Haven't tried yet but pit on my tounge and it takes up quite alot of room in your mouth and the ring slips off the tounge quite easily.
On the tongue is a bit odd but it basically doubles as a cock ring if needed
A little bit tricky to keep on but we'll worth the effort! Absolutely amazing and had me going in minutes
Good experience for the women.
My girlfriend loves this toy. She can't get enough of oral with this. It hits every spot, and makes it easier for you
