1st Bikubiku! Koharu Suzuki's listening toy game. Kiki Vibe is a game where you are blindfolded and try to find the correct answer using your vagina out of 5 types of toys that you taste. If the answer is incorrect, the fat man will punish you with a hard fucking insemination press... Will the fate that awaits Koharun be a golden seal or a hellish press and intense piston? ! The vibrator feels so good that I can't help but lose it.
