" Fine!" you say "get a small bottle, will do."
"Aww..." the woman says with a playful pout "...I was hoping you'd try to be some sort of tough guy and tell me you weren't going to play my stupid game. I would have loooved to see what that." she gives a wistful sigh before shaking her head "Now. You have all day but as soon as night falls you lose, so I'd get going. You'll know when it's too late when..." she giggles slightly "...well you'll know." she says. With that she opens the door and gestures for you to get started. You look down to realize that you're now wearing the black tights and given how tight things are down there you have little doubt where the panties have gone. Where once your bare chest was is now a pink shirt and your feet are jammed into an ill-fitting pair of sneakers.
"You're going to look adorable in these if you fail." the woman says. You run out of the room and start looking all over the house. You move as fast as you can, but given the small shoes you wear, the tights and the women's underwear that's not as fast as you'd like. You try to keep a cool head despite the occasional shift from the magical clothing attached to you, particularly from the panties as though they were trying to stimulate you into distraction.
After quite some time of searching you run into several bottles that might be the bottle she's looking for. In the kitchen you find a soda small soda bottle. You're almost certain that's not it, but you can't really be certain can you? In the study there are six small bottles in a circle. Most of the bedrooms you run enter are locked, but the unlocked ones are mostly empty. The medicine cabinet of one of them, though, does contain a plastic bottle half filled with aspirin. You'd like to keep looking, but a quick glance out the window tells you that you're almost out of time.
