You've been following her long enough and you can't stand to wait another minute. From your sitting position you grab her shoulders with your hooves and pull yourself up to kiss her. She's shocked, no reason why she wouldn't be, but you can't bring yourself to pull away even when she starts thumping her hooves against your shoulders. You try to force your tongue in, but she remains resistant and you can only get a slight taste for her mouth. Finally your need to breathe forces you back.
"Wh-why?" Derpy says as she pants for breath.
"I can't lie," You say, wiping your shared spittle from your mouth, "You're one of the sexiest mares I've ever met. That's why I followed you all this way."
"But, my eyes," She remarks, shamefully.
A coy smile dawns on your face, "I wasn't looking at your eyes. Not from behind at least."
"My.. Behind?" She blushes and smiles at once, "Naughty thing! You like this?"
She turns around, showing you that delicious bubble butt. She wiggles a little to the left, then to the right and she has you spellbound. You dive forward, always being the adventurous one, and dig your muzzle into her buttcrack.
"Whoah nelly! But, but it's all sweaty in there!"
You couldn't care less, you're too busy taking in her musty aroma. Maybe it's a trick of the mind, but between the thick aroma of her booty sweat you catch a hint of blueberry muffins. You dip your tongue in, just a little, and slurp up some of the salty concoction between her cheeks. It tastes as good as it smells, just a bit of sweet and plenty of salty.
"Ooah... Don't.. It's all dirty.." Derpy is still bashfully trying to discourage you from licking her ass. You plunge in further, placing your hooves on her hips to help you stay balanced while you eat her sweaty butt out. Your tongue starts diving further and further. You lick the left cheek and then the right, making sure you're covering every last inch in spittle. When you're satisfied with your lube job, you decide you need to work on the rims. Your tongue slaps up against her tailhole and starts making little circles about it.
"Eep! Cold!" Derpy cries out. She's never tried this before, that much is clear. You poke your tongue inside her lax pucker just once and that's all she needs. Derpy cries out and orgasms all over the shrub beside you.
"Oh, oh my muffins." That's all Derpy can manage to say.
"Enjoyed it?" You say playfully.
"Yeah.. A whole lot... Hey, did you maybe want..."
