My wife, Jake, and I went out for a few drinks, then back to our place around 1 AM. Since it was already late we didn't waste time getting things started. My wife and Jake began making out on the couch as I sat next to them and watched. Then she turned her attention to me, leaning back into my arms and kissing me. I reached around the front and squeezed her tits just the way she likes. Pretty soon his hands were down her pants and she was in heaven.
She went down on Jake first and sucked him masterfully while I fingered her. Eventually she turned her attention to me and gave me the deep throat treatment. She went back to him and he asked her to ride him. He sat on the couch and she straddled him. They were bouncing in rhythm and just having a great time.
I've got to interrupt here to give you some background info. My wife is not a big fan of anal. She'll give it to me sometimes, but it is a gift to me, it's not something she really enjoys all that much. In all the experiences we've had with others, there's never been any ass play because she doesn't like it so much, and those experiences are all about pleasure. But the first time we had an encounter with Jake, he asked my wife to let me fuck her ass. He really wanted to see her do that. But she replied, "I don't think so," and I backed her up by saying, "No, that's OK." But then she threw in, "Gotta save something for the next time." So she kinda put anal out there as bait to get him to come over again. Cool!
So back to our story... she's bouncing on him and they're all hot 'n' heavy. I reached down and slid my finger over her asshole. No objections, so I proceeded to push it in. My wife just moaned in that, "I'm so caught up in this wild crazy stuff I'm doing that you could do anything to me and I'm into it," moan. I fingered her asshole while Jake fucked her for a few minutes. I thought it might be time to take this a step further. I popped out my finger and greased up my cock with some lube and approached her from behind. I rubbed my dick head up and down her crack, but I couldn't get an angle to get it in her asshole. It was just too awkward an angle with him sitting up on the couch. I tried to push her more forward, but there was no where to go, so I backed off.
