Valentina comes back home; she didn't notice a creep is following her. Once she gets through her door, the creep rushes in and ties her wrists and ankles up. She lays on the ground and cannot escape now, just protest and swear at him.
He takes off her sneakers and gropes her feet, sniffs them. He slowly removes her socks and worships her soles and toes.

Valentina keeps protesting, and at some point the creep decides to chloroform in order to have some peace; after that, he goes on groping and worshipping her limp feet... he starts fucking her soles by sliding his penis between them, but after a while she wakes up, and starts protesting again. He seems to be turned on by her pleads and goes on fucking her powerless feet, as she goes on protesting. He goes on fucking her soles and slapping his dick on them, until he cums all over them, leaving her tied up in a big mess.

Time to go, but she has seen his face, so before leaving he gets the other end of the wrist rope, and strangles her to death. Valentina beautifully struggles for a while, but she's still tied up so there is nothing she can do and eventually she is dead. he leaves, and the camera pans on her dead body and soles still wet with cum.
