Mom comes in

Jemma was still busily fellating him when their mother walked in, a terry cloth robe over her night gown. The busty 44 year old froze, her green eyes wide, her mouth agape.

"Jemma!" she cried at last. "What are you doing?"

Josh's sister pulled his cock out of her mouth to look guilelessly up at her mother and say "I like it! He told me so!" and then resume her task with thoughtless determination.

"Oh God!" Ronnie exclaimed, shedding her bathrobe and letting it drop to the floor. "Oh God Oh God Oh God No! Not you! Not you too!"

"What are you doing Mom?" Josh asked, confused. Something about his mother's response to what he had done to Jemma seemed...off. His eyebrows raised as Ronnie hurriedly pulled off her panties. Josh imagined he would have had her do that eventually anyway, but he hadn't said anything to her yet!

A look of relief washed over Ronnie as she took her right thumb and stuck it in her ass. Then she looked defiantly at Josh.

"Ha! You didn't know I could do THAT did you?" she exclaimed. "I didn't spend all those years as your father's fucktoy without learning a trick or two of my own! You're power won't work on me with my thumb up my ass!"

This was all coming a bit too fast (while he was coming in Genna's mouth a bit too slow). Josh's long-gone father had the power too? And a thumb up the ass really blocked it? That didn't sound right, did it?
