Okay so me and my girlfriend decided one day that we were going to play the hold it game. My parents weren't home so we went up to my room. We sat on the edge of my bed and drank at least 3 bottles of water each. I looked over at her and she looked completely fine but i started to feel a slight pain in my bladder. Maybe it was because I had a start bucks coffee earlier but after awhile we both had another water. I felt a little pain in my groin but just tried to ignore it. Oh we made a bet. If she held it longer I had to put on a pair of her panties and bra and she could take a picture and show it to her and my friends. If i won I'd get to have sex with her on the beach (something I awalys wanted to do) so i knew i had to win. I asked her how she was doing and she said fine in a completey normal voice. I felt more pain in my groin and gripped the inside of my thighs. She looked at me and laughed. "You have to go already? This will be easy." I closed my eyes and tried to concentrate. 10 minutes later it was time to drink another bottle and i did. Wow I could really feel the pain now. I grab my crotch and started rocking back and forth. I looked over at her and saw her pressing her hands against her pussy. It kinda turned me on but i couldn't think about that now. 10 more minutes and i was doubling over. I hate having a small bladder. I downed another bottle slowly. My girlfriend said she had to go bad. I thought i'd win but she didn't let go. "your gonna lose' she said seeing my face all strained. My voice was higher than normal i felt like some one kicked me in the balls. HARD. I felt a little slip. Uh oh. I couldn't let her win. There was no way I could take another sip of water without letting lose. And there was no way I could move my hands without exploding. I knew even if i did win i wouldn't make it to the tolit in time. I couldn't even stand up. My girlfriend said time for the next bottle. (BTW we had to stand up to get the water from the table a few feet away.) I moaned. God it hurt. I stood up slowly and the second i did my knees shook and I dropped to the ground. Pee started gushing out of me. I moaned in pleasure it felt so good. I layed on the ground and kept pissing untill i was empty a few minutes later. I looked up at my girlfriend who hadn't moved. Her eyes were closed tight and i knew she was desprate. "carry me to the bathroom PLEASEEEE" she begged. I stood up still covered in piss and bent over near her. I slowly pushed her back on the bed. "PLEase i'm gonna piss myslef." she begged again. I knew how embarrassed she was and didn't want to go infront of me. I still wanted to have my fun so all i did was take my pinky and poke her lower stomach and she started pissing like a racehorse. After she started crying becuase she was embarrassed and sad she wet my bed but i told her it was a major turn on. it was hot
