JUX-254 Cuckolded Sister-in-law ~ I'll do it instead of my brother! ~ Yui Hatano

It's been 3 years since we got married. Yui, a wife, diligently takes care of her husband, who has fallen ill due to a sudden illness. Her brother-in-law Koji, who has a secret admiration for Yui, also worries about the fate of the two, but can't do anything about it... One day, when Koji visits as usual, he encounters Yui processing her brother's sexual desires. Koji secretly peeks at him as if fascinated. Moreover, I feel lonely because I can't have sex with my husband.
