A folded pink latex blow up doll is sitting in the box, along with an instruction manual. You blush and take the doll out. From a cursory glance, it seems very well made, with no seams or stitches. The manual says, "To inflate your PleasureDoll™, simply blow into the doll's mouth and use at your leisure. Deflation occurs automatically once the user is finished." It occurs to you that this seems rather impossible - the air would just escape once you take your mouth off, and how does the doll know when exactly to deflate? Nonetheless, you stick your mouth onto the doll's O-shaped lips and puff, slowly inflating the sex toy to a good size.
Now that the blow up doll is inflated, it folds of its own accord into the standard sex doll position - legs spread, arms in a wide, hugging angle, and naughty bits exposed and ready for use. You strip off your clothes and straddle the doll, gently inserting the head of your penis into the doll's latex vagina to get a good feel for it. The bright pink rubber is strangely warm and moist, almost like a real vagina, but when you pull out and take a look inside, there's nothing out of the ordinary. You shrug, and start pounding the latex blow up doll. The thing is so warm that it feels almost like real sex, and you're so engrossed in fucking the doll that you barely notice when it grabs you around the waist and pulls you in for a kiss.
Your mind pops out of its lust-addled frenzy to see that the sex doll is apparently alive, and is french-kissing you in a passionate embrace. You start to pull back, but its arms are surprisingly strong, and you can only struggle as it rolls over, so that you're on the bottom and the blow up doll is on the top. You try kicking wildly, but the doll wraps its long legs around yours and starts thrusting its hips and rubbing its large breasts on your chest. The doll pulls its head up and moans in lusty ecstasy, and you take the opportunity to glance down at yourself to see that the doll is oozing a think, pink slime onto your body. You scream in fear and confusion, and the horny rubber woman smiles at you. It croons in a smooth, sultry, incredibly sensual voice, "Mmmm, do you like that, dear? You're going to be a sexy latex doll just like me! We'll have so much fun together... fucking each other, fucking others... converting others... Doesn't it feel soooo good to be converted?"
The pink latex slime creeps down your hips, staining your penis a bright shade of magenta and shaping it into a smooth, long rubber dildo jutting out of your pelvis. You inadvertently utter a pleasured sigh as your narrow hips and thighs flare out into supple thickness, and your butt pops out into a bouncy bubble ass from underneath the rubber goo. The living doll's breasts drip onto your chest, and your nipples expand into A-cups, then C-cups, then DD-cups as your eyes roll back into your head and your mouth opens to release an orgasmic moan. The latex woman mounting you takes the opportunity to plant her soft lips onto yours and tangle her tongue with yours, leaving behind a slime that spread across your face and molds it into a similarly feminine form. As your hair is reshaped into one long wave of pink rubber, you look down at your fat, supple lips, your petite nose, and your smooth womanly face, and suddenly become struck with lust as your brain is converted to that of a sex doll. You reach your shapely arms around the sexy woman fucking you, and flip her over so that you're now on top again - only this time, both of you are horny latex pleasure dolls. You thrust your dildo-like penis into her as she shrieks in euphoria, and both of you almost instantly come, filling her with pink liquid latex. You pull your penis and it comes out of your new rubber vagina, having been converted into a large double dildo. You lean forward onto the rubber woman and envelop her in a hug as the two of you passionately make out. Between heavy breaths and giggling like a bimbo, you manage to exhale, "That was so much fun... we should share it with others!"
