A year and more later.

You mop your brow and gaze on the peaceful faces of your sleeping babes. It's been a rough evening. First one girl would fuss, and while you were patting and walking her down to sleep, the other one would start crying. You think you've finally earned a few hours' grace.

You gently close the door to the girls' room and go to the kitchen to wash their bottles and clean up a bit. The infant monitor brings you the sounds of their quiet breathing. On the bright side, they are darling little things, and your wife says that soon you'll be able to afford some help. In a few months you might be able to go back to work. At least her career is thriving. She's out at another evening business meeting, or maybe it was a celebration of her latest deal.

You change clothes again, dropping your milk-stained jersey into the airtight clothes bin, and try and make yourself presentable. Not bad, you think, looking at yourself in the mirror.

The phone chimes gently. "John darling," Melissa says. "Almost home!"

"Mix you a drink, dear?" you ask.

"No, no. Mix yourself one. A tall Pellegrino for me," she says. The Italian mineral water is what she drinks when she's already had enough. "Girls asleep?"

"Yes, finally," you say.

"Oh, very good," Melissa says. "And I'm bringing a guest, my new personal assistant." She laughs. "Olivia, anything? Alright. White wine for her. Up in a jiff!"

You return the telephone to its cradle and pour the drinks, the palest possible scotch and soda for yourself. You light the gas fire in front of the sofa and adjust the lights.

Soon Melissa's keys rattle at the door. There's some faint giggling, a loud jingling thump, and a shriek of laughter. Your doorbell chimes quietly. You open it to find your wife Melissa with her hand round the hip of a beautiful black woman with her hair in tiny, severe braids, wearing a conservative business suit. Her suit is open at the top, exposing her breasts. She smiles gamely at you over her erect nipples. "Hullo Mr Cole!" she says.

You nod wearily. "John, please," you say. "You must be Olivia. Come right in!"

Melissa drags her new assistant into the house with more laughter from each of them. You scoop up Melissa's keys from the front stoop as your wife steals a quick kiss from Olivia. "Mmm, yes!" she says. She takes Olivia by the hand. "Come," she commands.

"I'm bursting, Mrs Cole," Olivia protests.

"All the better, this way then," Melissa says.

Olivia laughs and lets Melissa lead her off to the loo. The door closes and there is some laughter. The sound of Olivia's piss, a fast, high trickle. "My turn!" Now Melissa's, louder and more prolonged. A flush, and water running in the basin. More laughter.

Melissa and her new assistant emerge, smiling brightly. Olivia's breasts are tucked away now, but Melissa's hand is on her bum. You hand Melissa her water and Olivia her wine. For a while you talk business, Melissa holding forth expansively about her latest deals. Each time she says a good word about Olivia's assistance, she rubs her buttocks.

Melissa hands you her empty glass. "Darling, we have a couple things to finish up. Why don't you check on the girls and come by in twenty minutes?"

You take Olivia's glass as Melissa leads her toward the bedroom.

The twins are sleeping peacefully. You clean up in the kitchen and gather up Melissa's discarded coat and purse.

You take a deep breath and enter the bedroom.

Melissa's familiar rump is pointed back at you as she kneels naked on the bed, her head bent down between her guest's spread legs. Melissa's vulva is pink and swollen, damp with arousal, the lips slightly parted. You catch her scent from where you're standing, and your penis stiffens.

Olivia is gloriously naked, sprawled on the bed with her head on the pillow as Melissa noisily devours her pussy. Olivia's business suit lies neatly folded on a bedroom chair. Her nipples are even more swollen now, and you're sure Melissa has been chewing on them. Her eyes flicker open for an instant, meeting yours, and then close. Her head rolls left and right on the pillow, and her hips press up into Melissa's mouth. She clenches her hands into the bedclothes and climaxes, each pulse bringing forth a loud sigh and an undulation of her long, sleek body.

Melissa will be ready for you soon. You quickly undress. So much has changed since that party more than a year ago. Divorce, genetic testing, divorce, marriage, fatherhood...what a relief when Melissa was no longer pregnant.

You step up and place a hand on your wife's buttock. She shifts to bring herself to the right height, and you enter her. So good. So hot around your prick. So ready for you, as always.

It's not a bad life at all.
