My sister-in-law's lewd butt makes me want to devour it

Natsume, a wife who has been married for two years, is living a happy life with her kind, hard-working husband, Ginji, who loves butts. One night, Ginji came home with his younger brother, Shinji. Apparently he was looking for a job, so I decided to live with him until he found a job. Shinji, who loves butts as much as his brother, can't help but be curious about Natsume's butt. The best peach butt you've ever had in your life is within reach! Just thinking about that made my head fill with thoughts about Natsume's butt...
