depends on the OC though more often than not the 'fantasies' equate mainly to 'yo would be mad sick if I could animate these interactions/anime opening ahh AMVs with them and my friends' OCs

the major stream/sona ocs which are Noah, Nora, Katherine, Onyx, and their variations all follow that rule

as for some of my more 'alternate story' OCs I also still do more 'character interaction' like fantasies

though as I imagine whoever this mystery person is is most likely asking about the "Caleb, Sonia, Alexis' trio, the fantasies for the ocs-i-made-entirely-for-drawing-lewds are, unsurprisingly, smutty as hell
