The front of the inner ring (where your penis would go) is also covered in soft ticklers! These are going to feel great for her as you thrust in. The bull's two horns are spaced perfectly over the nose, leaving a "clit-sized" spot for her to grind against and really get those vibrations!
I think overall that this product is really well designed to do what it says it will, which is provide awesome clitoral and labial stimulation for her while keeping his cock harder for longer and prolonging his ejaculation so it's also more intense! Who doesn't want that?!?!
