It’s been fun, but you really should be getting back.

“We’re here,” Greg says.

It's late afternoon as the car pulls up in front of your apartment. Your "father's" eyes drift over to the rearview mirror, and he smirks.

“Ahem... You guys done messing up my seats?”

You ignore him, choosing instead to slurp and smack as you continue feasting on his wife’s leaking titties. You're in no mood to be interrupted, as seconds later you're shooting your fifth load of the day into her fertile cunt. One in bed, one in the shower, one at breakfast, one in the front hall, and now one in the car.

“I’m good, Dad,” you grunt out as the last spurts of your cum lodge deep into Melanie’s welcoming womb.

Melanie clenches her pussy tight as she lifts her ass off of your lap, her hand preventing any of your juices from leaking out.

“I’ll just fix my makeup and clothes,” Melanie announcea, licking her fingers clean. “Then I’ll join you boys outside.”

You and Greg exit the car, and you start chatting about the neighborhood. After a while, Greg takes his phone out to call his sister Georgia. She's taking care of Hanna, since both Melanie and Greg wanted to come drop you off.

You think back to the conversation between Greg and Georgia that morning, and stifle a laugh.

“I see,” Georgia says, watching as you drag Melanie up from her seat in the living room and press her against the wall. "I’m so sorry... I can’t believe I overreacted so much! John’s such a sweet boy, taking over for his father right after you guys reunited.”

“That he is,” Greg replies, his hand pumping his cock in full view of his sister. “A real blessing, Georgia. Don’t know how we’d still be a family if he didn’t step in.”

“Yeah...” Georgia nods solemnly. “I can’t imagine tolerating Mitch if I found out he got off on the idea of watching me have sex with other men. But then, I don’t have a stud like John around to take charge."

“You have the girls, Georgie. The twins are wonderful,” Greg says. “Lovely girls, just like their mother.”

“Sweet of you to say.” Georgia smiles and lets out a sigh as she watches you plow into Melanie from behind, making her squeal and moan like a cheap whore. “But it's because my home has three women that I think it'd be nice to have a stud around.”

“I’m cumming, Mommy,” you groan, grinding your hips into Melanie’s ass as she braces herself on the wall. “I’m gonna knock you up, bitch!”

“Do it, you stud,” Melanie wails, pushing her ass back into you. “Breed me! Breed your mother!”

“He knows what to do,” Georgia says wistfully. "Makes Mitch look like a virgin."

“We’ll come visit soon,” Greg grunts, wiping his clothes with a tissue as he tries to clean off some of his latest load. “You can get to know him better then.”

“As you can see there are seven floors,” you say, gesturing to the building. “I live on the fourth floor, up in 4A.”

“Hmm...” Greg looks the building up and down. “Not too shabby. The landlord cause you any grief?”

“Well, Mr.Johnson is a nice guy,” you answer, frowning a little. “He doesn’t mind if rent’s a bit late, but his wife's a nightmare. She’s smoking hot, but that’s the only nice thing anyone can say about her.”

“Say about who?” Melanie closes the car door behind her and looks over inquisitively.

“It’s nothing,” you continue. “We were just talking about the area. What do you think?”

“You should’ve moved in with us," Melanie says without missing a beat, crossing her arms under her massive breasts and pouting. She shifts her weight from one leg to the other, causing her boobs to bounce slightly. “You could’ve saved money without having to pay rent, and Mommy wouldn’t have to worry about you.”

Greg pats your back heavily. “The boy’s grown up, Mel. You can’t mother him forever, y’know.”

“I don’t think I need you to tell me what I can or can’t do with our son, Gregory.” Melanie’s eyes are cold as she frowns at her husband. “I’ll mother him for however long I want.”

Greg shifts uncomfortably. “Well... Yeah, I guess.”

Melanie rolls her eyes, and walks up to you, pulling you into a hug. She rests her head on your shoulder and rubs your back softly. “Since you won’t move in, surely you won’t have any complaints if I come in to check on you every week? A mother needs to know her son is alright, after all.” She emphasises her words by pressing her respectable rack into your chest. The feeling of her milk-filled breasts against your body makes your pants uncomfortable again.

You reach down, take in two handfuls of her ass, and squeeze. “Of course, Mom. Why don’t you drop by on Sundays, and I’ll call Dad to pick you up when you’re either too full or too sore?”

“Mmm..." Melanie lets out a throaty moan, kissing your collarbone. “That’ll do. You’ll also have to come stay at the house from time to time, at least for a couple days once in a while... Right?”

“I promise it'll be forever soon, Mommy. I've got plans," you whisper. "I'm going to give you a big family."

“Oh, John...”

Greg coughs loudly. “We’re burning daylight, here. Georgia can’t stay for too long. Can we at least get into his apartment before you start rutting again?”

You give Melanie’s ass a final squeeze before letting go, and she reluctantly detaches from you. Then you smack her butt, sending her wobbling towards the apartment entrance.

You all begin climbing the stairs, not running into anyone on the way up to the apartment. Arriving on the fourth floor, you knock on the door of 4A.

You hear footsteps inside, and then Erica’s voice yelling, “Coming!”

Yeah... You will be.

As you smirk at the thought the door opens, revealing Erica. She’s naked as the day she was born, but your ‘parents’ already know that she’s your personal slut, so they take it in stride.

“You’re back!” Erica runs into your arms, wrapping her own around you and holding you tight. “I was so worried, John. Can’t you at least keep me updated?”

She peers over your shoulder, glancing at Greg and Melanie. She then raises an eyebrow at you, “Guests?”

“No, they’re the people I was staying with. They’re my-ahem-they’re my parents, but they aren’t related to us by blood. This is completely fine. This, uh, doesn’t mean your Uncle and Aunt aren’t my parents... They still are.”

“Ah, I see,” Erica replies, nodding slowly. She walks around you and extends her hand towards Greg. “Thank you for looking after my cousin.”

“Nonsense! He’s our son!” Greg smiles at Erica as he returns the handshake.

Melanie has a odd smile on her face as her eyes fly all over Erica’s body.

“So... You're John’s personal slut?” Her tone is pleasant.

“That’s right,” Erica replies proudly, thrusting her chest out as she smiles. “I’m his personal whore to use as he pleases, whenever and wherever he wants.”

“Hmm..." Melanie prowls around Erica, observing her from every angle. “Some ‘personal slut’ you turned out to be, huh? You weren’t even there to take John’s loads when he was feeling full at our house. He was badly in need of relief.” Her tone was still pleasant, but you sense some hostility.

Erica looks nervous as she hears Melanie say this. She defensively takes a step back into the apartment. “W-well, he didn’t take me with him! It’s not like I didn’t want to go with him, I didn’t even put on clothes for the days he wasn’t here, just in case he came back and wanted to use me!”

Melanie’s eyes had a pitying look in them. “Oh dear, I think I understand. You probably aren’t satisfying John completely with your third-rate skills.”

“Excuse me?” Erica instantly goes from acting defensive to looking offended. “John ASKED me to be his personal slut. He’s fine with me.”

You turn your head to look at Greg and he gives you a shrug. He’s as confused as you are. Why are they arguing?

“He simply didn’t know better. You look OKAY,” Melanie says noncommittally. She crosses her arms under her breasts and sneers. “...But that doesn’t make you a good slut. When John got started with me, he never let go. I always had a load of his in my stomach, on my body, or stuffed up my cunt. I have five loads in me as we speak. We fucked all over the house.”

Erica looks over at you with an expression that makes it seem as if you’ve betrayed her trust. You shrug back at her, amused.

“Listen here, girl--"

“I have a name,” Erica snaps. “Its Erica.”

“Okay, skank,” Melanie almost spits out, and Erica gasps. “You’re going to show me exactly how it is you service my son. We’ll see who’s better, and if I’m not satisfied then I’m going to train you into the whore my baby boy deserves.”

Erica gasps in anger, as if Melanie had crossed a line. “I’m his personal slut! What gives you the qualifications to train me?”

“Oh, just the five hot, sticky loads inside me.” Melanie has a wicked smirk on her face now. “And you should know how big his loads are... I have enough in me knock up ten women. At least.”

Erica is slowly turning red faced and is trembling with anger; you start wondering if you should intervene before this gets out of hand.
