh, he was a giant mosquito for a while. Then a spider. Uh, a big snail. Birds, mammals, I didn't really try reptiles. Krissi almost made him an elephant and then backed off of it. So I didn't go too big. Man, did I mess with him, though!"
"Oohhh!" June grinned from ear to ear, giggling as Ty crawled into the bed with her and his hand went right for her somewhat wet panties. He slipped his hand under the waistband and his young fingers began to probe a now familiar pussy. "Mmm, that feels good! So, what do you wanna do to me, baby? Bigger? Smaller? Fur? Feathers? Scales?"
"Hey, first things first," Ty grinned, so confident now that he began manipulating June's clit under his thumb and index finger like an old pro."
"Ooohhh, Ty!" June moaned. "You're gonna make me cum again."
"That's the idea." Ty whispered, reaching up with his other hand and stroking her dark brunette hair. "But first, my beautiful step mom, let's do something I haven't done yet."
"Ohhh, yesss!" June hissed in sexual bliss. Ty knew what he was doing with her now and as he tickled and massaged her clit she felt herself growing wetter and hotter. She moaned and closed her eyes, throwing her head to the side. "You change me however you want."
Ty closed his eyes, stroking his bone a little with his other hand and feeling June get jucier and more swollen under his other busy one. He wanted to make June more his age. He willed her to regress.
June bit her lip hard and moaned as Ty continued to pleasure her. The well of hot transformative energy spilled out across her body again and she arched her back, grunting. "Fuck. It just keeps feeling better and... and better!"
"That's good. Savor it. Let it wash over you."
"Yes! Yes!" June whimpered, "I'm all yours!" She jolted a little as she slowly began regressing. As Ty worked her clit in the darkness of his bedroom, her panties began to loosen a little on her thighs, because her thighs were shrinking. Indeed, all of June was rapidly deflating. Her breasts lost some weight, her chin pulled tight. Her flabby ass toned rapidly, and her overall figure began to trim down.
"Lighter..." She gasped, lying back and starting to hump into Ty's hand a little. "I-I feel lighter..."
Ty said nothing, watching in the dark as June aged backwards. Lines and wrinkles on her skin began to pull tight. The aged tone of her skin began to fade younger and smoother. She was in her early 30's now. She was substantially thinner, less droopy, and much more attractive. He could even feel her pussy lips tightening around his fingers! God, he couldn't wait to fuck her young pussy.
As she fell into her tight and toned mid 20's, June's hands shot up and grabbed her tits. Sudden realization set in and she sat up in startled surprise. "Oh God..." She heard her voice. "I haven't felt them this firm since... since..."
She realized what was happening as she began to slim in her early 20's and lose her womanhood. That soon turned to inches and she began to shrink in her regression.
"Oh my God!" She threw herself back, hearing a voice she hadn't heard since she was 18, and began to whimper as she lost her adulthood. Ty felt her pussy quivering under his touch and kept up his steady rythym. June had already lost her six foot stature and was down to 5'9" or so.
"Geez, you were tall for your age!" Ty beamed.
"Y-Yes!" June gasped, bucking harder and feeling herself on the edge of climax. "Ungh! Don't stop!"
Indeed, once 17, June was still nearly the same height and holding steady while her breasts and her development ran backwards. She slimmed dramatically, her legs and arms long and her torso quite skinny. Not very busty at 16 either, when she still stoof 5'6".
At 15, June began to tremble in lust and her young voice cried out. She was right on the verge of cumming. Ty relented, pulling his hand back with a healthy slurp, and marvelled at the willowy and nearly flat chested 15 year old his step mom had become. She was shockingly lean and plain, with barely there breasts and a body that resembled a stretched out child's.
"Why'd you stop?" June panted, sitting up and trembling as she looked over herself in awe. "Holy shit... I'm... I'm so... I forgot how fucking small I used to be!"
"Underdeveloped?" Ty offered, raising a patronizing eyebrow.
"I-I guess so!" She blinked in realization. "So, what do..."
Ty was on her in moments. He pressed his down into the bed, grabbed her shoulders, and mounted her. June blushed deep red and squirmed a little, but Ty held her down and slipped in with ease.
The two 15 year olds began to moan and writhe as they fucked. In her young and energetic body, June was eager and horny as fuck. She threw her legs up around Ty's back and bounced him into her. She barely noticed as Ty grunted and began to grow older himself. The 15 year old girl was suddenly being fucked by a 16 year old boy. Then a 17 year old. Then an 18 year old.
June screamed out loud uncontrollably as his prick grew within her loins, stretching her full as Ty increased his development and manliness to the proper level. Ty lifted her off the bed as she came, easily holding her tiny body up by the ass, and madly fucked her pussy with an eight inch adult cock. June began to convulse as she came again. And again. Her young body was saturated with hormones and horniness. Ty let out a grunt as he blew, and soaked her pussy and her inner thighs in cum. The young girl gasped as he pulled out, panting wildly and sweating hot.
As her mind cleared, she went ashen as he looked way up at a buff and manly Ty, absolutely ripped with wild blonde hair and chiseled chin.
"Ohhhh my God." June gaped in shock. "What'd you do to us?" She was beggining to take on the mannerisms of her younger self with all of her adult mind intact.
"Just reversing the age gap, little girl." Ty grinned, setting a shocked June down on the carpet and holding her up by the armpits as her legs regained strength. She stepped back from him in awe and turned beat red.
"What would your daddy say if he knew you were messing around with older boys?"
June blushed deeper red and laughed nervously. "If my dad had ever caught me taking dick from a grown up, you woulda gotten buckshot to the face."
There was a moment of silence as June reached down and touched her still creamed and wet pussy. "I... I didn't fuck until I was like 22," She admitted. "You've uh... ya definitely deflowered me ahead of schedule, step son."
"Shut up, you like it." Ty giggled. "Although, I do miss your titties."
June blushed again and unconciously covered her chest in embarassment. "Yeah, they didn't grow in until I was almost a woman."
"Mmmm," Ty nodded, stroking his manly fingers through June's hair and watching her squirm. "So, uh, everything still there? You're still you?"
"Yeah, yeah..." She nodded nervously. "I just... I'm back to how I used to be, I guess? Like, really, you know... meek? Like nervous?"
Now standing over six feet tall, June gulped as she looked up past Ty's sexy pecs and blushed again, clutching herself. "Man, you were... big. Like, how much did you grow your dick?"
"I'm just eight inches." Ty shrugged. "You're just small as fuck."
"Stop that." June looked away sheepishly, hormones raging. "Yeah, I was a small girl when I was your age. Or... you know. Like no hips, no ass, no curves at all. Man I got shit on for that." She held out her arms and inspected them, shocked as Ty reached down and took her wrists in his hand. He dwarfed her enough he could easily curl his fingers over arm with room to spare.
"I like you this way." Ty admitted, willing himself to reduce back down to her age, and shrinking into a new form that was essentially a properly developed Ty. June swooned as the awkwardness faded and she threw her arms around Ty's built neck.
"Yeah? So whatcha gonna do with teen me now, huh, my changer?"
"How would you like to try out some new species with me tonight?" Ty grinned.
