By attacking her open anal hole, we pursue even greater pleasure! The one taking on the challenge is Marina Muranishi, who shows an extraordinary interest in anal pleasure. She tells us that she wants to feel even more pleasure from anal, so we attack her anal hole with fingers, a vibrator, and a dick, and even cum inside her anal hole repeatedly. Then, we open it up with an anal hook, and a "Gambiraki Anal" is born, so big that even a thick vibrator or a dick can't close it!
