Tell a story about being caught. I think the reason we have had so many threads here is because the ones we have have just had replies like "this one time my sister caught me". People want the details, and so new threads keep getting made. I will start. I used to have a couple girl roommates. Now I jerked off all the time, and was pretty careful about where and when. I usually waited until late, or until they were gone. However, this time I couldn't help myself. You guys are gonna swear this story is make believe but it's not. I was laying on the couch downstairs bored and watching tv when my roommate came down to talk to me about something. She was wearing a long tshirt, and I don't think she knew but her vagina was visible from my angle. I must've made a face when I saw it because she blushed and covered it up, then turned and walked away. She had the plumpest ass and it was hanging out from underneath her shirt. I was so turned on I went upstairs, shut the door, and turned on the computer. I am a vaseline jerker, so I loaded up and started stroking while watching porn. Right when I was about to cum there was a knock on the door. Usually I lock it but in my haste I forgot. She came busting in right as the tingling sensation came over me. I stopped stroking and just held it in embarrassment, but it was already too late, and holding it just made the orgasm stronger. She stood there in complete surprise as it arched through the air landing on my chest. I was mortified, and she was frozen there just watching until it finished. I sat there heaving unable to look at her. She merely said "sorry" and shuffled out of the room. It was uncomfortable for a bit, but eventually it went away. Talk about embarrassing yet hot.
