Are you still awake sweetie?

Oh sorry, I wanted to catch you before you'd gone to sleep. It's early for you to be drifting off, you must be feeling really tired right? You've been sleepy all day? Hmm, looks like we might have to have a little chat. Come on, sit up, move your pillo...you're topless? You've been hot all day too? (Sigh) Ok, we really need to talk.

Tomorrow is your 21st Birthday, we have so many plans for you. Your party for one is going to be amazing! There's just one small thing you need to know about. Erm, honey, you might be cursed! No please don't freak out, I said might. Erm...ok, let me tell you what happened and then we can go from there.

Do you remember that fortune teller who lived down the street? Yeah well, I went to see her a couple of times whilst I was trying to get pregnant. My friend at work suggested her and said she might be able to tell me what was going on. Oh honey, I was desperate. Your prick of a father was trying his best but no doctors could figure it out, so out of desperation, I turned to her.

She told me that there was a force stopping me from getting pregnant, something about an angry spirit in another life I can't remember. She told me she could make me a potion but needed to know a few things about me first. What I enjoyed doing, to which I said horse riding and what sex of a child did I want, I said a girl.

So she went into her back room and I could here her bashing and crashing around, until she came out with a bottle full of glowing red liquid. She told me to drink it before the glow faded. Now honey, normally I would've kindly declined and left but I was desperate, so I tried to down it but spit most of it out. Yeah , it had a strong weird taste.

She told me that would fix everything and I would fall pregnant the next time I had...er...well you know. Anyway, she then demanded £3000 in cash. I told her I didn't have that much money on me and she turned crazy! Shouting and screaming, I tried to calm her down but she wouldn't listen. I told her I would go and get the money and come back, but she didn't believe me and...well...put a curse on me. She said seeing as I enjoyed horses so much and acted like an ass, I would transform into one at random times. She then said that I would pass this on to my children should I dare have any. Safe to say I was freaked out, so left there quickly. I ran to the bank, got the money out and ran back to the house, but it was boarded up, it looked like it had been abondoned for years.

I went home and told your Dad and he just laughed and said she was crazy and probably just gave me mouthwash to drink or something. The bastard put my mind at ease far to easily and that night we...well you...made love. I'm sorry, but it's better than saying we had sex or worse yet fucked right? Haha, I'm sorry I'm sorry.

Anyways, 9 months later, you were born and he ran for the hills. Well this is the thing, I told you it was because he couldn't handle being a Dad...that wasn't entirely true. It was more that he couldn't handle what happened to me.

Ok, what I'm about to tell you is going to sound crazy, but I've had the feeling I get when the thing happens to me all day today and I felt the only way you'd believe me is if...well...you saw it for yourself. After you were born, I'd just fed you and put you to sleep in the cot.

All of a sudden I felt like I really needed to pee so ran to the toilet, once there I sat down and peed for what seemed like a minute. Now honey, I'm going to get a bit more detailed now and I need you to listen. I went to wipe down there and my (cough) vagina seemed bigger. Not only that but I wasn't just wiping pee, there was something thicker and stickier. I thought I might be something to do with after birth and decided I call the doctors. I pulled up my panties and went to the door where I caught myself in the mirror.

My breasts were bigger and swelling in my top and my hips seemed wider. Looking at my panties, I could see a stain in the crotch and thought I'd must of not wiped all the pee. Then...ok girl to girl chat here, remember how open we've been over the years with masturbation and pubic hair etc. Well I got really horny, my nipples went like bullets and my clitoris, well erected out of its hood and...began to grow. I noticed a light dusting of hair growing around my navel and upper thighs, then my soaking wet panties gave way and I could see everything. I was dripping girlcum...oh come on honey, we all make it, I've seen yours whilst...mmm...washing your panties...they smelled so...goood...what, no sorry ignore me, I erm got distracted.

Any way so yeah I had the urge to bend over whilst facing the mirror to see if there was and swelling and well there was...except it's was swelling that looked like a...well...a...a mare! But that wasn't just it, my clit had thickened and was growing out and down between my legs. I couldn't believe my eyes but I'd also grown...a horse cock! It would appear that although I didn't drink all of the potion, I swallowed enough to part transform me.

So, at that moment your Dad burst in, took one look at my equine bottom half, screamed like a girl and turned and ran away, never to be seen again. What happened next? Honey, are you squirming under the covers? (Gasp) look at your nipples! Someone's enjoying this story huh? You want me to continue? Ok, on one condition, pull down your covers, I want to see what's going on down there. Oh honey, your panties are soaked, oh no it's ok, please continue, masturbation is normal and your...pussy...smells so good...oh oh...ok, I'm gonna make this quick and I'm going to take...off my dressing gown...but keep my underwear on.

After your Dad ran out, I took my horsecock in my hand and (heavy breathing) started to...mmm...rub it...up and down...up...mmm...and down. Then I...oooh...plunged 3 fingers, mmm in to my sopping wet horse cunt! And...fuuucked myself....mmm...much like you are now...mmm...keep going...I think our transformations are synced....yes...yes...look at my panties...see the growing bulge...my darling girl, please can I masturbate with you? Mmm, thank you...yes yes...look at your panties...don't fight it...mmm, that's it, grow that horse cock, let it break free...mmm...like mines about to...fuuuuuck!

Oh baby, I can’t hold back anymore. Don’t touch your bulge, let it pulse bigger and bigger.thats it, mmm, look at how the material is stretching and all of your girl cum soaking through. Does it make you hard knowing your mommy has always been so impressed by how much cum you leave in your panties. How your mommy loved finding out you started having wet dreams by finding you sticky panties in the wash basket. Oh look at you moaning and whimpering, you do like hearing it don’t you? Fuck, look at your panties honey, they’ve started to tear and oh dear, your cum is now squirting out of you. Tut tut young lady, look at our your messy sheets.

Oh baby, you don’t need to beg me, you panties will give way shortly. In fact, I think I know what will do it. Do you know when you had the girls over for that slumber party? Do you know that after I’d said I was going to bed, I crept back to your room? And do you remember it was a full moon that night, coz I sure do. No no, you can’t cum yet. Well, I looked through the crack of your door and what do I see? 5 girls in their bras and panties masturbating together. Seeing how turned on you were told me your transformation wasn’t too far away. Mmm, and you know what happened next my darling girl? My clit began to grow and my pussy became soaking wet aaaaand, as my horse cock grew to full size, I grabbed it and stroked it hard with my left hand and I fingered my gaping pussy with my right. Hearing you all moan and smelling all of your sweet pussies just made me fuck myself harder and harder.

And then when you came and squirted in your panties and the other girls marvelled at you and you blushed as you slowly sucked your fingers dry. Oh yes my darling, look, your panties have torn off now. Mmm, look how your horse cock is drooling too, you’re making mommy so...horny...oooh.

Ok...now...the only way to transform back...is to cum out of your cock...you want it in your...oooh...face? Mmm, yeah, taste it, it tastes...aaah...amazing! That's it...keep stroking...keep strocking...fuck...I'm going to cum too....fuuuuuuuuck I'm cumming!!!

(Breathless) Oh honey, look at us, covered in our cum. Mmm, you liked that didn't you? So you're not mad? Oh thank you honey. Ok, just remember, if you feel hot and horny in the day, you will transform, that's all I know. Now get some sleep and we will get everything clean and ready for your slumber party tomorrow.
