The main character's mother, Tomoyo, is a seemingly calm and beautiful full-time housewife, but in fact she is a super bitch.

The buxom, whipped, bitchy mother is forced to wear young clothes that do not suit her age all over town, She feels shame and writhes and has a big climax under the eyes of the people who are discriminating against her youthfulness! She bites their penises!

And the act is getting more and more extreme...
