Knowing his son will being putting clothes in the hamper very soon, Paul realizes that he must shrink even more. So he digs down below his shirt and quickly says, "shrink, shrink shrink."
His heads spins as he shrinks down to about 3 inches. He looks down to find he's sitting in Bryan's musky white briefs. He feels himself getting really horny. At that moment the hamper shudders as Don opens the door and walks into the laundrey room.
Paul hear Don throw his clothes on the floor and then feels the rumble as the lid of the hamper is opened. He hears Don say, "Where are they." Paul suddenly sees light through the briefs and knows that for some reason Don has removed the shirt that he had left up there. Don says, "ah, there they are. Better be careful with 'em or Bryan'll think he's shrinking. Hahaha!"
When he heard the word Paul felt dizzy and shrank down to an inch and a half. Then the hamper shook some more as Don moved around out there. Paul thought of scurrying out but was afraid of being seen. Then it was too late Don had picked up the briefs and was carrying Paul joltingly through the air. Light shown down as the briefs were openned. Paul looked and saw Don's monstrous cock staring back at him. He then felt vertigo as the underwear began its ascent up Don's legs and stopped a the knees. "What have we here!" Don was staring right at his father.
