First visit to a brothel, a chance encounter with Mom; incestuous relationship culminates in a bubble bath; Kaede Himeki (VAGU-074)

I stumbled upon a website advertising bubble baths for mature women. Although I always ignored these ads, one day on a whim, I called to make an appointment. When I arrived at the shop, I was shocked to find that the number one most popular hostess was actually my own mother!! After a long silence, my mother's superb bubble bath skills suddenly came crashing down on me!!
