JUR-823 - “Please, just let me put it in once!” I pitied my 30-year-old virgin brother-in-law and gave in, but now we can't stop.

After losing his job and home, Yuichi moves in with his brother. His brother constantly insults him for being a 30-year-old virgin, while his sister-in-law, Yuki, feels pity for him. One day, Yuichi begs Yuki to take his virginity. She initially agrees out of pity, but the moment they connect, she's overwhelmed by an intense pleasure. Now, she's completely addicted to him, constantly seeking out unprotected sessions behind her husband's back.
