my female friend came in from out of town to visit me one weekend. she said she would get to my place late afternoon. when it was about noon i decided to masturbate. i do this by using the space in between my sofa cushions. i figured i had plenty of time so i stripped down and got to work. i was really enjoying myself and being loud. then i just heard laughing. my friend had found my key under the mat and let herself in. the first thing she saw was me making love to my couch. i jumped up but the abrupt motion from the couch took me to the point of no return and i started ejaculating as i tried to get to my room. i was humiliated that i had just cum in front of her and im not particularly large either so i didnt exactly impress her. but we were close enough to move past it. she still enjoys bringing it up though. thankfully never in front of others.
