Just because Katherine understood the market forces at work which were complicating her attempts to find a boyfriend didn't mean she could resist their effect. The law of supply and demand was immutable. Education attainment had skyrocket about women, plummeted among men. Men valued looks and personality, ie how good the women were at pleasing their egos, most highly. Women ranked career success and education as most important.
Put together it meant when Katherine listed her must-haves for a potential boyfriend as having a PhD, mildly attractive and having a decent personality; she was in competition with every woman in the area. Any man her age that she would even consider dating had a boatload of yogini's chasing after him, Katherine had the disadvantage of being much older than those vapid 20-year-olds and she suffered from having a brain with all the opinions that went along with it. Luckily, she had big breasts because she definitely couldn't match their flexibility in bed.
After several years of fruitless search swiping away on dating apps, Katherine had yielded to the market forces. There was no more getting to know a man over a few dates before sex. Sex happened on the first date or she would never get a second. Men expected to get their cock inside her within a couple hours of meeting or they were back on their phones scheduling a booty call with a girl waiting in the wings. Anal was expected before she went home that night, with lube if she was lucky. But even with her compromises the men she was trying to get ended up going back to those brainless girls after sticking their cock inside her a few times. She was even beginning to swipe right on men old enough to be her professors, with their wrinkly skin and baldness.
Tonight, Katherine had gotten her hopes up. He was educated and witty, they had a great conversation over drinks in the bars for a few hours; talking about a bit of philosophy, recent events, the trials and tribulations in winning their PhD's. He had even been a gentleman and asked if she would like to come over to his place for a couple more drinks... that was a marked improvement over the more direct 'Let's go fuck' she had gotten last time.
The gentleman act didn't last long of course, she was on her knees with his cock in her mouth within five minutes of walking in the door. He didn't let her take her time either, roughly face fucking her mouth with his cock, making her choke and gasp for air as he looked down at her. He then pulled out of her mouth and pumped his cock a few times before it exploded all over her face.
'Catch it with those big tits. Don't get any on the carpet.' He said as he went into the kitchen to get a drink.
Katherine dutifully held her breasts together as his hot cum slowly slid off her face, beginning to pool in the valley between her tits. This would have been humiliating once but she had been toughened up by her past experiences. Well, it was still humiliating but he had a PhD, so she told herself it was worth it.
He came back into the living room with two shot glasses, one filled with some alcohol and the other empty. He looked down at Katherine and handed her the empty shot glass. He didn't say anything but she was a smart girl. She uses one arm to keep her breasts squished together and held the shot glass below the valley they made. She eased up the pressure a bit, allowing her breasts to spread apart slightly and let his cum begin to drain slowly into the glass.
He raised his glass. 'Here's to big titted whores that know their place in life.'
Katherine flushed and dutifully parroted 'To big titted whores.' Before downing her glass of cum, trying not to grimace at the taste.
It wasn't her idea of fun but he was almost cute. With a different haircut and some updates to his style she would probably find him good looking... So she smiled and exclaimed 'Oh how delicious' and begin to lick out the remnants of cum from the glass. She could see his cock begin to twitch a little, yep he loved it... this was going to be her escape from the single life. She finished cleaning out the glass, smacking her lips appreciatively.
She set down the glass and raised her hands to her big breasts. One by one she raised them to her mouth and licked as much cum of them as she could reach with her tongue. She spent a long time sucking on each nipple; she knew it drove men crazy to watch her do that and it was something most woman couldn't do. This was going to keep him from tossing her aside for some brainless slut that could put her heels behind her ears in bed.
When she finished she jiggled her breasts. 'Please come fuck me and fill me up with your cum.'
He smirked down at her. She knew that smirk having seen it on so many men before. He wasn't going to be respectful at all, he was going to treat her like the slut she was playacting as. But if she didn't act like a slut for men then they would just find a woman that would.
He reached down and slapped her breasts to one side. Then the other. Then again.
'Beg' he said as he kept slapping her breasts.
'Please fuck me. I've been creaming my panties thinking of your big cock inside me ever since the bar. I've tasted your delicious cum and seen your huge cock and I just can't wait any more. Please ram it into this over-educated, big titted whore and turn me into your brainless cock slave.' She moaned artfully, trying to make a face of a cock starved whore; mouth open, tongue slightly outstretched, eyes wide.
Her words made his cock stiffen in front of her. She was starting to get into character, she knew her intelligence wasn't going to win him over but it was going to be her big tits, tight holes and willingness to please him that made him invite her back.
He stopped slapping her breasts and put his hands in front of her face. She kept jiggling her tits for him as she licked off the cum he had gotten on his hands.
When he was satisfied, he yanked her by her hair, leading her over in front of a mirror leaned against the wall.
'You would just get my sheets dirty, whore but I know a slut like you loves being fucked on her knees anyways.'
'Please, may I please taste your cock again. I miss its taste already Sir.'
He smirked again and let her hair loose. She spun around and began to deep throat his cock to the best of her abilities. She worked as much spit into her mouth as she could and tried to transfer as much as possible onto the cock in her mouth. She knew where he was going to fuck her and she knew her spit was going to be the only lube. She used to bring lube with her until she learned that asking for a man to lube up his cock before ramming it into his ass wasn't what sluts do. Men only wanted sluts so she had to be one if she ever wanted to find her man.
'You'll get more of it later you cock hungry slut' he said yanking her off it by her hair painfully.
