Reposting the second volume of this series. Now the wife (who still has no name) has fully embraced her relationship with her son, Yuu. Today, they go to the grocery store and end up having sex in the bathroom. And it just so happens that Yuu’s friend, who they met in the store, goes into the stall next to them to fap to Yuu’s mother. That would be an awkward situation under normal circumstances. Well… Fucking your own mother isn’t a “normal” circumstance, so scratch that thought… In any case, enjoy!
