A middle-aged nurse who doesn't flinch when a male patient who is troubled by a big dick consults her, and who dodges sexual harassment. She seems impregnable, but when she is forced to insert it from behind, she is prepared to die... She feels so much that she loses her resistance to the stimulation of the big dick that penetrates her body! She shows such excitement that it seems as if everything she has been holding back explodes, and in the end she even begs for creampie!
