Sumire is my senior at work, still healing from a past relationship. Both of us recently single, we decided to unwind together over drinks—just the two of us tonight. At my place, we relaxed and enjoyed sukiyaki while sharing our thoughts and feelings. As the alcohol took hold, Sumire's cheeks flushed with warmth, making her look even more beautiful than usual. Mesmerized, my gaze drifted to her large breasts, so close and impossible to ignore. Noticing my stare, Sumire deliberately began teasing me with seductive movements, drawing me in. Before I knew it, she had laid back and straddled me, riding me with her big tits swaying as she rocked her hips, building her pleasure. Overcome with desire, I couldn't hold back and erupted inside her.
