You stare at the mirror in disbelief. All you see in front of you is a feminine crotch.
You hesitantly reach down, seeing your hands from below. You touch your face, and at the exact same time you see you hand's reflection touch the pussy in the mirror. It feels weird. It's like the labia majora are also your lips. They're incredibly sensitive. You resist touching them more for now.
You decide to try and ignore yourself for a bit to see if you can get some answers. Walking back downstairs, you grab the card you had before. Now, the note on the back is different. It reads "Just so you know, you'll be like that until tomorrow. You'll love being between your legs until then though. Have fun down there!"
Reading the note over a few more times, you still can't believe this is happening. At least you still have the rest of your body (minus your head of course). Speaking of, you wonder if your new body has boobs or not. Your hands quickly shoot up to your chest by feel. Sure enough, you grasp two decently-sized, naked breasts. They feel weird, but you like them, even if you can't see them.
Heading back to your room, you walk up to the mirror, watching your crotch get closer in the reflection until it fills your vision. You're slowly starting to feel better about this situation. Maybe you're even enjoying yourself a little bit. You slide your hands down your naked body, seeing them arrive at your crotch. They find themselves on your 'face', drawing a heart around your smooth pussy lips. You're quickly getting turned on.
You touch one finger to your lips, feeling them buzz with pleasure as you move it up and down. Your lips begin to feel wet. You slowly push a finger in, feeling your wet, squishy insides. It feels amazing. Focusing on the mirror for a moment, you see your hand covering your crotch with the middle finger bent down. You reach up with your other hand to one of your nipples. You fiddle with it while you slip another finger into your 'mouth', sliding past your moist lips.
This continues for a good 3 minutes, rubbing your breasts and your crotch. You are completely lost in the pleasure and the view in the mirror. This feels amazing. Then you reach your climax. You arch your pelvis (and, in turn, your face) forward, spraying your juices from your lips in a messy show of pleasure, splatting against the mirror and your hand.
You slow down your movements as you come back down from your ecstatic high, eventually stopping and bringing your arms to your sides. You grab some tissues and wipe yourself and the mirror down, thinking about what the hell just happened. You still feel weird, but you kind of like it.
You could get used to this.
