FERA-163 "Do you like old ladies like your mom?" If she finds out I've been watching mature AV, she'll say I once came inside my mom. Honma Yuri.

Yuri peeked at the collection of DVDs in her son's room. She had only intended to check out his masturbation material as a prank, but what she found were numerous works featuring actresses around her own age. While feeling awkward about learning her son's fetish, Yuri also felt a stronger urge to play another trick. If he likes older women, maybe he'll get excited over my body too... Unaware that this would be the start of opening a forbidden door, Yuri charged into the bathroom while her son was taking a bath.
