Sleeping with the Enemy

While he pretends to be straight at work, Hiro Naruse likes searching online for guys to hook up with. One day, he agrees to meet a guy at a hotel... who turns out to be his worst enemy, Kagami! "Wanna give it a try?" Kagami suggests they do the deed anyway, but there's no way Hiro's going to let Kagami take the lead... and so begins their hardcore love life!
