You finally form a mental picture of Erica, but what comes to your mind is a picture of Erica in the same "fuck me!" outfit that she always used to tease you, and it doesn't help you calm down any.
Picturing Erica in this outfit always seems makes you feel like you are masturbating. The association with this lingerie and her forced masturbation sessions is so strong.
You toss and turn, trying to remember wholesome and pure thoughts about when you first met Erica, before she became a porn star ...
And eventually you fall asleep.
