SPRD-1468 The sex friend at that time was... a friend's mother, Makino Kyoko

Honestly, I only then realized how intense the sexual desires of women in this age group are... and that aunt was into submission, doing whatever I said... Our relationship continued even after I went to college... When her husband wasn't home, we'd basically go at it non-stop at my friend's place. Lately, we'd casually go out to my house or love hotels to have sex like a regular couple... Honestly, I was getting tired of it... And then... an incident occurred...
