Fuck Cathy almost to death
“Fuck Ethan… You fuck me so good… Thank you for fucking me…” Your hands rest lazily on Cathy’s big tits as she rides you like a diligent cowgirl. Her thighs must be aching but her pussy is clenching tight and drooling around your cock. “Fuck your sister little brother” she coos, deftly moving her hips. After taking Jenna you can tolerate a leisurely fuck and Cathy lulls you with her voice to a soothing rhythm while her juices runs down your balls. “How was it with Jenna?” she then asks without stopping her duty as a good sister.
“I fucked her and told her to forget about it afterward,” you grin and stare comfortably at the ceiling. It’s early evening and you wonder if Jenna is still lying in pain and twitching at school. Actually, you should be careful but… “I kind of don’t care.”
“Good thing, little brother. We are stupid women, just holes for your cock.” Cathy leans down and kisses you so deeply as if she were in love with you. “You shouldn’t care about us.”
“I just want to fuck her again and again,” you moan, occasionally thrusting into your sister from below, who skillfully receives your thrusts. “She wasn’t as skilled as you but fuck she was hot.”
“She’ll learn at some point,” Cathy helps you and lets her butt slam against your thighs. “You’re going to fuck her so many more times.”
“Or I’ll let her think forever that every time with me is her first time.”
“You’re so smart,” your sister coos. “She’s going to be in so much pain.” Then, suddenly, she stops fucking you. You open your eyes. “We should all be in pain.”
“Keep fucking you whore” you murmur.
“Yes, Ethan.” Cathy moves again, straining her inner muscles even more, milking you with skill.
“What exactly do you mean?”
“I can see it, little brother,” grins the girl. “You like this little slut. I can understand it somehow.” She stops again. You are close to climax and thrust into her but Cathy doesn’t react. “But just because you like her doesn’t mean you have to be nice to her. She loves you?” You nod. “Then you can be brutal to her too. She’ll learn to like it if you allow her.” Then she looks at you urgently. “And you should be brutal to me too.”
“You’ve already had your punishment,” is all you say. “Keep fucking.” But Cathy doesn’t move or get shocked. She wants to teach you something, wants to be a good big sister, what you wanted her to be.
“You still have two shots left. Use them. And learn to be a brutal monster with me and Jenna. Ethan, just because I learned my lesson, just because you broke me, just because I love you, doesn’t mean…”
Your hand shoots out and grabs her neck tightly. Cathy’s eyes widen and she sticks her tongue out of her mouth to breathe, but your grip is too tight. Then your other hand lands on her cheek and she flies off the bed from the force of the blow. Plumbly, she falls on her back onto the floor, then you’re already there, grabbing her tit and pulling her so hard that Cathy bites her arm to keep from screaming. Finally you have your sister on her knees in front of you.
“You stupid bitch,” you growl, giving her a resounding slap on her ass. “I decide what to do with you!” One more blow, then you ram yourself up to your balls in her tight ass. Cathy moans long and painfully as you feel her tighten around you. Then you fuck her fast and hard and spit on her back.
“Yes,” your sister growls, squeezing her eyes shut. “Hurt me! Hurt me, brother! Hurt me good!”
“You little bitch! You piece of shit! I will kill you!”
“Yes! Kill me with your dick brother! Yes!” Cathy gets wild and loud and you don’t know if your mother is home yet. So you grab your sister by the neck with both hands and squeeze.
Her asshole immediately tightens around you and you have to fuck against her with all your weight to be able to penetrate her. Cathy moans and gurgles like a dying animal but you don’t let up. She’s so tight and hot and your hands squeeze even tighter.
And then something inside you stops.
“Fuck!” you scream and your fingers turn white. You fuck your sister so hard that her hands hang limply in the air and her back almost breaks while your cock pounds into her asshole like it’s on a mission of destruction with a murderous speed. “Fuck!” It’s like a rush and you’ve never felt so alive while Cathy’s arms hang limply on her body.
And then it is time. You don’t know how long it took but your balls are tightening almost painfully. And then your hot sperm shoots through your cock deep into Cathy’s wide but tight hole. You moan one last time, pumping hard and brutally into her limp body, then you fall back, letting go of her and leaning against the bed.
Cathy’s body falls forward and her head hits the floor hard. Then your cum shoots loudly and disgustingly onto the floor between her feet in a loud farting noise as her body slowly slides to the floor until her pussy is covered in the stream of juice from her ass, mixed with a little blood.
And then she wakes up. She takes a deep breath, then coughs and gags as her body lies in the pool of cum. She twitches like a fish out of the water, coughing loudly and in pain.
“Ethan…” she wheezes and you move next to her, still weak from your orgasm. “Ethan…” Her voice is raspy and hoarse. You gently brush her hair out of her red face as she tries to look at you. A vein has burst in her eye and there is drool all over her mouth. “Exactly like that,” she wheezes, her voice barely audible. “Good… this way.”
“Fuck you,” you just grin and spit in her face again. Then you stand up. Your cock stinks and your body is sweaty. Time for a shower.
You hear the noises your stepmother makes from downstairs.
