What option does he go for?

Becoming a sexy twin

Well that was fun, but now it was time to do some transformation of his own for a little while.

he thought about it, while being a super stud was kind of fun it was more an end goal, right now he had a more immediate goal, knocking up and seducing all of Melanie's friends at her swanky private school. The thought of bending over and transforming all her fellow students... it was worth a little play. He snapped his fingers again and felt his body start to shift. He shrank down feeling his body blossom, tall broad shoulders compacting as a pair of small yet perky breasts bounced on his chest, his hips flared and his face feminised identically to Melanie's.

He felt his body changes switch inside to, a new womb and ovaries forming for the full experience of following her sister around John became June, her much sluttier twin, of course there was the great dilemma, were they completely identical?
