You think you've been your mom's pussy for about three hours now. It's hard to be entirely, since pussies don't have access to clocks or watches. But you're actually quite enjoying the experience. For some reason, you quite like it when your mom walks. You really like the feel of your mom's silky smooth thighs brushing past what used to be your cheeks, though they now seem to part of her outer labia. You know your mom isn't at home anymore. After finishing chopping the vegetables, she spent some time preparing dinner, and then she went out.
You heard the front door open and then close, then your mom walked to her car. On getting in, you felt an immense weight on you as she sat in the driver's seat. It wasn't painful, but you can't say that you really liked the experience. After a relatively short drive, your mom got out of the car, and walked for several minutes, you then heard the slightly muffled, but recognisable voices of two of your mom's friends, Carla and Simone.
Apparently, they're at the mall. They spend what seems like forever walking as they visit various store, and then finally you feel your mom's immense weight as she sits down on what seems to be a hard chair. You assume that she and her friends are at a café or something. After about an hour or so, you feel an odd sensation in part of your throat. It's as if it's filling with water. At that point, your mom and her friends start moving again. A few minutes later, you hear a sound you can't identify followed by what sounds like the door to a toilet cubicle being closed and locked.
The next thing you know, your mom pulls down her panties as she sits down on the toilet. You then feel a strong flow of water surge down your throat and come out what used to be your mouth. Fortunately, you can't taste your mom's urine, which you're very grateful for. You can actually see the yellowish liquid falling down into the water of the toilet bowl. From your position, the sound is almost as loud as Niagara Falls. After a minute or so, the flow stops. A few seconds later, a giant appears with a piece of toilet paper and wipes what used to be your mouth. Your mom then stands up, pulls her panties up and then leaves the cubicle. After washing her hands, she leaves the rest room.
She then heads back to her car and drives home. About 20 minutes later, your mom gets out of the car, and as she walks, you hear the muffled sound of the automatic garage door closing. She goes into the house and heads upstairs, presumably to her bedroom. She stops walking and a couple of minutes later, she takes off her skirt and panties. She then puts on a pair of dark blue bikini briefs and goes out to the pool in your backyard.
The next thing you know, you feel what you think is your mom jumping, and seconds later you find yourself immersed in water with your mom kicking her legs as she begins to swim. For a short while you find yourself panicking due to your being underwater. It quickly recedes though, when you realise that you're not breathing. It's at that point that your inner voice says;
'Your not human anymore, you're a vagina. And vaginas don't have lungs'.
Your mom spends about an hour or so swimming before heading back into the house and taking a shower. You guess that it's somewhere around mid to late afternoon. The next few hours go by pretty slowly, She goes to the toilet once more, and shortly after that, you're pretty sure that your mom, and the rest of the family sit down to dinner. During that time, you're pretty sure that you can hear your own voice. At first you find it pretty odd. Then you realise that your mom must have made a copy of you to avoid answering questions on your whereabouts. Though she could just have easily claimed that you were at a friend's house.
As the evening gets later, you begin to think that your worst fears won't be coming true, but you're wrong. It starts with a light pressure on you while your mom is stood up. You quickly realise that it's your dad pressing himself against your mom. They must be kissing or something. They quickly strip each other's clothes, and you find yourself staring, with a deep sense of dread, at your dad's enormous erect penis. Your parents then move to their bed and lie down, with your dad half on top of your mom.
After a few minutes, his right hand comes into view and his middle finger gently starts to rub your nose, which is now your mom's clitoris. From somewhere above you, you hear your mom let a soft 'mmm'. Not long after, you feel your lips involuntarily push out, much like the inner lips of a vagina would. Which is actually what your lips are right now.
To your surprise, your then suddenly lifts his hips and slides on top of your mom. You feel his hard cock press down on the top of your head, which is now your mom's Mon's Pubis (pubic mound). It feels like a one thousand ton steel girder is resting on your head. Directly in front of you, pressing against your lips and what used to be your face, are your dad's enormous balls. Suddenly, your parents roll and your mom ends up on top. She quickly slides down your dad's body, and shortly after that you hear him groaning softly. It doesn't take you long to work out that your mom is sucking your dad's cock.
Several minutes, and much groaning later, you hear your dad let a long, loud groan and then fall silent. Eventually, your mom slides back up and you once again find yourself with a face full of your dad's cock. This time though, it's covered in a layer of your mom's saliva. They start kissing again and then roll over once more so that your dad is back on top. Although not painful, the weight is immense, like having a skyscraper lying on top you.
Finally, the moment you've been dreading arrives. Your mom slides her right hand down your dad's body as he raises his hips. She wraps her fingers around the enormous shaft and pulls it down until the glistening purplish head is pointing directly at you. You can't help but feel horrified as the giant cock head presses against your lips and slides inside as they part. You briefly wonder if your dad knows that you're currently your mom's pussy. If he does, he has done or said anything to indicate it. It's difficult to say exactly how big your dad's penis is. You estimate that it's about ten inches long and about three inches wide. The walls of what used to be your mouth are stretched wide to accommodate the large girth of your dad's penis as he slowly slides it in deeper and deeper. You can clearly hear your mom and dad groaning as he slides his cock in.
After a couple of minutes, the entire length of your dad's gigantic penis are in your mouth/mom's pussy. It feels somewhat uncomfortable, having it stretched so wide around the massive cock, but there's nothing you can do about it. After about a minute, your slowly starts pull his cock out until only the head is left inside. He then slides it back inside, which causes both of them to groan loudly. Over the next few minutes, your dad thrusts his cock in and out of you at steady pace. Your mom in particular is very vocal, and her groans of pleasure are noticeably louder than your dad's.
After a while, the groans get faster as your dad starts thrusting faster and harder. He does this for several more minutes, and then your parents suddenly roll over until your mom is on top. She then sits up and begins sliding up and down on your dad's cock very hard and fast. You're feeling quite sick now, and trying hard not to think about the fact that you're dad's enormous, rock hard penis is sliding in and out of what used to be your mouth. You feel quite angry, both with your mom and yourself. Though your mom did warn you that she would be treating you as her vagina. You've decided that this won't be the last time that you wish to be your mom's pussy, but it will be the last time she has sex while you're a part of her body. You'll make sure of that.
Several more minutes later, you're not sure how many, you suddenly find yourself upside down as your mom gets on all fours. Your dad's cock has been withdrawn, which provides you with a short respite. It's not long though, before you see the enormous, purple head flying towards you, before forcing your lips apart and sliding deep inside. The thrusting is now incredibly fast and hard, and you find yourself feeling grateful that you can't feel pain. The groans and moans are louder and faster too, and your parent's breathing is also getting faster. You can feel a build up in fluid in your mouth/mom's pussy, and with a sense of dread, you realise what's happening. After what seems like hours, of your dad fucking your mom from behind, the thrusts become faster and harder than they have been so far. Suddenly, you hear both parents let out long, loud howls of pleasure as your mom's cum suddenly fills you up. Worse though, is that your dad plunges his cock in hard and holds it there. You feel it start to twitch and then, to your horror, it starts to pump out a warm, thick, salty tasting fluid. You know instantly that it's his semen, and it makes you feel even more sick.
You can hear your parents panting, and feel the sickening fluid dribbling out you. After what feels like hours, your dad finally pulls his cock out and your mom lies and rolls onto her back. After a long time spent kissing and cuddling, they finally fall asleep.
