After a few minutes, Tom started to feel the potion working. His body started to inflated. First his gut, it started to grow. He started to grow a beer gut, Tom patted it, feeling strangely proud of it. All his body was gaining fat. His shape was becoming rounder. The feeling was amazing, he could feel his body growing bigger. His pecs growed, transforming in two enormous balloons of moobs. He took one with his now fat hand and squeeze it. It was a dream come true, he had his owns moobs now, they were his.
Everything in his body was changed to a better version. Even his fingers changed, now looking thicker. Tom went to a mirror and admired himself, fat Tom was hot, he feeled sexier than ever.
After the fattening, the hairy come. He started to feel a tigle around his skin and thousands of hairs started to sprout all over his body.
He gain hair everywhere, in his gut, his shoulders, his ass. A big full beard formed in his face. Tom wasn't able to recognize himself in the mirror. Also, with the hair it also came the smell, his body started to produce a much stronger body odour than before.
The transformation ended and Tom admire the sexy bear of a man that now was looking back at him in the mirror. He feeled heavier and slower than before, which was and odd sensation. But he also manlier and stronger. He was loving his chubby frame, his round bear, his big hairy moobs and his beautiful beard. He even loved his new shoulder hair. He was a beast, a sexy beast.
Looking at himself made him extremely horny and his dick become hard, which now was kind of hidden under his big belly. Tom grabed it and feel it. Even his dick was fatter now, he loved it, that sole idea bring him even more joy. He laid in bed and started jerking off as he feeled his new chubby body. He grabed his fat and smelled his stronger and manlier scent.
