Summer means fireworks festivals! And fireworks festivals mean yukata! We spent a special time with Mizuna-chan during this seasonal event. I had met her before at an izakaya, so I invited her to this year's fireworks display. Amid the exciting, heart-pounding summer atmosphere, we grew closer—and as she let her guard down, I casually invited her back to my place. Currently single, Mizuna-chan works at a bridal company, leaving little opportunity for romance. Seeing her in a yukata, her sleek legs peeking out with every step, made it impossible to concentrate. That sight alone was enough to make anyone aroused. I gently caressed her thighs, building the tension, and when I casually glanced at her chest, I was shocked by how incredibly busty she was—her I-cup breasts were like national treasures! I passionately groped her huge tits, then used vibrators, dildos, and electric massagers to drive her wild. Once I entered her and started thrusting, her massive breasts jiggled wildly, almost like they were out of control. With cock and tits thrashing together, Mizuna-chan orgasmed repeatedly. Even after climaxing, she silently gave me a cleanup blowjob, smiling sweetly while stroking my cock. Judging by how much she enjoyed it, it must have been her first time in a while—she seemed incredibly satisfied!
