If you hit the buttons just right, then you can make it simulating as if you are having sex and honestly I love that about this. It has three really deep in tensing sucking motions that will have you curling your feet for more.
You are also going to need lube because well, without lube it is hard to slide into so be sure to use water based lube because silicone lubes will eat silicone toys.
This toy had my husband curling his feet because it felt so good that he did not want to stop. You can always use this first to get him hard and then jump on it and ride because it makes him rock hard.
