She's smart but laid-back, and the science girl Yumeka-chan is making her debut! Yumeka-chan studies biology in the engineering department at university. She's a serious and gentle big-breasted beauty. She has had H experiences with six people and is apparently popular at university. It seems she loves penises and fellatio just as much as her research, saying, 'I just want to suck all kinds of cocks, so I'm appearing in an AV!' Her charm is fully loaded as she sucks relentlessly even after ejaculation!
