So this happened several years ago. In 2014, I was living in the city but was dating someone who lived an hour and 20 minutes away. She would come and stay with me every weekend and we'd just hang out and party with my flat mates and go to gigs etc as we were all musicians. She was friends with this girl (Lib) who used to live with me a few years prior. I had fantasized about Lib many times but never did anything because she was with a friend of mine. Anyway, one weekend my girl was coming to party and said she was bringing our mutual friend with her to party and catch up. When they turned up, my girl walked in first, gave me a hug and a peck on the cheek. I asked where Lib was. At that moment, Lib came in and ran up to me and jumped into my arms and wrapped herself around me and was saying how excited she was to catch up. Her and my girl were whispering to each other and kept looking over at me. I said "what are you two scheming?" They said "oh nothing" A while later, the drinks were flowing and Lib went to my bedroom to make a phone call. She was taking quite a while so my girl said I'll go see what's taking her so long. Another half hour goes by and I decide to see why they're both taking such a long time. I walk into my room to find them both half naked and making out. I say "what's going on here then?" They turn and smile at me and use a finger to motion me over to them. We start to make out with each other, hands roaming everywhere. With the girls fingering each other and both taking turns sucking my cock, we hear a knock at the door. My flat mate calls out and says that it's time for us to head to the gig. So we straighten ourselves out and get dressed and head out to go to the gig. The whole night, we're drinking and enjoying the live bands while continuously flirting with each other. We all eventually head home at around midnight. About 20 or so people come back to our flat to party the rest of the night away. As we're nearing 2am, me and the girls decide it's time for us to go to bed and pick up where we left off earlier. We spent the rest of the night satisfying each other till we were all absolutely spent. Honestly, I could be here for another hour typing all the details of the night but I'm sure you all get the idea. Needless to say, this is a memory that will never leave me. I still think about it frequently. Even all these years later. Turns out they had planned it on the drive to my place earlier that day.
