Hopefully with a little help, since it isn't that common on this website, could we try to fix the Overstimulation tag to be proper.
The most common term I hear is "Post-Orgasm-Stimulation" which just means stimulation after orgasm, which is overstimulation, plus it's an actual term and not a made up word.
To make it easy to find, aliased terms for this tag would be helpful.

In addition to overstimulation, we have after orgasm torture, which has post_orgasm_torture postorgasm_torture and afterorgasm_torture aliased.
