Give her a break

The skinny redhead is a trembling mess. Her entire body glistens with perspiration from too many powerful orgasms. You're pretty sure she's past the point where she's enjoying the orgasmic ****. Strange, that you actually care. But then, you did tell her she was yours: she belongs to you, and you like to take care of your things.

Placing a hand on her head, you stroke her hair gently. "Okay, Skinny. That's enough for you." You pull on her arm, guiding her forward and off of Nicholas's cock. She collapses onto the bed, sliding off of his member with a wet noise and a weak moan.

To Nicholas, you add, "Don't move."

That's when you finally see what you've done to the man's penis. Your thoughts were admittedly a little vague when you slapped him with the "longer and thicker" change. Now you see you need to be a bit more careful with your power.

Nicholas's cock is an angry red color and perfectly rigid. It had to be quite a painful erection for him, which you note with no small amount of satisfaction, but you're astonished at the sheer size. Longer and thicker than ever is a wild understatement. It was comically large; unreasonably large, like a small arm. You can't even understand how Skinny managed to endure it as well as she had.

You turn back to the poor girl. Her eyes are unfocused. Fortunately, your thoughts for her slutification had been very clear in your head, including a pain kink. That cock could have torn her open—maybe it actually did—but the concept you'd **** on her would have somehow enjoyed the sensation. "You're not in any pain. You're not injured." You say gently. To your satisfaction, the girl shudders and relaxes a little, small tears gathering in her eyes.

"Thank you..." she whispers.

You give her another pat on her head and turn to Nicholas, finding yourself unable to tear your eyes away from the accidental monstrosity you've created. There's no way a normal woman could take it comfortably. It's a weapon. It fascinates you. Just imagining trying to fit it inside you invokes the sort of prudent wariness that comes with thinking of touching a hot stove.

You should shrink it back down to something practical. You're still hot and horny, after all, and a nice stiff dicking sounds perfect.

Then another thought occurs to you, as if speaking from a dark corner of your mind: You don't have to change his cock; you can just make yourself able to take it. Aren't you curious what it must feel like? Let him ravage you. Haven't you always wanted a more aggressive, more powerful Nicholas? You can live out all your dark fantasies, even those that would have been literally impossible before the stone.

What could go wrong?
