This is a drama about a tall woman with big breasts who gives a small man horse stimulants, makes him hard as a rock, and plays with him like a dildo or a vibrator. Ayaka(Ayaka Mochizuki) is a plain woman in normal life. At home, she keeps a man who wears a full-head mask and drinks horse stimulants to keep his dick hard all day. She rides on the man's face, smothering him and making him squirt, and even after he cums, she keeps stroking him until he squirts. It's 145 minutes of unlimited dick play!
