Adult Film Star Builds a Darth Vader Replica Using Only Sex Toys
In honor of the upcoming Star Wars film, adult film star Kayla-Jane Danger, thought she’d get everyone hyped about the film in a way only a porn star could: by creating a replica Darth Vader using nothing but sex toys.
It’s called “Dart Vibrader”, because of course it is.
