One Punch

Destiny liked Joey, but she found most her clients were likeable people. Pulling a boxing glove over her right hand, she checked Joey one more time and felt she was safe. Joey was handsome, tall and physically well built, a recurring trait in the men Destiny worked with. Often they looked strong enough to give her a serious fight, even put her down and out. But they all craved a woman's knockout punch.
Aware of her sexual appeal to these men, Destiny knew how to be just seductive enough to stoke them. Destiny almost laughed when Joey admitted he liked black women in particular; two of his last three girlfriends had been African-American. This work taught Destiny to discern bigotry from fetish and Joey was solidly in the fetish column.
"All ready?" she asked, banging her gloves together. They were standing in Joey's bedroom, Destiny in tight shorts that clung to her amazonian thighs and Joey bare chested in sweat pants.
"You're going to knock me out?" Anticipation edged Joey's question.
"I'm knocking you out cold."
Joey's face softened, a sign of arousal was the cue. Destiny strolled to him slowly, alternately swaying her arms and then slamming her gloves forcefully.
"You're going to be so knocked out, you'll be gone till morning!" Destiny purred in Joey's face. Joey had forgotten that what was about to happen was going to hurt, especially when he came around. He was taking in every aspect of Destiny, wanting to know every part of the woman.
Destiny clasped his face with her gloves and pulled Joey into a tender, erotic kiss. Then pressing his head into her neck, she drew her lips along his jaw until she reached his ear.
"Good night." she exhaled, gently.
The right upper cut impacted his chin, hitting the 'off switch.' Joey's head jerked back and rapidly fell to his chest. Eyes closed, Joey wobbled a few seconds and slumped against Destiny.
She cradled him for a moment, kissing his head and then eased him onto the bed. Joey dropped heavily, his head just touching the pillow. Throwing down her gloves, Destiny lifted his feet onto the covers.

Joey was asleep for ten minutes. Destiny marveled at the bulge in the front of his very lose sweat pants. When he did come out of it, Joey was slow to wake  because he enjoyed the sensation of being completely laid out by a woman.
Later, when Joey was totally recovered, they fucked for an hour.
Both were so satisfied by the session, that when Joey asked her to stay, Destiny's first impulse was to deliver another KO punch to her lover. Instead, she dressed and kissed him, saying she was always ready for another 'round' whenever Joey was.
