As a single father, I had developed a close relationship with Yamamoto-san, a kind and meddlesome older mom friend. She had a voluptuous figure, her massive breasts especially striking. This time, she came all the way to my place to deliver something our daughter had forgotten while playing at her house. I had always wanted to see her bare breasts, but previously restrained myself because she was married. This time, however, my self-control finally gave way. At first hesitant and saying "No, this is wrong," she eventually gave in reluctantly. When she suddenly kissed me, I soon began moaning, groping her huge breasts passionately until I became fully erect. She gave me intense blowjob and titty fuck, and in return, I performed deep cunnilingus on her. Then, we began our affair with deep penetration—doggy style, rear entry, standing rear entry, more doggy, and finally creampie in missionary. Still unsatisfied, I ended up cumming on her face.
