>night falls on Fluttershy's cottage
>you snuggle with the heavily pregnant mare by the fireplace
>from time to time, you add a few logs to the fireplace
>no words break the silence, only cuddles
>your hand gently pets fluttershy's belly, mane and soft coat
>she smells so good.
>''thanks for taking care of me Anon... you're everything a mare could hope for''
''My privilege, Fluttershy''
>her belly jumps a little as the foal inside kick

>''Anon... wha... what's happening''
>she grunts and craddles her belly 
>if you look closely, the fur ripples and the big, fertile belly ripples
>itshappeningsobadly.jpg
>your penis has never hardenned this fast before.
>''Anon... there's so much pressure... Anon... what's going on?''
>you don't even listen to what fluttershy says, you just spring up and go fetch the rape...
>...I mean the rope in your bag.
>you had planned this for so long.
>fluttershy keeps squealing in fright, she knows what's going to happen to her body in the following hours, but she doesn't want to deny it
>''Anon... please... please help... it hurts so much...''
>fuck this
>you just remove your pants
>presenting your glorious erection to Fluttershy.
>''Anon... AH!... it's not... it's not the time for... for ah... for this!''

>you give a gentle push to Fluttershy, she's too weak to resist you
>she falls on her back, unable to get up because of her swollen belly
>you catch her pussy in all it's glory
>just in time too
>''Anon... Ah...AH!''
>she gives a yelp as her belly tightens and her water breaks, spraying her juices from her cunt all over the floor.
>''I'm scared Anon... what's happening?! Is my foal alright?''
>you keep silent as you tie her front legs together and hang them to the ceiling
>her meek, pathetic attempts to resist do nothing to stop you, she is too much in pain and swollen to move.
>''Gnah Anon it's moving inside! It hurts so much! P... please help me!''
>your dick has never throbbed this much in your whole life

>your dick is so hard it's likely starting to pierce the spacetime continuum
>fluttershy is crying, from the pain, the fear and from your betrayal
>she tought she could count on you in her moment of need
>this only makes this even hotter
>you can tell the foal has started sliding down her birth canal, she oppened her legs and she pushes along the contractions
>you have a perfect view of her wet, glorious, plump pregnant pussy, already stretching from the foal inside
>fluttershy cannot stop screaming
>''Anon! Why are you doing this?''
>fuck it, you're unable to resist, you start jacking off
>the foal's head crowns, stretching her vagina to the breaking point.
>her pussy is blood red and you hear it tears from where you stand, with fluttershy letting out a scream of pure pain along with it

''M... muh dick''
>you feel yourself closer over the edge
>but you should pace this out so you can cum at the most amazing time
>the foal's head is completely out already, stretching fluttershy's cunt
>her face is caked with tears, she panics wildly
>''Anon... help... help me''
>she is out of breath and can only begs you pathetically, in small whimpers
>you can see her belly being wrecked apart by contractions, she can barely push, only trying to ride the contraction as they pass
>the foal isn't moving of course, not until she can push it
>but she is too tired for that
>she can only lay on her back, crying and screaming, feeling the foal squirming inside of her, stretching her pussy wide like never before, desperate to be free from its mother's womb
>with the energy of despair, she gathers her strength for one last, desperate push
>''GNYAAAAAAAH!''
>her face reddens and scrunch and she lets a bloodcurling scream as she pushes as hard as she can
>Fluttershy's efforts are rewarded with her foal slowly sliding down out of her cunt and falling on the floor in a great gush of liquid

>it's a girl!
>the little one is a pegasus, with colouring very similar to her momma, 
>she is covered in vagoo, her umbilical cord snaking trough her mother's cunt, still connecting them both
>you hadn't fapped for weeks, waiting for the birth to finally blow your load on fluttershy
>you look her deeply in her eyes, even if she wasn't tied, she couldn't do anything, she was too tired
>her eyes are filled with tears
>this is so perfect
>you finally get over the edge and cum
>you've got enough semen to do this
>you fill her gaping, ravaged, cavernous pussy first, it's so sensitive from the birth that even your spurts of jizz likely cause her immense pain, then you cum onto her deflated belly, and the best for the last, you finish your load in her face and mane as she cries silently.
>you untie her, it's not like it makes a difference at this point, quiet sobbing fill the background
>fluttershy will never recover from this, that is certain
>as a crowning achievement for the best night oever, you place your mouth on her crotchtits, suckling fluttershy's milk for yourself

>you lap her milk with greed, it rightfully belongs to her baby, still screaming and wailing on the floor
>this is what makes this so good, it's a forbidden fruit
>fluttershy is so meek and helpless, too weak to stop you, too weak to pick up her foal and cradle it
>her birth, what should be the best moment in her life, ruined by her best friend, the one she trusted the most
>as you finish your meal, you wipe your mouth on her fur
>you're about to leave for the door, when you hear a quiet whimper
>''Anon... *sniff*... why did you do this?''
>you lean in closer to her ear and whisper
''It was my priviledge''
