When I was 17, I decided to go into my room and masturbate for awhile. I took all my clothes off, put baby oil all over my penis, and sat on the bed with my favorite Playboy magazine. I was masturbating to the hot girls in the magazine for about ten minutes. All of a sudden, I hear my door open. The sudden noise sent me into an orgasm. I looked up to see my mom standing in the doorway when my orgasm started. I moaned and shot my cum all over the mazazine. It was a dead silence for a second, so you could hear my jizz ploping on the mazazine. After I am done, my mother looks at me on the bed facing her, naked, with my penis in my hand, covered in cum, sitting next to a playboy magazine, also covered in spooge. She says, "sorry, I did not mean to interrupt you" and walked out. She knocks for now on and has not mentioned this incident, which is good because it is so embarrassing.
