I had an experience during a heart rate examination where I was made to completely undress my upper body. The nurse explained that measurements couldn't be taken over clothing, so I had to remove my bra entirely. She touched around my nipples with a stethoscope, tracing the area, and then proceeded to firmly massage my breasts while pinning down both my arms. My nipples were twisted and groped roughly, and despite the discomfort, I began to feel a strange pleasure, becoming aroused and feeling myself grow wet. My panties were pulled down, and she touched me near my anus as well. The atmosphere was thick with tension and anxiety. The nurse gave me a confused look, her gaze leaving a deep impression on me. I couldn't say a word—just stayed there, motionless. Though this had nothing to do with the original purpose of measuring my heartbeat, the feelings of unease and embarrassment still remain vivid in my memory.
