I've been thinking about this for a while: am I satisfying my wife during sex? Perhaps because of these thoughts, the frequency of our acts has drastically decreased. My wife is too good for me. Maybe there was also a complex of feeling inferior to her. Then one day, I caught my wife in an act of infidelity. My heart felt like it would burst with rage, but more than that, seeing my wife happily moving her hips on top of another man, the humiliation of losing to him swirled within me. However, contrary to my feelings, my erection was so intense that my pants were painfully tight; watching my wife being embraced and enjoying it by someone else made me want to masturbate. I actually came with just one stroke, overwhelmed by the intense pleasure piercing through my brain. The last time I had sex with my wife, memories of that day flashed back. Overwhelmed by sudden rage and humiliation, I ended up having rough sex with her, surprising her. However, the sensation of climaxing wasn't as strong as that time. Since then, I've been in contact with the other man, asking him to send me embarrassing pictures of my wife so I can masturbate. My wife is becoming more and more lewd, but I seem to have gotten used to it; I feel like I won't be satisfied with things as they are now. I think I'll ask the other man to do even more incredible things. My wife will probably accept even perverted acts. Seeing her in that state, I might pass out from over-excitation? Ah, just imagining it makes me feel both frustrated and aroused. I'll plan something wonderful after releasing some tension. Thanks to my wife and the other man, I can really enjoy masturbating…
