You wake up alone

You wake up alone in bed. Next to you, the only sign someone was there are some hairs on the headpillow and a damp spot near where a person's crotch would be. Upon observation, it's the same liquid you had cleaned off your own arm the night before, and seemed to of been leaking out of Holly's pussy.

Understandably so...

Because of your girlfriend-diagnosed condition, she intentionally withholds sex from you, and by consequence, herself. This is what helps you get through it in thought...that she is suffering the same clinical treatment you are. At least for penetration. Since she isn't "afflicted", you justify giving her oral sex when you yourself cannot. She's been incredibly sloppy every time she asks for oral, similar to the goo all over your arm and her inner thighs the night before.

Again, you justify it by understanding her unanswered arousal.

You leave the room to find your roommate, Joey, and girlfriend talking in the living room.
