Before she'd been turned into a lacy pair of panties, Kyle had told her that she would be able to communicate with whoever was using her, even if she didn't have a mouth. So far, Jenny had refrained from doing so - what exactly were you supposed to say in a situation like this that would help anything and not make it incredibly awkward?
Hey Valerie, sis, you know those lacy panties you put on that made you wetter than a fire hose? Surprise! Those panties are me, your sister!
It was going to be awkward enough when she transformed back in a couple hours - though she wasn't really sure how long it had already been. It was, understandably, hard to keep track of time when you were a piece of clothing.
But when Penny leaned down, her attractive face inches from Jenny's lacy form with a lusty smile on her face, and began stroking at Valerie's increasingly wet pussy through the panties she had become, Jenny couldn't help but moan from the sensations. She wasn't sure if Valerie had heard it or not - since her sister was also moaning, it was entirely possible it had gone unnoticed. The harder Jenny stroked, the more incredible Jenny felt - it was like a full body sensual massage. Was it even possible to have an orgasm like this? It certainly felt like she was experiencing one after another.
Eventually, wanting more, Penny pulled Jenny down, where she fell to the floor, discarded and forgotten by the two lusty lovers. Valerie and Penny proceeded to undress, their breathing growing more intense as the two girls fingered each other. Jenny could only watch from the floor, numb from the pleasure she'd experienced when Penny had been stroking her.
And then a peculiar sensation washed over her.
Oh shit! Jenny thought.
The time was up.
In moments, she felt her body begin to expand and grow, skin replacing lace as she reappeared, her naked form suddenly pressed between the equally naked form of her sister and Penny.
For a moment, Valerie and Penny stared at her in shock and silence - the only noise was from Jenny, who was shaking slightly, teeth chattering from the sensations of the change.
Then Penny screamed and leaped back, covering her sizable chest, for all the good it did - Jenny had already seen it all. Valerie looked incensed. "JENNY?!" she demanded. "What the FUCK are you doing here? HOW did you even--?!"
"V-Valerie!" Jenny stammered. It was hard to focus in a room that smelled so much like sex. After being stroked like that, Jenny found that she was incredibly horny. Being in the middle of Valerie and Penny in the somewhat cramped closet was making it really hard to focus on speaking when all she wanted to do was fuck them senseless. "I-I can...I can explain...!"
"J-Jenny?" Penny said incredulously. "You just came out of nowhere..." She was still covering her breasts with her hands, but she no longer looked as startled. Her eyes trailed up and down Jenny's body, who flushed with embarrassment. Penny bit her lip slightly, her arousal still apparent despite her own modesty.
