Alex's niece had come to stay with him. She was in college and just looking to "do things a little different" during the summer break. Alex lived in a beach town with a bit of a party scene, so he figured that meant she was probably try to get away from her parent's scrutiny for a bit. Alex told his sister he'd keep an eye on her.
Unfortunately for Alex, Julie took more after her father. Particularly, she'd inherited her father's magic.
The first thing she did when she got to Alex's house was to transform him into a woman, and not just a woman, but she'd zapped him to be the same age as her! With a flash from her eyes he went from a man pushing fifty to a woman who wasn't even twenty!
Alex protested and threatened to call his brother-in-law, but Julie just laughed and said that the magic made it so Alex couldn't talk about who he really was to anybody but her. She told Alex to relax, that this wasn't a punishment. She'd always thought of Alex as her "cool uncle", but she'd also always wished she'd had a "cool cousin" to hang out with. Since Alex never had kids, she'd decided she'd just make him her cool cousin for the summer.
It felt strange to be so young again, but obviously being a woman was far stranger. Alex complained about his new sex and Julie just laughed, saying she'd put a spell on him that ought to kick in when he went to bed which would convince him being a young woman could be fun.
Alex didn't know what that meant, but didn't really have any other choice than to play along as Julie marched into his room and started transforming all his clothes into girl clothes, then made him put on a fashion show for her. When he was finally ready to go to bed, he suddenly felt an intense desire and his hands started moving on autopilot, groping his new tits and fingering his new pussy. He groaned, stunned at how good it felt as he hastily pushed himself to an orgasm. His hands didn't stop moving though, and he found himself seamlessly continuing into more masturbation. He barely got any sleep that night, but he did cum eight times.
======
It soon became clear to Alex that Julie hadn't just done this to him because she wanted to hang out with her "cool cousin" that summer, but because she was trying to get away from his supervision. She went out to parties every night. Alex knew he should go and keep an eye on her, but he was busy getting comfortable with the fact that he had boobs and needed to sit to pee now. When Julie decided to host a party at their place though, Alex had no choice but to attend and try and keep an eye on her.
That was how Alex met Hugh. Hugh was just a fairly unremarkable young man, except for one thing: Hugh's best friend was the super hot Damien who Julie was really into.
When Alex tried to get between Julie and Damien when they started getting hot and heavy at a party, Julie flashed her eyes at Alex and when he looked over at Hugh his heart began to race. His palms got sweating and his throat got dry and his pussy got wet. Hugh had been catching Alex's eyes and glancing at him all night, but now when he did it, Alex blushed.
Alex was a riot of emotions when Hugh started talking to him. He was so glad Hugh was talking to him. Screw Damien's unabashed hotness - Hugh was the real catch! Smart, charming, funny - if Alex had met Hugh when he was in college they totally would have been buddies. And Hugh was cute.
Alex knew it was all wrong - or at least, not natural. He was pretty mad at Julie. She'd turned him into a young woman so they could "hang out more naturally" - fine, it was weird, but fine - this though!? She'd cast a spell to make Alex have a crush on Hugh just so he wouldn't bother her!
Alex and Hugh's chatting became flirting and Alex found himself all tongue-tied and flustered and excited! He was so nervous! Fortunately for Julie's plan, Hugh found Alex's confundity rather cute and kissed her to keep her from continuing to stumble over words.
Alex's heart was in his throat. It was like fireworks when Hugh kissed him. He kissed back passionately, sure it was the best kiss he'd had in decades - maybe ever.
Kissing became pawing, became petting. Alex was so worked up, when Hugh asked ehre Alex's bedroom was, he immediately told him. Alex's conscious brain barely working, he only barely remembered Julie as Hugh led him away. Looking back, Julie and Damien were making out pretty hard, but still on the couch. Apparently Alex and Hugh had passed them at some point.
Alex didn't have much time to think about that though, because next thing he knew he was in a bedroom with Hugh's dick in his hand.
Looking down at it, Alex couldn't help but notice how spectacular his cleavage looked and how hard his nipples were hard. His pussy pulsed with warmth and it struck him suddenly how that body was his, and far from being repulsed by the warm dick in his hand, he wanted it shoved inside of him.
"Wow." Alex said, more about the whole situation that the dick.
Hugh just took the remark as a compliment as Alex stripped and climbed ontop of him.
Alex couldn't believe it. Bouncing his pussy on a dick was literally the greatest sensation he'd ever experienced. He couldn't contain himself. He moaned and squeaked and squealled. After two breath-stealing orgasms, Hugh's cock twitched and fired inside him triggering a third, world-ending orgasm. Alex muttered an awkward thank you, but couldn't keep his eyes open anymore after that and passed right out.
======
The next morning Alex awoke alone. There was a note on the pillow beside him from Hugh thanking Alex for a great night.
Alex sat up, feeling his hair brush his naked shoulders, his tits hang, and his pussy empty. Fidgeting with his hair in the light of dawn, he considered the previous night's activities with sober clarity.
Alex had really enjoyed that! Thinking about Hugh made his heart start to race again, and his pussy twitched greedily. He wanted to fuck Hugh again, but also more than that. He wanted to spend time with Hugh. He wanted to make Hugh happy. He wanted to satisfy Hugh. Unprompted, he was thinking about whether Hugh would like a blowjob. Obviously he would, Alex realized a second later.
"Damn it Julie." Alex muttered, realizing just how much beyond a physical transformation his niece had done to him.
Alex was a young woman, and she wanted Hugh to be her boyfriend.
It was going to be a long and interesting summer as Julie's cool, sexy cousin.
