Yes. When I used it, it was afternoon, and I told her to leave it in and then the day switched to evening. So I waited until the next morning to talk to Lin again and the option to remove the vibe wasn't available nor could I use it anymore. I went to my room and checked to see if I could buy it again from the online store, but I couldn't. So, if the day progresses and Lin leaves the kitchen, without you removing the vibe, the vibrator option goes away. I saved the game during the morning phase, so I could modify the savefile so Lin was wearing the vibrator again, and then when I reloaded the savefile, I could remove the vibrator from Lin and afterwards, the option worked normally.
So... I guess in brief, if Lin is wearing the vibe and you fail to remove it before afternoon changes to evening, the flag is set as if she isn't wearing the vibe anymore, but the flag for you using the vibe on her is still set, so they conflict. So you can no longer use it nor remove it from her. That's why I had to modify the savefile.
I hope that explains it better!
