It's increasingly difficult to come up with effective fantasies to arouse myself as I get older, but the other day I came up with one that is incredibly effective for some reason. I imagine an attractive woman starring in a shampoo commercial. The director wants her to have a more orgasmic face, so they get somebody to stimulate her breasts from behind. Of course then they start to stimulate her pussy and eventually begin fucking her full on. It results in the most successful commercial ever. I'm not sure why I find this scenario so hot.
