After getting Benjamin's consent, Miranda didn't lose any time. She stood up from the sofa and took all her clothes off with a hurried expression on her face. She then told him.
"Please lie down on the sofa."
He easily complied with her request. She immediately climbed on top of him, took her large tits into her hands, and stuck her boobs against each other. She spat on the valley formed by their intersection before rubbing them one against the other, lubricating them as much as she could. Once she was done, she took his dick in between her breasts and started to move them up and down, left and right, jerkingly trying to stimulate it. The feeling of her boobs on his cock was novel for Benjamin. It was a different feeling from a mouth or a pussy, just wet and warm skin surrounding his member, with his penis head sometimes coming out from the inside of her tits.
After yanking him like this for a while, she lowered her head and started to suck on his penis whenever it went out from her boobs. That increased the stimulation a lot, causing Benjamin to let a sigh of pleasure out. This pleased Miranda and she continued her titjob with redoubled efforts. A few minutes later, Benjamin groaned and suddenly came, his first sperm jet painting her face. She immediately took his dick into her mouth to catch the rest of his ejaculation. She greedily drank everything he let out and sucked on his glans to get any leftover. When she was done, she lifted her head and asked him, apprehensively.
"H-how was it?"
He smiled and answered.
"It was great, you did a good job."
She grinned in a little in relief, happy to receive his praise, and started to clean her face with her fingers, sending any remaining semen into her mouth. Benjamin saw her smiling with her face smeared with his cum and didn't need much more to get hard again. She saw him getting erect once more and noted, surprised.
"As expected, you can still go on. You are really incredible. What would you like to do next?"
Benjamin thought about it for a few seconds before answering.
"I am a man of my words. Since you did a great job, you can request something from me now. Feel free to say anything."
She opened her eyes wide in surprise, perhaps not expecting him to really hold on to his promise. She hesitatingly asked.
"Um, then, can we have sex?"
"Is that it? You don't need to worry about me, I am very open-minded."
Still, she delayed replying. Since she was stuck there, unmoving and not answering, he approached her and whispered in her ears.
"Let out your darkest desires, the ones you were too ashamed to ever tell anyone about. This might be your only chance in life to realize them, you know?"
Miranda shivered greatly at his words. She closed her eyes, panting for several seconds, before opening them again and glaring at him, crazy with desire.
"I-I have always been the one pleasuring others during sex. So... So, I have always dreamed about someone taking control and pounding me, again and again and again, and destroying my cunt with a big dick and fucking me so hard, so hard that I will lose consciousness and still continuing even after that until his dick forces me to wake up and fucking me more and more and more until I completely lose my mind!"
Miranda gasped after letting everything out. She experienced a feeling of liberation for the first time in her life. She had said it, whatever the boy would think of her after that.
Benjamin smiled and comforted her.
"You did great to let it all out. As promised, I will do exactly what you said. I will make sure that, when I am done with you, your brain will be mush and you won't even be able to remember your name."
His words and the lewd look on his face became the final straw for her. She shouted in raw horniness, climbed on top of him, and instantly impaled herself on his dick. She immediately orgasmed, her pussy squeezing strongly around his member. She then started to move her hips crazily on top of him, as if in a frenzy. Her pussy was completely drenched and very warm, making Benjamin groan in pleasure. However, he had to be the one in control since that was her desire. He started thrusting into her from below, disturbing her rhythm. For some time, their mating was a mess, with her dropping on him as fast as she could and him pounding into her with all his strength. Finally, Benjamin grabbed her hips and went on to regulate her movements, taking control of the situation. In her frenzy, she tried to continue banging herself on him but after another climax, she lost the initiative and became the one getting pounded. Benjamin didn't go easy on her and his cock continued to make her cum several times more.
"More, more! Your big cock, stronger, stronger! Oooohhhh! Again, again!"
He turned her on her back and went on pistoning from the top. He grabbed her nipples with both hands and pulled on them, making her come once again. Next, he sent one hand over her clitoris and started stimulating it, making her shiver. He then raised her legs until they were parallel to her body, her feet next to her head, and moved his upper body to completely envelop her from the top, taking her head into his hands and going into a long and sloppy tongue kiss with her. This position didn't allow Miranda any movement and he started insanely pile-driving into her. He went on and on like that, observing the changes in Miranda, keeping in mind his goal to satisfy her. She quickly started having orgasms after orgasms, with less and less time in between them, until she reached a point where her cunt went out of control, convulsing continuously. He felt a warm liquid on his pelvis and thought that she might have lost control of her bladder, peeing on him. Her face was a mess of fluids, with tears and drool smearing it, constantly distorted into a climaxing expression, even while they continued kissing without stopping.
Benjamin felt that he was on the right track and didn't release her in any way. He was also getting close to his release and gave a few last big strokes before ejaculating everything into her sloppy cunt. The feeling of his cumming into her sent her for an even greater spasm and she trembled uncontrollably for a full minute, her eyes crazy with pleasure. Finally, Benjamin felt her completely relaxing into him. He checked her face and saw that she had lost consciousness, with her eyes still open but completely unmoving.
