By spooning on the backseat

"Lie down on your fucking side."

"Yes sir." Miranda does exactly that, and Matt does exactly the same. He then grabs your wife's dress and rips it open.

"Won't be needing that anymore."

Next, he grabbed his cock and slapped it against your wife's soaking wet slit. You watch as he guides the tip into your wife as she grits her teeth.

"Fuck, your wife is so wet." His cock proceeds to sink deeper inside of her. "It's gonna be flooded by the time I'm done."

Your heart skips a beat as for the second time you watch your best friend fuck your wife. You wonder if any of Matt's houseguests or neighbors will also become part of the audience, or if they can hear her cries, that echo throughout the car. The whole situation has you so aroused that you pull your pants down and start stroking your shaft.

"Oh my God baby... he's fucking me so hard..." Your wife cries.

"Yeah is he good?"

That's when Matt's hand begins rubbing her clit. "So good."

Next, he kisses your girlfriend's neck, and leaves a lovebite. A reminder that you let him fuck your wife and all you could do was watch. Your wife then gives you another reminder, by screaming "He's making me cum again baby."

As you watch her squirm and shudder, you know your wife isn't faking it just to tease you. Your best friend is really making your wife cum on your backseat, as if she's some back-alley whore he paid for the night. Once she comes down from her orgasmic high, Matt pulls his cock out, and spurts onto your wife's crotch, stomach, and the backseat of your car.

"Good little whore." He mutters, before kissing your wife. "Time to go inside."

His hands peel off Miranda's ruined dress before he opens the door. You put your throbbing cock away and follow the two outside. Despite being naked and covered in cum, your wife doesn't protest her walk of shame to the front door.

You find the other three waiting for you in the dining room. They all look to your wife before Kathy says "Damn. What did you do with her?"

"Tell them." Matt says.

"I fucked him on the backseat of my husband's car."

"And did he watch?"

"Yeah."

"Did you like it?"

"Yes Master."

Matt then turns to you. "I think your wife should thank you."
