MMV-80D - The Overflowing Sex Appeal of a 40s Madam 10

A person named Tomomi Yamaguchi definitely appears, but it's not the same Tomomi Yamaguchi as the one linked. I bought this thinking it was the Yamaguchi from 'Mother-Son Intercourse [Michi Ito]', so I was shocked. I like Crystal's mature woman series, but this one is mediocre overall. For mature woman omnibuses, it's safer to just buy the new releases to avoid disappointment.
