Ty grinned as he viewed June on the couch lazing around a little. She had finished exercising and was still in her exercise shirt and skin tight pants. He thought that he may as well do more than just change her gender but...
June took a swig of water and then felt a tingling at her groin, and then a tightness, and then as she glanced down she saw a bulge snaking down the side of her pants. She gave the hardened thing a pat and was surprised to put it mildly. She was familiar with dicks as it took a few times to get Dustin, but it was weird that she had one. The shock having worn off she was looking around and sniffing her water to see if someone may have snuck... some sorta experimental drug in her water? She then scratched at her chest... it was just feeling itchy under he sports bra... itchy and- June looked at her chest and saw hairs growing on her chest, and her breasts were looking a lot... flabbier? Then she felt a bloating feeling, and a few seconds later she noticed her arms getting chubbier and then her gut under her breasts growing. Her breathing got more labored and deeper as June got more scared at what was happening to her, and as the amount of blubber she was accumulating was making breathing a small issue. Then finally her exercise clothes changed to a pair of boxers, and a shirt that didn't even cover her gut. Add in a few other details here and there like her long hair turning into a short receding hairline. What had once been June was now Jack, some lazy adult of a man.
Ty snuck off leaving June to panic inside the body of Jack, and then went back to his room. Mark was off at work, but Ty didn't have to worry about something as minor as distance ruin his plans. Ty faced his bed thinking of making Mark's change a little more... Gratifying to himself.
Mark was at a local retailer as a manager, and was confiding in a Karen that she shoul-... Mark silenced himself and took a quizzical look around as he was in front of Ty and in his room now. "Ty!" Mark shouted before his mind could make sense of what was happening. Then he seemed to shrink and in a sec had to look up at Ty a few feet up. Looking down Mark saw that he was now swamped in his shirt as his pants and shoes were pooled on the floor.
Ty thought to himself "Do not know the power of my own powers... that was a little too much." as he was staring at a little girl in Mark's clothing.
"Twurn me bwack to nwormal Ty!" toddler Mark demanded her little brain confused but getting that Ty confessed that he was doing everything. Like with June reality was starting to bend to the new changes as now Mary stood in a pink frilly dress as a step-sister to Ty
"Right, a bit of aging..." Ty tried making the aging of Mary tie to the height of his hand and slowly raised it.
Mark saw his vision raise and looked down to see his dress raising. A little embarrassed Mark tried pulling the dress down to cover his panties, but that was a losing battle as now he could only get the dress to his navel. Then Mark continued to grow and grow till he could feel his hips widening and chest enlarging. Mark lifted his now C-cup boob at astonishment "Enough of this!" Mark demanded in his new voice and then Ty pushed Mark onto Ty's bed.
Ty was looking down at the 15 year old hot girl on his bed and said "No, I'll do what I want now." and smirked as the toddler dress and panties were replaced with... well nothing... in a way. Mary had been stripped of her clothes so her panties were at the foot of the bed, a Bra near the pillow, A shirt on a chair, and a skirt on the floor. Mark for sure wasn't consenting to this, but Ty had weakened Mary's body enough that her protesting flailings couldn't stop Ty from pinning her to his bed. Then there was another modification that Mary felt as soon as Ty started playing with her breasts
Mark was in euphoria. The way Ty was able to use his hands on her- HIS body just felt so good, but... Mark's mind was very mixed up with all the reality alteration as he only remembered his own change. In his mind he was senior manager at the local retail store, and had a once loving relationship with Jack... before he turned into a lazy slob that got too comfortable... So as Ty inserted his dick into Mark's vagina it wasn't being penetrated that felt wrong... It was just that everything felt AMAZING, and he knew everything about this was wrong. Mark was a man not some girl, and he had a Karen to appease instead of being appeased, and Mark was steadfast in what he knew in his conscious mind as he would deny Ty.
"More More! Rougher Bro!" Mary was squeaking out from her moans as she was somewhat subconsciously moaning. Ty grinned as Mary was no longer putting up any resistance and was really getting into this. Ty was enjoying this quite a bit as he could just use his power to not fire his load, and change Mary's body to be just what Ty wants. Ty inflated and deflated her breasts a bit and was enjoying them be around a C-cup and he just got them to the right consistency. Modify her voice to be just right... While he enjoyed a long haired Mary visually he preferred short haired Mary for having sex so he'll just change that in and out of intercourse. Ty looked out of the window and saw that the sun was setting and figured that he had fucked Mary's brains out enough and fired his load. Mary seemed to be in some Euphoric afterglow experience as whatever Mark was in her wasn't thinking very hard. Ty then found her clothes and decided to dress Mary back up and enjoying the work he did as he clothed his nice ass, her melons, and the curves of her soft skin. He then picked her up and brought her back to her room. It was a short walk, but in the hallway it was easy for Ty to hear Jack making grunting sounds... Was June deciding to try to Jack off or? Nah, there's no way she'd exercise in that body right? Ty delivered Mary to her bed in her new rather Pink and girly room, and then exited.
"What did you do to Mary Ty?" Dustin asked
Ty looked and saw the small Dustin in pajamas at the open door of his room and asked "What do you mean kiddo?"
"You made yourself bigger and me smaller, and you decide to Fuck Mary?!? Even if we're not related by blood-"
"Calm down, she was into it..." at least by the end of it Ty thought, and then he had another thought. "Well good night Dusty."
"What do you mean?" Dustin then squawked in shock as he found himself in a nightgown after Ty changed Dustin's gender on a whim. It was likely that Ty may change Dustin back... Or maybe Ty would decide to have a three-way with twins... Ty grinned in his own room as he willed himself to be ready to go to bed as he went to sleep.
