Seeing as you had the day off to lay there in bed you decide to get back to fingering yourself cause your pleasure is not sated for long before you find yourself feeling horny again. As you finger yourself you feel the inside of your crotch starting to feel more and more sensitive as time goes on. You then take your fingers out letting your penis un invert and as you do you notice that your still flaccid penis is substantially smaller than it was earlier, confused you decide to go back to fingering yourself again but you suddenly realize that it's not enough to pleasure you anymore and you need something more.
Getting out of bed you know exactly what will help you relieve your sexual tension more and sneak down the hall to your mother's room as to not alert her. Once in her room you begin searching her room for what you know she has hiding in there somewhere until finally you find it. In a box under your mom's bed you find her vibrator, still clean from the last time she used it and you stuff the device in your pocket as you sneak back into your room. Once back in the privacy of your own room you waste no time pushing the device against the end of your penis until your penis inverts giving way for the vibrator to enter your crotch.
You are nervous at first but as soon as you switch the vibrator on all your nervousness washes away as pleasure overtakes it, It feels so good and enticing that you fail to notice your body changing more as time goes on. As the vibrator is whirring inside you in your pleasure filled mind you fail to notice as your hips widen ever so slightly until they are at a child bearing width. Your ass also enlarges becoming soft and plump to the touch, you then arch your back backwards as your stomach shrinks inward giving you an hourglass figure.
Your thighs then enlarge a bit to compensate for your larger hips and your calves shrink down to two dainty feet that shrink from their regular size 12 foot frame to a much smaller size 9 foot frame. As you lay there letting the vibrator continue it's assault on your penis you also start to feel your nipples get sensitive and as you lay there you place a hand on each nipple as you squeeze them and massage them your body erupts with even more pleasure as your shoulders narrow inward accentuating your lithe frame even more.
As you continue to massage your nipples you find your chest is growing as two breasts begin budding from your chest, as they do you find your slim and dainty hands taking these mounds into your palms as you continue to massage and squeeze them causing a cascade of pleasure to erupt throughout your entire body. As you lay there in the afterglow of your orgasm you again fail to notice your head take on a feminine form as your lips plump up into a pouty position and your eyes take on a more seductive look. You also don't notice your hair lengthening down your back stopping just above your ass.
You soon realize that the vibrator is losing it's effectiveness and as soon as you do you grab the end of it and plunge it even deeper into your crotch. As you do a verry feminine high pitched moan escapes your lips as a metamorphosis starts between your legs. First your inverted penis starts melding with the inside of your crotch becoming one and the skin on the outside of your penis shifts and becomes the inner walls of your crotch. the end of your penis shifts away from below the vibrator as it splits into two holes, one hole moves down closer to your anus taking the vibrator with it while the other hole remains in relatively the same spot.
Once the hole with your vibrator is in place it expands giving way to a much larger womb behind it, once this is done forming your balls then get sucked up into your crotch and they take their position as ovaries and transform into them. Finally the skin around the entrance to your new womb changes and forms lips making it clear to anyone that looked there that you were without a doubt a woman. As you lay there in the afterglow of your many orgasms and take the cum covered vibrator out of your vagina you fail to notice as all the body hair on your skin save for your head and pubic hair all evaporates leaving your skin smooth and bare to the touch.
You then fall asleep soon after having exhausted yourself too much, as you sleep you have a verry strange dream as you dream about two figures looking down at you smiling and you laying there wondering why they are smiling. Then your gaze shifts from looking at them to now looking down at your belly and your view is obstructed as you gaze at an enlarged belly that to you looks like a beer belly you've seen on older guys only much larger and completely hairless and smooth. Your dream self then places a hand on the belly and you could swear you feel slight movement underneath the skin as if something or someone were inside.
You then wake up in a sweat as the events from yesterday flood your mind again, panicked you then shoot up into a sitting position relieved to see no enlarged belly blocking your view but your heart immediately sinks as you see two mounds on your chest obstructing them instead and immediately realize that what happened yesterday was no dream.
