Anal ball designed G-string One size adjustable.
We refer to Invisible Intrusion as Invisible Exploits evil twin. This design works exactly the same.
The major difference is how the front bikini is held in place. The Invisible Intrusion uses a metal cock ring to get the same effect. Both suits are so amazing and feel so good that it would be hard to recommend one over the other. I know that I will be using both this summer
Depending upon my mood!
