Wait, that aspect sounds familiar to me, I think I know her, but I don't remember the exact name of the hentai, although abbreviated it would be something like... One shota Byoutou 24-ji harem? Something like this, if I remember correctly, in that hentai, the protagonist suffers an injury and is admitted to a hospital, there, he fucks his sister, that is, the woman in front of me, his classmate, another nurse and the doctor, thus forming a harem of 4 women, interesting.
