After a minute more, he suddenly got an interesting idea. He waited for her next climax and when she was done shivering in pleasure, he stopped his movements and turned her back toward him. He was able to see her face again and it was quite the sight. She was very red, panting as best as she could through his underwear with tears running down her cheeks continuously. Her eyes were unfocused and she barely noticed him turning her around. He took her small head into his hands and asked her.
"How is it, Chloe? Did you like it?"
She didn't respond for a long time, looking at him vacantly. After a few seconds, she slightly nodded her head before realizing what she did and switching to shake it instead.
"As expected of my little sister, that was nothing to you, right?"
"M-moph courph."
"Right. I guess it's time for me to stop playing around and get serious, then."
Her eyes widened and he was able to read her expression as if reading a book. Her thoughts were probably something along the lines of wondering what else there could be when the previous rounds already made her feel so amazingly good. He saw her swallow her saliva, her expression a mix of fear and extreme lust.
"Goh on, noph aphraid oph anyphing!"
Even though she had a hard time talking, she was bent on never letting go of his underwear, making him laugh internally. It was now time to test if her bravado was justified or not. He reached his arms out to her and she instinctively came to cuddle him. However, instead of letting her hug him, he put his hands under her armpits and lifted her in the air. She let a small yell of surprise out but didn't try to escape from him as she had done before. He took her closer to him, stood up, and adjusted her position so that her pussy was just over his dick. This was the idea he had, remembering what he had done to Miranda, Karen's mother. The difference was that he thought it would work much better this time because Chloe was so much lighter. He hadn't been able to carry Miranda for too long but he would probably last much longer today.
Just like he had done the last time, he let gravity do most of the job, letting her small body fall on his cock, allowing her to get impaled hard. He stroke her cervix with force again and she let out a big moan of pleasure, immediately enclosing his neck with her arms for support. She could do almost nothing in this position, and he used the situation to his advantage. He held her at her hips and lifted her up and down, letting her get fucked by him in the air. The acrobatic position coupled with the strong stimulation pushed her to climax soon after, her legs stretching behind his back and her small toes arching up greatly.
In full control of her, he went on in this manner, increasing his speed progressively. Being manipulated like so, her thoughts took a weird turn. On the one hand, it was quite a humiliating position. She, a girl, was letting a boy use her just like a masturbation tool. She was just like one of those sex toys for men who would grind their dicks with up and down movements until ejaculation. On the other hand, there was a sort of thrill she never expected to experience in such a situation. The position itself was something she didn't anticipate and she obviously was in bliss to get her cunt attacked so hard. However, there was more to it and she thought the exhilaration she was feeling was because she was having sex with the person she liked the most in the world.
On top of that, even though she was more into normal sex where the woman had her way with the man, she had vast tastes. She wasn't against watching one or two - or three - videos where the man was acting domineering. That was why, even though her pride was a bit hurt, this situation wasn't far from one of her fantasies. Of course, she would rather die than admit to it.
All the while, her brother was continuing to use her as he pleased. His fucking of her twat was sending shivers into her back more and more often and her thoughts were getting severely disturbed. Eventually, he reached a maximum speed and her inexperienced small pussy went into total ecstasy, getting pounded several times per second. Her cervix, which she had unwillingly protected since she was born, was receiving all the missing years worth of poking, the pleasure piercing directly into her brain. He was still carrying her effortlessly and after a minute of this, her mind started to become blank under the pleasure. Adding to that the incredible taste and scent of his underwear as well as the strong odor of sex in the room, her view progressively went white under her sensations and climaxes. She gave up thinking about anything and only focused on the sublime pleasure. There were only two things left, her tight cunt and his massive dick, the second ravaging the first.
"Mffaahh! Mffaahh! Mffoouuhh! Mffoouuhh! Mffoooooouuuuuuhh!"
Finally, he sent one last enormous stroke in her twat and exploded inside her, a large amount of semen painting her small cavity, her tiny womb entrance gulping the fluids greedily. At that point, she came hard, squealing at full strength, her whole body tensing up under the greatest orgasm of her life. Her back arched once again and he had to hold strongly onto her so she wouldn't fall while still ejaculating inside her. Her pussy released wave after wave of juices, running down his crotch and legs, smearing the bed under them.
This was the best she ever felt and her brain overheated under the pleasure. After her orgasm, her vision switched from white to black and she fainted, her body losing all strength in his arms.
