"Can you make me a guy?"
Ty gasped as Eileen said that. "Wait, what?"
"I wanna see what it's like!" the middle-aged woman smiled. "I've spent four decades as a woman, I think I'd like to be a man for a bit if that's OK."
Ty felt a little disappointed inside given how much attraction he'd felt to Eileen over the years, but he did want to make her happy. "OK," he replied. He closed his eyes and focused on the concept: make Mrs Paulson into a man.
Eileen's breathing quickened as her body started to reshape itself, masculine hormones suddenly becoming present inside her. "This feels so weird, but... I love it..." she whispered, shivering and shrugging off her housecoat, with a strappy top and panties being virtually the only things she had on under it.
Her muscles rippled and enlarged, her hands and feet noticeably larger after a few seconds, and her figure filled out and seemed less curvy and more firm. Her top starting to rip a bit, she pulled it off and her shrinking breasts fell from it, receding inwards until she had only pecs on a toned chest.
Meanwhile, Ty was very surprised and confused by something. He couldn't take his eyes off Eileen's increasingly masculine body. He'd assumed he would feel like he wasn't attracted to her after she started to change, but staring at her now handsome and toned chest and torso rising and falling as she breathed heavily, and hearing her deeper voice, still made him excited. The firm pectoral muscles on her chest were just as enticing to him as the big soft breasts that had been there until just now.
The transforming woman then bit her lip and grunted, looking down at her crotch and drawing Ty's eyes to it in the process. "Oh fuck, Ty," she said in her now deep baritone, "I have to get these off... I'm sorry, this might be really gross..." She slid her panties off her now thicker, firmer legs, and the two watched as the changes reached her vagina. The slit sealed itself up and her lips pressed together, and she panted and groaned as she seemed to be trying to push something out of her. An ovoid moved into her sealed skin, and after a little more exertion, a second followed. And at last her clitoris, erect from all this, started to lengthen and expand. It rapidly became many times its original size and it soon became clear what it had formed. He had a penis now.
Ty stared at the handsome, naked Brazilian man who had been Eileen, and was amazed how he felt about him. His whole life Ty had assumed he was heterosexual, or at least only attracted to women. But Eileen, or whatever he would go by as a man, was making him reconsider. At the very least, it was making his body reconsider, given that seeing Eileen develop a penis and testicles had given him a huge hard-on. Idle fantasies about sucking that big thick dark cock were swimming around his brain... and some of them were making him consider interesting options to deal with those feelings...
