DVAJ-718 A senior of unknown age who lives in the club room of my university club offers to lend me

Kaoru-senpai has taken up residence in the club room of the club I joined. She sleeps over without permission and never seems to attend lectures. She's also a total idiot, having repeated a year so many times that no one knows what year she's in. We somehow get along well, and I secretly enjoy seeing her unprotected cleavage and glimpses of her underwear... Then, as we started talking about sex, she openly asked me if I was still a virgin and asked if I'd like to have sex...
