A village inhabited by artisans blessed with natural talent, Bert, a resident of this village, is a craftsman capable of creating models modeled after his own buttocks. Struggling financially, Bert, hoping to strike it rich, tried to sell adult toys shaped like his own legendary buttocks, but couldn’t sell a single one. Just as he was drinking and feeling dejected, a man named Rick, a real hunk, happens to show up. Drunk, Bert ends up having a one-night stand with Rick, and he’s tormented by his inability to forget him...“Please sleep with me just one more time, Rick!!!!”(Source: MrBlue, translated)
