SERO-302 "Please, break up with that old man!" I barged into my father's mistress's room to demand a breakup, but I gave in to her erotic temptation and had sex.

What the hell, my old man has a mistress…! I found out where that despicable adulterer is, and I barged into her room to demand a breakup! Up until then, things were going well, but the allure of an adult woman made my dick react involuntarily… A triple combo of glimpses at her nape, cleavage, and crotch sent my original purpose flying out the window?! The woman, sensing my state, didn't ease up on her seduction… Before I knew it, I was lost in sex with her.
