[Kai Hiroyuki] Mother's Sex Lesson Ch.3 [biribiri]

Stranded on a snowbound mountain after wandering off the ski slopes, a shivering young man finds salvation at a remote inn where the voluptuous innkeeper knows exactly how to chase away the cold. She coaxes him into the steaming open-air bath, wrapping him in the overwhelming softness of her enormous bust with slow, drooling paizuri before riding him through the water until he empties himself deep inside her. Even after the blizzard clears and rescuers arrive, the innkeeper is still taking her time with her grateful guest, coaxing him toward one more warm round.
