[Kai Hiroyuki] Mother's Sex Lesson Ch. 3-4,7 [biribiri]

A blizzard strands a lonely married beauty on a ski trip with a young boy, and years of a cold marriage melt fast once she discovers what he's been hiding under his winter gear. Hayami-san can't resist comparing him to her husband—and he wins every round—as her eager mouth, heavy chest, and insatiable body teach the stunned boy just how hungry a neglected woman can get. A closing chapter shifts to comedy as busty Yamamoto-san sends Yuuya crawling into the storeroom gap after her lost earring, only to wedge herself hopelessly stuck.
