She is taking piano lessons. Her instructor, Miss Rei Kuroshima, is a kind, elegant, and beautiful woman. Lately, things haven't been going well with my girlfriend—she won't have sex with me. Amid this frustration, I find myself drawn to Miss Kuroshima, a more stunning woman than my girlfriend, and I ask her to give me private piano lessons instead. Miss Kuroshima stands behind me, pressing close as she gently touches my hands to guide them on the piano keys. Her demeanor seems easily swayed, reacting sensitively to the slightest stimulation. Unable to restrain myself, I reach back and grope her breasts. "This is... not right... ahhn!" she protests weakly, her face showing conflicted hesitation. Her reaction only intensifies my arousal further.
