In some fantasy universes and occult traditions, the energy of orgasm is a powerful aid to magic. I want to see this with the force-- force sensitive partner needs to do something particularly intense/hard and needs the extra boost of an orgasm, other partner gladly (or grumpily if Hux, because let's be real here) assists.

Anon prefers Rey with Finn and/or Poe or Kylo with Hux and/or Phasma.
