"What's going to happen to me when he pokes me in the ass with that!?"

The hot dalliance between the man with the strongest weapon (p*nis) and the man with the narrowest asshole is about to begin--!

Anayama Shigeya, who has had his first time end in failure, always breaks his partner's penis during sex due to extreme nervousness.

He is nicknamed “Kouketsu, no Tatenari” because of his narrow asshole. Fearing his narrow asshole, no one would come forward and say, “My penis is the first spear to penetrate Tatenari's asshole.

The first person to appear before the dejected Shigeya, who was told that no one would penetrate him, was Hokosaki Kirio, who prided himself on having the “strongest hardness” of any man's penis. He attacked with all his might, but his impregnable asshole was not so easily breached, and Kirio offered to challenge him again, saying, “I will definitely hold you! and offers to try again.

Will a firm ass win or a towering pole?

A BL of contradictions between a man who can't enter and one who wants to be entered unfolds!
