My sister Kerry was a spunky and sporty red-headed tomboy. She was mostly into stuff like snowboarding, mountain biking and rock climbing, so I was surprised when she took up equestrian which seemed like it would be far too boring and conservative for her.

Unfortunately I had promised her I would edit some videos from her showjumping practice sessions and competitions, and I can’t say my opinion about the sport had changed during this arduous work. Did she really have to get absolutely everything on film?

I clicked on the next video which had just as boring title as all of the others, and immediately did a spit take with the coke I was sipping, although I did wipe the stains off the screen just as quickly so I could see what was going on.

Kerry was kneeling on the floor of a horse stall with two of her best friends who had also joined the equestrian club along with her. Oh yeah, and all three of them were totally naked right now. I tried to limit my ogling to her friends, but I’d be lying if I said I succeeded at that. These three barely 18 college cuties made my pants feel very tight. Too bad one of them was my sister.

“Hi, I’m Kerry!” my sister said with a peppy voice and flashed a smile. Her very nubile and nude form was making my eyes melt even as I did my best to turn them away. Her equally cute friends also introduced themselves.

“And we’re Mindy…” said the brunette.

“And Tandy…” said the blonde.

“And this is The Horse Challenge!” Kerry winked and pointed at the camera, although I was staring at her perky nipples. I only noticed the big black stallion at the background when the girls started moving closer to it. They even had someone operating the camera because the zooms on the video were expertly done.

“This guy is called Dongle,” Kerry said, introducing the horse and its massive phallus which she lightly touched with her hand. “Can you guess where he gets his name?” She widened her eyes theatrically and covered her mouth with her hand like a coy 50s starlet. I have to say I was enjoying this production so far, especially since the other girls had moved towards the horse’s enormous testicles and started rubbing them with their hands. Tandy had pink nail polish and an amazing ass. Mindy had red nails and sweet hips, as the camera zoom was eager to show to us.

My sister’s hand was stroking the underside of the horse’s penis. Her body was thinner and more toned than the others’ because of her athletic exploits, and her breasts were smaller but perkier, especially the nipples which were constantly standing tall. The animal snorted and it started twitching. I was a bit worried at this point, to be honest. This looked dangerous. Then I realized this video must have been filmed a while ago and Kerry hadn’t been injured at any point, and that made me relax and enjoy the view.

When the horse’s member was fully erect and flared, Kerry positioned herself carefully so that her mouth covered the hole at its tip. Then she just suckled and stroked its underside with her gentle hands. The ball handlers were doing most of the work in the beginning. Kerry was just using her tongue a little and making sure her lips constantly stayed at the right spot even when the stallion’s enormous organ was throbbing and twitching.

The trio worked together, stroking and slurping until the horse started making loud whinnying sounds and finally they finally succeeded at what they were trying to do and got the stallion to deliver its immense load into my sister’s mouth with a loud gagging explosion which was well audible on the soundtrack. The entire length of the horse’s shaft had been throbbing and then it just suddenly went off like a pressure hose of gross gag-inducing slime and squirming equine spermatozoa, showing the true power which was needed to fertilize a mare. Judging by the sound she was making, my sister was having second thoughts about whether her tonsils needed to experience this fertilization, but that was unfortunately too late at this point…

This was Kerry’s star moment, and she pulled it off with great talent. When the horse came in my sister’s mouth she looked cuter than ever. Her huge doe-eyes were showed surprise and distress and her cheeks suddenly bulged to their limit and streams of thick, viscous, slimy and really disgusting looking goo shot from both corners of her mouth. It was immediately clear this was a lot more than what she had expected. Globs of white horse jizz dribbled down her nubile body and heavy, stringy, bouncy droplets hung off her perky nipples. I had to rewind the initial shot several times as well as carefully study my sister’s expressions in assorted pause images.

The horse kept snorting and whinnying and firing hard, and I was amazed to notice the motions in my sister’s throat. I realized she was struggling to swallow as much as possible despite the slimy coughing and gagging the horse’s immense ejaculations were causing, and she was trying to look cute on camera while doing it despite the obvious discomfort of the situation. She almost succeeded at it too, but I could see her eyes were wide and blinking. She was scared of the horse’s power which she was unable to fully cope with, and judging by the really nasty gagging sounds she was making she certainly wasn’t liking what she had to swallow. This was all about the dare and challenge of it and making a cool video for people to see.

The other girls seemed more into it at this point. Their hands were vigorously rubbing the stallion’s heavy testicles and they kept kissing and licking them while they were at it. Massive pulses continued jolting through the stallion’s shaft and spurting out of my heavily gagging sister’s mouth. Some of the ejaculations were so weighty I was scared she was going to choke and the fright in her own eyes was obvious as well.

The last five or so spurts were a bit weaker so she managed to swallow in their entirety, although they still made her cheeks bulge and it took several tries until they went down. Her expressions made it clear she wasn’t liking the taste and texture any better than before, but she was doing the best she could. Her lips stayed steadfastly latched on the hole until the horse finally started going limp. Even considering how much had spurted out of her mouth, she must have gotten a nice bellyful of slimy horse jizz and squirmy equine sperm cells, and she didn’t look all too happy about that.

Her friends certainly were impressed, though! They quickly cheered her up by patting her on the back so she could finish with a big disgusting gulp which made her wince but was important so that none of the horse’s think and sticky spunk would remain gargling in her throat. Then they took a quick group photo with my sister’s jizz-drenched body at the center and her friends sporting V-signs and their best smiles. They kissed her on the cheeks, and then the gooey driblets hanging from my sister’s perky nipples attracted the other girls who also wanted a taste of genuine horse semen, so they slid down and slurped them up and continued licking and suckling everything off her breasts. It tasted horrendous, of course, but it was an experience they could share with their grandchildren one day when they were of age. “You might not believe it, but grandma knows how horse’s sperm tastes like. That one evening at the stadium…”

Suddenly one cute friend kissed Kerry on the lips and then immediately blushed and apologized, having been caught in the heat of the moment. “Oh my God, sorry! I didn’t mean to do that! I just can’t believe you succeeded and… Mmp! Mmm…“

She seemed surprised when my sister kissed her back. Did I mention she’s also in the French club? I don’t know if they trained kissing there, but it sure seemed like it. The sticky horse goo was now all over the other girl’s sweet young body too, and soon my sister was on the ground and Mindy was straddling her face while Kerry caressed her cute ass.

The other friend Tandy was apparently less shy. She started tracing kisses downwards, slurping down the thickest globs of horse sperm on the way. She spent a while kissing my sister’s belly which was both covered in and full of warm horse semen. It was noticeably bulging despite Kerry’s toned abdominal muscles, so she must really have gotten her fill. I don’t even want to guess how gross it felt when a horse’s wiggly reproductive cells were swimming and sloshing around in your stomach. Tandy’s head started moving between my sister’s thighs, which like the girl’s face were dribbling with slimy horse sperm because a lot of it had initially ended up on her lap. These girls must have started feeling a bit hot while they were working on the horse and the stallion-sucking champion had now suddenly turned into an object of their desires. Luckily the camera was still rolling.

The girl on top raised her head and let out the most amazing orgasm whimper I have ever heard as her young body shook wildly and her fingers were clutching my sister’s hair. There must have been something very special about Kerry’s swift little tongue if she could make horses and girls come all the same. My sweet sister came at the same time, her thighs twitched hard and the girl between them blushed noticeably. Tandy’s fingers were working vigorously between her own legs after she had made them nice and slippery with a dollop of horse sperm. Her long hair had also become messy and sticky with it. They’d have a hell of a time washing that stuff off considering it was everywhere. I hoped they had nice showers at the horse stadium.

Three cute and naked teenage girls snuggling and cuddling in a huge pool of warm horse semen was a very appealing image to my eyes. The camera lingered on them for a while before the film ended with a credit roll where all the best moments were replayed inside a pink heart graphic, including slow motion shots of the weightiest spurts and zoom-ins to my sister’s throat as she struggled to make those big swallows. Closeups of her big scared eyes and bulging cheeks during the first ejaculation were also shown several times. That was the moment when she had realized just how much a horse would really shoot and how horrible it would taste from the beginning to the end. The last image shown was the one with the V-signs and smiles. So sweet.

I never actually mentioned to my sister that I had seen this video, and certainly not that I had copied it into my archives. I’m not sure if she ever realized it had been in the directory with the showjumping footage, but she always seemed to blush curiously whenever I mentioned something about horseplay… 2019
