So many thoughts rushing through your head. You're not sure if you wished Mack would go away, or if you'd change back or what, when you flipped the coin. But it doesn't matter it came up tails.
"Oh, man, what's that smell?" Mack asks pressing against the door.
You realize you're now emitting pheromones. The door creaks, as Mack presses against it.
Maybe if Mack was a total wimp, you could handle him.
"I wish Mack was a submissive little kid," you say flipping the coin.
"Dang, how many times will this coin come up tails?"
There is the sound of cracking wood, you step back as the door is ripped off its hinges. A 25 year old version muscled of Mack stands in front of you, looking a lot like the incredible Hulk with his shirt and pants torn apart by his sudden growth spurt.
"I knew I was right! Now to deal with that chastity belt!" he says grabbing you.
