"Damn you, stop that!" came the voice out of the heating duct.  I recognized the voice of my wife, but who was she talking to?  As far as I knew she and I were the only ones in the house.  A male voice that I did not recognize said:

 "You don't mean that baby, you know you love my hands on your body."

  Then my wife said, "But not here damn it! Ron is upstairs."

  The guy laughed, "He may be upstairs, but we both know he ain't going to be coming down."

Whoever he was he was right about that.  I was on my back in bed with my left leg in a complicated traction device, the result of a drunken driver running a red light.  From the clarity of the voices they had to be in the den which was right under the bedroom.  Carla said, "I don't care.  It's just not right for you to be here with him upstairs.”

  Again the guy laughed, "Not right?  Honey, I don't believe you.  You've been letting me fuck you for over a year now.  Is it right for you to be fucking me at all?"

  Carla said, "You know that I know it's not right, but I can't do it with Ron here in the house."

 "Sure you can baby," he said, "Here, let me show you what you really want."  There was a moments pause, "See?  He's ready for you.  Come on baby, give him a kiss." 

Carla called him a rotten bastard, but then I heard him say, "That's right baby, just like that.  Damn, but you have a great mouth.  Did you know that's what I like best about you?  That you suck my cock better than anyone else I've ever met?  I could let you do that forever."

I was astounded by what I was hearing.  My loving wife had been fucking another guy for over a year?  And I hadn't suspected a thing?  And just who was this guy?  Where had she met him?  How had their affair started?  So damn many questions with no answers.  I cursed the drunken asshole who had put me in this bed.  I needed to be able to get up and go downstairs and find out who this guy was.  His voice came through the vent again, "Easy baby, slow down a little.  I don't want to cum too quick."

Carla's voice:  "Fuck you!  You wanted this, and now you got it.  Are you gonna cum in my mouth or are you gonna fuck me?"

The guy: "God, but you are such a slut.  I'm going to fuck you.  How do you want it?"

Carla:  "I want it in my ass.  Fuck me in my ass."

The guy:  "What ever you want, my lovely little slut."

Carla:  "Take it easy.  Easy now baby.  Go slow."

The guy:  "Jesus, but you got a tight little ass."

Carla:  "God, baby, that feels good.  That feels so good."

Sounds of skin slapping against skin.  Low moans coming from Carla.

The guy:  "I love fucking your butt; it's so hot and tight."

Carla:  "God, baby - fuck me, fuck me, fuck me hard."

The guy:  "I'm trying, I'm trying."

Carla:  "Harder, harder, oh baby fuck me harder."

The guy:  "I'm close lover.  I'm close, I'm gonna cum."

Carla:  "Wait for me, wait for me, I'm almost there, I'm almost there, please wait for me."

Sounds of grunting and skin slapping against skin.

Carla:  "I'm cumming, I'm cumming, oh God, oh God."

The guy's voice over Carla's voice:  "Here it comes, I'm cumming, I'm cumming."

And then silence for several moments.

Carla:  "Now look at what you've done.  You got cum stains on Ron's new leather couch."

The guy:  "He'll never notice.  By the time he's up and around they will have faded."

Carla, laughing:  "You've gotten cum stains all over his wife too."

The guy:  "Not for the last time I hope.  Come here.  Suck me and get me hard again."

Carla:  "Not until you wash the shit off your dick."

The guy:  "Details, details, details, always the details."

Carla:  "Come on.  I'll wash it off for you.  We'll see if my hands can get you up."

Their voices faded away as they left the room.  God damn it!  Who was he?
