Well, the edging ability has been added, but it doesn't significantly prolong the encounters. The only satisfyingly long sex scenes are the ones involving multiple partners, as it appears their overall pleasure gauge is a simple multiplication of NPC participants. And so far the only consensual gangbang scene featuring up to 6 NPCs is the Swimming Pool lockers scene which may be played twice a weekday, before and after the swimming lessons. One on one sex for S-class PCs are disappointing quickies.
IMO, the sex encounter mechanics, which is the core of the game after all, need upgrading to include new positions (especially for male PCs), action/position requests/demands (just like asking to be choked) for experienced and confident PCs, use of toys (perhaps even furniture pieces in certain areas, just like wooden horse and stocks).
