I recently had a MFM experience with a female coworker (24F) and her boyfriend (26M) which was a first for them, but not for me. We planned a second visit this past weekend together, as her parents were away again, and we could use their pool. On arrival, my coworker friend was in a tiny bikini top that was way too small for her DD breasts, but on the bottom she had shorts on. I complimented her, and then she broke the news to me that she just got her period. We had a few drinks and her bf bbq’d us some food, and him being the dominant one told her to clean up everything for us after we all finished eating. She made a few trips back and forth to grab plates, then teased him each trip by bending over in front of him so she could show off her tits. “What about our friend?” He said. Her next trip back to grab the final plates, she bent over in front of me, and I complimented her perfect tits again. They truly are perfect. We went inside to watch a movie, and before we started it I went to my car to grab a few beers I had brought. When I got back inside & down to the basement, my coworker was on her knees, tits out, sucking her BF’s cock. “Come” he said, inviting me over and when I got beside him she undid my shorts pulling out my cock which was already hard from the sight. She started sucking my cock, as her bf stood beside slowly stroking himself, then she switched back over to him as I watched stroking as well. She came back to me, back to him, then she brought us closer together and had us tip-to-tip and tried fitting us both in her mouth at the same time! Was a crazy feeling to feel my hard cock against another man’s, but she was fucking loving every second of it as her bf now started guiding her by her hair to swap between our dicks. He then told her to fuck my dick with her tits, and she got into position for a nice titty fuck as he jerked himself aggressively as he watched. He got himself too excited, and after a couple minutes pulled her back over to his dick as he unloaded into her mouth, which she spit / drooled back down onto her tits after. So fucking hot. I was ready at this point, and told her I was going to come, and she instructed me to cover her tits which I definitely did with a massive load. She was such a good slut, and I can’t get enough of her tits!
