I came home a few days early from a business trip, and my wife was not anywhere around. But I heard some sounds coming from the bedroom, so I looked through the doorway, and spotted her on the bed. Naked. A dildo in one hand, and the Magic Wand in the other! Pummeling herself!
Whoa!
I slinked back to the living-room, tossed my clothes, and quietly went back in the bedroom.... to 'supervise'. When she finally noticed I was there, she wasn't the only one masturbating! She didn't see me, until she was cumming, but when that happened, I was cumming too....all over her tits!
Fun!
