I arrived home early expecting the house to be empty; instead I found Anne's car and her fitness instructor Rob's car parked in the driveway. I had met Rob several times at the gym myself and he would occasionally come over for extra sessions with both of us, so I didn't think anything of it. I parked the car along the road and walked back home. I couldn't get my key in the front door so went around back and let myself in the back door. There was soft music playing which I assumed was from the lounge and another sound which I couldn't initially place.
Whatever it was stopped me from calling out, and I walked along the corridor towards the lounge and the sounds got louder, then I heard my wife, Ann cry out which left me in no doubt what was happening the other side of the door.
"Oh yes Rob just there, right there that feels so good, finger my cunt get it good and wet for your big cock"
I was taken aback and stopped in my tracks, my stomach was churning, my heart was beating hard and fast, and my mouth went dry. Then as the realisation that my wife was obviously being fucked by Rob, my senses started to return. Instead of wanting to rush in and stop what was going on, I found myself wanting to see what was happening. I retraced my steps and went into the Dining room which backed onto the lounge and found I could see into the lounge without giving away my presence. I looked into the lounge and saw my wife naked but for a red Basque and a pair of red stilettos bent over the back of our sofa, Rob who was totally naked, was giving her cunt a good fingering and was squeezing her tits with his other hand.
His fully erect cock was bouncing against his stomach and a pair of heavy balls swung between his legs. Without so much as a groan he lifted my wife with one arm spun her around, so her head was nearest the ground and her legs above his head. He held her up by wrapping his arms around her waist and she placed her thighs over his shoulders. He had easy access to her sopping wet pussy. She had unhindered access to his rigid cock. The scene was highly arousing as I watched my wife being tossed around by this hunk like she was a rag doll.
Ann had her hands on his thighs and her mouth wrapped around his cock, her head bobbing on its length. He was lapping at her pussy like a bear eats a pot of honey. Me, well I was desperately trying not to come in my pants. I loosened my belt and undid my zipper allowing my trousers to drop to the floor around my ankles. My underwear quickly followed and my erect cock, which was as hard as I had ever experienced, sprang free. My balls were taut and hard and ached with the knowledge of what would happen shortly.
I took a firm grip on my rigid tool, and returned to the sexually arousing scene I had come upon, my emotions were in turmoil. My wife was cheating on me, but instead of anger I was so aroused and desperately wanting to witness the outcome of whatever they were going to do together. They were still in the standing sixty nine positions and Rob was by now face fucking my wife, who by now had her hands firmly gripping his buttocks and appeared to be pulling him towards her eagerly awaiting mouth. The sounds of their lovemaking accompanied the soft music which had aided my unheard approach, to where I now stood unseen and unheard.
Rob then flipped her over, and almost threw her onto our sofa, her pussy glistening in the ambient light coming from the two lamps on the mantelpiece. Rod then grabbed her ankles and lifted her legs back onto his shoulders. Placing his cock against the entrance to her pussy he allowed his weight to push his cock into my wife's pussy. Ann was moaning throughout this, and it got louder as Rod went deeper;
"Oooooh Mmmmph!....Oh yes oh god yes fill my cunt you fucker"
Rob adjusted his feet once he was fully entered and then began to slide that cock in and out at a steady pace.
"Now you cock teasing bitch, prepare to be fucked senseless"
Rob gradually picked up the pace until I thought our sofa was going to break, so hard were his thrusts. My wife gripped the front edge as he hammered her pussy into submission. Her small body bouncing up and down as he did as he had promised, and fucked her senseless. Ann was grunting and groaning, like an animal at the fucking she was receiving. Shouting in between thrusts, dirty talk she had never been so far gone like this before;
"God, oh fuck, yes fuck, fuck, and ooohhhh yesssssss"
"Fuck me stud, fuck me, fuck my cunt, fuck it good you bastard" she yelled.
"Go on fuck the arse right of me, fuck my cunt like only you can you fuckin stud"
