"Thank you for taking care of me while Fluttershy's out, Anon."

"I just like to help out", you respond.

Rainbow Dash lay nestled on a nest of pillows she had built for herself. The fire could be heard softly crackling throughout the cottage. Sometimes Rainbow would ask you to add an extra log or two. Sometimes she'd ask you to take one out. The foal growing safely in her womb was taking her on a roller-coaster of want and craving.

"Do you need any more pillows?", you ask.

"No, this is fine. But could you... rub my belly maybe? My tummy is a little upset."

You sit on the edge of the nest as she rolls onto her back. You begin to gentle rub her fuzzy, swollen belly. She makes a sound you can only describe as purring and her hind hooves twitch occasionally. Nearly an hour passes, but your arm never seems to tire doing this.

Rainbow Dash becomes increasingly twitchy as you pet her. You don't pay much mind to it until her hoof touches your hand. You turn your head and catch her eyes. She stares straight into yours as her hoof guides your hand lower and lower.

"Rainbow Dash, I don't think-"

"Don't. Talk."

You obey and your hand eventually finds her warm marehood. She rolls onto her side and you lie down behind her, gently massaging her moist fur and she sighs and moans. She turns her head and you share a long kiss.

"An-an-ah! A-anon... I want you."

You nibble on her ear.

"Anon, I want you inside."

Not wanting to disobey a pregnant mare you hurriedly undo your belt.

"Don't stop~!"

You skillfully remove your pants single handed as Rainbow feebly tries to push her rump against your waist. She whimpers in anticipation as you slide your body close to hers. You slide your hand up to rub her plump belly and slide your throbbing manhood between her legs. She twists and thrusts, trying to take you into her. You slowly push against her, teasing her with your cock. You find the entrance to her love and push just your tip into her. She gasps and you feel her squirm, her body begging for the rest of you.

"Hold still", you whisper.

She quivers and whines as you slowly introduce the whole of yourself into her. She lets out a loud gasp as you push to the hilt. You move your hand in big circles over her stomach as you slowly withdraw, and thrust in again. Her wings push against your chest and the smell of her mane fills your nose. You kiss her neck as you both move in unison, time slipping away as you lose yourselves in passion.

"Anon, I'm going t-to... I'm gonna-"

You thrust faster. Rainbow's words fade to stutters, then groans. You feel her squeeze around you as she cries out in ecstasy. You thrust harder and harder, overcome by lust. Your lower half is soaked in juices. Her marehood squeezing you tighter and tighter as her moans become louder.

"Anon! I... I thin-ah! I think my water broke...", she says in a daze, "Anon, the baby's coming right now!"

"Me too, Dashie", you grunt.

You hug her tightly as you cum inside, but you're not finished. You roll her onto her back and examine her.

"Yeah... there's time", you mutter to yourself.

"Anon, what are you doing?", she asks in surprise, "What do I do?"

"Push, Dashie", you instruct, "Just look into my eyes and push."

You hold her hind legs as you run your re-hardened dick over her slick fur. Too tired, and too much in pain, Rainbow Dash obeys you without protest. Her exclamations become louder as the contractions worsen. Without warning you thrust into her and she screams in pain and pleasure.

"Anon, I can feel it. I can feel the baby coming!"

You don't mention it, but you can too. You can tell the unborn mare has a muzzle just like her mothers as the tip of your cock gently bumps against it. You can feel every contraction with Rainbow Dash. You watch as her tummy jiggles slightly with every thrust. You leg go of her legs and they wrap around your back. You hold her baby bump with both hands as you push into her. With a few more thrusts you're certain the unborn foal is unwittingly giving you a blowjob. Unable to control yourself any longer, you cum inside.

As you withdraw with one final contraction the newborn foal slides out along with you. Instinctively, Rainbow Dash leans forward and bites the umbilical chord in two. She likes the two of you clean as both mother and lover.

"Uhm... Anon?"

"Whuh?", you moan lazily.

"I think there's another one on the way."

A yelp accompanying another contraction confirms Rainbow's primal suspicion. Like magic (Maybe it WAS magic) your dick springs to life again. You place the newborn foal in the safety of her mother's wing and prepare your body for round two. It's going to be a long night, but you'll do anything for love.

Even that.
