[Not Gendered/Other] Obsessed with zebra's over-sized genitals and massive loads

This is a work of fiction. All characters are over the age of 18.

There's something I need to get off my chest and this is probably the only place I can share it.

I'm working on my zoology degree, so I was pretty excited when I got an internship at the city zoo. I won't say what city for obvious reasons, but it's a big deal.

After a couple weeks of prepping, feeding, cleaning, rinse, repeat, etc. it all felt pretty routine. I had no idea how much my mind was about to get blown.

About a week ago the zoo acquired a male Equus grevyi, aka Grevy's Zebra. He was a young, energetic stallion. For confidentiality's sake I'll call him Rocky.

After extensive examination, Rocky was finally cleared to interact with the other zebras. Everyone was excited, including myself, because there was a chance he would mate with one of the females. The Grevy's Zebra is the most threatened of the zebra species so this was a great opportunity to increase their population. I was also excited in a different way that I couldn't quite explain.

Introductions can be stressful and unpredictable, so observation was restricted to a limited number of zoo staff members. I begged my supervisor to come along. She liked my enthusiasm and hard work, so she agreed.

When they released Rocky from his pen, he did a few laps around the enclosure. He was magnificent; wild and powerful. I could have watched his muscular, striped body gallop around all day. I couldn't help but smile. Then he came to a halt and rolled onto his back. My jaw dropped.

Rocky's bulging black scrotum was shockingly large. Grevy's are known for having large genitals, but seeing this monsterous pair of balls in person was something else. As he writhed in the dirt, his grapefruit-sized sperm factories rolled around in their leathery black skin pouch. I had the weirdest urge to touch them.

The zookeeper led a breeding mare into the enclosure. She was in estrus and Rocky could smell it. He rolled over and stood up. He sniffed the air and I noticed a movement between his hind legs.

Rocky let down his penis. It extended further and further, past his hocks, almost to his hooves, until the flared tip of his pendulous cock hung mere inches from the ground and swayed gently. A strand of clear precum leaked out. I didn't know why, but my mouth started watering.

I thought about the summer before college. I helped my uncle make some youtube videos to promote his ranch. Mostly instructional stuff. The most memorable was the semen collection video. Uncle would let the stallions smell the females until they became aroused, but when a horse mounted, Uncle would grab the horse's thick penis and pull it out to the side so he could put the collection sleeve over it. A few thrusts and the stallion would ejaculate, filling the collection bag with hot seminal fluid. I must have watched that video a million times.

This was different, though. The beast was a beautiful wild Zebra and he was likely going to penetrate and ejaculate into a live female right in front of me. Rather than collection, I was about to see an actual live insemination. There were some other small differences, too.

Like I said, Grevy's zebras are known for their strikingly large genitalia. Rocky was no exception. His penis was larger than the one on my uncle's horse. Bigger in absolute terms, but also relative to the zebra's body size. It was almost absurd looking. The flare was bigger as well, expanding like a trumpet. Maybe more of a trombone given the size. A "tromboner," if you will (sorry, couldn't resist).

The virile zebra flexed his long black sex organ, making it swing upward and slap against his belly with an impressive "thwack." The clenching made it swell even more, thickening and stretching until the cleft tip reached between his front legs. He held it there and bucked his hips, rubbing the ridge of his throbbing glans against his chest. A bigger string of precum drooled out and swung beneath his flare.

"He's masturbating," the zookeeper called out. "Try to get him on the mare before he releases." Rocky relaxed and his penis swung down and bobbed beneath his torso, then he clenched and slapped it against his belly once more.

A handler gently guided the beautiful striped mare toward Rocky while another carefully urged the stallion toward her. The well-hung, fully aroused zebra stomped his foot, then stepped forward, preparing to mount the mare.

Unfortunately, when he reared up, his hefty member swung out to the side. Rather than burrowing into the female's womb, Rocky's penis ran alongside his striped flank, drooling tip rubbing against his shoulder.

"Get that penis it into her!" the zookeeper shouted.

I got ready to leap into the pen, but, thankfully, realized at the last second she wasn't talking to me. I wanted so badly to help, but it wasn't my job and would have got me in big trouble.

Rocky started humping. One of the handlers tried to hold the zebra steady while the other struggled to wrestle his powerful sex organ between his legs and guide it into the mare's vaginal opening.

I don't know why, but watching the handler squeeze Rocky's engorged black penis with both hands as he thrust wildly in her grip made me jealous. After a tense struggle, she got it back under him.

"We have penetration," she called out with a thumbs up. It was just in time.

In three strokes, Rocky began to ejaculate. An unbelievable volume of thick, white seminal fluid exploded out the sides of the zebra mare's vagina and audibly splattered on the ground.

The striped stallion continued to penetrate her, rhymically pumping more and more semen into her womb with enough overflow to create a waterfall of spunk that pooled into a great steaming puddle on the ground.

After a minute or so of wild, voluminous expulsion, Rocky hopped down, withdrawing his thick member from the female. It brought with it another giant glob of hot jizz.

Rocky was still erect and streaming cum. He flexed and the swollen flare of his cock once again swung up next to his shoulder and launched a jet of cum into the air beside him.

He twisted his head back and licked the wide, cleft tip of his own penis before the girthy black organ started to retract.

I stared in awe at the pond of zebra cum spreading across the ground. The average volume of a Grevy's zebra seminal emission is one liter which is impressive in and of itself, but this was much, much more than a liter.

"Do you think that's enough?" the zookeeper joked. Everyone laughed but me. I wasn't listening. I realized I had been touching myself and quickly stopped. I have no idea what came over me.

For the rest of the day, all I could think about was Rocky's massive black penis, his giant testicles, and the sea of cum they produced. Multiple co-workers asked if I was okay because I kept spacing out. I couldn't cut up the canteloupe for the monkeys because I kept cupping the melons and imagining they were the zebra stallion's balls. I over-watered several animals because the hose made me think of, well, you know.

My supervisor asked if I wanted to go home early and I told her yes, but I would come in extra early to make up for it.

When I got home, I ripped my clothes off and jumped into bed, and furiously masturbating. In less than a minute, I came harder than ever in my life, moaning so loud I think the neighbors heard.

I spent the rest of the night looking at pictures of zebras and playing with myself. None of them were as well-endowed as Rocky, but I still came at least half a dozen times that night.

The next day, I got to the zoo before dawn and went straight to the zebra pen. I was trembling with fear and excitement, unsure of exactly what I was about to do.

Rocky looked at me and the hide on his flanks rippled. We locked eyes. I felt a shiver run down my spine, but in a good way. My nipples hardened in my shirt and there was a tingling between my legs.

I saw something dark move in the corner of my eye, near Rocky's hindquarters. Just as I hoped, he was letting down his penis. I licked my lips and watched, mesmerized, as the thick, black organ with its bulbous tip once again descended between his legs until it almost touched the ground. I nearly came in my shorts at the sight of it.

I approached the big-dicked zebra carefully. I had no idea how he would react to me. I slowly reached my hand toward his face. He showed no fear. On the contrary, when I was close enough, he leaned forward and pressed his head into my hand. The movement made his dangling cock swing and made my mouth water.

As if he knew what I was there for, he flexed, straightening his penis and swinging it up to slap against his belly with a smack. I jumped a little and giggled. He did it again. I slid my hand up into my shirt and rubbed my nipples.

He flexed and slapped his cock a third time, but this time he held it there, pressed against his belly. I was impressed by the size. His penis ran the whole length of his belly, the flared tip all the way between his front legs, just touching his chest. I unbuttoned my shorts.

Rocky began to thrust, rubbing the top of his penis against his belly. I was rubbing myself as well. Then something magical happened.

Rocky relaxed and let his member swing backward, then twisted slightly and flexed again in such a way that his cock came out to the side, laying agains his flank. His giant cock head was pressed against his shoulder and pointed right me. He thrust again.

I was at the brink of orgasm. I bit my hand hard to avoid crying out and the pain kept me from cumming. Then he twisted his head back and licked the tip of his penis again.

I started shaking and fell forward. Rocky leaned toward me, pressing his muscular, striped body against me so I didn't collapse.

In doing so, he sandwiched the broad flare of his cock between my chest and his shoulder. It felt massive, soft and yet firm. He huffed and I felt it swell and harden between us.

Rocky grunted and thrust his hips, slowly fucking the tight gap between our bodies. Still pressing hard against him, I slid my body toward his hindquarters until I could reach out and finally hold his massive balls in my hand.

They were even heavier than I imagined, and hotter. I gently cupped and squeezed them with one hand. Sliding down his flank had exposed the flaring trumpet of a cock head. I grabbed it with my other hand and squeezed.

So there I was, arms spread wide, leaning against this beautiful zebra, one hand fondling his gargantuan testes, the other squeezing his wide, pulsating cockhead as he grunted and thrust his hips, fucking our compressed bodies. I started to cum. So did the zebra.

Rocky thrust forward hard and stayed there, braying. A thick blast of white spunk sprayed from his swollen penis followed by several more jets of ropey zebra cum.

I could feel each volley of semen travel the length of his thick shaft before blasting out the tip. The force of his ejaculation carried each volley of potent seed across the pen, splattering on the wall and dripping down. My hips bucked hard in an involuntary, hands-free orgasm.

I heard my boss's car pull up. I snuck out the back, cleaned up, and came in the front, pretending I had just arrived. She seemed a little suspicious, but was too busy to for her to investigate.

I want to visit Rocky again so bad, maybe go further with him than last time, but I'm too afraid of being caught.

He masturbates a lot, squishing his penis between his flank and the wall of the enclosure then thrusting like he did with my body. His loads aren't as big when he does it himself, but they're still pretty impressive. I recorded a video of it when no one was around. I watch that video a lot.

Anyway, I hope you don't think badly of me. I couldn't help it. Rocky seemed to enjoy it as well. Thanks for letting me get this off my chest.
