This Isn't Cheating

Kimmy moaned and gasped as she felt her step father's cock brush against her pussy. They were alone in the house while her mother was out for work. Kimmy's step father told her her needed a little stress relief before sliding his cock between her legs.

"Should we be doing this. Aren't you cheating on mom?" Kimmy asked naively as he fucked her thighs

"Of course not Kimmy. It's only cheating if there's penetration. All your doing is being a good step daughter helping me relax after a stressful day at work."

The naive Kimmy accepted her step father's reasoning. Which caused him to wonder what else he could talk her into.
