Theresa sank a hand in, gripping and squeezing greedily. She shook her hips ever-so-slightly, rewarding herself with a cascade of unceasing jiggles. She gave herself one sharp spank and then felt her eyes roll back, involuntarily, as sensation washed over her. “Nobody told me it felt this good,” she groaned, her skimpy little bodysuit straining as she swelled out just a touch further. “I mean, they said it was good, but like…” She sank her hand in again, her fingers squeezing soft, fat flesh. “…That kind of, nnnnnnnngh, undersells it.”

She rolled over onto her front, her hips quaking almost without her thinking about it now as she grew and swelled further and further. Her skirt rolled up to her hips, her panties a mostly-hidden afterthought now. She flexed her thighs together, feeling the slight gush of her pussy, on fire as the sensation continued to flow through her fattening ass. “Really good, really, really good,” she moaned, her panties snapping as she pushed her ass back. Trying to hold it still in the air, she found she couldn’t, her legs were quivering from pleasure and the unfamiliar weight, her body constantly shaking, causing the pleasure to extend and heighten, with no crescendo in sight. “Really…” She breathed out, and then came, her thighs suddenly wet, her body shaking and jiggling as she continued to grow.
