Wait about chapter 10 page 12 to 13 did Masaya give his way to Hikaru? As if he actually insert it to him or did he not?
I think that Hikaru was prepared to let Masaya take him. But I think that either Masaya just pretended to insert himself into Hikaru or they performed double penetration in Yukio. Because notice how Yukio begins to moan louder at page 13. He was either moaning louder to distract the camera from seeing Masaya not enter Hikaru or moaned louder because Masaya entered him as well. I think it was dp.
Because a couple pages later, Masaya tells Hikaru that he didn't want make Hikaru humiliated nor did he want to have sex with him on camera. So that implies that Masaya wanted to, but didn't.
SEMEEEE I HATE YOU. YOU REALLY HURT IRIE'S FEELING! YOU DON'T DESERVE SOMEONE LIKE IRIE!
