Irwin's Revenge

While having sex with the mouth of a stingray, you stab it's barb into itself while you climax. This causes the stingray to tense up, maximizing your pleasure. Named in honor of the late Steve Irwin.

After noodling a stingray at the beach, you decide to have "Irwin's Revenge" with it. After flipping it on its back, you force your dick into its mouth. As you climax, you stab it in the chest with its own barb.
