Vibrator Suggestions

My boyfriend likes to tease me hardcore and he’s into the idea of doing the do in public spaces. Like obviously not out in the open where anyone could see but still, not in the privacy of home either. And I’m actually kind of into the idea too, I’d at least be open to try it. He would like to get a vibrator that he can remotely control so he can tease me in public. I’m down for this but I’m a little nervous about the noise. What’s the best vibrators for some risqué but discreet public teasing?
