Admiring himself in his mirror, Ruben was quite pleased. He forgot all about to fright of turning into a child, as he has now regained his age.
Rubbing his diaper, he trotted towards the yard.
It was a long way before he would see anyone, as his house was a little bit remote, so Ruben could walk around without worrying about being noticed.
Eager to put his hooves on the grass, Ruben calmly went down a small flight of stairs. As he reached the last step he paused, and then jumped with both his hooves into the air, and landed on the grass. "This feels amazing *neeiiiggh" Ruben whinnied, as his hooves felt the soft grass, his tail swinging happily behind him.
Feeling the equine strength in his legs, he neighed. "I want to run!" he said. Ruben picked up some speed and jogged around. The diaper made it quite difficult to comfortably run around, so Ruben decided to take it off. As he reached for the tapes, Ruben noticed that his finger nails haid also turned black and hoove like. He shrugged it off and removed the diaper.
Once again, as soon as it was taken off, the diaper had perfectly folded and cleaned itself again.
Ruben put it on the patio and turned around, eager to stretch his powerful legs!
Then, Ruben ran, as fast as he could!
Tired and panting Ruben returned to his patio, man that felt great! He sat down, carefully to not sit down on his tail, he sat next to the diaper.
That was when he finally noticed his new equine sheath and testicles.
His balls were now larger and completely black, and hang just over the edge of the patio. Impressed by the size, Ruben became a little bit aroused, as he noticed his new equine member, emerging from his shaft.
Completely in awe, Ruben put a hand on his massive horse cock, which sent a shiver down his spine!
Swishing his tail across the patio deck, he then grabbed his massive member and thrusted, feeling a sense of pleasure he had never felt before!
Huffing, puffing and neighing, Ruben pumped his horse cock, standing up and leaning on the railing.
Coming closer and closer to an orgasm, Ruben let go, as a wave of horse cum erupted from his horse cock.
Neighing and braying, Ruben finally calmed down, cum still leaking out of his gigantic member, which now hang still erect between his legs.
