[Hazuki Kaoru] When my brother in law snuck into my bed for sex, I climaxed countless times - Chapter 1-3 [JuliusWinnfield]

Hatsumi's brother-in-law slips into her bed at night, and when she pleads that they stop here, he keeps driving into her from behind until she's sobbing through climax after climax. Wracked with shame, she runs home through the pouring rain and throws herself into desperate, sweat-drenched sex with her husband, whispering that she lied to him and giving him everything she's got to ease her guilty conscience. But when he pushes himself to come home early and calls her name from the doorway, her wide-eyed panic suggests the secret shared bed is about to collapse — three chapters of blackmail-laced netorare where every orgasm pulls her deeper.
