Susanna

Susanna was a skinny appearing girl, with confused black hair. Her eyes were bright brown. Alex and her had fucked twice before entering the ring together at the Amazonia Boxing Club.
Usually, her routine was the reverse. Susanna always boxed a guy before anything, even before making friends. But Susanna had been suffering through a dry spell, so when Alex appeared in her life, she dispensed with formalities.
From the first bell, Alex went easy. Two nights with the woman currently smacking his face and torso had left him with a stronger sense of attachment than Susanna had developed. Susanna was aggressive because she had been intimate with Alex and floored him twice before he changed strategy.
Midway in round six, Alex grunted "There, you happy?!" as a sharp right hit Susanna's chin, putting her directly to sleep.
Emma the Ref got between Alex and Susanna, who slumped against the ropes, head lolling on the middle braiding, lower jaw slack. Emma didn't bother with the ten count.
"Mission accomplished! She's out of it!" Emma cautioned Alex, to whom the fight was not finished.
"Fucking hit me like I did something wrong!" muttered Alex, loudly, as he removed his gloves and went to his corner. 
"That's actually the point of the sport, Alex." Emma explained as she checked Susanna's vitals. They were good, but Emma could see Susanna would be gone for awhile.
"And women like her hit hard, it's their nature."
"Okay...fine.." Alex conceded.
"Grab her legs." Emma said. They carried the slumbering girl to the recovery room.

While she was out, Susanna had brief, crowded erotic dreams, involving Alex and a few other men. No matter how many times Emma asked, Susanna could not repeat her name or how many fingers Emma held in her face. The dazed boxer was occupied with figuring out why she never had group sex. By the time she was able to answer Emma's questions accurately, Susanna resolved to have a three way as soon as possible.

Alex treated his former opponent to dinner to make up for his punishing knockout. She listened to him intently as he apologized for fighting so impulsively.
"It was a sucker punch," he added. "I was wrong."
Susanna knew the punch that finished her was completely legal and that at least part of the motivation for Alex's repentance was the need to keep getting laid. None of that bothered Susanna; she believed he was sincerely sorry he'd hurt her. Alex was in love, along with being incredibly horny.
The next morning, as she snuggled against a  quietly sleeping Alex, Susanna decided to hold on to him. But, on reflection, she wouldn't include him in the three way.
