Accepts you and says what you were all thinking.

"Well, it's about damn time that we did this," Lexi says, "You bitches are all crazy though- all four of you."

All of you smile big, devious smiles in response. She giggles a bit.

"Well, fuck me already!"

You press your cock further into cunt, its wetness allowing you easy entry. You're sure that Lexi is helping in that regard as well. You push your dick all of the way in her and 'hit bottom.'

"Fuck- so full right now," Lexi says, "You filled me to the brim!"
"That's the idea," you reply, moving it around inside her by rotating your hips.
"Damn," Justine says, "That's even better than having it in my mouth."
"What?!?"
"Don't worry about that now," you tell Lexi, "Focus on this."

She nods and lays her head back in the chair. You pull out a bit and then thrust back in her. She grunts loudly- her sounds making you happy. You do it again, garnering a similar reaction.

Happy, you grab her ass and begin to really fuck her good. She moans up a storm at that.

As you fuck her, you glance over at the others. What are they doing during all of this?

Justine is sitting on the edge of the hot tub, flanked on both sides by Diddy and Melanie. Each girl has one of her D-Cup breasts in their mouth and are rubbing up and down the rest of her body with their free hands. In exchange, Justine has her two hands buried in the girls' crotches. She's obviously rubbing them and fingering their pussies, given their moans.

Focusing back on Lexi, you work on your goal: to make her cum. It's going pretty well, given the constant flow of moans and grunts escaping her lips.

"Tell me how much you love this," you say excitedly.
"I love it," Lexi exclaims.
"More. Tell me more!"
"I love how you fuck me. I love how you pound my cunt!"
"Who's dick do you love," you ask, pressing her on even more.
"I love my step-brother's dick," Lexi cries out, "I love my step-brother's di-ick!!!"

In mid-sentence, her body succumbs to you and she orgasms. She's even more beautiful now, her body reacting as she gets the release that she has so long desired. She's masturbated before. She's cum before. This time, however, she's cumming from your dick- her deepest, darkest desire.

While she's cumming, you can her a trio of moans beside you. You glance over and see that Diddy, Justine and Melanie all cumming from their combined and mutual masturbation.

You glance back as Lexi regains her senses, her breathing heavy.

"That's the best orgasm I've ever had in my life," she says with a smile.
"Let's top that then."
"Oh? What do you have in mind, brother?"
