Adele stands up and tells you to stay seated. She completely strips of all clothes, causing you to get a boner. She smiles as she notices the "attention" that she's getting, and grips her wand firmly. You hear her say "Ich wünschte, ich war wirklich muskulös." You don't know what she said, but you're pretty sure it will have interesting results.
You both watch as her skin seems to tighten some, but then to grow a little larger. It doesn't grow as fat would, with no shape. It's defined, chiseled. You watch as her biceps get larger, thicker, looking like they would be able to knock someone out in one punch. You look down to her legs, and watch as her calves get defined some, slimming in some places while thickening in others. They look like they could steadily run for miles.
Adele turns around, showing her now perfectly sculpted ass. You give it a slap, but it doesn't jiggle at all. She turns around again, this time looking at her belly. All of the fat is gone, replaced by a solid six-pack. You rub a hand on it, and are surised at how hard it is. You look up to see that Adele is smiling, and yelp in surprise as she grabs your cock with both hands. She starts vigorously giving you a handjob, making you moan in pleasure at the pure intensity of the force on your dick.
After a minute of the most powerful handjob on the planet, you blow your load all over her face. She smiles after you finish, and gives you the list of transformations. Not even thinking, you randomly pick an item from the list and wish for it to happen.
