I'm planning on adding lots of this kind of content in the sex update, which will be the update after next. I want the sex update to be all about exploring & enjoying the bodies of the girls at all their weight stages, so I welcome any and all suggestions for what you'd like to see!
You could make the sex scenes similar to the feeding minigame maybe? Like keep a bar in the green to ensure the partner enjoys it the most. Another thing that could be interesting is like maybe the super concentrated Dizzy's formula -- Hard to get girls hooked on it, but maybe a paid skill or something persuasion based to get it higher than a max of 50%.
And great work too! You've been absolutely cooking up some magnificent updates for us!
