Bizarre scenes kept filling his mind.
A particular recurring scene was one where Alan's big black cock was sliding in and out of Lisa's open mouth, her ruby red glossy lips liberally coated with his hot spunk.
As he indulged himself with these fantasies, he was incredibly sexually excited and at the same time disgusted at depth of his depravity.
In fact, if only he knew it, she was at that precise moment doing exactly what he was imagining.
She was like a bitch in heat, slurping noisily as she sucked and licked Alan's big black cock and whimpering as he fingered her well fucked pussy.
She had had a lovely meal with Alan before he took her back to his place for what proved to be a wonderful evening of pure unadulterated sex.
As soon as they were inside his flat Alan put on some sexy background music and asked Lisa to do a strip tease for him.
She was more than willing, and proceeded to tease him as she discarded her flimsy outer clothes.
Their eyes were locked as she weaved sexily back and forth while trying to
imagine what pleasures her black lover had in store for her.
He stopped her abruptly when she was down to her pink crotch less panties, garter belt, silk stockings and her sexy stiletto heels.
She looked gorgeous and he knew that she was now his to do with whatever he wanted.
He smiled knowingly as he realised that she was already addicted to his monster and would do anything he asked of her.
He quickly dispensed with his clothes and taking Lisa in to his arms he allowed his hands to grope and feel her gorgeous body, paying special attention to her tight little bottom and her ample breasts, and all the time complimenting her on how beautiful and sexy she was.
She made no attempt to stop him, as she rubbed herself against the huge bulge pressing into her soft belly.
For the next hour he fucked her twice.
The first time he made her kneel on the edge of the bed with her bottom raised, ready to take his massive cock.
Taking up her position she wiggled her bottom invitingly as she looked over her shoulder at his menacing monster.
Spitting on his fingers he rubbed the spittle around and into her tight little pussy.
Within a few moments he decided she was ready for it and positioning his huge throbbing member at the entrance to her slippery hole he slowly inserted it inch by inch into the hot depths of her hungry cunt.
Lisa emitted a low guttural sigh as she felt the big thick cock sliding in deeply and opening her up.
Her cunt muscles immediately started to massage the huge interloper as it sank in and impaled her.
Holding her by the hips, Alan went very slowly at first, building up a good rhythm and enjoying hearing the loud slapping sounds as his big balls smacked against the quivering cheeks of Robbie's sexy wife's bottom.
He momentarily wondered how a man could allow his wife to be such a slut for another man.
Putting it out of his mind he concentrated on getting every inch of his rigid cock as deep into Lisa's tight but well stretched cunt as possible.
Her cries and moans only encouraged him to increase the ferocity of his pounding and soon he was fucking her with wild abandon.
No longer the gentleman, he was now calling her his whore and demanding that she begged him to fuck her senseless.
She was in fact a whore at that moment and she pleaded with him to fuck her, to fuck her harder and harder and fill her with his boiling spunk.
After quite some time Alan could no longer keep up the ferocity of his assault.
Unable to check himself, he let out a long painful groan as he unleashed a torrent of hot spunk deep into the depths of Lisa's womb, filling her with his potent sperm.
Lisa screamed as she convulsed in the throes of an almighty orgasm, spraying the bedcover in the process.
They both lay there, exhausted and bathed in sweat, utterly knackered and unable to move.
It wasn't long though before she slid down the bed and gently sucked him back hard again.
Licking the swollen, spunk coated trunk and head of his prodigious black cock, she marvelled at the size of the monster which had been fucking her mercilessly just a few minutes earlier.
This was the exact moment that her loving husband, waiting patiently at home, was imagining her licking and kissing Alan's spunk streaked cock.
