Our couple, me and Yura, began living together casually. One day, our best friend came over to hang out, setting off the worst possible scenario... Hearing Yura's sweet voice and the sound of thrusting as I was passed out drunk. Ah... my best friend must be having sex with Yura... Normally, I should stop it, but I lack the courage and can only pretend to be asleep... And there I was, getting aroused by Yura's moans, which were far more intense than anything she'd ever done with me...
