Saturday night after the three of us spent all afternoon at the lake, half naked, talking about sex and dreams. We are back at our apartment, and we are about to have our first bisexual threesome. Me, just me, her, my live-in girlfriend of three years, and him, my old friend from college. I never imagined he was bisexual.

She says, "Let's start with this: I want to see you guys do a 69." We hesitate. "Don't worry,” she says, “I'll stop you before it gets out of hand."

So, we lay down on the bed with me on the bottom. I'm unsure, but he wraps his hot lips around my cock, and I start to tremble. So, just to be fair, I suck his cock too. His dick feels huge in my mouth. The shaft is so hard, but his cock head feels so soft. 

He sucks me harder. He takes my whole dick down his throat, and I gasp. He pulls off and sucks my balls, and I moan. He licks my asshole. I groan and grind my ass into his tongue. Then he sucks my cock again, harder, faster, deeper until I start to shake. I can't help but start fucking his mouth really hard. All of a sudden, I cum like a geyser. I gasp and thrust, as bolts of lightning fly from the top of my cock down into my throbbing asshole.

I gasp and shiver. In a cum-fueled frenzy, I wrap my arms around his hips and rub my face all over his balls. He starts to buck wildly, so I suck his cock into my mouth. Then he cums, and cums and cums until his sperm is forced out of my mouth and runs down my cheeks. 

"Oops," says my girlfriend, innocently. "I didn't think you boys would get out of hand that fast!"
