A futanari isn't a futanari just by having a massive cock, balls, and an enormous pair of titties. The pussy is essential. Otherwise you are either just a very feminine looking guy with boobs or a girl with a massive dick. So you need to at least correct that area. But you are actually liking being in this body, so may as well just add the pussy and keep the rest, or maybe add more to it if you ever are feeling a little bit more, adventurous, that is.
Sitting down at your computer, you open up your profile and are about to add your pussy, when a kinky idea hits your brain. With a lusty smirk, you immediately proceeded with that idea and hit enter. It happens both quick and painless. And after only a few seconds, you are finished with growing in your "upgraded" pussy.
You get up a d head over to the full length mirror on your wall, feeling your new lower lips rub against each other with each step. When you get there, you turn around and bend over while spreading your ass cheeks. There it is, nestled right where your asshole use to be is your brand new pussy. However, this pussy is special. This pussy not only functions as a pussy, but also as your asshole too, and can fit your entire cock inside of it, including both of your grapefruit sized nuts.
"Ah hahahaha! Yes! This is perfect! Turning my asshole into my pussy, then making it technically a cloaca was the best decision. One hole to handle it all, and ow I can even store my meat inside of it whenever I want a smooth and flat look up front too! Ah you have out done yourself this time, Jazz." You say, realizing you just referred to yourself as Jazz, and not, not... well it doesn't really matter if you can remember your old name or not. You are not going to ever change back from this current reality anyways.
You unwrap your cock and begin teasing your new opening with your tip. Being able to move it around without using your hands is an amazing feature you are super glad you added. Especially now that you also can freely change its species. "Hmm, I wonder which kind of dick feels the best to be fucked by? Well, I guess there really is only one way to find out." You say to yourself plunging your cock right inside of you, and begin what is going to be a very long masturbating session. There are just too many amazing looking cocks to fuck. You are really looking forward to trying out a horse, bull, dog, cat and pig cock especially.
After 8 hours of straight nonstop fucking yourself, using 12 different shaped cocks too, you decide that your favorite shape is human surprisingly. Although horse was a close second, then pig. You are not a big fan of cat dicks though, as their barbs hurt too much, but they also made you cum the hardest too, which is why you were not outright against ever doing it with one again. You would really need to be in the mood though.
Well, now that a big portion of your day is over with, you may as well get a shower and clean up a bit too. Your belly is slightly bulging with how much cum is inside of your pussy at the moment. You hadn't realized just how much you came with a pair of nuts this size. It was really packed in their too, as you could feel what was essentially a hardened surface through your belly. 'Perhaps I went too hard this morning? Nah, it should soften up soon enough, right?' You think to yourself as you step into the bathroom.
You suddenly feel the urge to poop, and rush to the toilet. The moment you sit, a jet of liquid shoots out of your pussy and the feeling is gone. You wipe and look to see the inside of the toilet looks to be covered in bird poop. "Well, I did give myself a cloaca after all. I guess this is how it looks now." You flush and are about to step into the tub when a other feeling from your pussy hits you. You do not need to shit, as the feeling is very different, but something is definitely trying to come out of you. You can't even reach the toilet and end up squatting down on the floor.
Unlike your poop, this one takes a bit more effort to push out of you, and it is a lot harder. It takes you a good minute of constant effort, but finally you manage to get whatever it is out of you. Looking behind you, you are surprised to find a massive egg. It is about a foot tall and had to at least be 8 inches in diameter at its thickest. "Did I just lay a god damn egg!?" you loudly say, but before you can do anything else, that same feeling appears and your body instinctively squats down once again. This time it is not nearly as much of a struggle and only takes roughly 10 seconds to push out your second egg. This time, it feels pretty pleasurable. The process only quickens from there and the pleasure raises quickly until you are orgasming with every egg you lay, as you continue to lay another, then another, then another.... until you are sitting in a small pile of about 9 eggs. Well, that certainly explains the odd hardness you felt in your belly. "Right, cloaca... of course I lay eggs now."
