Bit of an older thing I've been revamping to introduce a gorgon character I've had in my head for years named Belladonna. Terry refers to her as "B" or "Belli", as her short-hand names. She produces a potent venom that induces sudden and overwhelming orgasms that could realistically give someone a heart attack.
She's been good to her small boyfriend however, and limits how much she puts into his bloodstream so he can slowly become acclimated to it and receive more and more for better, stronger orgasms. Plus that tail. B)
