Boys who can't help but worry about Nobra's mother-in-law, Kana, at home. After his father's remarriage, the brothers wanted to get along with Kana, who was beautiful and kind, but the relationship continued to be jerky. It was at the moment when Kana noticed the abnormal hot gaze of the breaths staring at her chest that the stalemate between mother and child collapsed. "... Are you interested?" Kana, who doesn't want to quarrel with her breathes, proposes to expose her breasts in front of her sons and touch them freely, provided that they are only a little. "Are you really okay?" The boys swallowing raw spit. At this time, Kana will receive 1,000 yen worth of free points for the first time!
