I have always gotten hard and excited as I have watched my wife Kay having sex with either another man, woman or another couple.

The other day, I came home early, only to find a car parked in front of our house. In the morning, Kay mentioned that someone may stop by.

I went into the house but did not see Kay downstairs. I heard sounds from upstairs, so I went slowly up the steps to avoid disturbing what was happening there. When I got to the landing, I heard water sloshing in the bathtub.

When I looked around the door frame and into the bathroom, I saw my wife and a man taking a bubble bath in the tub. My wife was leaning against his chest as he was squeezing her breasts and nipples, which were covered in bubbles.

I watched as they stood up, washing and rinsing each other off. He had an impressive cock, which was hard and sticking straight out. After they had rinsed each other off, Kay knelt and began to suck and stroke his cock.

He then had her bend over, and he slid his cock into her pussy as he was massaging her hanging breasts. They looked so sexy hanging down with her hard nipples. He reached under her and appeared to be rubbing her clit, making her cum.

I slipped down the steps as I watched them get out of the bathtub and dry each other off. My wife left the bathroom first, and he was following her closely with his hard stiff cock swinging back and forth. They then went into the bedroom, leaving the door open.

I watched as they went into the bedroom; as she turned to go into the bedroom, she reached down, gently stroking his cock. 

She turned to kiss him, saying, “I want to feel this cock in my pussy again.”

She opened the bedroom door, and I could hear them getting into bed. So, I walked to the bedroom, looked around the corner, and watched. I love watching her without her knowing, as she is more relaxed than when I am in the room; she keeps looking at me to ensure it is okay. 

So, I looked in on them and found them passionately holding and kissing each other.  Kay was on her back, with her legs slightly open, and he was gently rubbing her clit and kissing her lips. He was also kissing and sucking on her nipples as they began to harden. 

Kay had her arms around him, but she also slid her hand down to rub his now hard cock.  His cock looked larger when compared to my cock.

Kay slowly kissed and licked her way down his chest. As she got to his pubic area, she turned to straddle his face with her pussy. They did each other orally till Kay had another orgasm.

He got onto his knees, and I could see that she had been rubbing the tip of his cock with his pre-cum, and it was all wet.  He pulled her to the edge of the bed, so her legs were off the side.  He then pulled her legs up as he took just the damp tip of his cock and began to rub her clit with it. 

I could hear her softly moaning as she was getting more excited. He then slowly slid his stiff cock into her wet pussy.  As the head went in, I could hear her take a deep breath in, as she was not used to getting that large of a cock inside her pussy.

As he began to slowly fuck her, I was excited watching him slide in and out of her but also seeing her tits as they were moving with each thrust.  He reached down and rubbed her tits, pinching her nipples a couple of times. 

When she was getting close to cumming, he paused and kissed her.  He then pulled out, and I could see his cock was wet from their juices.  He got beside her on the bed, she straddled his hard cock.  Before putting him inside her, she began just to rub up and down against his cock. 

She paused, then raised and guided his cock into her wet pussy.  I watched as she fucked him and kissed him passionately.  I could hear her tell him that she was coming and saw him raise and bury his cock deep into her pussy, as he began to squirt cum into her pulsating pussy.

I slipped downstairs to wait for him to leave.  He came down the steps, and she was naked, following him to the door.  They embraced one last time, and as he left, I could see cum dripping down the inside of her thighs.  She shut the door and turned to see me walking towards her. 

She said she wanted to clean up, and I told her I'd be happy to lick her clean.  I gave her a big hug and a long, passionate kiss.  I then asked if she enjoyed her afternoon, and she said yes.  We started up the steps with her in front of me, and me enjoying the view of her wet pussy and the cum dribbling down her legs.

I guided her to the bed, where I started to lick her legs and pussy, enjoying the taste of their cum.  I hope to catch and watch them again.
