The nurse, a muscular blonde MILF, enters the room, her eyes scanning the masked patient. She unzips her nurse costume, letting it fall to the floor, revealing a red, lacy bra and matching thong. She climbs onto the bed, her muscular body trembling with anticipation. She leans in, her breath hot on his face, "You're here for the vaccine, aren't you?" she whispers, before grinding her wet panties onto his eager mouth, her moans of pleasure filling the room.
