Dave continued to fuck James in the ass, watching the man become more satyr like as the fucking continued. James' back was becoming covered with a thin line of hair growing down the middle and spreading across his muscular back. His legs were becoming more muscular and were covered with a thick grey-blonde fur. Dave was about to cum in James' now very hairy ass when Randy the mailroom boy walked in.
"What the fuck is going on", exclaimed Randy in astonishment. All he could see around him were very hairy men and half-men half-women ripping their clothes off and having all the different kinds of sex you can imagine. Janet was now totally male. The former female secretary had a 10" cock and balls the size of oranges dangling between her hairy muscular legs. She had spread the cheeks of Robert the shift supervisor and was lustily fucking him in his hairy ass. Horns were sprouting on Robert's head and his legs were already shaggy goat legs. He was moaning in pleasure.
Randy turned to leave when Dave walked up next to him and Randy's changes began. First his face sprouted a full thick beard where only a trace of hair had been before. His chest broaden and popped the buttons of his white dress shirt. With his shirt in tatters, thick hair now appeared on his chest and moved down over his forming six pack abs. The changes continued as it hit his crotch. His cock expanded to 11" and his balls to the size of grapefruits. His pants could no longer contain his large equipment and his expanding thighs, and his pants ripped away in shreds. His legs were now covered in thick hair and his feet were beginning to change into goat hooves. He was watching in amazement as the changes progressed down his body. He began to get a lusty look in his eye and with his cock engorging, Dave knew what he wanted.
