I recently discovered that there are actually 2 versions of the high lust fellatio scene. The one that's easier to trigger is the one where the game gives you the "To bed" option after the fellatio scene. The other one is where she gives you 2 blowjobs :). You just have to insert your finger in her mouth and press the "receive oral" during nighttime.

I find that blue flowers are more frequent than pink ones. You can buy the apron from the shop.
