MTL Summary
Suzu, an ordinary office worker, is asked by her relatives in Kyoto to take care of their cat and spends a week in an old house.
That night, as she falls asleep, a ghost appears in front of her and starts to play with her nipples. Suzu can't stop moaning as her nipples are stimulated more and more intensely. She wakes up in the middle of the night, but she is paralyzed and can't escape.

A wet, cold tongue wraps around her nipples, licking and flicking them from the base to the tip. Suzu can only feel the sweet moans of the wet, cold tongue as it licks and flicks them, even though it's scary. The inhuman stimulation of countless tongues crawling around her nipples makes her cum just from her nipples.
The next day, Suzu is relieved that the previous night's events were just a dream, but the ghost appears every night from that night onwards,
licking and sucking her nipples and clit, and slurping them.
No matter how many times Suzu cums and loses consciousness, the ghost's tongue continues to move relentlessly, and the never-ending stimulation continues endlessly.
With each passing night, the spirit's caresses escalate, and Suzu, who was initially frightened, gradually loses her reason due to the overwhelming pleasure.

The next day, she notices that the video has been recorded on her pet camera and plays it back, realizing that everything she had seen with the spirit that she had thought was a dream was actually real. However, when the ghost appears again, she spreads her legs and invites him to "make me feel even better..."
Then the spirit, which had not been seen until then, appears...?!
