Coming up with names will probably remain my biggest struggle when it comes to making captions. Especially when the damn character limit then messes up whatever name I finally came up with.
Oh well, this is my first inanimate TF. I usually don't like inanimate TFs, but sex toys and especially onaholes and sex dolls are pretty cool, so I might rarely write something containing them.

"... Could this be it?.."
After many dead ends, fake websites and deleted websites, Tim managed to find a small forum called "Sorsera". He clicked a pinned thread titled "getting started".
Quickly skimming through it, it seems to mostly be safety advice on the usage of magic, and some basic information on how to actually use it. Cautiously optimistic, he slowly begins to smile.
"It does look promising... Hmm.. let's get something interesting right away." *Sigh* "I definitely need that after all the disappointments..."
On the lower right side of the page, he sees a list of recent hot threads. Among them, a thread titled "spell that makes sex very easy and pleasurable" catches his eye.
Blushing slightly, he thinks about it for a moment, before eventually deciding to start reading it.

The thread started with a long post, and seemed to have a lot of comments, the top of which reading: "Lol, careful guys, this would actually work"
That was enough for him. Though he didn't understand exactly what it did or how, but it was a full set of instructions to cast some kind of sex spell, and he was going to give it a try.

As he began following the steps, he quickly managed to create a little blue glowing orb of magical energy in his palm.
He could barely contain himself at the confirmation that the site did have accurate information on practical thaumatology.
Excitedly, he removed his clothes as he quickly continued following the steps, without really focusing on the question of how the spell would work. Eventually the orb tripled in size and he got to the final step.

Tim grabbed the orb, causing its energy to quickly be absorbed into his hand. He could almost immediately tell that something was wrong, as his hand started to turn blue and translucent.
"Huh? I-is it supposed to do that?" He quickly scrolled down to check the comments, and to his horror most of them just seemed to be laughing, except for one.
"What moron would actually turn themselves into an onahole XD... Well... I guess there are probly a few people who would out there ಠ__ಠ"
By the time he finished reading the comment the transformation had already spread up to his shoulder. His arm looked girly and felt stiff to the point where he could barely move it.
He wanted to further look through the thread to find a way to stop and reverse the transformation, but it was already too late.

The change suddenly spread through his whole torso, beginning to creep up his neck and into his other arm and limbs.
A large pair of boobs suddenly exploded out from his chest as his translucent torso took on a womanly shape. They bounced softly, and seemed much more supple than what most of his body was turning into.
As the changes continued, his limbs and his dick quickly began to retract, causing him to stumble and fall.
"Ow, fuck!" His masculine voice sounded strange coming from his feminine body, but it wouldn't matter for much longer.
While his limbs fully disappeared, his sex suddenly inverted, becoming a large hole with a ribbed interior. It combined with her ass, and extended up through her torso, causing her to let out a final surprised gasp.
The transformation finally engulfed her head, causing her face to turn feminine and forcing her mouth open as it connected to her pussy cavity.
Her hair turned blue and translucent as well, fusing into a few large soft hairlike masses which reached down to her butt. She then rapidly began to shrink, causing her body’s sensitivity to increase tenfold.
Once her body reached a dolllike size, the transformation finally came to an end.

Her body felt incredibly stiff to her, though someone else would probably be able to bend and stretch her easily. She tried to move around, but even just squirming slightly proved to be near impossible.
She slowly managed to look down at her breasts, and around the room. But even if there was anything that could help the poor sex toy, she would be completely unable to reach it in any way.
So for hours she just laid there helplessly, until she heard the door open, and her roommate stepped in.
At first, she was relieved. When she thought more about her roommate and her situation though, she realised that him finding her would not be a good thing. He already had a small collection of onaholes after all.
