They left for a guest bedroom and Andy waited a minute before following. He was only half aware of what he was doing. In a more reflective state, he might have realized how strange it was to watch his cousin get her diaper changed. But he was acting on impulse now and a desire to be in her place.
Either embarrassment, guilt or fear kept Andy from actually watching what was happening. He stood just outside the doorway and listened. There was more bickering between the two sisters, then he heard the rustling of plastic as Libby’s leggings were pulled down. The popping of tapes followed, then more rustling, then, a moment later, some unexpectedly quick footsteps.
