Jim offered to carry Marie's leggings for her and she bashfully agreed, the boy carrying both his lazily folded jeans and her leggings as they walked out of the bathroom. Bathroom diapers were more cheaply made than the kind his parents got for him at the grocery store, so the padding between his and Marie's legs were a lot thinner than what they wore, almost pull-up like. Unlike Marie, Jim's lack of pants were more noticeable and he blushed a little. It wasn't illegal for someone to walk around in a bare diaper (at least not in this town), though he was still a boy walking around in nothing but his underwear.

Neither of them were in the mood for more snacks, though they did agree to split a large soda.

Thankfully, their original seats were as unoccupied as they left them and they got comfortable on the beanbag chair. Their legs, now naked, touch each other from thigh to knee and the both of them got goosebumps from this sudden intimacy. Jim tried to pull his sweater down as nonchalantly as he could, the padding of his cheap diaper suddenly feeling tighter.
