So I have a spur of the moment party this weekend, and a bunch of people from work come. After lots of alcohol, a female coworker came into the kitchen and kissed me. My SO saw this happen, and was all over me for the next hour for me to pursue it. So I did. I took her in the bedroom and asked her if it was cool if my SO came in too. She said fine with her. So he comes in, and me and the coworker continue what she started. We continued to have sex forever it seemed like, and it was hot as hell knowing my SO was watching. After a while, he inched his way onto the bed and found himself in the middle of our fun. His low tolerance for alcohol permitted me to do something he said he would never let me do. I stuck my finger up his ass at first, and finally graduated to my vibe. I full on fucked him while I'm being serviced by the hottest chick I know. This may not be freaky to you guys, but it was hot as fuck to me, and I just had to tell someone. Oh by the way, my SO said that was the most intense orgasm he's ever had, and he actually stayed hard afterward. I gotta do this some more!
