There turned out to be a lot more technique to giving a blowjob than Max had expected. Simply making an o with his lips and trying his best not to let the dick touch any part of the inside of his mouth did not make for much of a pleasurable feeling for his brother. He did as Kenneth instructed.
“Use your tongue.”
“Push it up against the roof of your mouth.”
“Watch the teeth.”
“Faster, bitch.”
“Take it all the way down. I know you want to, slut.”
Max was shocked at how dirty his brother's language was when he got aroused. And odly enough, it was somehow turning him on as well. Kenneth was really getting into ordering him around and dominating the situation. Max did his best, wishing Kenneth would just cum soon. This was taking forever and it was so wrong.
Kenneth grabbed him by the hair and started to shove violently into him. The cock sliding down into his throat, chocking Max.
“Yeah, you love this, don't you. This is all you're good for anymore, you know that? When we get back home, you're going to have to blow me every day and just hope that you did a good enough job for me to let you cum in return.” He was being too loud. Someone might hear.
Kenneth sat on top of Max. The cock all the way down his gullet. He let go of Max's hair and reached behind, pinching and twisting Max's nipples. His hips grinding away, while he tortured his big brother's nipples mercilessly.
“Take it,” he panted. “This is what you deserve, you little bitch. This is where you belong.” Max flailed pathetically beneath, completely at his brother's mercy. He could't breath. Finally, Kenneth pulled out enough for Max to gasp in air. Then it was back in. Wasn't he going to cum soon!?
Kenneth reached further back with one hand and caught Max's balls in his hands and squeezed. Max would have cried out, but Kenneth's cock down his throat gaged him silent. But it made Max's throat tighten. Kenneth moaned and shot his load while pulling his cock back out.
Part of the first shot went down Max's throat, while the other filled his mouth and smeared his lips. The second shot blasted him across the face, covering one eye. Kenneth moved backwards across Max as he came in waves of pleasure.
His third shot splattered thickly across Max's chest. The fourth across Max's stomach. The smaller after shocks of the fifth, sixths and seventh were rubbed against Max's still painfully erect cock. Kenneth still moaning with ecstasy and rocking back and forth in smaller and smaller humping motions against his brother's cock. Kenneth's cock rapidly deflating atop of Maxs' erection.
Max was drenched in his own sweat and his brother's cum. He tasted it and felt it running over him. Coughing and spitting the taste from his mouth, he looked up at his little brother though the one eye not blinded by cum. The blissful expression on Kenneth's face quickly flipped to near panic as he came down from his dominating high and saw what he'd done.
Max wanted to scream bloody murder at him, but as he still had to get used to, he could not talk. Kenneth jumped off the bed, quickly wiping off the few drops that had landed on him and pulling up his pants. Max was still uncovered, naked and soaking in cum. Cum that was sprayed on him, he realized, in a pattern up from his own cock. It looked like Max had cum all over himself.
Frightened by what had come over him and completely forgetting his deal to let Max cum next, Kenneth slung open the curtains and ran, leaving both the door to the hall and the privacy curtains wide open to let anyone see Max laying there in what looked to be his own cum.
Too late, Max cried out after his brother. He was still just as horny. More horny now, actually. And completely exposed. But Kenneth was gone.
