No sucking action but a nice vibe
I was quite surprised the moment I tried it.  This thing is quite intense ... VERY intense, even if you dare to click until 10. Although it is not ~ precisely ~ like "suck" or "suck", it is definitely not so.  Feeling like "just another vibrator", but anyway, I almost screamed in surprise as I started with setting 1: it felt OK.  Perhaps it could be compared to the light, the oral mockery, if his partner could move his tongue at superhuman speeds, haha.  Things started the moment I started, when it usually takes me a long time to prepare. And it's very quiet in setting 1, but it gets stronger and stronger as you move up to 10. It's not like the "engine."  or "freight train", but it makes a little noise.
