Looking for a doujin called 性春マゾヒズム (sexual masochism) by 九反 (Kutan) that was released around February for COMITIA151. Can't find much info aside from that it was released as part of a bundle with another doujin of the same name, by 白丸 (Shiromaru), and included some additional shorts featuring the character.
Managed to dig up some links that seemed to lead to the digital copy, but they're either dead or region-locked
