Rina Usui, a seasoned nurse with a penchant for the taboo, finds herself alone with a patient whose lustful gaze ignites her own desires. She approaches him, her hips swaying seductively in her crisp white uniform, and leans in close, her breath hot on his ear. "I know what you need," she purrs, her hand trailing down his chest, making his heart race. She unzips his pants, revealing his throbbing cock, and takes it into her skilled mouth, swirling her tongue around the head. The patient, unable to resist, grasps her hair, guiding her head as she sucks him eagerly, her eyes locked onto his.
