I became friends with 'Nanami-san', an older woman I met in a university lecture, and started dating her. After going to her place, we entered a semi-cohabiting state. Nanami-san, who deeply loves me despite my mediocrity, says she really likes me. Of course, I love her too, but I lack confidence in myself because I have premature ejaculation. However, Nanami-san accepts me as I am and teaches me about intimacy. With her gentle blowjob and titjob, both stopping just short! After enduring, the heightened sensitivity of my penis when we finally unite... it feels so good and I'm so happy!
