Many years later...

Lisa moaned and pushed back harder against the man who was thrusting into her from behind, making her heavy breasts and pregnant belly bounce and sway. She realised she didn’t know his name, not that it mattered. All she cared about was that he was a customer, and she was eager to do what he desired. As he unleashed a wave of cum into her already fertilised belly, she whimpered as her own orgasm hit.

As Lisa slumped on bed, the man dressed and left, sparing only a contemptuous glance at her, his seed still leaking from her wet hole. He didn’t say anything. There was no reason he should. She was just a cumgutter whore for him to relieve himself on.

As she lay, panting, she heard familiar voices outside, and the door burst open with an exuberance she recognised. Two beautiful young women burst in. They were dressed in petticoats, but their blouses were open to display their ripe young breasts, and Lisa knew that they wore no underwear, so that any man who lifted their skirts could freely access their tight asses and pussies. These were her eldest daughters, the twins Erin and Eloise, their bellies already beginning to show signs of the early stages of their pregnancies.

“Mum!” Erin whined. “Eloise let Reverend Stanleys fuck her butthole! She knows he’s my customer! He hadn’t even had a chance to bugger me yet!”

“Then you should have worked faster!” Eloise snapped back. “It’s not my fault that I’m sluttier than you. That’s why daddy likes me best!”

“He does not! When he sees me he always takes the time to finger me or spank me, or fuck me if he isn’t doing anything.”

“He does that to me too! And more often!”

“Girls, please,” Lisa said to the two pouting teenagers. “Your father likes you both. After all, he knocked you both up as soon as you were old enough, didn’t he?”

“Yes, and that’s another thing,” Eloise said. “He’s going to pop Betha’s cherry now, which isn’t fair, she’s younger than we were! Oh, I was meant to tell you, daddy wants you to come downstairs for it.”

Without bothering to dress, Lisa hurried downstairs to witness her third daughter’s deflowering. “Well,” she said as she walked, “maybe if you two didn’t keep creeping under her blankets at night and eating her out until she cums loud enough for the whole building to hear, maybe he would have left her a bit longer…”

As the trio entered the bar room of the brothel, whistles and hoots burst from the crowd of horny men gathered round the stage. Although she was older, Lisa’s nude, pregnant form was still beautiful, and drew as many of the ranchers’ filthy comments as her daughters. Once, the attention would have horrified and embarrassed her – now, it just turned her on.

She walked over to a table by the bar. Bethany was there, as naked as her mother. The wet stains on her thighs showed she’d already been up on stage, thrusting her fingers into her tight, virgin pussy to amuse the patrons until the main show. She was beautiful, even more so than her sisters, and her show had obviously done its job, as several of Lisa’s fellow whores were already on their knees with a mouthful of cock or naked and bent over the table getting used by the thuggish townspeople.

But Lisa’s eyes were drawn to the man who sat beside her, the man who’d **** the young cowgirl, impregnated her, made her a whore and ignited in her an eager cocklust. Bethany’s father.

As she approached he reached for her and thrust a thick finger roughly into her cunt. “Glad to see you’re here, bitch. I’d want you to watch as I make your daughter a slut like you. She’s fertile now, so I’m going to pour cum into her until I’m sure she’s knocked up with –my- seed, and then let any of the people here who’ll pay have a go with her. She should be nice and loose by the time I’m done. By the way,” he added with a cruel leer that sent a shiver through her. “I hear some slut’s come into town callin’ herself a ‘cowgirl’. While Betha’s stewing in cum, me and the boys are gonna go… visit her, welcome her to the neighbourhood. Maybe after we’re done, you can drink our cum out of her cunt and ass.”

Lisa nodded submissively. But Bethany, whose education had consisted mostly of watching the perverse things men did to her mother and sisters, spoke up. “Mummy, what’s a cowgirl?”

The brute looked at her, and Lisa replied. “Betha, a cowgirl is a woman who doesn’t know her place is to take hard cocks in her holes whenever a man wants, and to be pounded full of his seed until her belly’s fat with his babies.” Betha’s eyes widened at the concept as Lisa continues. “She wants to act like a man, to go and travel and have adventures.” Lisa sighed, a wistful look in her eyes. “I used to be one, until your father taught me I was a whore.”

With a laugh, the brute picked up his slender daughter, lifted her onto the stage and bent her over. She screamed in pleasure and pain as he thrust his massive cock into her, before drawing it out to show it to the audience, covered in her juices and virgin blood. A cheer went up from the crowd, and Lisa heard joyful shrieks from the twins as they were grabbed by lusty cowboys and put to work. A moment later, she was grabbed too, and cocks thrust into her pussy and ass. As she was ruthlessly pounded, she let all her doubts melt away into pure lust.

But up on the stage, her tender, fertile pussy being stretched by her father’s savagely pumping cock, Bethany thought about what her mother had told her…
