Your roommate just laughs, figuring that you passed out on the couch because you are hungover. What he fails to realize, is that the real reason you are tired is because you spent the day enchanting appliances like the vacuum cleaner he is now using.
You watch in amazement as your roommate shrinks, losing his muscle mass and gaining delicate feminine curves. The neckline of his shirt plunges downward as the buttons become undone to accommodate the sudden growth of two large breasts.
His jeans become tight around his legs as they shrink into a pair of tight shorts that show off slender, hairless legs.
Your roommate continues to giggle as she becomes a complete woman, who loves doing chores like vacuuming the living room.
