[Yoku no Genzen (Tarenagashi)] Why Did You Go with That Guy...? + Valentine's Day [Navajodo]

A blackmailed mother tells herself she's sleeping with a pushy, muscular delinquent purely to protect her son Masato—right up until she's riding him in sweat-soaked ahegao bliss, admitting she now looks forward to every tryst and begs him to creampie her on the first shot. Under threat of rumors being spread with no evidence, her reluctant sacrifice curdles into eager addiction as she worships his cock musk, deepthroats him with rolling eyes, and takes load after load while musing that 'auntie's pussy still has some use to it.' A tight netorare corruption arc where 'it was for Masato's sake' gives way to raw, trembling surrender at the hands of the very man ruining her.
