Just add water and enjoy the sensational stimulation of CHU ! WET. You do not need lotion, just add water and dive right into the action. Made with G Projects popular momochi material. (Please note that while this masturbator can be used multiple times, it is actually designed for a one time use only)
It is very compact, not the most comfortable, but it does the job well enough. I didn't find any significant discomfort while using it. All around quite nice.
To go down more than half way would 'cause the top part to get stretched way to tight and cause a great deal of discomfort at the end of the dick.
