JUTA-020 - Incest Mother-Son Affair

She goes to a hot spring with three male actors, but there's no group play. She only performs oral on the father figure, oral on one of the sons, and only has intercourse with one of them at the end. I don't see the point of having the whole family there. Also, there's way too little penetration. It would have been better to have penetration with each actor and some group scenes. The scenes of her being caressed in the hot spring while wearing lingerie and the final scene in sheer underwear were erotic, but the premise was wasted. Still, if you're a fan of Miyuki Tamura, you won't regret watching it.
