This toy is going to be so much fun for solo use or together with a partner ! It's C shape design is What gives it the dual use. Use it just like you would a wireless bullet as it is controlled by its wireless remote ! OR use as a couples toy ! Insert the smaller end and have the larger side sitting directly on top for maximum clitoral stimulation. And when a man enters you as well he will feel the vibration all the way along from the small side that is sitting internally ! You will both have an amazing experience !
