You do it

You approach Jake. He's sitting on the ground, legs spread wide, leaning on his hands. You kneel down in between his legs and push your head forward. It's uncomfortable, so you lay down on your stomach instead, your head inches from his erect cock. You can see the veins and every bit of it, and to your embarrassment, it arouses you.

As your hand touches his hard member, he stiffens, then relaxes again. You groan a bit, then slowly open your mouth and lean forwards onto his dick. It tastes like regular skin, nothing bad, except for a few salty tastes of his previous orgasm. You begin pumping up and down, but after twenty or so seconds, come up, gasping for air.

After a couple deep breaths you continue again, for a bit longer this time. You feel some saliva drool out of your mouth accidentally, falling onto his ballsack. Jake giggles.

"Don't forget to swallow!"

Your face reddens a bit, but Jake says, "Don't worry, it's just getting it nice and moist. I want you to take your loincloth off now."

Resignedly you slip the loincloth off and hand it to Jake. He throws it behind him. "Continue, except vigorously. If I'm not pleased with this than I'll make you do it again!"

You get back to sucking, bobbing your head up and down. It wouldn't be so bad if it didn't make you drool and make you short of breath. Every once in a while you have to take a break for air. After two or three minutes, you start to taste precum. His whole dick is covered in saliva, rivulets dripping down off his balls onto the ground. The taste of the cum isn't too bad, and egged on by Jake, you continue.

Finally, you feel his body start to clench up. You pull your mouth off his dick, but he gasps out, "No! I want you to swallow it!"

"What?! No!" you answer indignantly.

"Swallow it or else you'll have to do the whole thing all over again!"

Reluctantly you lower your head and continue bobbing. After ten or so seconds, a hot thick liquid spurts into your mouth. He finishes six spurts, and is finally done. His erection doesn't go away though as you swallow the salty cum, grimacing.

Jake lies back, breathless. "Dude! That was awesome!"

"No it wasn't! Now can I have my loincloth back?"

"Nope!" answers Jake. "This is only the beginning. You've got a long night ahead of you. First of all, lick off all that dripping drool from my dick and balls. No hands allowed, sort of like bobbing for apples."

Using your forehead, you push his dick out of the way and lick his balls, sucking off the extra drool. Then you suck off his dick using your lips as a squeegee.
