Gensokyo Constipation Incident ~Izayoi Sakuya~

Izayoi Sakuya comes to Eirin with a large, bloated, constipated belly. Eirin, who has a malicious sadistic fetish,
while treating her, decides to torture the Scarlet Devil Mansion maid by recording her, giving her an enema, and, ultimately, making her sit on the potty to hold it in.
