As someone with BDSM interests as well as feedism, I’m all about two BDSM themes showing up more often in feedism:
1) Safe words - If I’m enjoying stuffing you silly, “stop” is just going to make me wanna keep going. Safe words are important! Establish them beforehand, maybe have one that serves as a warning (”I’m getting close to my limit”) and one that means you’re done. Respect the safe word!!!
2) Aftercare - Intense stuffing, teasing, and maybe even physical pain (slapping or pinching their belly, restraining them, etc) require a recovery and reconnect afterward. How are you each feeling? What do you need? Water? Rest? Watch an episode of a funny show together? Cuddling?
These things can also be done over skype/text and they’re still important in those cases as well. A scene is a scene is a scene.
