Depends on where you are. In some places in the world, into the gulag with them.

In fact, they can get gulaged if they draw a picture of a totally imaginary 16 year old, let alone a real person. It's kind of in dispute in the US, but that'd be the way to bet. 'Course, in a lot of US states, they're also in trouble for having a "partner" at all.

In practice, they'd probably have to distribute the picture somehow to draw the attention to get them arrested, and anyway they'd be a low priority compared to people producing, distributing, or even consuming, you know, real child porn... but if the right official decided to make an example of them, they'd be hosed.
