The moment you saw it, you knew this had to become your dick. “I want this one!” Flared head, mottled colors, impressive girth, massive balls and definitely bigger than even Eboni’s dick. What you saw was a prime specimen of an equine penis.
“Wow, you’re definitely not half-assing things,” Eboni commented, her bulge didn't hide her true thoughts very well. “The horse dong is quite the beast. Even I tagged out at the last moment.”
“Just so you know, Ruby, if you choose an inhuman dick, your body will take on some of its characteristics. In this case you’re guaranteed to take on some horse features. How many changes you will get depends on you and how far you want to go, but it's almost impossible to go completely without any. Are you OK with that?”
Somehow all their warnings only helped you in affirming your choice. “Yes, I want this one as my dick.” You carefully lifted the massive 24 inch dildo out of its box, lowered your skirt and held the aforementioned penis over your already excited vagina.
The moment you let go it fell down, actually crushing a box.
Unlike Natalie, Eboni managed to mostly hold back her laugh. “You were going a bit fast. Fitting for a future horse. Come. In our club room we’ll show you how to do it properly.”
You dressed up again and the two futas quickly led you to the Futanari Club room. The room was pretty large with a plain square table in the middle for normal club meetings and discussions. A large kings-sized bed, its purpose fairly obvious, was taking all the attention away from the table though. On one wall hung a large flat screen TV and the opposite wall held many shelves filled with magazines, books, games and more of mostly futa porn. In one corner were also a full body mirror and a sewing machine, which Natalie explained was for fixing the rips and tears their clothes tended to gather as it was much cheaper than always buying new ones.
“You were already on the right track,” Eboni said. “But just placing it there isn't enough. So hold your horses and make yourself comfortable first.”
After completely undressing you sat down on the bed and held the horse penis against your crotch with nothing happening again.
“Alright, keep holding it there and start slowly stroking, as if it is a part of your body already,” Natalie explained. “And pace yourself properly, this is not a race. You are going to go through some equine changes, so don't be surprised. You should still be able to be mostly human afterwards, don't run off.”
You nodded and began to rub the horse dick just as instructed, needing two hands to even hold it. By the time you got started properly, both Natalie and Eboni had taken off their skirts and panties. The two laid down in an obvious 69-position and began to suck the other’s dick, while using their fingers to stimulate the respective other two holes.
You continued to stroke, as you watched Natalie and Eboni having sex. Suddenly new and foreign sensations could be felt by you. It was still very faint, but you were certain you could feel the horse dick being touched by your hand, meaning the merging had already begun. Excited, you increased the pace of your own movements.
While it had already looked pretty realistic, you could swear that thepenis looked even more real with every moment. As connections were formed to your body, the sensations from it increased. Your whole skin was itching, as a thin coat of brown fur spread over your body. Your toes hardened, while both of your feet compressed and became hooves.
You fervently kept stroking the dick that became more and more fused to you and in turn more and more sensitive. Meanwhile the changes reached your head. Your face slightly pushed forward into a facsimile of an equine snout. Your ears traveled upward as they turned into long equine ears that poke out of your hair. Finally you could feel something pushing out of your tailbone, but you were too distracted to check now. What it was should've been pretty obvious anyways.
Eboni and Natalie meanwhile had reached their high point. Both were clearly solely focused on deepthroating the other's cock. Almost simultaneously both began to grunt around the dicks in their mouths. On their throats you could clearly see them swallow as much cum as possible.
Shortly after you reached your own orgasm and with it your transformation finished. As you watched the cum shoot out of your horse dick and almost reach the ceiling of the room, you knew that you had made the right decision.
After a moment of rest Natalie came over and helped you up. Not that you felt it necessary, you felt quite energized again already. Must be the stamina of a horse. You were led to the mirror to check out your new body. You looked like an anthropomorphic horse from a cartoon. Your whole body was covered in a coat of reddish brown fur, aside from white fetlocks around your hooves, white fur covering your stomach, starting halfway over your breasts, and the now white freckles on your short snout. Your horsetail was in the same red as the hair on your head. Your new futa dick looked like you had been born with it and was long enough to rest between your breasts when upright.
Eboni picked up your skirt. “I’m gonna add a hole for your tail. Don't think I can help with your shoes though. Do you want a hat to hide your horse ears?”
“Nah, don't bother. I’m proud of this body and I want everyone to see this. I’m looking gorgeous.”
“And very breedable,” Natalie threw in. “How about another round?”
