I finally experienced the trending Spence breast treatment! Hatano Yui's climax scene, where she screams, 'This is... my first time!' was impressive and truly stunning. Especially the flow from the back towards the finish in the latter part, it was so intense that I couldn't even let out a moan, and the excitement lasted for an incredible duration. I was captivated by the transition from fainting to long spasms. This work can be seen as an evolution of the sensual massage from the 1980s, and Hatano's involvement was a success. If this could be developed into a series, it would surely be even more enjoyable. I also hope that next time, they will challenge other actresses, especially Mizuki Sakura or Kizaki Jessica. Experiencing this in the adult industry made me realize the endless pleasure with sensitive women, and that it is important to approach carefully and without haste. Additionally, I was amazed by Hatano's poses during filming breaks, which made me believe in the effectiveness. I hope this series continues to anticipate new approaches to continually stimulate the breasts. I myself am overwhelmed with the urge to recommend this to my acquaintances!
