Just then, he heard someone come in. Jesse Ronstead, the girl from the room next door. It occurred to Jake that she had borrowed his spare belt last week and had promised to return it.
He stood motionless as his nose caught an unfamiliar smell. Her scent, strong and overwhelming. His cock started to stiffen and grew out of its sheath, until it threatened to tear right through his pants. He reached for something to cover it, but then Jesse noticed.
She didn't say a word. Instead, she unzipped him and let his big horse cock flop free. It had grown to its full length, and now Jake could feel his balls beginning to tighten.
Jesse cupped his nuts with one hand and put her other on his shaft. Her hands were soft and warm, and Jake bit his lip hard. "Jake, you're...really big. And why are your legs so..."
She screamed upon realizing he had hooves and a tail.
That did it. A stream of cum came shooting out as Jake climaxed. His semen splashed all over Jesse's skirt and legs.
Jesse made a weird expression with her face. She started fidgeting with her shoes, like they were getting too small. By the time she got them off, two large tan hooves were ripping through the bottom of her pantyhose.
Then there was another ripping sound. A bushy tail poking through the back of her skirt. Thick fur was growing on her legs, stopping exactly at the waist. Jake was perplexed until he thought of something. Perhaps smelling Jesse, a female, had triggered some sort of mating instinct.
And just then, he felt his cock becoming stiffer and stiffer until it was hard as steel. Jesse smelled the pheromones being released into the air and grabbed the big thick dong.
"Judging from the size of those nuts, I'd say you have at least five gallons of sperm in there. Want me to drain all of it?" She batted her eyelashes and pursed her lips.
Jake didn't even realize the neigh coming out of his mouth.
