EBWH-319 A pure-white, big-breasted pharmaceutical student got a pimple from an old professor's disgusting drug while researching a new drug... and has become stained with an old penis. Maina Shiraha

Oh??? Shiraha-kun, what's wrong...? ? Are you feeling unwell? ? Did you inhale something bad while doing your research? You're such a serious person, so you got carried away...? ? Oh my, my, that's not it? You took that new drug, didn't you? That's a drug I made that makes you feel good, Shiraha-kun? Oh no, that's bad, you're leaking juices from between your legs, aren't you? Your body's getting hot too, isn't it? I can't help it... Shiraha-kun? I'm your professor, Shiraha-kun, after all...right? I'll take responsibility and satisfy those beautiful big tits and that innocent-looking lower mouth of yours with my dick...? See, now that I've inserted my treatment rod deep into that tight spot, it feels even better, doesn't it...? Do you want more, Shiraha-kun? Really? I'll do more.
