[frontierkiss (Kai Makoto)] Hateshinaki Sacrifice Zenpen (24a)

A mountain of sweat-slicked muscle gives up his own body to spare another man, falling into the hands of a heavyset, bearded master who knows exactly how to break a strong-willed captive. Harnessed and gagged, the hero is made to swing a bell tied to his throbbing cock, then strapped spread-eagle to a bondage rack where merciless tickling and nipple torment rewire his whole body into one desperate erogenous zone. By the end he's addressing his captor as Master and begging for the training to continue, hailed as a hero for his endless sacrifice — and this is only the first part.
