For the past 2 years I’ve been lucky to be in a open relationship with my wife and best mate. What started as a one off thing has grown into one of the most amazing friendship the three of us could of hoped for. There has been so many great memories but one was the first time my mate slept over.... We had been out for the night and there was a lot of sexual tension between the three of us and we couldn’t wait to get home. I was driving and my wife asked if I would mind her sitting in the back of the car with my mate as we drove home. I said no worries thinking they just wanted to chat. As we headed of I could her them chatting away about the night and how they couldn’t wait to get home. About 5 minutes into the drive it went quite in the back and I thought they were just relaxing but then I heard a very soft moan come from my wife I looked in the mirror and seen my mate had moved closer to my wife and they were kissing…. I could feel my cock starting to stir but it wasn’t till I stopped at the light and looked back at them that my cock went rock hard seeing that they weren’t just kissing but my wife’s dress was pulled up and my mates fingers were deep inside her. My wife looked at me and I could instantly see she was in a zone and I knew both us guys were going to have a night to remember. As we left the lights her moans got louder and I could hear how excited she was.. It was hard driving as all I wanted to do was watch but home was only 10 minutes away and that’s where the real action would start. I looked back in the mirror but all I could see was my wife smiling back at me and I knew my mate had taken his seat belt off and had his face in my wife’s lap sucking and licking her swollen clit. The look of pleasure on my wife’s face drove me crazy and I was glad we were almost home. We arrived home and I couldn’t get out of the car quick enough to get the house unlocked. I turned to see that the wife and mate weren’t behind me so I went back to the car and open the back door to say come on let’s get inside to find her sitting on my mates cock riding him hard in the back seat and before I knew it my cock was out and she was sucking it in plain view of anyone who would walk past but none of us really cared at the time and after 5 minutes we decided to go inside and really get into it.
