A killer pretends to be an insurance salesman to gain entry to Petra’s apartment. Once inside, he slips a knock-out drug into Petra’s drink. After she passes out, he ties her to a chair with a section of her dress, and strangles her by hand to force her to cooperate. Then, he strangles her topless with a necktie, promising to spare her if she cooperates. He orders her to press her breasts together and issues other orders as he strangles her again and again. Then, despite his promises, he decides to strangle her to death, and knots the necktie around her neck so that he can step back to watch the show. As he thought, the beautiful blonde, with oxygen starvation settling in, begins to get off on the autoerotic asphyxia feeling… even to the extent that she presses her hands against her breasts and rubs between her legs, bringing on several orgasms, complete with orgasmic squirts.
This is one of the most erotic Petra videos of all time and a fitting conclusion to the long running “Silk ‘N Blood” series!
