Yukiko Ishihara is a schoolteacher who has resolved to live as a male sex slave. As proof of her submission, she has been pierced with a nose ring like that of a domesticated cow, which she conceals with a mask while teaching her students every day. Initially small, her nostrils have now been stretched to such an extent that they can support a hanging padlock.
This body modification extends beyond the nose ring. Piercings have been placed on her labia, from which nearly one kilogram of steel sexual apparatus hangs, training her labia to stretch further. Her nipples have undergone similar enlargement and elongation, now reaching the size of an infant's penis.
Her anal training remains ongoing, though she has already achieved AF (anal fitting). Future sessions will involve even thicker implements for further stretching. Additionally, padlocks are attached to her labial piercings, the keys to which are held exclusively by her master.
The video documents her daily training routines as well as gangbang scenes with invited guests. A special bonus slide show of photographs sent along with the video is also included.
