Aftercare: It feels just as good to give aftercare as it does to receive it. Showing your Sub that you value her and what you’ve just done together is incredibly rewarding.
Aftercare is so much more rewarding than any vanilla cuddling can be. The true reward of BDSM, for both (etc.) parties. To know that one is still cared for after either doing “terrible” things or having such things done to them is the sort of validation the waking world cannot imagine.
