Father-in-law replaces son with erectile dysfunction to "take care" of daughter-in-law

Ichika lives with her husband and father-in-law. Her father-in-law is very rude, always gossiping and speaking ill of her. Despite telling her husband many times, he still hopes she can endure and try to reconcile with his father. Now Ichika understands why her mother-in-law had to leave. Her husband is about to go on a business trip, and she hopes that before he leaves, they can be intimate with each other. But because of erectile dysfunction, her husband is helpless. Not being able to have sex for a long time makes Ichika's body feel uncomfortable, craving sexual desire. Her father-in-law also knows about both of their situations, especially knowing that his daughter-in-law is not satisfied.

When their son is away, he touches Ichika's body while she is asleep. When she wakes up, Ichika discovers her father-in-law is touching her vagina. She wants to stop him, but her body has no strength. With his experience, her father-in-law quickly makes Ichika climax again and again. When he takes out his huge erect penis, Ichika can't think anymore. She stares at it, and her body instinctively moves to suck it. She wants to be fucked, by the man she hates the most! And from then on, Ichika only wishes for her husband to be away so she can have sex with her father-in-law all day long...
