XVSR-425 - Forbidden 3-Day Stay: My Married Sister's Wild Seduction

The content is about a daughter who is proactive about sex from a subjective POV. Somehow, it feels like this girl is always like this. The development in the second half where she watches her husband having sex is fresh. The plot of 'instead of the exhausted husband, take my cock' shows off some incredible slutty (as a compliment) energy.

The plot development is a bit forced, but it's fine since you get to fully enjoy Hamasaki-san's erotic charm.
