This happened just last month:
My girlfriend is at university and shares a house with three other girls, we raley ever get a night in the house on our own so when we do we make the most of it. After we had kissed and cuddled and fondled etc. for about an hour we got down to the nitty gritty. My girlfriend had requested that I ahem ‘shower her with love’, if you get my meaning. So after an intense horizontal jogging session I pull out in order to take aim so to speak. At that very moment we heard one of her housemates (a very well to do girl) come into the house. The housmate must have thought she was alone in the house because she bounded up the stairs and let out a boombastic fart with each step! I started to laugh and with the effort of trying to repress my mirth and the fact that I was literally about to pop my nads let out a spurt of semen that hit me on the chin! Well this just set us off, my girlfriends lying on her back, legs akimbo absolutley red faced from laughing so hard and i’m sat on my haunches with man fat dribbling off my chin in near hysterics. We had to explain to her housemate that it wasn’t so much the ten farts she let rip that made us laugh (although it was the catalyst) but the involuntary ‘money shot’ that I had just inflicted on myself.
