Alice saw in the book that Aiden's attraction was different than hers so she decided to change herself into a boy who was his age...and wrote that Aiden would be aware of the changes and both of them would be nude as the changes happened as Aiden would want them to, but they would be the only ones who knew.
"Woah!" Aiden exclaimed as the two's clothes vanished and Alice's hair became short and blonde and her frame became a boy's. "Now get a frame similar to mine."
"This is a much stronger build." Alice noted with her new boy proportions and voice. "What's next?"
"Your butt will become as bubbly as mine and you will have a surfer's tan and six pack like i do since we both go surfing regularly as we live by the beach." Aiden remarked getting harder as his changes occurred.
"I'm almost a full boy, now!" Alice exclaims as she moaned in pleasure at having a boy's features "Whenever you're ready."
"Then you will be known as Andy after you grow a penis in place of your vagina." Aiden replied with the final change happening as he patted the new boy's butt the second that Andy came. "We're also exclusively an item and will enjoy having fun with each other."
"Oh wow, being a boy sure feels nice." Andy said as he kissed Aiden who returned the favor and began sucking his member and groping his butt.
"Oh that's so good!" Andy moaned before doing the same to Aiden.
"Of course it does, now put your member in my butt, please." Aiden asked.
"As you wish." Andy agrees with the two taking turns doing so until they came and kissed more.
