Stories are masturbation.

In the form of novels and movies, tv and video games they are super-refined hyper-palatable food for our emotions and sense of self.

Sport is the masturbation of physical activity.

They are the closest we can come to wireheading using only culture.

Figure out what we like devoid of its evolutionary function, and do it to please ourselves until satiated. Invent new more refined ways to vary the pleasure. Do them with different people in different combinations (not masturbatory then I guess). Music. Art. Cuisine.

Anyway, I think stories are the most interesting version because they are so closely connected with how we perceive and assign meaning, so there is a whole added level of complexity above simple pleasurable sensations.
