Rick’s heart raced as he watched Tabitha leave the room, her naked body catching his eye on the way out. He heard the toilet flush, and soon enough Tabs returned, slinking through the doorway and pausing with a sultry grin on her face.
“So...” The woman smirked. “You got your size change formula to work, huh, honey?”
Rick’s features paled, even in the dark, and he gasped. “W-Wait, I can...”
“Is it safe?” Tabitha whispered, a hint of worry in her voice as she raised her eyebrow. “Tell me you didn’t just grow me without testing it, first.”
“No, no!” Rick’s eyes widened. “Of course not! I tested it fully on the mice for the last month! I would never...”
“I didn’t think you would.” Tabitha chuckled, sliding through the door and holding out her hand, marvelling at her increased size. “Have to say, honey, it’s kind of a turn on to be big and tall like this. What am I? Half a foot taller? More?”
“I’d say a little more,” Rick whispered, his erection throbbing.
“Hmm.” Tabitha nodded, grinning. “Did you think I wouldn’t notice?”
“Maybe for a while,” Rick said playfully.
“Well, once I sat down I had to splay my legs out further. And then I noticed how everything seemed just a little smaller. I was taller in the mirror. You naughty, naughty boy. You grew me while I was sleeping, didn’t you?”
“I did,” Rick admitted, blushing.
“I would have said yes...” Tabitha giggled. “Ask a lady next time.”
“Understood, ma’am.” Rick nodded, gulping.
“Of course... at my new size... I’m going to have to punish you.” Tabitha said with a predatory edge in her voice, approaching Rick’s side of the bed, her breasts bouncing as she moved. “You made me big. So you’d better be ready to deal with that.”
“I could make you bigger...” Rick offered, gulping.
“Fully reversible?” Tabitha asked, leaning over the bed, her hands hitting the mattress.
“Of course.” Rick whispered.
“Mmm.” Tabitha smirked. “Then I’ll go as big as you’ll let me. As long as I get to have a little fun too.”
Rick brightened immediately. “R-Really?”
“Yes.” Tabitha nodded. “But first, your punishment.”
