PENIS ENVY
I was looking at Ken's cock. I know it's weird for a heterosexual man to look at another man's dick, but I couldn't help it. The thing was much bigger than mine and it dangled against his thigh, wet and shiny. It was wet and shiny from being inside my wife's cunt. It had come inside her and now limply hung there, her juices dripping from the shaft. A trace of his cum was oozing out of the little hole at the tip. I was tempted to grab the thing, to feel it get hard again, to have it fuck my wife again while I watched.
My dear wife Mina was lying on the couch, recovering from Ken's prick. She had that glow that she gets after an orgasm. Her body was flushed and she was still breathing heavily. She had been into it, almost screaming with passion as Ken rammed his prick into her willing pussy. He'd eaten her out first. She liked that. Having a man grovel in her crotch was one of her favorite things. I think it appealed to her feminist side, having a man down there, completely under her control, feeding him her cunt, stimulating his passion, making him want her, inspiring his primitive desire to get her pregnant.
I moved in and my cock slid into her slippery vagina with ease. Mina felt different when she was full of another man's cum. It was like my cock was immersed in a warm bowl of gooey pudding. His cum squeezed out around my cock, providing the lubricant. The lubricant for me to fuck my wife was from another man's balls. Mina had spread herself open for him, letting him fuck her, smiling at me as he did her. Now, his cum was what was between us. It was all over my dick and had oozed out onto my balls. The white mess had coated her cunt and was dripping into the crack of her ass. It was very decadent and very arousing for us to be fucking through her lover's cum. Another man had fucked my wife. He'd gotten her aroused and had provided the slippery goo that made our coupling so much more enjoyable. Fucking my wife when her cunt is full of another man's spunk is a favorite of both of us. Mina likes to tease me about getting sloppy seconds after another man has pleased her. She's kidding, because the orgasms she has with me when she's full of someone else's cum are unequaled.
"Come on, fuck me." She encouraged me, not that I need any encouragement.
"Put your cum in where he put his." She said.
I kept pumping, getting closer.
She continued, "I like it when you fuck me after another man has filled my cunt with his sperm."
I like it too.
She went on, "Maybe I'll stop taking my pills and let both of you try to make me pregnant."
The thought aroused me. She knew it did.
"Would you like to compete with another man to put a baby inside me?"
The thought was beyond the bounds of propriety. One didn't let another man impregnate his wife, but she was suggesting it, teasing me.
"I'd like to have both of you fuck me. He'd go first. Your sperms would have to fight their way into my uterus to get me pregnant. Would you like that?"
I wouldn't like that, but the thought was so nasty that it turned us both on.
She said, "Come on, baby. His little sperms are swimming inside my uterus. You need to shoot your guys in there and get me pregnant before some other man does it."
I pumped harder and she taunted me even more.
