???

It is still early, there's no way Mrs. Barstone could be here yet. Then again, she might be really horny. You quickly wipe your lady's semen from around your mouth with a towel, and open the door. Then you stare, shocked at the sight.
You see a redhead, about 5'8". Cute face, lovely emerald eyes that you can't help but get lost in. She smiles and says, "Hi, I'm Jennifer! I'll be staying with you for a while!" Her voice is melodic.
"Uh," you begin, confused.
"You ordered me," she responds. You immediately understand. There must have been some mix-up, and your order was duplicated.
"Oh sorry, but I already have someone. Kako arrived yesterday about this time."
Jennifer seems undeterred. "Oh, you haven't checked your e-mail lately, have you?" She gives you an understanding look. "Of course not, silly me, you must be having too much fun with Kako, you only just got her. Your order had a tagged on bonus. Me and Kako are the only two of our model, and rather than have me sit around taking up space, they decided to discontinue the model completely and ship us both out when someone finally ordered either of us. I would have shipped out with Kako, but I needed a few upgrades to the most current technology since I was made over a year prior to Kako. My skin darkened a bit with age, but the newest technology has repaired that problem. So I am creamy white all over," she concludes, flashing you a charming smile.
"Wow, um, I am really not sure what to say," you stammer. You already have Kako, and she is already more than you can handle. Finally pulling your eyes away from her face, you glance over her figure. Her breasts are large, larger than Mrs. Barstone's preggo tits. They are contained in a blue spandex top, which does nothing to hide her two inch long nipples. They are rather thick too, about the size of your thumb. Noting the difference, you venture lower, and view her bare midsection, which is creamy white and looks very soft...that is to say what you can see of it, since her breasts hang down a good foot or so. A spandex top will not support breasts that massive. She is wearing blue spandex shorts, which you cannot help but grin at. The shorts are stretched beyond capacity in every way imaginable. Her ass looks delicious, a lovely bubble butt, which sticks out a good foot from her back. Seeing this, you assume that Jennifer was some kind of test model; they were probably seeing how big they could make everything. Her ass is pulling the waistband out a good 4 inches, and her ass cheeks overflow from there. Her hips are wide, and go well with her ass. Her legs are toned and muscular, more so than Kako, since Jennifer has to carry all of this extra weight around. Continuing on, you come upon her monster cock, which runs down the left leg of her shorts. The shorts, however, only come to mid-thigh, but the rest of her cock runs out and hangs there. It truly is massive. At least 50% thicker than Kako's, and probably 6 inches longer as well, it almost hangs to the ground. Her balls hang down below her knees. They must be larger than a watermelon...each! You look up at her.
Jennifer's smile widens, and she walks closer to you. When you opened the door she was standing a few feet away, so you didn't get the pleasure of seeing her walk until now. Her long cock bounces off of her legs, swaying with her step. Her enormous jugs merely ripple with her step, being so large that they are unable to bounce like normal-sized breasts. Even Kako's bounce when she walks, as do Mrs. Barstone's milky orbs. Jennifer's must have broken that limit. Their different movements are enticing to watch, but you look elsewhere. You see her testicles sway and jiggle as she walks closer. You hear a pop suddenly, and are only half-surprised as another follows. She stops suddenly, not moving. You deduce that a few stitches have broken in her over-filled garments.
She giggles, a lovely musical sound. "Oooops...I was hoping these would hold. They increased some of my dimensions yesterday while they were repairing my skin issue. Of course, since they were just trying to get me in perfect condition before shipment, all they cared about was my working order. Customer satisfaction and all that. They were too cheap to give me new clothes to contain my...self," she looks around at herself, clearly distraught. "Can you help me find out where I am too much of a woman to be contained by these cheap...rags," she asks, looking at the all-too-small spandex which isn't even hiding everything to begin with.
You gesture to her cock which looks more the size of a leg than her real leg which is right next to it. "Ah, I hate to tell you, but you are already exposed."
She looks down. "I am terrified of being exposed in public. That problem there cannot be helped for now. It took over an hour to work up the courage to get out of the car that brought me here, because of my little length problem. I don't think I could deal if something else happened."
"Well, that's the most massive little problem I have ever seen," you comment.
"It really isn't, as long as you don't keep directing my attention to it..." she then gets the joke, "Ah, you have a good sense of humor. Yes, it is 65% larger than Kako's dimensions. Thank you for the compliment." She lowers her voice. "I can't wait to get it in you! I see Kako has taken you already," she points to some cum that you missed which is running down your right leg, "so you should be stretched well enough to start training with me now. I am surprised though," she grins, "the estimated time to train an ass to handle Kako is 3 years and 4 months for a male. You must be very talented indeed! I promise you, even though me and Kako together cost only 10% of what the other models cost, you will get the most bang for your buck...both receiving our heavenly cocks and us providing a warm tight home for yours." Jennifer eyes you knowingly and slaps her right ass cheek, causing it to wobble beneath her flimsy shorts. "You like my extra large ass?" She slaps the other one a bit harder, causing her cheek to roll and collide with the other deliciously. "But," she straighens up, a pleading look on her face, "only once we are inside. Please find out where the material is breaking!"
You decide not to mention there is no way you are taking Kako's monster cock inside you, and definitely not Jennifer's impossibly huge penis, even though it is as lovely and oversized as the rest of her fun parts. You nod, and move up to start inspecting the seams. You start from the top down. You inspect the seams of her shirt, hauling up her tits one at a time to check underneath. They are really heavy, but everything is holding there, you check the back of her shirt and notice her well defined back muscles. Probably so she can walk around with those massive things hanging off of her chest. "Top is fine." She sighs in relief as you continue to her shorts. You start at the front, running your hand along the waistband and then the inseam. You trace down her ballsac, and she jumps at your touch, causing her to jiggle. You hear another pop, but don't catch exactly where it came from. You move around back to examine her, and start from her waistband, which is quite far out from her waist, and you think you will find the popped stitches there. You are wrong. You trace down the inseam down on her ass, pressing against the fabric hard to feel for any holes. You trace down the inseam between her lucious ass cheeks, and find the problem suddenly. Your finger slips inside her spandex shorts, right up into her asshole! Jennifer jumps at the sudden penetration, and your hand inside the pants causes it to tear along the inseam right up to the waistband above her ass.
"Oops...well, if you wanted to play I DID tell you to wait until we were inside," she chastens.
"Actually, I found your hole," you reply, annoyed. "Now you have gone and tore through the entire back end of your shorts, your ass is sticking out for the world to see."
Jennifer turns beet red all over, even her ass. "Yes, I felt you find my hole! But all I wanted was for you to find the hole in the spandex! Quickly, cover me until we get inside!" She pulls you into her. Her ass feels lovely, and your already hard cock is nestled in the softest ass ever. You pull out your cock for what you guess is going to be a fun walk inside. "Hey, what are you doing? Let's go!" She walks slowly, allowing you to keep up. You do your best to cover her expansive ass, but it is hopeless. It would take a 500 pound man to be able to block the view of her ass normally, and you are squished up against it, pushing it out to the sides. You do your best, and put one hand on each side of her ass. Your cock feels wonderful, and you decide to enjoy yourself even more, and enter her twitching hole. "Hey, not until we're inside, I said!" She keeps walking slowly though, apparantly believing she is no longer exposed.
You finally get inside, and allow yourself to cum up her ass. She simply stands there, apparantly waiting for you to finish and pull out. Jennifer turns to you.
