I and Tsumugi have been dating since college and are now living together on the premise of marriage. She's cute and kind, and I'd be really happy if I could marry her. …While she doesn't know about it … More than anything, with him! With my best friend Tsukasa! I can't believe it's going to be like that... Recently, I thought that "Cuckold" and "NTR" that I often see on the Internet have nothing to do with me. It's frustrating to wear it off, but... a story of a depressed erection cuckold that starts with a blowjob that gets you excited for some reason.
