Even as Dustin was growing into a giant Minotaur downstairs, Mark had his own situation to contend with. Since he had discovered that his already large penis and testicles were expanding even larger, his rod had easily grown to two and a half feet long, while his balls had grown to the size of grapefruits. Now he was standing in front of the mirror, holding his penis upright with one hand so he could see himself. So thick, Mark said to himself with awe, as his inflating rod became thicker than his muscular arm. At one point, he was looking eye to eye with the tip of his cock, watching up close as his thick seed continued to pour in thick white spurts. A puddle had formed at his hooves, and yet the organ continued to slowly enlarge.
And as it grew, Mark felt his desire grow as well. The longer he tried to resist jerking off his immense penis, the more he ironically felt the need to cum. He needed to stop this fast, or else he’d be too big. Mark turned to leave the bathroom and had to maneuver his now four-foot long under the door frame, supporting it with both hands, which barely wrapped around it’s considerable girth. Mark heard himself whimper slightly and winced as he felt a sudden shock of climax course through him, and his legs felt weak. When he opened his eyes, his jaw went slack and he found his penis easily as wide as his thigh, and nearly five feet long now. The heavy weight between his legs was a bit painful, and so Mark sat down on his ballooned basketball sized testicles.
He couldn’t take it anymore. He felt like he was going to burst!
