A pure, innocent, busty pharmacy student, while researching a new drug, is given a pleasurable drug by an experienced professor… and becomes tainted by an old, seasoned penis. Shiraha Maina EBWH-319

Huh? Shiraha-kun, what's wrong...? Are you feeling unwell? Did you inhale something bad during your research? You're very focused, so you've become enthusiastic, haven't you...? Oh dear, oh dear, oh dear, it seems different? You drank that new kind of medicine, didn't you? That's a medicine I made that makes people feel good, Shiraha-kun? Ah, no, it's leaking from my crotch! My body is getting hot too! Oh well... Shiraha-kun? I'm Shiraha-kun's supervising professor... right? I'm responsible for satisfying those beautiful big breasts and pure little mouth down there with my penis...? Come on, insert my therapeutic rod into the deepest part of your narrow space, it will feel even better, right...? Want more? Shiraha-kun? Is that so? I'll do it for you again.
