GVG-472 - The forbidden desire of a son-in-law for his busty mother-in-law

The transition from maternal devotion to pure lust the moment she sees her son-in-law's member is incredibly erotic! I just wish the initial requested fellatio had been a bit more intense. Also, I really wanted to see an internal ejaculation during the first act.

There's a scene where she only swallows half after a paizuri climax in her mouth. It's a scene you rarely see in other works, so I'm giving it 5 stars.
