A stepdaughter, Lisa (River Lynn) has grown into a beautiful young woman, so she needs new bras. Her helpful stepmom, Cathy (Syren De Mer), has just bought a bunch of new bras for her, and tries to give Lisa privacy as she tries them on. But when Cathy ends up accidentally catching a glimpse of Lisa trying on the first bra, she gets turned on and can't resist silently spying on Lisa as she tries on more bras! Lisa eventually realizes her naughty stepmom is watching her, so she deliberately flaunts her body even more... and then invites Cathy to have SEX with her! Well, how can Cathy resist??
