MOND-129 - Umanami no ani ni mero mero ni sareta otoutoyome Konishi Yuu

Until now, she had never been to her husband's family home, but this time they visited together. Her brother-in-law was there, and his arrogant, money-flaunting attitude left Yuu feeling unimpressed. Hearing from her husband that he had never been with a woman due to his personality made her feel a bit better. The next morning, Yuu was flustered to see her brother-in-law in his underwear. He’s an unpleasant man, but his 'member' is huge. She has no complaints about her husband, but after seeing that—and thinking he might be a virgin—Yuu starts having lewd fantasies about what it would be like to taste it, take it inside, or steal his virginity.
