Fill your hole to the brim and stretch it to the max with the incredible Mega Insta-Gaper! Once you squeeze the tips together and shove this bad boy deep inside your ass, the plug instantly springs open and stretches your cavity to gaping widths that you never thought were possible. The silky-smooth silicone feels great once it's inside of you, while the arms expand to create an amazing feeling of fullness. The Mega Insta-Gaper features a narrow neck that allows your sphincter muscles to wrap around and hold it in, while the wide base ensures it won't slip too far in while still fitting comfortably between your cheeks. The super-strong suction cup base sticks to nearly any flat surface for a wild ride every time! Our ultra-hygienic Elite Silicone is phthalate-free, hypoallergenic, and can be worn all day for long-lasting fun.
