In the dimly lit clinic, Nurse Unicorn, her uniform tight and revealing, plays with her patient's forbidden desire. She asks, "¿Deseas donar tu semen para mi?" as she strokes his massive, erect cock. He nods, and she begins her skilled teasing, running her tongue along the shaft, tasting the pre-cum, before taking him deep into her mouth, her big tits pressing against his thighs. She moans, the vibrations sending shivers through him as she expertly works his futa cock, ready to swallow every drop of his cum.
