A cool/handsome and a silly/easy-going guy team up for super-sensitive nipple training!
“Why don’t you train your nipples?”
High school student Yota was dumped by his girlfriend, who found his sensitive nipples revolting.
At this rate, he'll never have a girlfriend...
To overcome this crisis, Yota asks his incredibly popular childhood friend Ryo, who always seems to have a girlfriend, how to desensitize his peaks.
Ryo then suggests that he train… his nipples?!
