My name is Rob and I'm twenty nine. My wife Sally is just a couple of years younger than I and extremely good looking. She's quite tall 5' 8', slim with a tiny waist which makes her thrusting breasts look bigger than they are. She wears her blonde hair long and makes the most of her startlingly blue eyes and long dark eyelashes. Just looking at her mouth makes my balls vibrate and my cock tingle. There is something about the fullness of her pouting lips, the top one slightly fuller than the bottom one which is very sensual.

We had a reasonable sex life and I considered that we had a good marriage. I had to go away on a three weeks assignment so asked my father to come and stay at the house so that Sally wouldn't be alone. My Mum died five years ago.

I came home two days earlier than expected and decided to surprise her. I was eager to see Sally as we’d decided to start a family and she’d stopped taking the pill about six weeks before. This would be the first time we would make love with every chance of her falling pregnant. It was early morning and there didn't seem to be anybody up so I went upstairs to wake my wife. The bedroom door was partly open and I heard strange noises coming from inside. I was intrigued and, putting my bags down, I crept up to the door and peered inside through the crack. To say that I was shocked by what I saw is an understatement.

My father; fifty six years of age and wearing only a bath towel round his hips, was skinning down a pair of pyjama bottoms down my wife's long legs, while kissing her. She was naked save for the last garment he was busy taking off.

Sally has a wonderful bottom; two meaty balls of firm flesh separated by a deep crack, slightly overhanging over the lithe thighs; and its roundness is emphasised by the sliminess of her waist and this wonder of nature was facing me as she stepped out of her garment. She’d been sunbathing, while I was away, which made her white bottom even more pronounced and sexy.

They broke the kiss and I got my second shock when I saw that her sex mound was hairless. I wondered when she'd shaved it as we had made love only a few days before I'd left and her thick forest of pubic hair had covered her sex that evening. Her full breasts bounced cheekily as she moved and the nipples were already bright red denoting that she was very horny.

Despite the shock of seeing her naked with my father, in a most indecent situation, my cock began to throb as I tried to sort out my emotions.

Fully naked Sally sat on the edge of the bed. She said something to Arthur and giggled which caused her ripe breasts to jiggle and sway enticingly. Lifting up her hands she cupped her breasts and squeezed them so that the firm flesh oozed through her fingers and the pink nipples noticeably became fuller and redder. She looked very excited and I could see that she was shivering with arousal. One of her hands left the breast and smoothed down over her taut stomach, down her leg then up the inside of the thigh. She lifted up the other leg up onto the bed so that her bare pussy was fully exposed not only to my father’s eyes but also to mine.

I hardly dared blink as she started to stroke her pussy. She moaned softly as traces of moistness appeared on the lips as they slowly unfurled and revealed the deeper pink, inner flesh of her vagina. She was looking at my Dad; in a challenging way as one of her fingers disappeared inside her pussy and came out all shiny wet. She lifted it to her mouth and, with the tip of her tongue, licked the pussy juice off.

A mixture of emotions gripped me. Anger, disappointment and arousal. I wanted to rush into the room and confront them except that a strong desire to see what would happen next held me back.
My father looked at my wife, an amused smile on his face, as she returned the finger to her pussy and dipped it in all the way inside again. When it came out she stood up and walked to him and smeared the gooey stuff, along his lips and his tongue came out to collect it as she ran her hands over his broad, hairy chest.

His hands clamped her buttocks pulling her naked body hard against his. They started French kissing again and she rubbed her hairless mound against the bulge tenting the towel.

He kept pulling her buttocks apart and I could clearly see the rose bud of her anus and below it the hanging lips of her shaved pussy. I could detect a line of gleaming wetness slowly trickling down one of her inner thighs. She undid the towel, which dropped to the floor; and she must have grabbed his erect cock hard because he let out an agonised groan of passion. They swayed as they kissed. I could just see the upper half of his cock as her hand squeezed the base and he continued kneading her lovely bottom. She pulled back, turned around and walked in front of him heading for the bed. I heard his released prick slapping hard against his stomach.

Despite feeling jealous, angry and uneasy about spying on my father and my wife, while I should really be storming into the room and confronting them, I couldn't tear myself away. I felt shame wash through me when I undid my trousers and took put my throbbing cock so that I could hold it in my hand as I watched them.

My wife lay on her back and opened her legs wide open as she held her arms out to him in blatant invitation. Not wasting a moment my father slipped between her legs and, in one powerful thrust, buried his entire stiff penis into her sex. They must have been really dying for a fuck because that is what they did. They did not make love they fucked. Not bothering with anymore preliminaries he fucked her as hard and as fast as he could until they came off together. From the loud liquid sounds echoing in the room as he buried his prick all the way into her cunt it was clear that he was filling her sucking pussy with his sperm. Seconds later some of it gurgled and squelched out, round his shaft, to dribble down into the crack of her arse.

“Oh yeah...yeah...yeah, I can feel it! I can feel your sperm filling my naughty pussy. There's so much of it…so much...it's lovely!” my wife cried out as she orgasmed at the same time as him. Her eyes were screwed up, almost as if she was in pain, as she arched her back, one last time, before collapsing back on the bed. My dad’s chest was squashing her breasts as the driving motion of his hips slowed then stopped. They lay quietly, still linked together in post-orgasmic euphoria.

It was then that I realised that I'd also come. Ashamed of my cowardice I wiped my sperm from my fingers and got ready to sneak away.

However they were kissing again. Tenderly, at first, but soon more passionately until her body was writhing in renewed arousal. His mouth moved away from hers and kissed its way down to her thrusting breasts. They were flushed and the nipples were hard. He started licking first one then the other progressing to sucking them into his mouth. She rocked beneath him making small mewling sounds of approval. Her hands were cradling his cock and stroking it back into hardness.

A smile of pleasure lit her face as she felt his penis re-inflating. She pushed him over, on his back, and, still holding on to his erection, straddled him and impaled her sex on his upstanding cock. She started to ride him hard. I got the most wonderful view of her cunt slipping up and down his shaft as he continued to feed her tits into his mouth. She climaxed hard then slowed down before unplugging herself from his cock.

His swollen; purple glans made a plopping sound as it was uncorked, allowing a slurry of sperm and pussy juices to dribble out of her gaping cunt. It hung below her in long silvery strands caught the light like a diamond necklace.

It was then that the realisation that they were having unprotected sex, with all that it entailed, hit me.

As I wrestled with this knowledge she twisted round and sank her mouth over his penis taking almost all of it inside, and it was a fair size an inch or so longer than mine and thicker. She worked on it until her lips were buried in his pubic hair. I realised that she must be tasting the mixture of her vaginal juices and his sperm which coated his cock. It was something she’d always refused to do for me and strangely this made my cock start to throb as it slowly became hard again.

Her wonderful rounded bottom was pointed towards me. I could clearly see the firm cheeks framing the rose puckered anus with her open pussy below oozing white sex juices.

My father reached up and started to lick her out as she moved her lips up and down his cock. He ate her and she ate him while I, the husband, rubbed my re-erected cock like some hormonal teenager. He lashed her clit with his tongue, alternating this with sticking it -deep within her hole and bringing it out covered with juices which he smeared all over her clit. He licked her rose hole which opened and closed like a miniature mouth as he swiped at it with the flat of his tongue.

She lifted her mouth off his cock and, in a voice hoarse from arousal, she begged him to fuck her again because she really needed his sperm inside her sex. My wife who, with me, had always been a rather submissive lover was acting as if she knew what she wanted and went after it.

My Dad stood up and she went down on her knees, in front of him; and grabbed his erect cock in her hands. Her body was shiny with perspiration. She rubbed her large tits all over his throbbing cock, squashing them against the hard rod as she dribbled saliva over the crown before enveloping the wet length in her cleavage.

This was also something she’d never done with me.

He started ramming his cock in and out between her squashed-together breasts and his knob, each time it popped out from the top of her cleavage, looked ready to burst and I expected him to come off on her chest. However, before he could come, she pulled away and dropped onto her hands and knees, her shapely bottom up in the air waggling like a bitch on heat.

He dropped to his knees, behind her, and rubbed the head of his cock up and down the cleavage of her bottom before slipping it against the open lips of her pussy. A flick of his hips and his cock trundled all the way inside her until his pelvis smacked loudly against her bum cheeks. Sex juices oozed out as his cock moved in and out, slowly at first then faster.

My wife was moaning and grunting showing every sign that she was climaxing again. He took no notice and just kept on fucking her at his chosen speed. Gripping her hips he fucked his slime-covered cock into her sizzling pussy as hard as he could, again and again. It was fast and furious and she was pounded through one gurgling climax after another.

He said something about being ready to come and she moved away, twisted around and engulfed his twitching, slime-covered cock into her open mouth. Her red lips slid up and down the shaft until his cockhead must have been half way down her throat. She bobbed her head up and down as he held on to her head with his hands. An anguished groan came from him, as his head fell back and he closed his eyes. She removed her mouth from his cock and used her fist to stroke it. Her open mouth was only inches away, from the end of his cock, as his glans seemed to balloon. The first jet of white spunk blasted out and hit the tip of her nose hanging down in a long strand as the second jet blasted straight into her open mouth. He went on ejaculating strongly. Some of his sperm landed on her face while the rest went straight into her mouth.

It was sensational to look at and I nearly came again as my father bathed my wife’s face with his sperm!

As the flow of spunk eased she clamped her lips round the back of the glans and, from the way her cheeks hollowed, sucked out the last few drops. All the time she’d been sucking him she had been teasing her clit with her fingers. I swear that she was orgasming all the time.

Eventually she straightened up. She was swallowing the sperm and using her fingers to gather up the drops which were adorning her face and slipping them into her mouth so that she could lick it off. Then they kissed again and he said that it was time for him to go to the office.

Swiftly I grabbed my bags and headed downstairs. I made it out of the house only a few seconds before my Dad emerged and got into his car. I was in a quandary about what to do with what I’d learned. I saw a cab cruising and hailed it and asked to be taken to a hotel in the centre of town. I checked in then had breakfast.

My emotions were all over the place. I stayed there all day and that night. I phoned Sally that evening and told her I’d be home mid-morning the next day and she said she could hardly wait as she’d missed me so much.

I’d decided that I would not reveal that I knew that she was having sex with my father as I’d realised that it would not only lead to the break-up of our marriage but also to estrangement between my dad and myself.

When I got home Sally was all over me and we ended up in bed and it was sensational.

She gave birth to the most adorable girl. Working back I am sure it is my father’s child but I don’t care. I am a dotting father and he is the most wonderful grandfather any girl could wish for. Sally is once again pregnant and as she has continued having sex with Dad it could be his or mine.
