Zoe.

"Hey there..." Zoe looks over her shoulder at you. Her back, tattooed and glistening is there for you to feast your eyes on, as well as her round ass cheeks.
"How did you get home?" You ask, getting over your startlement. Your cock is rising to attention. "Where's your car?"
"Umm....I had to leave it somewhere...for... reasons. I got an Uber home." She smiles. "Did you think it was Jenna in here? Is that why your soldier is coming to attention, Jimmy?"
You step into the shower, with a flat expression, until you reach out and seize a handful of her wet hair, and she gasps. "Don't..." you press her cheek against the shower wall, and put a hand to her crotch from behind, "call me...." you find her asshole, jamming your middle finger inside. She's coated with soapy water, so you slip in easily, though her sphincter is quite tight, and she gasps, "...Jimmy!!!" You twitch your fingertip around, stimulating the sensitive inner walls of her anus.
"Yes...sirrrr....." her words are squashed by the **** of your hand pressing her face into the hard tile wall.
"Where's your car, you little slut?" You jam your finger deeper inter her rear hole, and wrench her head back. Your cock is fully rigid now.
"I had to leave it at the Black Diamond... for collateral..."
"What are you talking about..."
She shudders as you **** her little asshole. "Dane's got a bad coke habit. He's been buying from 7ths, but he's behind." She swallows.
"So you, what? Sold Big Tim your car to cover it?" Big Tim Davidson ran the Black Diamond Nightclub and it's other associated businesses: a bar and a strip club in the same plaza. He had connections to the 7th Street Boys.
"No... Dane... asked me to... persuade Big Tim for an extension. So I go and... get an extension for him... every couple of weeks..." she looks at you with fear.
"Zoe..." you pull your finger out and spin her around. "How do you get the extension?"
"You know how..." she looks down. "But I told him today, I was done. That's why Dane hit me, actually. I told him I... I wouldn't fuck for him anymore."
You push Zoe to her knees. She looks up at you with devotion, and starts to stroke your cock. "So... if you aren't supporting Dane's habit anymore, why..."
"Because Big Tim's an asshole. He doesn't care that I left Dane. He likes having me around...his personal fuckdoll. He throws me to his boys sometimes. Today, when I told him I wasn't going to do it anymore, he made me suck his dick, and he and his brother nutted on my face, and then he said he was keeping my car as collateral until I worked things out with Dane, and got his debt settled."
"Well, that's unacceptable." You grab her by the hair. "Only I get to do that. Open up."
"Yes, sir... you're the only one I want using me, daddy..." She starts sucking your cock, never breaking eye contact.
"Mmm.... how much does Dane owe?"
Zoe starts to pull off, but you hold her down on your cock. "Vifdin gowzand....." she slobbers and gargles as she tries to answer you while you poke her throat.
"What?"
"Vuvteen dousin...."
"Fifteen Thousand dollars?" You say as you push her all the way down. Her eyes pop, and she nods.
You think about Zoe...your little half-sister... pleasuring Big Tim and probably several of his boys, for the sake of that piece of shit. You can actually picture it.

"Well....we'll just have to see what we can do about that..."
"Jmmmm....!" Zoe shakes her head, eyes wide. You pull out of her throat. "Jimmy, no. It's not your debt..."
You pick her up by the throat, squeezing gently as you look into her eyes. "You belong to me, little Zo."
"Oh...James...." she croaks, going limp and moaning softly.
"The only thumb you belong under is mine." Her eyes start to well up. "I'll take care of this."
She grips your wrist with her hand, rubbing your cock with the other. "Take me... I'm yours."
You spend the next few minutes fucking Zoe's brains out against the wall of the shower. While you pound her pussy, then ass, then shoot your load down her throat, you think about possible ways to deal with this. {if GeorgieFavor = 1
} Perhaps, after Georgie's business is taken care of, he might be amenable to a return favor. For the family. {else
} Whatever it takes, you're going to get her out of this mess. {endif

You stroke Zoe's her hair as she sucks your diminishing cock, getting every drop and rubbing your balls gently as they return to normal. "Thank you, sir." She kisses the tip. "Thank you for taking care of me."
"I love you, Zoe." You pick her up into your embrace, holding her tight, and she begins to sob gently.
"I'm sorry that I got myself into such a mess...."
"You were trying to help your husband, baby. It's not your fault that he's a lowlife." You rub her back.
You dry off, put on some shorts and a tshirt, and head downstairs just as Jenna and Karen enter. They're gabbing about the day they've had and the houses they've seen. You keep Zoe's predicament to yourself for now. Riley and Allison get home a few minutes later, carrying ingredients for tacos. Looks like they're going to be sorted for dinner.
At around 5:15, you start getting ready for a night out. You shave, get dressed in a nice pair of slacks, and a deep blue shortsleeve button up shirt. Jenna brushes out her hair and puts on makeup, wearing sheer knee high stockings under a tight dress, with a garter thong and no bra as far as you can tell. Your mouth waters as you watch her dress, and she winks at you as she clasps her nylons.

You head downstairs where Jack and Karen are waiting. The smell of tacos lingers in the air, and the girls are eating by the poolside. Karen's wearing almost the exact same outfit as Jenna, though she's clearly wearing a bustier under her dress.

"You guys ready?"
"Abso-fucking-lutely, Jameson!" Karen pronounces with gusto. Jack looks a little sleepy. He's probably still whipped from his encounter today.
Jenna comes down, and the four of you head out, taking an Uber so that you don't have to worry about driving home.
