The profile of this toy makes you open up little by little, as it is quite progressive, reaching 89mm measured in the widest part of the toy. Once it has pierced you, the wide base of support reminds you that it is inside you. Going in and out repeatedly makes the anus ready to risk a little more. This toy is essential as you go up because it prepares you perfectly. And after 30 days of inactivity it becomes even more necessary. I hope you like it. Comments welcome.
