Rino Hazuki, My Amateur Researcher with Big Tits Gets Creampie

Approaching a serious, science-minded girl, she surprisingly responded enthusiastically. She's into researching penises and even collects data on her own pussy's shape, firmness, and angle—revealing an unexpectedly kinky side. The sight of a huge cock sends this nerdy girl into ecstasy as she eagerly sucks and fucks, thoroughly studying every inch. When her lab coat comes off, her unexpected G-cup breasts are revealed—so full they can easily sandwich a big dick. Her first time taking a large cock inside spreads intense pleasure deep within her pussy. Feeling it raw pushes her beyond orgasm. Ultimately, real sexual pleasure can't be understood without firsthand experience!
