One Direction toilet training

Excerpt:
"Do you need the loo Niall?" 'Niall's face conveyed a look of horror, although they sometimes babied him he was an eighteen year old boy, he could control his own bodily functions.

"Don't look so shocked love, it is me and Liam who do the washing and we know about your accidents sometimes' Zayne replied, climbing into the bed.

There's a tiny but impassioned subset of the One Direction fanfiction universe that loves age play. Sometimes members of the band are actual children and the others are parents, and sometimes they just pretend to be dads and kids. And then they make out a lot. This one stands out above the rest because it actually involves diaper changes among members of the fivesome.

Niall still pees the bed, so Zayne and Liam put him in nappies and give him blankets and soothers. Harry and Louis act as surrogate big brothers in this makeshift family. And then everyone smooches.
