I love experimenting with things. I had always wondered how it felt for a sick person who was horny tosatisfy himself with those funny medical masks on his face. I had visited my friend who is a doctor at his clinic and found a medical mask. I took it home with me. I jumped into bed and undressed completely. I wore the mask and started masturbating in it. It felt weird at first but I liked it as I went on. The thought of masturbating in a hospital bed where I could get caught was a great turn on.
