My brother's wife Chika (30), who works as a dental assistant, has an estimated F-cup bust. With their marriage falling apart, I finally have a chance to sleep with her! Pretending to be sick, I visit the clinic and am instantly turned on by her in her uniform. Faking tooth pain, I get her to hold my hand, and when we're alone, I even manage to touch her breasts! But then I discover she's been having an affair with the clinic's director, leaving me shocked—yet this twist only drives me to pursue her even harder! In reality, sexually frustrated Chika, though pretending to resist, ends up grinding against me on her own, climaxing wildly as her big tits and huge ass shake with pleasure—an unexpected turn of events awaits!
