Married With Benefits

A drunken confession from a bi-curious married man to his wife's gay best friend leads to a bisexual MMF threesome, and Tom experiences his secret sexual fantasy - being a bi cuckold and having his first time gay sex!

An excerpt from this story of a straight guy's first time bi sexual adventure:

"Have you guys ever had a threesome?" Kyle asked.
"No!" Allie said. "I never even thought about having another guy in the bedroom. I've wondered about another girl, maybe, but I don't think we've ever even talked about it."
"I don't think I'd be able to relax if I thought I had to please two women at the same time - I have a hard enough time keeping up with you!" I told her.
"Would you really be into that?" Allie asked Kyle with a more serious tone in her voice.
"Sure," he said. "You wouldn't be the first straight couple that I've hooked up with."
"Do tell!" Allie said.
"It was a couple of years ago," Kyle told her as he sipped his wine. "Remember that guy that I dated in college? David?"
"Sure, he was adorable!"
"He actually was just going through a phase when we were together. He got married to a woman a few years ago, and he called me out of the blue one day and said his wife offered to have a threesome for his birthday. She wanted to invite another girl, but he asked if it could be me, instead. She knew about his time with me, and she was cool with it, so we did it."
...
"What do you think?" she asked me.
"About a threesome with Kyle?" I was so shocked by the question that for a moment, I couldn't even think. I looked over at Kyle and saw that he was now sitting up a little straighter, moving his gaze back and forth between Allison and me.
"I already said I'd be into it," Kyle said as I continued to process the idea that my fantasy might actually turn into a reality.
"Are we seriously talking about doing this?" I asked Allison. "Like, for real?"
"Why not?" she answered. "If that's something you'd be into, I'd rather it was with me and Kyle than behind my back with some random dude you found on Craig's list!"
"I would never do that, babe," I told her, and I meant it. I would never cheat on her, and it never would have occurred to me to ask her to have a threesome with another guy. I had always assumed that my fantasy would never progress beyond the bounds of my own imagination.
"Is that a yes?" she asked...
