Sarah hears the sounds

Hino was starting to get a very large sense of important as she continued to pump her heavy hips forward, her massive cock disappearing down the throat of her childhood friend. She had never thought it would be this great to get her dick sucked down a hot, wet and slippery throat of someone she wanted to suck her cock! She had grown so used to having to rely either on hands, toys, or the somewhat reliable sluts at school that just wanted to take a thick futa cock down their throat. She had liked it at first but it was not the same as she felt right now, the way that her cock slid down his throat making her gasp as his soft walls gripped down hard onto her dick making her whimper as she pumped harder and harder. Her body demanding that she fuck his throat hard and rough she knew if she failed to do this that she'd never forgive her cock! Her balls slapped hard against the underside of his chin as she moaned in pleasure her dick felt like it was going to literally melt inside of his throat as she continued to hollow it out, allowing wet and sloppy sounds of flesh meeting flesh to fill the air as she fucked him without care of who could hear. After an unknown time she had lost track as she had finally gotten the throat of a femboy that mattered to her she felt her orgasms explode right down his throat. Her explosive and sudden climax rushed down his throat as she brutally filled up his stomach making his belly grow and expand his mocha skin pushed out in all directions as she flooded him with at least a full hard gallon of pudding thick futa cum groaning in pleasure before she finished dumping her load into his guts making him look pregnant, something she was going to attempt to do next, she had not thought of knocking him up this soon, however her cock was so hard that it was painfully throbbing as she pulled it out of his throat yanking it out with a harsh and wet plop! Her massive dark cock throbbed as she rubbed it on his face as it washed his face with saliva, old cum, precum and spittle. Her brown eyes met his as they stared at one another before she pulled it off and picked him up slamming his fat bubbly ass on the counter as she licked her lips pulling his legs apart seeing his tiny cock rock hard as already there was a deep stain in the front showing he had cum hands free as she smirked.
"Cumming like a good slut already? Chastity is not gonna be fun if this keeps up. Now I'm going to fuck that fat mocha ass of yours and breed you-"
"If you want to breed my brother, can you not do it so loud? I was trying to watch tv and now I can't keep the sounds out of my head." Hino and Vince paused turning to see Sarah standing at the door frowning, her dark eyes watching them as her skirt tented up showing a near equal size cock to Hino the futa younger half-sister of Vince clearly aroused as she coughed once. For almost a split second she was embarrassed as younger sister stared at her with neutral blue eyes before she paused correcting herself, Sarah was not a little kid anymore, even if she was still used to the teary-eyed tagalong from childhood she was eighteen now, she was an adult.
"Oh! Sarah this is not what it looks like! we are just... practicing massage tactic-"
"I saw you face fuck him. And cum in his throat."
"Oh... yeah... I'm sorry?"
"Don't be... he's sexy."
"Oh! Ok? I don't know what to do about that... what are you-"
"Can I join in? I mean... It's clear I want to fuck him so can I join?"
"Sarah?! We are related!"
"Only half siblings!"
"But you are my sister!"
"And!? I'm not a kid anymore, I'm an adult! You are my stupid sexy older brother, and I want to fuck you! So what!? C-can I join?" She asked as Hino froze as she replied slowly...
