['don't touch my girlfriend!'... but i can't say it to his face. A timid guy, his girlfriend who moved to tokyo and became more open, and a slightly flashy senior at university weave a strange love triangle of being fucked and cuckolded. One day, while maintaining a platonic relationship, asuka suddenly suggested, 'let's do couple youtube!' confused, i replied, 'it's okay, i'll find someone else to be the boyfriend!' thus, a secret business couple unit was born. i participated as a behind-the-scenes cameraman and editor. suddenly, a slightly sexy video went viral, and before i knew it, the number of channel subscribers exploded. the two, feeling good about it, started coming up with more and more sexy ideas... in other words, i would film asuka and her senior flirting... it became so extreme that, as a ban measure, they moved the posting location to a paid fan site. what they were doing was basically av. they would forget to turn off the live stream and leak their lewd appearance on the net, or send me raw fucking videos saying, 'edit this nicely!' asuka is my girlfriend! ahh, running a vibrator and dildo all over cute asuka's body... what, asuka likes her back rubbed? her ears feel good too? did she moan this much when we had sex a long time ago? does she feel better than when she's with me?! every time i edit asuka's orgasm at home, i feel frustrated, but it's so erotic that i end up jerking off. is this what they call erectile dysfunction from depression... this is real ntr... one day, i became the target of a monitoring project. 'let's make the shy cameraman fuck by seducing him!' asuka, wearing erotic lingerie, straddled me and approached... juicy, stroking. where did she learn such a nice tit licking handjob? and something inside my heart broke... what will be the outcome of this love triangle?
