With some help from the girls, yeah.

"I can do it," you say, "As long as you girls give me the right motivation."

"We can handle that," Diddy says, kissing your neck aggressively.

"Indeed," Melanie says, letting go of your dick for a minute, "Come down here and help me with this cock. Lexi- keep Justine occupied while we work."

"I know just the thing," your step-sister says with a sly smile.

Diddy comes around you and gets down on her knees. Mel feeds your cock to her and she takes it down her throat with ease. The other girls sucks on your balls happily, waiting for her turn again.

On the chair nearby, Justine is laying on her back. She has her legs up and she's holding them that way by means of her ankles. Lexi is sitting down in front of her and playing with her ass. She's plunging three fingers in at a time. She's going to fuck Justine's ass until you're ready to do so again.

"Are you going to cum in her pussy like you did to me," Melanie asks you in her soft tone.

"Or are you going to cum in her ass like you did to me," Diddy asks, giving your cock back to her friend.

"You should cum in her ass," Lexi calls back, "It's tight and warm in there. It's almost as tight as mine was."

"You girls are incredible," you say, "I'll be ready to go real soon."

"Good- you owe me one," Justine says, "The only one he hasn't had a chance to cum in the ass of is you Mel."

"I'm not ready for that just yet," she says, handing your dick back to Diddy, "All in good time."

"I'll wait," you say with a smile.

While you've been talking, Lexi has slowly upped the number of fingers in Justine's ass. She has all four of them in her now and she's teasing the thumb. She is pushing nearly all of her hand into her friend's super-tight hole!

The hot girls continue to work on your cock with true love and admiration. They are practically worshiping your cock. They enjoy working you over in preparation for one last fuck with her friend.

It's not long after this that your cock is as hard as ever and you're ready to go. The two kiss the head of your member in admiration as you move towards Justine again.

You tap Lexi on the shoulder and she gets the hint when your cock stands tall in front of her face. She gives it a similar kiss and moves out of the way. She keeps her hand in place for the time being.

"You ready for the real thing again," Lexi asks.

"Oh yeah. I've missed that cock," Justine says, staring at it hungrily.

You and Lexi share a look, coordinating your efforts. She gives you 'the signal' and pulls her hand out of Justine's ass. Within seconds, you plunge your hard cock into the hole, taking its place!

"Fuck- you're incredible," Justine says, "I want you to fill up my ass with your cum!"

You're certainly going to do that, but part of you wonders what the other girls will do in the meantime...
