Bound buddies (short story)

Danielle had been such a good slave, she had truly earned a reward but, as always, she ws kept in the dark about it until the last minute. Indeed, the blindfold she wore made the phrase particularly appropriate. But the fact that she was already kneeling on the bed in her lingerie with her wrists cuffed above her was definitely hopeful. The knottet rope between her legs was another clue.
Her lover had promised her a surprise, and when she heard a second set of footsteps enter the room behind his, her heart beat faster.
Could it be that she was about to get what she had hoped for so long? Sure enough, when the blindfold came off, thre stood her best friend Mandy, who she had lusted for endlessly, already cuffed and ballgagged, her camisole doing little to conceal her charms. Danielle couldn't imagine how her boyfriend had talked Mandy into it, but she wasn't about to complain.
In fact, when she found herself chained up, tits to tits, with this luscious firl, who had already lost what little clothing she wore, Danielle would willingly have kissed her lover's boots in gratitude, but that, as she knew, would come later. In the meantime, they would be whipped face to face so she could feel Mandy's sweating, writhing body against her own. It was positively delicious.
Then they were both naked, on their hands and knees with wrists chained to the headboard. Danielle could only imagine her lover's amusement at the sight of their upturned bottoms side by side. Always clever with the whip, he proved able to get them both with a single stroke, their startlet cries and murmuring moans harmonizing nicely.
Just to add a bit of cruel teasing, he chained Mandy with her arms behind her back, lips just out of reach over Danielle's pussy. It was enough to get them both pleading for the chance to show what good girls they could be. Laying them both flat on their backs, hands cuffed above them, he slipped in between to give them the opportunity.
It was truly an excellent surprise.
