Original Description:
 
Clopfic:  
AJ grunted as she crested the small hill. Despite her recent weight gain, she led the way, punctuated by frequent respites.
 
You spotted the log the same time she did. Jutting out over a small stream it afforded some partial shade from the woodland trees above: an ideal resting spot.
 
As she wordlessly eased her way over the river stones, you admire the calculated sashay of her tail and hips side-to-side, wisps of hair glazing her posterior. Her jeans remain perfectly taught as they had over the past hour under your watchful supervision as the caboose of your duo hiking party. Following a pair of ripped undergarments, she had began wearing her pants unzipped to relieve the tension, but this remained only a marginally effective solution and was far from the most notable change to her wardrobe.
 
AJ sighed contently as she rested her rump on the fallen timber, easing the load on her back and giving you a full view of her exposed chest, nipples standing erect in the cool calm breeze. Your foot makes a rapid plunge into the water below in response to your lapse in concentration. AJ looks up but you halt her offer for assistance with a gesture. You shake your leg dry and finish your river dance, bemoaning that your gait will be moist for the final leg of your journey.
 
The makeshift bench creaks but holds as you take your place beside your sweetheart. You briefly consider the notion of fainting exhaustion and leaning on her for support, with the less-than-subtle ulterior motive of hugging her engorged bosom. Her pregnancy had started gradually but accelerated rapidly these past few months, leaving her already prodigious chest absolutely swollen, ever taunting you to twist and tease her tantalizing teats. This expansion presented a challenge for the mare as she quickly outgrew her supply of tops. Expenses for larger clothing would strain the budget of the humble apple farmer seeking to save what she can for her new family. Where others would hobble together a make-shift solution or forego the public eye entirely, AJ readily embraced her body as a part of nature and adopted a topless demeanor in all her endeavors. This led to little complaint from you; prying eyes were rare on the ample apple acreage, and you quite enjoyed the added thrill of a casual run-in now being accentuated with your nose squished deeply into her exposed cleavage. You know there’s deeper motivation to the honest horse’s horny actions as every chore from cooking in the kitchen to hauling supplies inevitably turns into a tryst or literal roll in the hay.
 
AJ meets your gaze and smiles. You get lost in thought again staring into her sparkling emerald gems, only to snap back as you realize the rising blush in her cheeks was a mere distraction from the hand lifting your shirt and sneaking into your pants.
