Ja'carr felt the slow buildup of cum as he hammered the young female with his powerful and still growing cock. The female in question has passed out an hour ago from the intense pleasure said cock was giving her. That hour had also seen Ja'carr expand in size. Currently, the young barbarian was around nine feet tall, with muscles larger and harder than the image of the Hulk he had seen in the form of a small statue made of an unknown material here in this room.
Suddenly, the buildup swelled into a mighty flood ready to burst forth from a broken dam, and burst it did. The first shot launched the female off his dick, though thankfully, she landed on the bed covered in his mighty seed. If she had stayed on, she wouldn't have survived what happened next.
Ja'carr's growth started to accelerate, his height shooting up from nine feet, past ten... twelve... fourteen... to eighteen feet. His muscles soon followed, becoming ten times larger than they were at his nine foot form, and five times harder than diamonds. Finally his dick and balls grew, his dick growing from 26" to an eight-foot erect fuckpoll, with balls just big as his now massive biceps.
Having blown through the house, Ja'carr looked around in surprise, before gaining an evil look on his face. He loved the feeling of his body growing, his strength becoming greater than any human on the planet. And he knew what he wanted.
He wanted more.
