My business has been occupying more and more of my time recently and my wife, Selena, felt I was neglecting her. She was right but somehow I was too tired by the time I got home to do anything about it. She's always had men flocking round her like bees after honey. One evening when I got home at midnight and dog-tired, she informed me that as I was always too tired to make love to her properly, she felt free to look elsewhere for satisfaction. She then went on to tell me that she had met a man and though she had not yet slept with him, she fully intended to do so.

Needless to say, I begged her to give me another chance but it made no difference and she telephoned him and made a date. She arranged to meet Keith at a luxury hotel where he'd booked a suite then informed me that I was to take her there and stay till she was sure it was safe.

She's always been strong-minded and once again she got her own way. She looked a picture of desirability when she came down the stairs. She was wearing black seamed stockings and her highest pair of heels. Her dress looked as if she had been sewn into it and really showed off her fabulous figure.

Once more I begged her not to do it but she ignored me. She looked excited and told me to bring the car round. He was older than us, very handsome and charming and I saw that my wife really fancied him. She openly flirted with him as we had a drink at the bar. After a very few words of greeting, when we'd first met him, they completely ignored me.

We went upstairs and in the lift she cuddled up against him. I was trembling with jealousy but meekly kept quiet and watched Selena rubbing herself against him like a bitch on heat.

Once inside the room, my wife, still openly ignoring my psence, was all over him and he undid the zip of her dress which slipped down around her ankles, soon to be followed by her sexy underwear. Naked, save for her hold up stockings and high heels, which made her look like a call-girl, she offered herself to him.

He sucked and nibbled on her firm breasts, leaving them covered with love bites and with the nipples looking so swollen that they seemed as if they were going to explode. Her head was thrown back and I could clearly hear her breath hissing through her clenched teeth as she clung to him while he feasted on her nipples.

I didn't know what to do. Part of me wanted to leap on him and beat him up while another part was too scared to do anything in case my wife really decided that she'd had enough of me and left me, so I sidled into a corner and sat down, nursing my aching hard-on and bruised ego, yet never taking my eyes off them.

I heard him order her, rather curtly, to undress him and meekly she did, which rather surprised me as she is such a strong-headed person and I'd never managed to get her to do anything she didn't want to do. My wife, who had always been so dominant with me, was acting like a lovesick slave doing what he wanted and seeming to enjoy doing it. She pulled down his boxer shorts and I nearly choked when I saw the size of his erection. It curved up from his groin like a banana, at least ten inches long but probably that was the shaft only. The knob was the size of a large plum. She was gazing at it with eyes like saucers while drooling as she whipped her tongue from one side of her mouth to the other.

Again, he gave her an order and she jumped to obey, walking to the bed where she lay down, spading her legs wide and holding her pussy lips open with her fingertips as he moved towards her.

I was shocked by her lewd behaviour. The way she was offering herself to him was almost obscene. I was tortured by jealousy to see her acting like a slut with a man she hardly knew.

Yet still I watched as he slipped on a condom before the dome of his mighty cock eased between her open cunt lips. Immediately that she felt the bulbous cockhead dilate her vaginal lips, she heaved up her pelvis and a few more inches of his thick cock was absorbed into her cunt.

I could clearly see her face contort with pain as he forced his huge cock into her. Her pussy was stretched so much that I thought it would begin to split at any moment.

A long, high-pitched shriek came from my wife's lips as the man drove the full length of his cock into her cunt in one mighty thrust. Her head jerked back and she whimpered between gasping for breath. He looked back at me over his shoulder as if to see where I was and how I was taking the sight of my wife's cunt being filled by so much cock, then he returned his attentions to my darling Selena, who seemed to have got over the initial shock of the huge penetration, because she was grabbing his hips to pull him down as her legs lifted up in the air. She began to pant and moan continuously as he began to fuck her.

Her legs were draped over his shoulders as he pounded his cock into her cunt as hard as he could. She gave every sign of reaching a huge climax and from then on seemed to climax every few minutes. I could not tear my eyes away and stared at his giant cock, plunging in and out of my wife's stretched pussy, gleaming with her juices. She was squirming under the pounding of the man, babbling obscenities and lewd, sexual encouragements.

I felt torn apart by a mixture of jealousy and excitement. I had taken my cock out and was wanking it as I watched another man shoving his huge cock in and out of my wife's hungry cunt. He continued to fuck her and she continued to come.

The most I'd ever known her to come during one love session was twice and there before my very eyes she had already quadrupled that number and he was still pounding his cock in and out of her and she was still climaxing.

Eventually, as she squirmed beneath him, her body covered with perspiration, her eyes wild with sexual madness, he speeded up his thrusts and gave every sign that he was ejaculating.

She went absolutely wild with ecstasy and he had to cover her mouth with his hand to muffle her screams as her pussy convulsed round his spurting dick. When finally he pulled his huge cock out of her cunt, I watched incredulously as Selena, who didn't like sucking my cock, pounced on his. She tore off the condom and tossed it aside before she took the head of his cock into her mouth and sucked on it like a starved puppy.

When his cock was squeaky clean, she lay next to him and they cuddled and whispered together before she turned round to me and told me to go home. Of course I protested but could not stand up to her when she lost her temper so I slunk out like a dog with his tail between his legs and went home where I waited for her to come back. It was the most agonised experience I've ever been subjected to. She didn't come home until the middle of the morning.

Later, after she'd taken a bath and I had served her breakfast in bed, she told me, in graphic detail, what they had done together when I'd left. The man was a sadist and had done things to her that I would never have believed she would let anyone do. Her body bore the bruises and marks to confirm her story.

She told me that she loved being submissive with him and intended to meet him as often as he wished and let him do whatever pleased him. She no longer cares that I'm too tired and is completely immersed in her role as his love-slave. I must admit, it excites me too.
