When her husband asked her, "Hasn't your vaginan tightness gotten worse recently?", his wife, Kokone, decided to work on improving her vaginal pressure. Meanwhile, her father-in-law, a former chiropractor, decided to teach her vaginal training... After repeated unnecessary close contacts and persistent touching, their genitals became tightly pressed together! She kissed him secretly from her husband, gave him sticky cunnilingus and a careful blowjob when she found an opportunity, and then had raw sex at night! Her tighter pussy squeezed her father-in-law's dick tightly! She hugged him tightly and had a creampie, completing the happy pussy!
