Sericulture Chamber, No. 10 from the book Elegant Erotic Mane'emon (Fūryū enshoku Mane'emon), vol. 1

Mane'emon hides beneath silk worm trays in a farmer's house as a young husband pushes his wife to the floor for a hasty encounter because he is aroused by the Azuma nishiki-e ('brocade pictures from the Eastern capital, ’ probably shunga) which his brother brought back as a souvenir from Edo.
