I'm BIG on aftercare, consent, respecting limits... ALL of it regardless of the type of session I am doing.
It is especially important when you are engaging in intense sessions. However, clear boundaries, great communication, check-ins, reintegrating consent, and aftercare is for EVERYONE involved in the session and not just for the ticklees.
That being said, I really like giving aftercare, especially to lers. I believe providing snacks and drinks to recharge is bare minimum. (Fun to ask them about their favorites to eat, though) I love to cuddle and give massages too if that is what is preferred. I just like making play partners feel appreciated and warm.
Now.... I feel like many on this thread are responding in regards to models after a paid gig. Sometimes things are the same. However, often times when you are dealing with someone who isn't a model, things could be different. Building connections first and reinforcing them afterwards always help when having a session.
Finally, I do want to echo that respecting boundaries is non-negotiable or it's sexual abuse considering that this is a fetish for many.
