Yari☆Chin Shirou!

Shirou, a young man living in an apartment building, engages in sexual encounters with multiple women. He begins by having sex with his neighbor through a hole in the wall before meeting his girlfriend Nanako at a love hotel to have sex in the bath. Later, Shirou meets another woman named Mineko at a different hotel for further sexual activities. He then visits Misae Nohara, and the two have sex in various locations around her house, including the bathroom and against a glass door. The encounters conclude when Hiroshi and Shinnosuke Nohara return home, prompting Shirou to casually join the family for a meal.
