A Quick Run With Sally

"I was thinking we could go for a ride out back," she says. "I just got a new course set up; you should totally come practice with me!"

Riding your girlfriend? What a strange concept, especially considering it won't be sexual. You'd like to avoid most things sexual between the two of you as much as possible; your mom was right to warn you, that dick she has really could kill you! But just going for a ride around an obstacle course doesn't sound too bad; who knows, it could even be kinda fun.

"Uhm, sure," you say after a bit of consideration.

"Awesome! I'll grab my saddle and we'll head out!" Her hooves clop along the wooden floor as she heads toward the back of the house. As you follow her, you notice a lot of the house has been enlarged to accommodate her; hallways are wider, rooms are bigger to allow more space between the furniture, ceilings are higher; it must've cost her family a fortune and a half to get this whole house redone when the found out Sally was half horse. But you know them, money has never been an object when it comes to their daughter.

You look at the photos put up along the walls in the main hallway. Each and every one that used to feature human Sally involves centaur Sally now; all the way from a little foal in kindergarten all the way to a stallion in highschool. Interspersed are pictures of her holding trophies or blue ribbons at horse shows and other such competitions; looks like she even turned being a halfbreed freak into success. Seems that her mom is the one who rides her at competitions; at least that sounds better than her dad riding her. You just find it odd that her parents were comfortable with their daughter's massive dick hanging down in full view in practically all of these photos, but maybe since that part of her is a horse it's more acceptable?

As you're observing her family photos, Sally digs through the hall closet and grabs a big brown leather saddle, and sets it on her lower back before grabbing her phone and a huge pitcher from the fridge, and continuing to the sliding glass door leading to the back yard. You decide to follow her from the side at minimum from now on. Her back patio has a huge inground pool with crystal clear blue water surrounded by lounge chairs, as a patio furniture set where she sets down the huge pitcher. The yard itself is huge, much bigger than you remember it to be, and plenty of room for a horse to run around in. It's quite warm out, and the delightful sounds of a regular summer neighborhood play through the air on this very irregular summer day.

"Let me just get this stuff off," Sally says, drawing your attention. "Eww, don't look," she giggles, not being totally serious as she reaches for her skirt. She pushes it down and lets it fall to the stone patio (it barely covered what it needed to to begin with). She surprises you, however, when she reaches for her blouse, lifting it over her head and placing it on the table. She then proceeds to remove her bra as well, revealing her perfect C-cup tits; now this is part of her you could look at all day long.

"Don't stare," she teases, playing coy and pretending to cover her chest. "Haven't I told you before? I work out naked. Clothes just make me feel so restricted; besides, who'd wanna get all sweaty in then anyway?"

"I'm fine with that," you tell her, grinning. Besides, her back yard is surrounded with tall white privacy fencing, so nobody would see anyway.

"There's just one thing: could you help me with my horseshoes?" she asks. You're hesitant, and tell her you're not familiar with the process. "Oh it's so easy! You just nail them to my hooves." You look at her in disbelief at the idea of nailing something to her foot. "Oh relax, it's like a big toenail; I won't even feel it!" She grabs four metal horseshoes off a small rack on the side of the house, plus some nails and a hammer, and hands them to you.

You sit down next to her as she bends back her right foreleg, presenting it to be shoed. You line the metal object up with the hoof and follow her instructions, successfully nailing it in place. Again, it worries you to be driving a nail into a living being, but if she says it's okay, you believe her. Being down below her certainly puts things in perspective, though; you thought her horse body was big before, but from here it's massive, almost intimidating.

As you shoe her back legs, you're **** to look at something else intimidating as well: her gargantuan cock. It hangs right in front of your face the whole time you're down there, an incredibly large piece of meat even for a horse! You try your best not to look at it, but... it's right there! It's thicker than your own head, and seeing it so close up keeps reminding you of that picture on your phone. You have to **** back the bile that comes to the back of your throat at the thought of it.

You're also quite aware of her massive testicles dangling above your head, mostly due to the amount of heat and the pungent musk they put out. It smells extremely manly and animalistic; you hate it, but it's one of those smells you just keep smelling...

"Enjoying the view down there?" Sally asks, looking back at you with a grin. "I know how much you just love being under me."

"Ye-- uhh, no-- uhh," you stutter, unsure what would be the correct answer. Apparently she has a memory of you loving her big disgusting horse cock, but do you lie to her and say you like it? Or tell the truth and possibly upset her? Most of her body is sorta, like, a huge, potentially dangerous animal now; getting her upset with you is probably the last thing you wanna do. "I love it," you resolve to say through gritted teeth.

"Hehe, I knew it. And just think, you've got all weekend to play with it..." As she says this, you can see her rod beginning to swell up. Good lord, it gets bigger. She gets up to half mast, which has to be nearly five feet, maybe longer. And again, this isn't even full size. You just try to ignore her inflating rod and just finish the job you're down here for.

All shoed up, Sally pats the leather seat on her back. "Saddle up, cowboy," she says, giggling. She gives you a hand as you step into the stirrups. "Hmmm, you're heavier than my mom, but I could use the workout." She then picks up her iPhone (with a horse themed case, of course) and opens up the stopwatch app. "Could you time me? I wanna get a good base time." You take her phone and get ready to hit the start button. Finding nothing to hold onto, you wrap your arms around her human waist.

As Sally stretches her legs, you think to yourself what a strange feeling this is, to think you're sitting on your girlfriend's back right now. It kinda hurts your head thinking about it; that this smooth, narrow waist you're holding onto belongs to a horse, and that this fine bristle like hair against your legs belongs to your girlfriend. You also become quite aware of how high up you are; her horse body itself is just a little taller than you, you're sitting almost 6 feet off the ground (however many hands that is).

With Sally all prepared, you hold on tight and prepare the countdown. "On your mark! Get set! Go!" As soon as you say "go", you almost loose your grip on her; she takes off like a rocket, galloping to the first jump at breakneck speed. The peaceful sounds of the calm summer morning are drowned out by the thunderous sound of her hooves as she sprints across the yard. She clears the small jump with barely any effort, continuing to the next. She said she wasn't used to your weight, but she moves as if you're not even on her! She flies around the course, clearing huge jumps as if they're nothing, and making corners with perfect precision. This horse body of hers is incredibly strong.

"Aaaaand time!" she says, slowing to a trot. You stop the timer and read out her time.

"One minute, forty two seconds," you tell her.

"Hmmm, it's not bad, but not great. I know I can do better. Let's go again!" After all that exertion you're surprised she's so eager for a second lap, but from the looks of her she's barely broken a sweat, even in this heat! You reset the timer and ready yourself for round two.

"Ready! Set! Go!" Again, Sally blazes around the track, somehow pushing herself even harder than last time. She cuts turns tighter, recovers from bigger jumps faster, and in the end comes out with a time eight seconds faster than the last.

"Whew. Getting there," she says, now noticeably starting to sweat. "I wanna try for a minute twenty-five." She is one dedicated girl! You join her for four more laps around the course, but by the time she calls it quits, she's still five seconds off her target time.

"Ah, I'll try again tomorrow," she says, breathing heavily, sweat pouring down her skin, and yours as well. Even just riding on her back you've still been in the heat, and her body that you've held onto all this time has been putting out a lot of heat as well. She walks over to the table and grabs the pitcher of water she brought out, lifting it up to her face and taking huge, messy swigs from it, not even caring that ice water is pouring down her bare chest and getting her nipples rock hard; it probably feels good in the heat. She eventually turns around and hands the pitcher to you. The ice cold water is very refreshing in the heat, but you want to save most of it for your girlfriend since she was the one exerting herself.

"So, what did you think?" Sally asks as you dismount her.

"That was... honestly incredible," you tell her truthfully. "I had no idea you could move so fast."

"I mean, you've been to my competitions before, so you must've seen..."

"I mean uhh, it's not the same watching as compared to riding, ya know? Whole different feeling." You want to keep this facade up for a while. Even if it means telling some little white lies.

"Oh, I guess I see what you mean. Now, why don't..."
