It was a pretty short piece I read a while ago. A teacher catches students in a sex club at school. She acts kinda indignant but forced/cajoled into joining in. During penetration she's like "no, if you have sex with me I'll fall in love with you!" The (faceless?) guy replies "Don't you have it mixed up? You're pretty cute teacher". And so she falls for him.

Art was pretty cutesy.

Does anyone recognize this hentai? Thanks 🙂
