Five hundred meters away from the Tower of the Sorceress
"Hurry up, now, I don't pay you to be slacking off." The young wizard Kyras urged his familiar on, and she grunted in response.
"Yes, Master, coming...Master..." Shiki panted. You don't pay me at all! She fumed internally, the devious oni having long learned to hide her displeasure from her Master. Even when he was being so unreasonable as to have her carry a massive backpack on her tiny body just so he could see her out of breath and have reason to punish her later. It was so unfair! Her body--three feet tall, each breast bigger than her own head, and a womb that could take an ogre--was not built for heavy manual labor, even if she was an oni!
It was his fault her body looked like this in the first place too. Among the demonic Oni, the ones with the most magical affinity were the Shikigami. They made powerful familiars, growing in power along with their master in a symbiotic relationship. The only problem was that their form was influenced by the mind of their summoner, and Kyras's mind was more twisted and perverted than anyone's.
"Get the lead out. I can see the tower. We're almost there." The young wizard scolded. He was young, impatient, rude, sadistic, and completely lacking in empathy. If not for his incredible talent with magic, she'd have tried to wiggle out of the contract they'd signed long ago. It certainly wasn't his looks. He dressed in simple wizard robes, grew his naturally red hair out so long it got in his eyes, and his physique could be described as scrawny at best.
Well, aside from the monster he had between his legs...
In any case, if he wanted her to hurry, he could have put their supplies in his Bag of Holding! Or even better, not fucked her so hard her legs still felt like noodles! She clenched her teeth and tried to speed up, but only ended up tripping and falling, her massive breasts breaking her fall. Unfortunately for her, he'd not only made them massive, but horribly sensitive as well, "Ow ow ow!" She cried out as she flailed, sandwiched in-between the road and the heavy backpack.
