SPRD-061 - Caught in the Act: The Widow and Her Shut-in Son

I really love this series and own several DVDs. I've seen other works by Kisugi-san, but I hadn't watched this 'Fondled by my Son' entry yet. I was disappointed. It starts with a random handjob/titjob and then a 3P with two suspicious guys who show up. Unlike the other entries, there's no incest with the son. It feels like a waste of Kisugi-san's assets. Such a shame!
