Hi /r/
Looking for an hentai manga. It was a 30-ish page story, uploaded on sadpanda (in english).
It was set in a school in a fantasy world. The protagonist (GirlA) was in love with boy. There's a hot transfer student (GirlB) and GirlA is jealous so she goes to a forest to get an aphrodisiac to make the boy fall in love with her, but she is attacked and tentacle raped/mindbroken by a creature. In the end GirlB goes to the forest and finds GirlA having sex with the creature.
