Hello,
it's a very intriguing game!
Is it possible to know if full lesbian playthrough is possible or is M/F scenes unavoidable?
Cheers,
It's possible. If you avoid adding any pink cards to to Princess's subconscious she won't accept any random offers for sex during random events. Then just pick your woman love interest of choice, (The PC, Evette, Amelia, or Cecily if futas are okay with you) and pursue it. Also be careful about what trainer you have.
