Not a lot honestly. Celeste, Melody, and Cinn are really meant to be 'guests' that were really just added for fun. But there will eventually be sex scenes with both if that is what you're asking. Not a lot of 'story arc' stuff.
Cool, Thanks for putting this query of mine to bed. In my opinion, your work is still the best, I'm with you all the way, Keep up the good work.
