MRXD-016 I'm sorry, father-in-law, you're a masochistic wife... ~My father-in-law's back bride training~ Sasaki Aki

It's been two years since I married into the Sasaki family. My life together with my kind husband and my strict father-in-law have calmed down quite a bit. The other day, I was gently comforting the unfulfilled woman's desires in the afternoon bedroom. I was seen by my father-in-law, who lives with me, as if it were just something I was so embarrassed to masturbate... ah... From that day onwards, my father-in-law's back bride training was made for me.
