Yura and I are a couple who started living together due to a casual situation. - One day, my best friend came over to my house, and things took a turn for the worse...When I was drunk and sleeping, I heard Yura's sweet voice and the sound of pistons. - Ah... I'm sure my best friend is having sex with Yura... - Normally I should have stopped, but I couldn't muster up the courage to do anything but pretend to be asleep...and I found myself with an erection while Yura was panting, which was incomparable to sex with me...
