Xander Corvus sister-in-law, Dee Williams, is visiting for the weekend, and things get off to a rough start when Xander walks in on her masturbating in the shower. Although Xander avoids detection, his wife is immediately thrown off by Dee ripping down the shower curtain to cover herself. Feeling guilty, Dee finds her sister in the laundry room and offers to take over in order to make amends, but a sneaky Xander, after catching a glimpse of Dee bent over in front of the washer, decides to make a shockingly direct and assertive move.
