Looking for titles with the theme of Dad encouraging his son to have sex with Mom

[Not2srius]

Older movie, MOM-03, has the son happen upon his parents having sex. Dad and Mom don't seem to care, and Dad even binds and blindfolds Mom and brings the son in for an inspection and blowjob. Any other movies with the theme of Dad encouraging his son to fuck his Mom?

I remember the DEEPS movie -
DVDES-926 A World Where Mothers' Sex Education for Their Sons' First Time is Mandatory;
Mothers Only Once Are Allowed Help Their Sons to Lose Their Virginity

Starring: Ayumi Shinoda, Nanami Hirose and Minako Kirishima




Long movie, 3H 20M, consists from some Japanese mothers sex education in three families.
At the very beginning, in Shinoda family (Ayumi Shinoda - as mom, and Yuzuru Yuki - as son)
the family father asks his son to get sex education from mother, just like he (father) had in his youth received
sex education from his mother himself. He is present at very first lesson of mother/son incestuous sex.

In the final part - that "only once" incestuous sex education develops to longer mother/son relationship...
