While engrossed in a lively chat, mature Japanese beauty Miki Uemura feels an unexpected buzz against her thigh. Her step-son, Nobuka, has snuck up behind her, pressing a vibrator against her stocking-clad leg. Miki, in her sexy lingerie and fuck-me heels, tries to suppress her moans, but Nobuka's skilled teasing soon has her dripping. He switches to cunnilingus, lapping at her shaved pussy, before flipping her into doggystyle and fingering her gaping asshole. Miki can't help but reach back, guiding his cock into her tight, wet slit.
