The AV title 'Would You Like to Be an Underwear Experience Monitor?' features a hot scenario where college girls with big buttocks, approached on the street, are invited into the Magic Mirror vehicle for what they think is just a fitting, but escalates into T-back butt rubbing. After watching, I found the first girl had the best butt, while the third was the prettiest. The female staff also had such a nice butt that I wondered if she was an actress too. The last actress's shy performance was particularly erotic, making it hard for the male actor to resist. It's a great work full of buttock charm, with all actresses performing well. The close-ups of the T-back and the scene where it's pulled aside for insertion without being taken off are highlights—after such butt rubbing, anyone would lose control. However, some found the female staff's voice annoying, ruining the post-creampie interaction. Also, though T-back buttocks were supposed to be the main focus, taking them all off didn't match the title and content.
