Comical Hand Job Scene with Clamshell
A playful and slightly awkward shunga from the Meiji period, showing a woman vigorously giving a hand job, while her male partner scratches his head in a mix of confusion and strain.  Her dress is loosely draped, emphasizing the casual, spur-of-the-moment feel of the encounter.
 
On the floor, a clamshell—a subtle erotic symbol in shunga—adds a cheeky visual pun, reinforcing the scene’s lighthearted tone.  Rather than purely sensual, it’s humorous and human, a reminder that erotic encounters could be as funny as they are intimate.
