Hello,
what about making a new event type, Stroking, some sort of a klicker game?
On each event occurence you present us with cocks of various harem guys and a hand, maybe some additional toys controlled by mouse/finger on mobile, and players click, do some combo slides to make the cock rise and then explode.
Alternatively this would be a good method of rising a guy's attraction for leveling it's grade.
This would be perfect too for stroking girls in HH
PS. In overal, each guy from the Harem should have a (interactive) photo of his cock(pussy), that we could play with.
