Mocking his simple, stay-at-home sister and deliberately masturbating in front of her, resulting in her long-suppressed sexual desires erupting!? Breast sex and forced penetration, the ultimate sex life where the older sister completely unlocks her potential! Kitano Mina OFES-043

I always mocked my plain-looking older sister who stayed home all the time, until one day I discovered she was peeping at me masturbating. But with someone like that, I didn't need to be polite at all! Instead, I deliberately masturbated in front of her, and the result... my sister's long-suppressed sexual desire was unleashed!? She used her enormous breasts, which she would never normally show, to give me a blowjob and forcefully penetrate me! Then came forbidden, continuous ejaculation inside me! From that day on, my sister's object of desire became me...
