[Hazuki Kaoru] When my brother in law snuck into my bed for sex, I climaxed countless times - Chapter 1-4 [JuliusWinnfield]

Hatsumi can't fight the nights her husband's brother steals into her bed, and one surrender snowballs into secret love-hotel rendezvous and breathless daytime trysts that leave the busty married woman soaked, panting, and climaxing over and over. Every sweaty coupling unfolds under threat of discovery—an unseen peeper watches through a cracked door, and a younger relative spots the pair slipping out of a hotel together—tightening the noose around their forbidden affair. The dread finally breaks when the husband returns home early and stumbles onto the two locked in a naked embrace, his grim realization promising consequences neither lover can outrun.
