Yumeka, a smart but loose science girl, makes her debut! Yumeka is a serious, gentle, big-breasted beauty who studies biology at the university's Faculty of Science and Engineering. She has had sex with six people and is popular at university. She loves cock and blowjobs as much as she loves research, and says with sparkling eyes, "I appeared in an adult video because I wanted to suck all kinds of cocks!" Her charm is full of her sucking and not letting go of the cock even after ejaculation!
