He's to complete the plan

Josh thinks and thinks, Melanie and Mark staring at him, until eventually he decides that he can't afford to take the risk. Tonight the plan ends. And to do that he needs to do whatever it takes to get them off three times from his knees.

"I loved being on my knees; can I get you both off like that?" he proposes.

"I think we can accommodate that; don't you?" Mark asks Melanie.

"Absolutely," she says, her concern for Josh starting to be overtaken by lust.

They silently continue eating, each imagining what is about to happen. As soon as he finishes his meal, Josh stands up from the table, throws off his clothes again, and again kneels on the ground, wearing nothing but a thong and the seemingly-forgotten writing on his face.

Melanie looks over, but Mark conspicuously ignores him until finally he finishes his dinner. He then stands up, undresses - himself this time - and walks over to Josh, who watches nervously as the huge cock and balls approach him at eye level.

"Well, ballboy, I think you know what to do," Mark says.

Josh gulps. It was on. He sucks Mark's balls into his mouth again, tugging as before, pulling them away, letting them relax, pulling them away; Mark smiles, and his cock begins to harden. Josh takes it in hand to see if it is ready. Not quite yet.

Melanie comes over to see the spectacle, taking her gown and dropping to her knees beside Josh for a close-up view.

With the cock in his hand, Josh reflexively begins to stroke it as he would his own.

"Mmm," says Mark, "you know, I think I could use a mouth on my cock as well."

Melanie springs into action, moving in closer and pulling Josh's hand from Mark's cock, letting it flop down onto his forehead. She then leans in, licking her lips and sucking the head into her mouth. She then slides down his partially-erect shaft, sucking hard before starting to bob up and down.

"There we go," Mark says. "Work together, find a rhythm."

Josh speeds up a little, his mouth pulling away on Mark's balls as Melanie engulfs his shaft, then bringing them back in as she pulls back to suck his cockhead only.

"Ohh," he moans. "I made fun of ballboy for being such a natural cocksucker, but together...wow. You know what? I want you to suck me all the way off. A pair of cumlovers like you deserve it."

They continue until Josh begins to wonder: does sucking Mark's balls like this count? Or does he need to work the shaft himself? He doesn't really want to, but it would be rather unfortunate if none of this turned out to count.

He decides to be safe, and releases the balls, before wrapping his mouth around the base of Mark's shaft, sliding up and pushing Melanie off until the tip is in his mouth, just like he's seen in porn. He circles his tongue around Mark's cockhead, then starts to suck, sliding up and down the shaft. This time feels different, not being upside down: without the distraction from the huge ridge from his mushroom-shaped head, he feels a bumpy texture as the veins run across his tongue.

At the same time, Melanie has taken over the balls, and follows Josh's rhythm just as he had hers. He gets faster and faster, and Mark begins gently moaning, grabbing the back of Josh's head and gently thrusting into his mouth.

Josh mentally prepares himself for the fact that Mark is going to cum inside him a second time. He's going to feel that warmth, that disgustingly musky stale taste. And he needs to resist spitting it out.

Indeed only a minute later, he feels Mark tense up and start thrusting harder and faster into his mouth, like he's being facefucked again. This is the moment. Melanie sucks harder and pulls his balls away from his body as he's cumming, and thankfully the first load had partially drained him, as it's much smaller this time. Nevertheless, after the orgasm finishes, Josh pulls his mouth off of the cock and looks up, his open mouth displaying the new load.

Mark smiles.

"Well done, I bet you've been fantasizing about double blowjobs for years, haven't you?" he says. "Well now you've had your first one."

"You make a great pair, especially in your matching outfits," he continues. He looks at Melanie. "Is this your first time?"

"Yeah, I loved it," she says.

"Well then you should share in the reward," he says. He looks at Josh. "Give her a taste."

Josh holds her mouth open as she did with him, and lets the cum drip into her mouth, holding her head in place.

"Nice," says Mark. "Let's see it on those tits."

Melanie lifts her breasts up and together, then looks down and dribbles his cum onto her left breast.

Mark smiles.

"Now you can eat it," he says to Josh.

Two more to go, he thinks, before bending down, sticking out his tongue and licking Melanie's soft, round, cum-glazed breast, a little at a time and swallowing it as he goes. As he passes over her nipple he runs his tongue in a circle around it, and Melanie gives a little laugh; he continues lapping up the runny mixture of Mark's cum and both their saliva, until Melanie's breast is clean and shiny with saliva.

"Well, that was fun," says Mark. "Who's next?"
