Had a nice, freaky memorial day. Had a BBQ with a few friends and my g/f over, brought the hot tub into play partway through the night. My best friend has had a 3-way with my g/f and I before, and he had been drinking and got a bit frisky with her, pulling the strings on her top and such a few times throughout the night. Eventually everyone else went home, leaving just the 3 of us. She started giving him a hard time about it, and then just kind of stopped... turned out it was because he was rubbing her pussy. I just let it continue and watched for a bit, then she grabbed both of our cocks and started jacking us off. After a few minutes of that I asked her what she wanted and she said to get fucked. I pulled her up on my lap and she started riding me reverse while he sucked her tits and played with her clit. Then she leaned back and said to me "you're being greedy." Last time we had fun she just sucked him off, so I was a little surprised, but went with it. She rode him for a bit, then switched back to me, then sucked my cock while he ate her pussy, back to him fucking her for a few, then I fucked her doggy style while she sucked him off, and that was pretty much the end of it. It had been over a year since we last involved him (or any 3rd person) and we both remembered how much we like it. Was a great night overall.
