Yes, she does.

Melanie walks around the side of the chair and lightly pushes against your chest. You let her move you into position - laying back-first. She grabs your cock and rubs it up and down slowly. Her hand now wet, she brings it to her mouth and licks off the juices.

"Mmm...what a nice mix," she says, "Lexi and Justine's juices taste great together."
"Somehow, I think that you already knew that," you say with a smile.
"Yeah,...maybe. I hadn't tasted them mixed with your juices before though."
"I won't argue with you there."
"Good. Let's see the others get set-up real quick," she says, rubbing your cock again.

Lexi has already laid down on the chair next to you. Her left hand idly runs across your chest. Justine has gotten into position, standing high above your step-sister's head. Lexi's other hand runs up the young woman's strong calves, but is just too short to reach her pussy.

Diddy, in turn, is on her knees in front of Lexi's prone body. She's massaging her legs and running her hands close to the young lady's pussy, but not touching it. Are they teasing each other or you too?

The games are done it seems as Justine lowers her pussy onto Lexi's face. The blonde quickly moves her hands into a new position - grabbing and squeezing Justine's tight ass. Diddy has also leaned into Lexi's pussy and is starting to give it some loving.

"Our turn now," Melanie says, licking her lips.
"Hop on and show me what you've got," you reply, matching her tone.

She does just that, slowly impaling herself onto your hard dick. She grunts a bit as she takes you all at once. She clearly chose this position due to it giving her the maximum amount of penetration.

"They weren't lying earlier," the exotic girl says, "You really do fill a girl up."
"Your tight pussy isn't too shabby either," you say, "So should I..."
"Just lay there. I'll do all of the work, stud!"

Now that she's taken all of your dick, Melanie begins to rotate her hips. This causes your dick to rub against her pussy from a different position every few seconds. You can see her abs flex against her stomach as she does this.

"Belly-dancing skills...ugh...put to a good use," Melanie half-grunts/moans.
"Thank you, Teacher!"

Meanwhile, a chorus of moans come from next to you. Justine is moaning appreciatively at your step-sister's licking - something she acted shy about not twenty minutes ago. Lexi is moaning into Justine's pussy, which is probably aiding her pleasure. You even hear some moaning from Diddy, as it seems that she's content to rub herself while pleasing Lexi.

Melanie continues to grind herself against your cock. You can see her reach up and fondle her smaller, but still lovely breasts. Your hands move from the chair and up her legs. She looks down at you with a smile.

"I'm almost there," she says, "and I can tell that you are too. Put those hands to good use and we can cum together."

You pull both hands back to your face, but only to moisten your fingers. One of them roams back towards Melanie's honey pot and finds the outside of her pussy. You search for her clitoris, while also trying something else.

Your other hand starts out by squeezing her ass, which is nice and tight. You have an ulterior motive, however. You move it around the back and find her asshole. Using the wet finger, you begin to fuck her hole a bit too.

The combination of your dick inside of her, one hand rubbing her clitoris (easy to find when she's this aroused) and one finger in her ass is just too much for Melanie.

"Here it comes! Cum with me! Fill me up with your se-e-ed!"

Melanie is too much for you and you orgasm as well. Your load has been a long time coming and it is a big one. You empty yourself into her pussy for what feels like an eternity. It last so long that you cause a second orgasm in Melanie!

To your right, the girl pile of Justine, Lexi and Diddy are all cumming as well. All you can hear fully is the now-familiar cry of Justine, but it's obvious from the volume that the others orgasm as well.

Melanie, mostly-recovered, leans down and begins to kiss you all over your face and neck. She's pulled away, however, by Justine. She pulls the girl in for a long, lingering kiss.

While she's elevated, you can see Lexi be pulled out from under her by Diddy. The two begin to kiss passionately as well. You'd complain about being left out, but Melanie's pussy is still covering your cock like a glove.

You just smile and enjoy the sights for a while, knowing that the action will resume properly in a moment. You have to wonder now...
