Riko enjoys inserting fingers into her anus during masturbation. However, she suffers from constipation and struggles to fully relieve herself. Recently, even enemas have become ineffective, causing feces to accumulate further. To thoroughly clean Riko's intestines, a special care session is arranged. With her shaved, bare pussy fully exposed, repeated careful enemas are administered until, eventually, an unfinished, vomit-like feces begins to emerge from her body.
