Diane's catfight

I need a finish for this story, I have it built up with a very, almost disproportionately top heavy aunt Diane as the protagonist--her stats seem a little bizarre but she's actually based on a girl I know the exact same height, though I guess the weight is a bit more, but same enormous bust--versus a woman from her office.
Not sure where to go from here except the typical catfight tropes of hair pulling, breast mauling, etc. I wanted the loser to get banged by the winner and her male valet but that seemed out of character. At the very least, it's an aunt and her nephew and whether she win or lose, whatever fate befalls the loser, or spoils to the winner, he is forced to take part.
For now here's the setup:

Ralph was a little bewildered what he was witnessing. His aunt, a normally well mannered and "proper" woman. She would scold Ralph when he was little whenever he would say words like "crap" as bad language. Now here she was, getting ready to have a knock-down-drag-out catfight with a woman from her office.

Ralph's aunt Diane worked at a real estate firm and she said there's constant tension to get the best listings and neighborhoods. She told him this as she drove to Alicia's apartment. He was gawking because Diane was dressed like she was headed to the office, a button up dress shirt with a short, dark grey wool skirt and sensible black heels. But her shirt was unbuttoned almost halfway, giving Ralph a view of his gorgeous aunt's large bust. Underneath she wore a leopard print teddy that laced up around her extremely large breasts.

Ralph's father had remarked that his sister in law was every "Black man's fantasy." He hadn't understood until he heard his other uncles commenting on Diane's that her ass could make a grown man cry. Ralph didn't know what her measurements were but knew she was a 38 G cup. She wasn't fat though, probably about 130 pounds. She's only 5'1" so with her round booty, she keeps herself in remarkable shape for being 40, by doing zumba. Because of her chest, she looks like an enormous fat woman; a weeble ready to wobble over as they shake like a waterbed whenever she moves--yet they look very firm.

When they arrived and got buzzed up to Alicia's loft apartment, both women immediately began berating each other verbally.
"Oh look, the cow showed up with her little veal cutlet boyfriend," Alicia sneered.
Ralph's eyes were immediately drawn to the brunette's 40 DD's that were practically bursting from her red halter bikini top.
"That's right," Diane piped up, thrusting her large chest against the brunette who was practically a giant compared to his aunt. Alicia had long dark hair, nearly down to her ass, and was very lean. It looked like she worked out as she a flat tummy and muscular legs. She was only 5'6" but practically towered over his short aunt.
"That's right bitch, I have a younger boyfriend. And not some sleaze bag you probably picked up from a drug rehab clinic," Diane yelled and pulled Ralph close by the arm, as if he were escorting her to some fancy event. Ralph finally tore his eyes away from Alicia's breasts as the women started calling each other bitch, whore, and every other dirty word he had heard on tv. He was eighteen but vastly inexperienced. He had been staying with his aunt since graduating high school, living with her while working as an intern over the summer. She wasn't shy about her body and had caught him oggling her body as she wore just a tiny terry cloth robe around the house. She said she always felt clothes were binding, especially her bras which she had to buy custom made.

Ralph saw the "junkie boyfriend" his aunt was alluding to, sitting on a futon, smoking a cigarette. He did look like every meth head he saw depicted on tv, probably 99 pounds and scabs on his arms along with numerous tattoos.
Diane said she was bringing Ralph along for backup, in case Alicia and her boyfriend tried to do a double team. He didn't know why his aunt was insisting he was HER boyfriend, she was twelve years older than him but having her hug him against her giant breasts couldn't help but give Ralph a hard-on.

"Oh yea bitch," Alicia was practically screaming in Diane's face, bent over some to poke Ralph's aunt in her huge chest. "How about loser leaves the company?"

"Fine with me cunt," Diane hissed and grabbed a handful of Alicia's hair and with that it was game on. Ralph jumped back near the door as both women began squealing as each had a handful of hair and were spinning in circles. Despite her size, Diane was pretty strong and whipped Alicia into the wall by the closet door--they were only a few feet away from Ralph now.

Diane had put her blonde hair in bun, her normal business attire, but it was quickly unraveled by Alicia tugging on
