I've been in many 3ways, but the hottest one was the night 2 of my fuck buddies showed up at the adult bookstore at the same time. They were both very well hung and loved it when I would worship their cocks. Robert was only interested in getting sucked off, but David loved to fuck me after I sucked on him for awhile. I know they didn't play together because they were always wanting somebody to worship their big cocks, they weren't interested in doing that themselves.
One night I went to the adult bookstore and ran into David. I was talking to him when Robert walked in. They both knew that I played around with the other one. David suggested to Robert that they take me into a booth so I could do what I did best. We picked out the biggest booth (which had plenty of room) and I started sucking them both off. I was taking turns between the 2 when David got behind me and started playing with my ass. He lubed it up and he started fucking me while Robert was fucking my mouth. It was incredible! We tried to get Robert to fuck my ass (he had done it 1 time) but he said he was only wanting to get sucked. So David continued to fuck me while I sucked Robert off. Robert came first, which caused me to cum which caused David to cum.
That was such a great night. I always wanted a repeat of it, but I could never get both of them to agree to do it at the same time. It was back to always one at a time.
