>>57422188Pretty much, guy gets sent to Hisui for his sex pest isekai assignment. Shows up at night and the first person he meets is Vessa, who can tell he's special and tries to approach him like she does the protagonist. Bam, he whips his cock out and shoves her face in it and crams her down his dick faster than she can react. He finds an empty house and spends the night their with her trapped in one of his balls and he wakes up the next morning surprised that she's still alive.
It was going to lead into him having to find all the scattered wisps with his dick being a new odd keystone, absorbing each of the souls into his cock before finally Vessa transforms into a spiritomb gijinka that's bound to his dick but I never got that far.
