Happypink - The Alcummy of Amelie Final (eng) - Adult Sex Game

Amelie is a buxom girl who lives in Gardenheim.
One day she's falsely accused of a crime and sent to jail,
where she gets to know a succubus named Sully.
Sully curses Amelie with a thirst for sperm that she'll only take back
once Amelie fulfills Sully's training and alchemy request.
Looks like they're partnered together for a while...
