she felt the warmth focus on her ass cheeks. Soon the warmth turned into pleasure as her ass slowly grew. She leaned against the wall to steady herself as she got more aroused. She looked back and could see her ass was twice it's original size! But her cheeks originally did hang a lil having a slightly odd shape when she wore bikinis and such. She felt her hips get warmer and they started to shift too, widening with each breath she took.
"Oh my god..jake..this...it's so big..." she said.
"Umm...do you want it to stop?"he replied
"No..just let...it finish.." she said eyes closed.
He saw her arms against the wall,head down, while her legs were spread. He wanted to have sex with her already seeing her this way. She already was pretty cute but now she was fucking hot and getting hotter. He saw her ass widen and become more bubble shaped. Once her cheeks were really pushing against each other they stopped growing. She was panting hard and still didn't move.

"That...was..."
"Good?bad?tell me love"
"Amazing! "And now I have a great ass.ahhhhmmm"she moaned as she slapped her ass. She didn't know how sensitive it would become.
"Wow...I didn't know it would feel better too. So jake...what do we do now?"
Jake noticing her hint tried to think of a good response.
"Well did you want to keep experimenting?"he said with a smirk.
"I want to experiment with you!"she said as she lunged for him.
Both of them never having sex before took a bit for him to take his clothes off. Even though she was his to command he was still nervous and treated her the same. They started making out but after a bit she noticed his hesitancy.
"Jake it's okay we can take it slow. How about you choose another change and you can watch up close with me". she didn't even realize how horny she was.
"Okay Jenny I-"
