I Thot You Was a Toad's manga / #Hakutou Noriko(3)

The cover illustration may lead you to believe this is a collection of stories about men getting kicked in the nuts. Chapter 4 implies that this means figuratively ... so far.

First sex ends up as a dud for a couple of friends from high school, which means sex is banned ... except the seme is willing even to train for a marathon to win back the chance.
