Spending days with my childhood friend Yui brings a unique sense of familiarity and mutual trust. Having known each other for so long, she’ll usually agree to almost any outrageous request—as long as I’m serious about it. When I ask her to train me to stop being so sensitive in sensitive areas, she surprisingly agrees despite initial hesitation. At first, she snaps, "You just want to do perverted stuff, don’t you?" But after repeated pleading, she softly gives in: "Fine, just a little though, okay?" As I caress her most sensitive spot—her ears—Yui can’t hold back anymore and moans loudly, her voice overflowing with pleasure. "It feels so good… like, duh," she admits honestly, her excitement undeniable. In truth, Yui is incredibly easy to turn on. Time spent with her becomes a thrilling escape from the ordinary. 【Celebrating KMP’s 20th Anniversary!!】
