[Bitch Goigostar] Wife Writhing in Madder Ch. 1-8 {Doujins.com}

Eight linked chapters trace married women whose quiet domestic routines collapse into secret lust, each wife pulled deeper until she's writhing in the title's madder shade. A busty gym teacher sweats through her PE clothes as Iwabuchi corners her after years apart, teasing that her huge tits show right through the damp fabric, while housewife Manami sends her hungover husband Yukio off to work with no idea what her day becomes. Elsewhere the poised Nanao, recognized on a rainy street as a debt-ridden company president's wife, finds an old acquaintance has been looking for her, and the stories braid into shibari restraints, swinging arrangements, and filmed group sessions where every wife learns how far she'll go.
