I'm a guy who went for a holiday with my female friend. We stayed in a hotel room and she was sitting at the desk doing her makeup using a small handheld mirror while I was watching tv. I was turned on from the thought of masturbating behind her. This fantasy made me very aroused so I pretended to watch tv but quietly pulled out my cock and started to masturbate with her sitting only a few feet away from me. I realised she could easily have seen me in her little mirror but that only made me more horny. My cock was so hard and throbbing from excitement. I was standing like that for a couple of minutes, while she kept doing her makeup. Then all of a sudden she turned her head around a bit to look at the tv and I nearly fainted from the shock because I thought she would see me, I froze in my movement because now I was in her field of vision but she was focused on the tv so she didn't see me. I didn't know what to do. I was standing there with my rock hard cock in my hand and then she just giggled and commented about something on the tv program and kept watching for a while. So I started to masturbate again, thinking "what the hell? if she sees me so what?". I answered her briefly and continued to stroke my cock. This was so fucking exciting! My pulse was rushing. Precum was coming out of my cock. She just kept watching the tv, giggling now and then..the thought of her being able to see me was too much. I almost fainted from the excitement, and right then I had a huge orgasm, which I tried my best to control. I held my breath and with a couple of last strokes I ejaculated several streaks of cum which was shooting in her direction. Some sperm even reached her and landed on her lower back. I can't believe she didn't notice that. Soon after she giggled again and returned to her attention to her make up procedure.
