I'm looking for a story that I don't think I originally read on this site. I believe it was called I/O suit and was about a woman who orders a voice controlled catsuit. She puts it on and her friends arrive unexpectedly. She hides the suit under her clothes, but her friends' conversation accidentally triggers features in the suit, locking it onto her and stimulating her.
Hi. I'm not sure, but maybe it's "Voice-Activated - NON CANON" by lonelyzentai from deviantart?
That looks close to what you described.
PS It says that I can't post links, so only name, author and site.
