After a few beers, my girlfriend’s inhibitions have dropped to an all-time low. I ask her if she wants to have two cocks tonight and she says nothing, but her grin tells me she is ready. I grab my computer and post a listing on Craigslist. Within 20 minutes we hear a knock at the door. My girlfriend opens the door naked and the three of us don’t even make it to the bedroom before she has two cocks in her. My girlfriend bends over in the dining room and starts sucking my rock hard cock. Suddenly she feels a pair of hands on her hips and the tip of our guest’s cock gently gliding up and down on her slit. I hear a moan come from her cock-filled mouth and at that moment I knew he was inside her. As his thrusts became more forceful, so did the suction of her mouth around my cock. Since our guest walked in the door no words had been spoken. Suddenly his voice broke the silence as he said, “I’m going to cum!” After three more deep thrusts, there was a sudden still followed by a loud grunt and I knew he was dumping a load of cum deep inside of her, which sent me over the edge as well. My girlfriend remained in her bent over position and savored the feeling of having two cocks pulsating inside her at the same time. After what seemed to be five minutes, but in actuality was probably only a few seconds, our guest withdrew his slippery cock from her cunt, got dressed, and left without saying a word. After the front door closed, my girlfriend walked over and locked the door behind him. As she returned back to me in the dining room I could see his cum sliding down her leg. My cock became instantly hard again when the magnitude of the situation hit me. My girlfriend had just been seeded by a random man. Noticing my hard cock, my girlfriend grabbed my hand and led me down the hall. I said, “Where are we going?” She replied, “I didn’t take my birth control this morning. So you better put a load in my pussy and hope your sperm swim faster than his.”
