"I'll use the dummy" Ben said. "If I am to do this I don't want to have to worry about not getting it in the cup you know" he quickly added as an excuse, but his friend knew him well enough that he was just too curious!
"Okay dummy it is, but before you do that, you should know I while we were talking, your ears have moved to the top of your head, and I think you are growing a mane" Liam said, pointing out some of his friends other changes.
Ben quickly felt his ears, they were now higher on his head, and covered in fur and than quickly felt his newly growing mane.
"This feels really weird, it does explain why I thought you were yelling though" Benjamin said.
Back to the task at hand, Benjamin turned towards the dummy.
"Okay, what do I have to do exactly?" He asked, as Liam walked around the dummy and gave his friend instructions.
"Well I just put the cup in, all you have to do, is put your dick inside this hole, and I think you'll know the rest yourself" Liam said.
Ben's horse cock, was now throbbing with excitement. He walked up to the dummy, and was preparing for the job at hand.
"Do you want some privacy, do you want me around? Just let me know" Liam asked his friend, not wanting to make him feel terrible.
"Well it would be helpful, if you were around, just in case" Ben said, not really knowing why he wanted an audience.
Ben lowered the dummy up to his height, took a breath and slid his equine member inside the dummy, feeling surprised with the cold feeling of the lubricant inside, and started thrusting back and forth.
The sensation was beyond description. With each thrust came a wave of pleasure that rushed through the boys body.
First feeling a bit unsure and with some awkward movements, his newly acquired horse instincts quickly jumped in to help him.
His tail swishing from side to side, Benjamin kept thrusting his horse cock inside the dummy.
With each thrust, the pleasure became more intense, as his equine penis came closer and closer to climaxing.
As he approached his final thrust, Benjamin started to whinny like a horse, not noticing that his legs were started to be covered in a dark brown fur.
His toenails darkened, and started to fuse together, his legs gave him new height, which was a bit uncomfortable seeing how he just lowered the mating dummy.
Huffing and puffing, Benjamin felt his horse cock tense up, and like an explosion of pleasure, a whole load of semen shot out from the tip of his penis.
"NEEEEIIIGHHH" Benjamin neighed as he finished his climax, a wave of pleasure shuddered through his entire body. He could get used to this!
Finally coming back to his senses, Benjamin noticed his new hooves and the fur covering his legs, as he pulled out from the mating dummy, his member quickly retracting back into its sheath.
"Nice job! Now I can simply get this cup out of the dummy and sell it without problem!" Liam said, trying not to be to awkward about the situation.
Benjamin carefully trotted towards the edge of his stall, where there was a small bench, and sat down.
Still panting from the exercise, he looked up at his friend. "Yeah no problem, that felt great!" He said with a glee smile.
Benjamin leant back into the bench and relaxed.
