The sensei's study is dimly lit, the scent of aged paper and ink filling the air. His student, a raven-haired vixen, closes the door behind her, a mischievous glint in her eye. She approaches him, her silk kimono whispering against her skin. Without a word, she kneels before him, her fingers deftly untying his obi. He watches, his breath hitching as she reveals his throbbing cock, already hard for her. She looks up at him, her lips parted, ready to take him in, her eyes gleaming with anticipation.
