Of course it was forced, in that consent simply cannot exist in such a situation, and the 12 year old doesn't have the capacity to object to the advances of an adult. Saying it isn't "forceful" because she didn't torture him or something misses the point entirely, which is that an adult used her position as an authority figure (parent of a friend) to rape a twelve year old.
There really is no excuse for being a rape apologist.
