His sister was really good at this.
Holding Sarah’s head in both hands, he pushed his cock deeper into her throat. There was not a hint of struggle on her part - only her eyes were closed in concentration.
Well ... stepsister, technically. But they liked to think of themselves as brother and sister. It was hotter that way.
Finally, her lips reached the bottom of his cock, just as the tip of it bottomed out in her throat. They were a perfect fit like that. Her eyes slowly opened and looked up at him, half-lidded and glazed over. A gurgling sound, that he knew from experience was a satisfied groan, made her throat ripple around his cock and her eyes roll to the back of her head.
He felt like a king. Sitting on the living room couch, his legs spread shamelessly, his arms relaxing on the backrest – and his cock stuffing a woman’s face. He suddenly wished he had brought a glass of wine from the kitchen.
He leaned back and sighed, looking up at the ceiling, just enjoying the tight wetness around his cock. Sarah did her best to simultaneously please his ballsack with her tongue.
He looked back down. God, she was beautiful. Still looking up at him obediently with her blue eyes, her smooth-skinned face stretched around his cock obscenely. And that pose accentuated her curves so well – demurely kneeling, naked, her hands on her knees.
She knew not to move yet. The only muscles she was moving were her tongue and whatever muscles you need to continually push your face further into someone’s groin. That’s how he knew she was in a good mood - she wanted to attack his dick with everything she had right now. But she knew to wait until he started moving.
Their many sessions on this couch had given them that sort of understanding of each other. He remembered when she first managed to deepthroat him, right here. He came so hard he saw stars. She coughed it all up on the carpet, leading to a hectic clean-up before their parents came home. Later, thankfully, she learned to swallow.
He finally put his hands back onto her head, making her do a little excited bounce. He gripped her blonde hair, put back into a ponytail, and stopped for another moment to look into her eyes once again.
His cock must’ve been completely filling her throat for around two minutes now. He remembered when she first learned to breathe through her nose like that, too. Those were good times. They competed with themselves to set new records for how long his cock could stay in her throat, and how many times she could swallow his cum without his cock leaving her mouth. The record ended up at six hours and five times. They pretended to be sick to have an excuse to stay in bed all day for those record attempts.
So two minutes was nothing for her. She was comfortable – she practically grew up on her knees with his cock in her throat. Her well-trained jaw and throat muscles had not stopped giving him the highest-quality treatment she was capable of, tightening her orifice as much as possible and massaging his cock in exactly the way he liked it. If he had experienced this years ago, he would have come immediately just from that sensation. And she could keep up this setting for at least another half hour. She was a human deepthroat machine, the greatest sex toy on the planet.
Her kind, blue eyes still looking up at him, happily submitting, he finally started to pull his cock out of her throat, slowly and carefully. It felt sometimes that it put down roots if it was down there too long, like pulling the sword from the stone. Like her throat adapted to its invader, accepted it as a new inhabitant in its ecosystem. Hot breath, saliva, mucus, and stomach acid forming some unholy concoction to fuse his cock with her throat lining and keep it there forever. To create a new kind of Siamese twin, him having to carry her around his whole life, feeding her with his cum.
... anyway. He shook his head.
His strong hands, making her head look small, kept lifting her mouth gradually from his cock. Her eyelids fluttered and her lips stretched to their limit as the thick middle part left her mouth.
Post-throating moans were the best. He liked to think they expressed all the stored erotic energy of the throat session at once. And the longer the session, the better. So as the tip of his cock reached her lips, and was about to finally liberate her esophagus, he was eagerly anticipating it.
At the last second, her eyes rolled into the back of her head violently. Then his cockhead popped out of her lips with a wet smacking sound.
“UrprrAAAAAAaaaaahhhhhh...”. Her body shook and finally relaxed as the vulgar sound left the depths of her digestive tract – a burp leading into a high-pitched moan that slowly trailed off into a pleading high whimper. Her eyes returned to look at him. Her mouth was still open, with her tongue hanging out.
She let her upper body fall forward, below his dick, and her head fall back. Her breaths were deep and ragged. She rubbed her face up and down on the underside of his cock, looking up at him with aroused eyes. As agitated as she was, he noted with satisfaction that her hands were still shyly resting on her thighs, just as she was trained.
He solidified his grip on her head again to stop her from moving, and fully placed his hard cock on her face. His balls rested below her chin, making his dick bisect her face through the middle. It was thick enough to cover her nose completely, and only the very corners of her lips were visible. The length of it reached further, going between her eyes – which were both staring at it, giving her the idiot look that you get when you stare at your own nose – across her forehead, and to her hairline, with the tip reaching past her head in length and standing up into the air.
He always loved this visual, and groaned for the first time today. All that had been down her throat. She had long ago submitted to him completely.
With his big hands holding the sides of her head too, her face was almost completely covered – only her eyes, looking up at him again, peeked out between his fingers and his cock.
He couldn’t resist anymore.
He abruptly pulled her face back again. Her eyes widened and she reflexively opened her mouth as wide as possible. Then he pulled her face down and onto his cock. Again, but this time much faster, he bottomed out.
His sister was really good at this.
It was unbelievable how easily it went all the way in. It wasn’t just that she had trained herself to be able to suppress her gag reflex long ago – she was instinctively loose down there, even when getting surprised with with it. Deepthroating was second nature to her.
He pulled out again until only his tip was in her mouth, and then slammed back in all the way.
Then he finally started fucking her throat in earnest.
The sensation was amazing, the pressure of that tight canal. Her asshole had become slightly looser over the years, but her throat was still as tight as ever.
She held eye contact with him while her throat made a wet, vulgar noise with each thrust.
“GAHK! GAHK! GAHK! GAHK!”
He loved those noises. Sometimes he suspected she played it up for him. But he didn’t mind.
He plunged his thick cock into her mouth and throat over and over while simultaneously forcing her head down in the same rhythm, his big hands in easy control of her head.
“GAHK! GAHK! GAHK! GAHK! GAHK! GAHK! GAHK! GAHK! GAHK!”
This had been a learning curve too, taking his hard thrusts so easily. She explained it to him once. An intimate understanding of his thrust timings was necessary, and an intuitive sense of how exactly his cock molded her throat. It was very difficult – she had invested hundreds of hours of practice into this.
All that effort on her part was what allowed him to carelessly distend her esophagus for his pleasure like this. He read once that the throat was the second most vulnerable area of the human body. Well, not of Sarah’s body. He had learned over the years that he could handle this vulnerable hole as he pleased, and that it would only turn her on more. Her throat belonged to him.
His thrusts slowed down a bit, but became heavier, each one slamming into her face like a battering ram. But as challenging as the motion was for her, it was pure heaven for him – no matter how strong his thrusts, her throat lining received him like a pillow. Even though the base of his cock collided with her lips, his cockhead didn’t “collide” with anything as such – her innards just instantly molded themselves around each invasion like they were made for it.
“GRRK! GRRK! GRRK! GRRK!”
