The doorbell rings.

The doorbell rings. You all freeze and ignore it. Then theres a knock on your door.

"I know you are in there! I'm going to call the cops if you don't open up!"

You all exchange glances, and then you all put on the clothes you were wearing. You open the door.

"Hi," you begin.

"Alright," Mrs. Barstone huffs as she pushes her way in, "where's the man of the house? I havn't seen him for days. Oooh," she then moans as she sees the two large dicks which can't be hidden under simple dresses.

"I am actually the owner," you state flatly.

"Oh...well I didn't know," she dismisses, "But now that I'm here, would you mind if I played with these huge dicks on your friends here? You see, I have had many kids, and I'm quite stretched out down there."

"Oh...are you? Well, I've barely had time to enjoy them myself."

"Oh, please, I'll do anything!" She looks ****.

"Hmm, well if you want, I'll trade you two for two. I've noticed your two eldest daughters lately. I'll trade free access to Candice and Monica for the same of your daughters."

"But...they have college today...fine...deal. I'll call them over now." Mrs. Barstone gets out her cell, and makes a call. "Hi, Judy, it's mommy. Get your sister and come next door. Oh, and wear something sexy like I do when me and your father fuck. Ok, see you soon." she hangs up. She sees your quizzical eyebrow. "Yeah, I did let them watch me fuck my husband. Better they watch at home than need to go find some boy and get knocked up."

"I see. Well a deal's a deal."

"You are Monica? Let's go." Mrs. Barstone takes her by the hand and pulls her to the livingroom couch. You watch as they get undressed and start the foreplay. Then your doorbell rings again. You open it to find a redhead with small tits but wide hips and ass dressed in a long t-shirt and a slightly taller but extremely busty brown-haired girl wearing a bathrobe.

"You have good taste in underwear," the redhead tells you. She pulls up her shirt to reveal she is wearing the same style of lacy bra and thong as you. Hers also has a bulge in the crotch. "Footlong clit," she states with a smile and pulls her front down to flash it at you. "I'm Violet, and this is my sister Judy."

"Hi, can we come in?" You move out of the way and they enter and you close the door behind them.

"Could you girls undress me?" Violet pulls her shirt completely off and Judy undoes her robe to reveal a skimpy see-through bikini.

"Don't mind if my clit pokes you. I have the same pregnant fetish as my mom."

"Even to yourself?"

"Yea, you do too, I see," she says with a hand on your belly.

"That's actually another of those big girls," you admit. "I'm actually a guy."

"You don't say," she tells you as she runs her hand to your crotch.

"You have anal sex with those big dicks?" Judy interrupts. You nod. "That's so hot! I want a big dick up my ass too!"

"It isn't easy..." you begin.

"I have stuck big things up my butt before," she admits and blushes.

"Like my fat clit," Violet deadpans. "She molested me in my sleep the first time. I must have been having a nice dream; my covers had gotten thrown off, my nightgown had ridden up, and my clit was fully engorged and must have been standing straight up. So of course we are the two that share a room. And of course my dream had me all wet and lubed up. So I wake up and see my butt naked sister impaled halfway down my clit with her hands up my shirt! And that's before I noticed I'm not in her pussy, but her ass! So anyways, I'm like totally shocked! She has her eyes closed of course so I'm just like watching. I'm not like disgusted, her ass does feel nice, but I'm just surprised she would jump my girlbone. I thought I would have a hard time finding someone to tolerate my freakishness. But here is my own sister not just tolerating it, but putting it up her butt and enjoying it! So I watch for a bit as she sort of rises and falls as she sort of fucks herself lower. Her big boobs jump and sway and I'm just turned on as all hell. A girl, and my own sister, right? Kinky. I want to do something, but what if I scare her off? I should just play asleep, and every night lay there with my clit out to entice her? Maybe be totally naked? I don't know what to do so I just watch, but she stops before her butt even touches my crotch. She works at it a bit, but she doesn't make any more progress. She starts pulling off and then for some reason I grabbed her hips! Oh boy, did she get scared. But then I quickly told her I was having fun, and wanted to bury my whole length in her butt. I grabbed her cheeks and spread them wide. They didn't used to be that big, but after pounding her ass every night, she has a plump one now. But anyways, I helped her fit the whole thing in. And we made out once we stuck it in. But then she started fucking me as she lay on top, and she started sucking my nipples. They are pretty big too despite the B cup titties. So anyways, Judy's tits are big as hell, so I yank those bitches up and they're actually big enough so I can suck her nipples too. We didn't just cream once, we went all night. That room smelled like pussy and still does cuz we still fuck at least once a day!"

By the time her long story is over, Violet has you naked and is rubbing your dick. She then goes down on you briefly, almost making you nut. You are just standing there as Violet wraps her legs around your legs, and slowly hoists her crotch up as she sort of stands on her head. Her crotch eventually finds your dick, and she guides it into her pussy. As she slowly grinds into you, she continues talking.

"So our mom figured it out pretty quick. She never really came out and said anything, but started teaching us about cocks and pussies and all of that. And then we started getting an extra allowance for our "needs" via a credit card so we could buy stuff online too. The first thing we did is hit the lingerie stores. We bought a ton of stuff. Crotchless panties, see-through bras...just tons of stuff. Then every night we modeled something new for each other after everyone else was asleep. And then one thing always lead to another...we aren't gay or anything...but you understand that better than anyone, huh?" At this point, you cum hard. Violet squeels. "Mmmm...ahhh! Oh wow...wow...yea get me pregnant. I hope you got another load for my sister. These fertility **** better knock me up with quite a few babies! I want to be huge like you!"

"Well, I had some help. Candice, you are the same base model as Kako, right? How about you help Violet a bit?"

"Mmmhmm, I don't know how fertility **** will interact, though. I guess you wouldn't mind sharing underwear though, would you?" She is already masturbating, knowing the answer. "Not many targets with you two still connected."

"Just don't get any on me," you caution her.

She aims below Violet's bra so the cum flows over her breasts since she is standing on her head still. She shoots.

"Holy Crap, that's a lot of cum!"

"Not as much as she can muster normally."

After cumming, Candice steps back. Violet's breasts go fom B's to C's in under a minute. Then they go to D's in another. Gravity pulls them down, but the bra holds her large nipples inside. Eventually, her breasts grow under it too. In but 30 minutes, Violet has breasts about the size of Kako's. The bra holds tight.

"Wow, oh fuck." Violet's crotch is grinding against you. "You fucking rock!" This time, you grab Violet and fuck her back in the short time before you unload again. After you finish, Violet pulls off of you and stands up. Her bra is squashed into the middle of her cans. She shakes her chest. It stays in place.

"Looks tight," you tell her.

"Mmmhmm, want to take it off me?" She turns so you can. It slingshots off and lands on the shelf of her sister's chest. Her breasts balloon out, and settle into place. "How do I look?"

Judy slides the bra between her titties, "I'll let you find this later," she smiles.

"Top-heavy," you comment. You tweak a fat nipple and get a squirt of milk! "Big fat titties that give milk, how original." You lean down and pull a nipple into your mouth. "At least we all have a distinct flavor. See?"

Violet sucks you, then herself. "Yea it's different. So what?"

"Who's do you like better?"

"Mine, of course! It's so creamy!"

"Mine tastes sort of like cum," Candice offers.

"You people suck your titties all you want, I need a dick up my butt! That big one there!"

"I can't take that log," you state.

"I will soon, I just need some of that special sauce!" Judy stretches the leg of her panties around Candice's cock, and then grinds her butt all over it. The girth parts her cheeks so wide you can see them wrap around the big dick.

"Ok," you give Candice permission to loose what she has brewed since her last orgasm. Judy's soft round butt gets rounder and softer...and bigger. That's about twice as big as before, you think. The waistband drops lower, exposing her deeper crevase. It also pulls tight in between her legs, giving her a beautiful camel toe.

"I can feel myself taking more already," Judy tells Violet.

You lay down on the couch and gesture to Violet. "Come here, let me lick your ass to prepare you. You can fuck my tits while I do."

"Prepare me for what? I don't want to take big dicks," she complains but sits on your face anyways. "Ooohhh, that's not bad. Oh, yea, put your tongue all that way up there!" She soon is getting it on both ends; her clit pushes between your tits, and when she pulls back, you push your tongue in her ass.

"Are you going to share, Judy? I like all my girls to have big butts," you manage to say when your mouth isn't servicing your new busty friend.

"There's not going to be a lot for you this third time. I will need a break after this too, I need some time," Candice informs Judy.

"Fine," Judy groans. "Hey sis," Judy says as she hops on your big cans without complaint from you, "How's this look?" Judy pushes her panty-clad butt back in her sister's face.

"Stop rubbing cum on my face," she mumbles into her sister's ass. She pulls her face back and yanks down the tight panties. She tucks them between her boobs. "I'll let you find these later," she mimics.

"Why don't you take a seat on a nipple, Judy?" you suggest.

"I guess," she says.

While they are both occupied, Candice sneaks up behind Violet, jams her cock between her cheeks (which you moistened) and squirts a little bit.

"Hey! Damn, you distracted me!" Violet's butt doesn't grow as much, but it still ends up almost as big as Judy's due to how big it was to start. Her thong disappears fully between her larger cheeks.

You smack her butt. "How about you hop your nice big ass over to my other nipple, and put it up your butt," you suggest.

"Jeez, I guess I don't have a choice now." They both work your long thick nipples into their asses. Violet is new, but she picks it up quick since you warmed her up. After a few minutes, both girls are spreading their cheeks as they bottom out on top of your boobs.

"You girls are as talented as me," you tell them with admiration. "What are you waiting for? My boobs are bouncy, go ahead and fuck yourselves!" They smile and raise and lower themselves. "Don't forget to flex your muscles."

Once they start fucking and clenching their muscles, you feel relief.

"Uhh!" Violet exclaims. "Are you lactacing? Up my butt? You pervert!"

"Haha," Judy laughs. "These big titties need milking. Why did you think we were fucking his nipples? Come on, it's totally hot!"

"It feels strange. There's so much! Ugh," Violet groans.

"Don't be a baby, I'd let you stick your udders up my butt."

"Really? Oh."

"Just relax and let his milk have its way with you," Judy tells her sister as she rubs a growing bump in her middle. Violet looks wide-eyed at her sister's middle. "Did you think titties this big made only a little milk? Plus by how fast he started, he hasn't been milked all day, right?"

"The one you are on hasn't been, but Violet's has been sucked a little before your mom interrupted."

"Damn, what have I gotten myself into," Violet mutters as she resumes milking you with her ass. They both are going to take every drop you have.

As they do that, you ask Candice, "Can I see your ass?"

"Sure, honey," she says as she climbs onto the couch and squats over your face. Her balls rest on your forehead as they hang down. "See anything you like?" She flexes her asshole for you. It looks like a regular one.

"It doesn't look like mine, but yes," you tell her. "I guess you just stretch a lot," you conclude before she lowers her hole onto your mouth. She knows that she needs to rise up often so her cheeks don't smother you.

"We need a double-ended dildo to share," she notes. You give a muffled 'yes'.

As you eat out Candice's ass, you notice another impact point growing more pronouced with eat passing minute at each rise and fall on your tits. The bellies on those girls must be filling out nicely.

"Phew, that Mrs. Barstone finally passed out," you hear Monica say as she walks in. "Mmm, look at everyone! Looks like I'm gonna give you a blowjob and fuck your ass so every sexy part of you is taken care of!"

All you can see is the undercarriage of Candice, but you feel a dick start plowing between your cheeks as a mouth lands on your dick. You nut the moment her mouth fully wraps around it.

"Ohhh," Violet moans, "you are spraying so hard. Are you cumming? You squirt more milk when you cum, wow. I can't believe how big my belly is! I bet Judy is looking forward to fitting your whole boob up her butt so she can milk you all day long. Mmm...or even better, both of them. I bet she can't wait to get big enough to put Monica in her."

"Heh, and I'll put real babies in her pussy, too," you mutter into Candice's asshole.

Judy isn't paying attention. She is grinding her clit into your supple titflesh. Candice heard you, though.

"Monica, looks like you have been claimed by Judy here. It's going to be a chore fitting inside Violet with Ariel still inside of me."

"No thanks! Really, it's fine! I don't need my ass worked that loose!"

"More for me then," you mutter again into Candice's ass. Again, she hears you.

"Really? Your proportions would have to be silly to take me in my current state with Ariel still inside me."

"Sure," you retort.

"Your ass would need to be big enough to fill this entire couch. Your hips would reach end to end. Your thighs would be literal tree trunks."

"Sounds like more of me to love. And I need to retain my size crown."

"Wait, no way! If you get bigger, that would be wierd. Fine, I'll do it," Violet says with surrender. "You better be there to milk me," she says to nobody in particular.

"I'm good at milking with my ass," you and Judy tell her almost simultaneously.

"Good, cuz I got two big tits that are gonna get bigger," she reminds you both.

"You heard her, Monica," Candice tells her companion.

"I was just making sure our host was well-attended," Monica reminds her.

"My tits feel better now, thanks girls! Candice can you get off of me please? Thanks." You take a look and see both girls have great distended bellies resting on your breasts. They took a fair amount of volume from your chest, you notice. Every ounce is hanging from their fronts, though! "C'mere Violet, I'll drain your ass so your stretched belly has room for Monica's cum."

Violet slides up and off of your nipple. Immediately, a stream of yor milk starts squirting out of her ass.

"Ugh, I can't hold it! I'm shitting all over you! It feels too good to stop! I'm so sorry!"

"C'mere, it's just milk. Anything else is so diluted I won't taste it."

Violet crawls over you and turns around so her milk stream aims at your face, then backs her wonderful ass to your mouth while you guide her with your hands on her hips.

"Oh, wow, you are drinking from my ass! Mmmm...you will do anything for me. This may not be so bad after all!"
