You are sitting in a chair, and lean back in the chair stretching back in the chair while arching your back and neck. Cassandra up from the side and starts kissing and licking your neck (yes, you’ve done this before, but you have one of the sexiest reactions to having your neck kissed and your arched neck is hot!) The camera zooms in close with your neck fully arched back. And then camera goes down and looks up at you that shows your neck fully bend back. Make sure at some points you state how good it feels.
