Jun, a married woman who works at the same convenience store, is beautiful and kind, and has a reputation among customers. Jun seduces me with devilish whispers, "Shall I reverse-sex you?" It doesn't matter if she's on the phone with her girlfriend or in front of customers! Even in the store after closing time... In the end, I have creampie sex with Jun at her house, and I become more and more absorbed in our immoral relationship! Even after I ejaculate, she continues to reverse-sex me, and my dick feels like it's going to go numb! I have become a dick slave to my former wife...
