As best she can

Gina could barely breath. The pleasure she was experiencing from having her hypersensitive sex button yanked had almost made her fall ****. The only thing keeping her awake was the stimulation itself.

“I-it’s my... clit.” Gina panted out. Her face was beet red, and a long strand of drool was hanging from her mouth. Susan just looked dumbstruck.

“Has it... always been that big?” Susan asked.

“Obviously not dumba-AAHH!” Gina cried out, her comment adding another inch. Susan went big eyed and took a big step backwards.

“Did it just grow?!” She asked, becoming increasingly more concerned. Gina opened her mouth to speak, before closing it again. She had just cum, and already this thing had her on the edge. Using what little willpower she had left she answered.

“It grows any time I do something mean.” Gina said, pausing to catch her breath. “And it shrinks when I’m nice.”

Susan just kept looking at it, almost hypnotized by its size. After a few moments she giggled.

“Wow Gina, you must really be an asshole if you let it get this big.” She said.

What Gina wanted to say was that it was Susan’s fault for being too stupid to let her be nice to her, but thought better of it. Instead she just replied...

“T-that’s why I need you to ask me for favors, so I can go back to normal.” Gina hoped that explaining things to Susan would speed things along.
