Starting from a childhood friend's consultation about her worries, this work surprised me with her large breasts suffering from low sensitivity! At first, I touched them with skepticism, and indeed, the response was dull. But her sudden shudder when her nipple was touched was shocking. The days of nipple development that followed, with sensitivity increasing daily, were breathtaking. Initially shy, she gradually moaned, her expression ecstatic. I couldn't help but get more excited, almost leading to something more intimate. This piece, depicting the moment their relationship transforms, captivates with realistic acting and a natural flow. The nipple orgasm scenes are a must-see, keeping me excited no matter how many times I watch. It's a masterpiece that goes beyond a mere青春 episode!
