On a bullet train heading to Kyoto, I meet a big-breasted office lady. We arrange to meet near a temple close to the station, and when we finally come face to face, her warm, friendly smile instantly draws me in. Even through her coat, the presence of her massive breasts is undeniable—so huge they seem to tower over the five-story pagoda behind her. After a brief chat, we head by train to her place. Her 1LDK apartment, where she lives alone, reveals glimpses of her daily life—packed with a treadmill and diet supplements, clear signs of her dedication to staying in shape. She effortlessly changes into loungewear and begins a relaxed, erotic performance. Dressed in modest beige clothing typical of an office lady, her voluptuous figure is accentuated by her full F-cup breasts and snug T-back panties that dig erotically into her soft, plump curves. Though she claims to be serious and professional at work, the sight of her underwear soaked through with arousal leaves no room for denial. I can't resist groping her flushed, oversized breasts before plunging deep inside her!!
