MFYD-125 — Newcomer Biology Researcher, Jun Shiraishi (30 Years Old), Makes Her Av Debut. She's Usually Intellectual, But The Contrast With How She Becomes Like An Animal When A Cock Is Inside Her Is Incredible.

A married woman with an astonishing gap between her "intelligence" and "instinct." Jun Shiraishi (30 years old). Now a biology researcher, she's a high-achieving married woman involved in clinical trials and development of new drugs. However, instead of the "herbivorous" sex of her husband, who works at the same research institute, she craved intense sex and stepped into the world of adult videos. When she undresses, she reveals a surprisingly slender body with F-cup breasts and a plump, sexy bottom. And when a penis is inserted, her moans and orgasms become animalistic and screaming, the complete opposite of her usual quiet and intellectual way of speaking. A married woman with an astonishing gap between her body and her sex drive makes a shocking debut.
