Sherri had been so caught up in her lust she hadn't noticed how much she had shrunk.
As her senses returned she looked around the room and noticed that she couldn't have been more than 2 feet tall. A nearby table towered over her and her mouth fell open as she looked at its underside, completely unable to see anything sitting on top of it.
She felt an orgasmic aftershock ripple through her vagina which clenched itself on the dildo. This caused a terrible thought in Sherri's mind. Surely the dildo must have ripped her in half by now! Her head snapped down and she tried to comprehend what she saw.
Her body was not hurt, but it was strangely deformed. The dildo now filled her entire body, causing it to bulge out in a round shape. Everything below her neck was stretched out into a cylindrical shape.
"What the..." Sherri tried to speak but found it difficult to finish the sentence. Her eyes went wide as she watched her legs shrink even faster; soon they were little more than rubbery nubs sticking out of her now-enormous pussy.
No... the pussy was normal, she realized. It was the rest of her that was tiny! She'd shrunk even more in the last few seconds, her arms, boobs, and hips all melting away to nearly nothing. In fact, her skin itself seemed to be disappearing.
No... Not disappearing. Becoming translucent! Sherri started to see the dildo that was Baxter through her own skin! Every bit of her became see-through while her arms and legs disappeared entirely. Her labia went from a normal human woman's genitalia to being a perfectly circular white rubber ring circling the base of the dildo.
She swiveled her tiny head around, trying to see anyone that could help her, but the room was empty. Sherri made one last gasp as her face disappeared and her head shrunk down to be a small rubber reservoir.
Sherri had dwindled down to nothing more than a simple condom. A condom that was stretched around Baxter; the dildo that had previously given her pleasure now did nothing more than give her body a shape. Now unsupported, the dildo fell over on the floor and rolled a few feet before stopping in the middle of the room. The boy-dildo engulfed by the girl-condom; sitting and waiting for something... anything... to happen.
