Hardness returns! The high-density anal Airplane Cup recreates the sensation of a tightened sphincter muscle! The ultra-hard and tight K2MAN anal Airplane Cup has arrived! The Japanese A-ONE K2MAN series uses men's arms as a theme and has developed various anal Airplane Cup styles for those who love anal sex! Passing through the extremely tight anus, which is only 0.4 cm wide, you can experience the complex internal strip patterns and granular stimulation. The end of the intestinal wall even has a vacuum area, where you can feel the pleasure of rough granular stimulation rubbing against the glans. You can experience an even tighter and more forbidden super-pleasurable sensation!
