Erica grabs Lisa’s hand and stuffs it down her pants

(Chapter originally by c1ph4r on writing.com)

Why wasn't important, Erica decided. Seeing an opportunity to get even with Lisa for all the horrible experiences over the years, and with Lisa distracted with driving and shock with suddenly being topless, Erica made her move.

With her left hand, Erica grabbed Lisa's right. The sudden movement alerted Lisa that something was happening, but it was too late. Erica pushed Lisa's hand down into her pants, where they rubbed against her clit through her panties and caused her pussy to moisten.

Lisa yelled in protest, even as her pants exploded. Unbeknownst to either of them, the more times that Erica's mom's device was triggered, the stronger the reaction. Cloth went flying everywhere, like confetti.

Seeing Lisa only dressed in her panties, was too much for Erica. She could feel herself gushing in anticipation of this total ****, so she started masturbating herself with Lisa's hand.
