I can think of distinct approaches to engineering that suspension of disbelief:
* The long, slow, inevitable attraction.
* Deliberate targeting and seduction.
* They just fell into it; it seemed natural.
* The inadvertent fuck; they didn't know they were related.
* The belated reunion; it's been a long time.
* Something snapped and they fucked.
* It was an accident; they slipped.
* Some mind-control or hypnosis trick.
* Others maneuvered them together.
Some of those work better if they're drunk or stoned. Two I *don't* like are:
* They saw each other naked and were overwhelmed with lust.
* It's a long family / community tradition, a rite of passage.
Yeah sure, those can be finessed, but still...
