They cum, but you don't

You focus your thoughts on anything other than the amazing sex happening around. You block out the fucking, licking and rubbing going on. It's only doing this that you manage to hold out.

"Fuck- I'm cumming so hard," Justine cries out, her voice going up a pitch at the end.

"Me too," Melanie cries out.

You hear a pair of moans coming from next to you. You're guessing that they are coming from Lexi and Diddy.

As they come down, you pull out of Justine and rub her ass softly. Any more time in that pussy and you'd definitely cum. You know that they could get you back in action in no time, but you want to impress them with your self-control.

"Fuck- that was good," Justine says, looking back at you, "Amazing self-control."

"You didn't cum yet," Melanie asks, looking over at you with a smile on her face, "Thanks for holding it for me."

"It will be my pleasure," you reply, "You sure that you don't want to get fucked yet, Diddy?"

"I think I'm ready," she says, "But I really want to lick some pussy first. If you cum in Melanie, I can show you my oral skills as well."

"You guys must have really wanted this," Lexi says, rubbing Diddy's leg softly.

"Fuck yeah," Justine, Diddy and Melanie say in unison.

"Me too," you say, "So how do you want me, Mel?"

"Lay back down," she replies, "I want to fuck you nice and slow. I have some moves that I want to show off."

"That works for me. What will the rest of you be doing?"

"We'll switch ourselves up," Lexi says, "I want Justine's tight ass to sit on my face."

"That leaves your pussy for me," Diddy says, "Yummy."

Not wanting to waste any more time, you all begin to move into position. Now it just remains to be seen...
