Two students were trotting down the hallways of Manehattan University. With their latest class having ended less than a minute ago, they had more than half an hour until either one of them had to go to their next lecture. Quiet Midnight, a bat pony stallion, attempted to strike up a conversation with his friend, Cloud Cuddler, a pegasus mare, shortly after the duo had left the classroom.
"I'm excited that buckball season is around the corner, did you know Manehattan's introducing their first ever bat pony to play defense on their team?" The stallion inquired to his colleague with a warm smile.
"Yeah, I heard," was all the mare managed to conjure up as a reply. Stowing her water bottle in her saddle bags, she had her mind focused on another topic. She had drunk a significant amount of liquid throughout their class, which wasn't out of the common for students, and evidently it was starting to work its way through her system. She kept her hind legs close together while she walked to reduce her bodily discomfort.
A moment after her response, she noticed a sign down the hall representing one of the school's unisex restrooms. "Hey, Midnight," she stuttered out, "Would you mind if we stopped at the bathroom really quick?"
"Sure thing," the bat pony replied before the duo trotted in.
Cloud Cuddler stepped into the tile-floored room and, with her hind legs shaking in anticipation, quickly dashed into one of the stalls. As she did so, Midnight stood in front of the mirror and pulled out a comb from his shirt pocket. He ran the hair styling tool through his mane as he admired his masculine muzzle structure, wanting to make sure he looks good for his next lecture. He heard the rushing of hoof steps to his right, no doubt from Cloud. Not batting much of an eye at the noise he kept up his act of personal grooming when a different, more startling sound arose.
"Dear, Celestia! Are you kidding me!"
The shout from his friend caused him to jump and drop his comb. Turning his attention to his colleague's distress, he trotted from around the corner to see Cloud slightly bent over with her hind legs shaking intensely as she groaned out her discontent, "Cloud, what happened?" Inquired the stallion.
Cloud looked up with a grimace, "The toilets in both stalls are out of order! I need to pee right now! And I don't want to leave a puddle for the janitors to clean up!" She blurted out as she clenched her urethral muscles as tightly as she could, her penis hung limply out of her sheath as she felt moments away from releasing a yellow monsoon.
Midnight was completely caught off guard, he hadn't prepared for incredibly situational scenarios like this. He wanted to help his friend but was left clueless as to what he should do. His mind raced to find a viable solution to offer. Pee in the trash can? No, that would probably be worse. Pee in the sink? Again, worse. Hold it in and rush to a different restroom? That would be a good idea, if her body language didn’t make it obvious that it wasn't an achievable result by any stretch of imagination.
With the speed of his pondering comparable to that of a Wonderbolt in flight, an idea for a possible urine receptacle popped into his head. Quickly thinking through the pros and cons, he decided it was the most effective option. Laying himself down on the floor, he hastily got into as comfortable a position as time would allow. With his flank facing Cloud, he raised his left hind leg into the air, "Here, Cloud, use me!"
With the urgency in her friend's voice and the odd context of what he suggested, she looked up to be greeted with the sight of Midnight's cunt on full display in front of her. The view of his vulva momentarily moved her focus away from the discomfort of her bladder. She stared at the folds of his pink labia as the patterns subconsciously enticed her. With Cloud’s eyes constantly taking in the picture of his stallionhood, lustful thoughts rushed through her mind, causing her marehood to harden from the blood rushing to it. "What, but I," was all she got out of her mouth before Midnight interrupted.
"Don't argue! Stick that gorgeous marehood in!" He further encouraged, hoping that his compliment would solidify the clarity of his insistence.
Whether Midnight’s idea was good or not was undecided as there was no time to judge it. Cloud Cuddler immediately jumped at the opportunity in front of her and dashed over to her friend. With her body shaking from the sudden influx of strong emotions and physical discomfort, she pressed her chest against Midnight’s back as she positioned her hips accordingly.
As her penis finished stiffening up at the thought of inserting it in a stallion’s vagina, the thought came true. She gently slipped her marehood into the warmth of Midnight’s pussy. She made a soft, feminine moan as she felt the sparks of pleasure jolt throughout her body from her cock sinking into the vaginal depths. Midnight was no stranger to having mare parts inserted into his stallionhood, nevertheless, it still excited him each time and now was no exception. He let out a masculine grunt as he felt his friend’s phallus spread the insides of his birth canal wide open.
The mare’s member eventually became fully engulfed in the vagina, penetrating Midnight’s cervix slightly as she was now perfectly in the position to safely contain the urine she wished to release. She panted slightly as she anticipated the relief of having her bladder fully drained, she could feel the golden liquid flowing through her urinary tract. With a quick inhale she braced herself for the strong sensations that were to come, and then she let it all out.
A stream of piss started flowing out of the tip of her penis and directly into the container that was Quiet Midnight’s uterus. She let out a loud moan of relief as she felt the hot urine finally seize to stretch her bladder. The stallion chuckled lightly as he heard the pegasus mare’s clear signal of gratification. Cloud relaxed her body against the warmth of the bat pony’s as she fully immersed herself in the satisfaction of getting to urinate without making a mess on the floor, or at least, not a giant one, as some of her pee leaked out from the stallion’s vaginal tunnel and trickled onto the floor. Fortunately, most was going straight into his womb as planned.
Midnight’s eyes drifted downward to soak in the sight of his friend’s cock inserted into his pussy, something about the sight and feeling of having his vagina used as what could be described as an organic toilet sent shivers throughout his body, his leather wings tingling at the thought. He felt a sense of fulfillment as his womb was gradually filled up like a water balloon. The hot touch of mare piss washing against his epithelial cells brought a sense of snugness to both his male sex organs and his mind before he went back to looking at his friend’s emotional contentment plastered on her equine face.
Cloud leaned further into the comfort of Midnight’s body as she opened one of her eyes to see the bat pony’s mouth curled into a smile, queuing her in on how glad he was to help. With the golden fluids still steadily filling up the stallion’s foal-growing organ and her tongue hanging out of her mouth as she panted, she decided to express her gratitude, “Thanks, Midnight, I really had to go.”
The bat stallion chuckled, “Of course, Cloud, what are friends for?” He rationalized as the mare’s bodily tension dissipated further. He almost felt like he should be thanking her too.
With the mare’s stream of urine reaching its end, Cloud moaned deeply as she had achieved her desired relief, in one of the most wonderful ways she could have imagined. Her bladder was finally empty as she wanted, though the same couldn’t be said for Midnight’s womb.
As the two ponies panted, one more heavily than the other, they heard a hoof step and looked up to see a janitor mare staring at the couple in coitus, “Uhm, don’t you two have water bottles?”
