You watch in the mirror as you grow taller which is what you expect but what you don't expect is the random stubble appearing on your face. "What the?" You say aloud. Jimmy wasn't hairy so you weren't too sure who you were turning into but the next few minutes would made it clearly obvious.
You groan in pain as you continue to grow until your head nearly touches the ceiling. "I always knew we had a small bathroom" you say as you feel more hair erupting over your body. Your hair had turned into an orange hue and you now had a well developed beard on your face.
You watch as a multitude of hair spread on your chest and stomach as well as your forearms and legs. Your also gain an enormous bush of pubes and watch in amazement when the hair growth ends. "Woah! I look like a sasquatch" you say. You were now an extremely tall hairy ginger man. But the changes were just beginning,
You watch your jawline develop as well as your ears grow. They stick out a bit like Jimmy's but not as much. Your eyes turn a shade of blue and your hair grows shorter. Your skin also becomes more paler but to a less degree Jimmy's was. But you still see a myriad of freckles erupt on your skin. Then the ultimate changes begin. You feel your body shake and rumble as you gain weight. Your stomach expands as you begin to gain layers of fat. You watch your previous prominent jawline grow chubbier.

Then you watch as your dick grows almost five inches and your balls grow to the size of ping pong balls. You moan as your voice grows deeper and the changes end.
You look at your reflection now recognizing who you were. "I'm Jimmy's dad!" You say in a deep baritone voice. You were a enormous hairy man with a protruding gut. You feel the ground shake with every step you take as if the floor is accustoming to your newly developed weight. "Oh no! I didn't want to be Jimmy's dad" you said. You shake you new flab and watch in fascination as your body jiggles. You were a hairy weary middle aged man. "Man now I know how dad feels" you say continuing to examine you body.
You gaze at your new package. Like Jimmy's it was long but his dad's was apparently thicker. "Should I-" you pondered as your dick began to drip precum in arousal. You open the door and sneak into your room. You lay on your bed which creaks to your new weight. You take your larger and harrier hand and begin to stroke you dick. "Why do I feel so aroused in this body?" You think as you edge. Suddenly an eruption of cum releases and you become drenched in it.
You lay in bed tired when...
