Input: Text: so this actually happened over christmas break down in puerto rico. so i my girlfriend came down to pr with my family for a little vacation. my girlfriend had just had her wisdom teeth taken out about a month ago, and when you get your wisdom teeth out, they put you on an antibiotic just incase of infection. for some reason my parents let me and her sleep in the same room together while my brother slept on the couch. my parents would come check on us when they woke up to make sure we were sleeping in our own beds but before we would fall asleep we'd either cuddle or have some fun. 
this is where the good part comes in though. so we had been wait a month to do anything physical. the first night together in the same room was fucking awesome except for one little thing... we put some blankets on the floor in between the beds because the beds were super squeaky. she hopped on top first and started going at it. she finished first but i was super close as well. she looks as me and says "hey let's do it standing up, that usually gets you pretty quickly" (this is a very true statement.) so i said "ok let's go in the bathroom and close the door. so we head to the bathroom and she bends over on to the sink and i go right up behind her. after a few quick pumps i was about to burst! (let me remind you i had been waiting a whole month!) now here it comes and i pull out and she stands up and gets blasted in the back with the first shot, then i try to not make it get all over her so i stupidly aim up for some reason, the second shot is even bigger and it goes straight up and come right down at the top of her butt crack and starts sliding down... then the next two go right to her spine and start to drip down to the second shot. my last few just went on the floor, no biggy. but then we turn the lights on and she's got a very large amount of cum dripping down her butt crack. after we grab some toilet paper it is now dripping down the inside of her thigh and just looks really uncomfortable... i felt awful about the whole situation because i was in ecstasy while she was getting the worst of it...

edit: forgot to mention that she was on birth control but then the antibiotics made the pill defective for a month but when she was done with the antibiotics she started taking the pill again.
