Iroha Meru makes her debut at an anal-licking specialty brothel, receiving meticulous customer service training from manager Iizumi Nozomi. She begins with a slow, wet kiss, her nipples being sucked and licked, then her exposed anus is brought close to the nose for a deep sniff. Next, she is driven to climax through intense rimming, with a tongue thrusting rapidly in and out in a piston-like motion. Further, she enjoys the cowgirl position with her anus widely spread open in a squatting posture, the tongue pressed directly against her. Her unique style of performance is one of her main attractions.
