Wife's Secret Femdom Handjob on Hubby - Friend Chilling Next Door Has NO Clue

You subs dared me - handjob while my GF chills next door. Door WIDE open. Hubby strips, cock throbbing. I grip his slick shaft, slow twists, ball slaps and tugging. He stares at the hall, hoping she walks in. After a few mintues he shoots his warm load in my hand. She didn't catch us in the act this time, but she definitely noticed the cum-glazed hand as I passed her room heading to the bathroom.
