[Shiro] A warrior summoned from another world...

A lonely office worker chalks a summoning circle on a rooftop as a joke—only to pull Alfredo, a hulking armored warrior, straight out of a cursed fantasy realm where breaking the Demon Lord's spell demands lewd acts between men. What starts as the warrior's desperate quest to return home melts into sweat-drenched worship of his summoner's body, from an eager first blowjob to a raw first time that leaves the narrator utterly ruined for anyone else. Days blur as Alfredo keeps holding his new lover, the curse quietly forgotten in favor of addiction to each other—and neither one is complaining.
