"Hey Jen, why don't we head to the school pool." Lisa suggested as Jen asked why. "Becuase we could go in whenever we want, we can even go part doll just to float in the pool." Lisa said as Jen shrugged. "Sure why not. Not like anyone is going to notice us." Jen said as they started walking towards the school pool.
Inside the pool room it was pretty much empty as Lisa decided to remove her clothes in front of Jen, who covered her eyes.
"Relax Jen, we're both girls aren't we?" Lisa asked as Jen stopped hiding her eyes. "Let's see what I can do first." Lisa said as she dropped into the pool. Lisa floated in the water for a moment completely human and naked as Jen watched, only for Lisa's pussy to start gaining a rubber sheen and to start squeaking as Lisa rubbed her thighs together, slowly her lower body turned into rubber as her feet became foot like blobs, signifying she was a sex doll from the waist down as she floated in the pool.
"Like what you see Jen?" Lisa asked as Jen blushed. "A little..." Jen admitted as Lisa motioned her in. Slowly Jen took off her clothing before she was completely naked before stepping into the pool next to the half sex doll Lisa. "You want to do it don't you?" Lisa asked as Jen blushed. Water was flowing into her still human pussy and it was arousing her as Lisa's lower half floated on the surface. "Come on Jen, at the very least be half like me." Lisa teased her as Jen nodded.
Slowly like Lisa her pussy turned rubbery as Jen moaned before her thighs gained the same rubber sheen. "Wait..." Jen said quietly before she got on top of Lisa, her weight more then the half sex doll girl as she started pushing her down, her pussy lining up with Lisa's.
"Come on Jen, change more." Lisa said with a smile as Jen watched the rubber on Lisa travel up her navel, removing her belly button as her breasts inflated, leaving only Lisa's arms and head not a rubber sex doll.
Naked and aroused Jen let her own change continue, the rubber spreading down her legs until she had the same formless blobs for feet as Lisa, the air letting her float as her chest became inflated rubber, her breasts inflating as Lisa rubbed her rubber pussy up against Jen's.
"What now Lisa?" Jen asked as Lisa smiled.
