Me [M19] and my girlfriends [F19] First time experimenting

So we’ve been on the talk for awhile about letting her cuckold me as it’s been one of my biggest fantasies and I’ve been wanting her to do it. So recently she was with her best friend who is also a girl anyways so we were texting while I was home and she was out and about. We both were really horny and I asked her “what if you kissed your friend as apart of my fantasy” she was pretty shocked at first but after while of talking I received a video of them full blown making out. Jealous as hell but also horny I asked her if she was going to do anything else that’s when I started to receive a flood of videos and images of them making out and rubbing each other’s pussies. In the middle of her cucking me she asked me to go pick her up I was confused thinking something bad happened. I drove and picked her up that’s when I saw her and her best friend coming out both got into my car and my girlfriend talked to me for a bit and convinced me to watch a movie with them in her house. I went inside the house and went into the room where I laid on the bed next thing you know my girlfriend and her best friend are standing in front of me getting naked and they started making out and rubbing each others tits while I sat there getting hard I took my dick out her best friend was surprised about how hung I was they continued and laid next to me fingering eachother and making out. Next thing you know both of them are sucking my cock which was the first time my dick has been in another girls mouth but they continued sucking and next thing you know it turns into full blown sex with them cucking me in between best night ever.
