Wait for their moment

Tim and Jacob found out a few things while gym took place, they could adjust her suit size for one, which they took advantage of several times when she dove, but immediately fixed the suit back to her before she could take notice. They could turn themselves and others invisible, after a quick test of Jacob being able to slap Renee's ass without her noticing. There was a lot these devices could do and with this power the nerds started to feel like entities that could control anything.

"Alright everyone, time to go change back into your school uniforms." The teacher bellowed as everyone began to head out of the pool and towards the exit of the building that lead to the trail leading back to the school. That is everyone, expect Renee who was still underwater attempting to beat her record for longest breath held, no one had seen her as Tim had put her under the cloak mode they had discovered. The boys also unconcealed the senior female, still unaware she was the only one in the pool. As the last student and faculty member left the building thinking no one was around, Tim and Jacob knew this was their moment, pressing the button one more time.

Renee felt a rush over her body, as a strong chill enveloped her being, quickly making her surface for air, coughing violently. After finally being able to breathe normally, she looked around seeing no one, and from the bottom of her eye, she noticed two bright white fleshy bits bobbing up. Looking further down, she was greeted to her pink nipples at attention, and the rest of her physically fit body.

Renee covered her mouth spinning around to make sure no one was around, letting out a sigh of relief. However, the grief washed over her again as she realized that while she did have clothes back at the school, she would have to walk the trail, and enter the main building as is.

Renee looked again one more time as she climbed out of the pool on the sides of the bleachers. Where Tim was taking photos of her leaving the pool, Jacob was recording video of her swinging tits, and very bare crotch.

She brought her hands down to her mound using her arms to cover what they could of her breasts as the passing bell shook Renee's nerves. She would have to get to the locker room hall within the next ten minutes, and the pool building was at least a 5 minute walk.

She left the building as the boys followed closely, Tim laughing to Jacob.

"Learning bout anatomy is fun..."
