Input: Text: this fuck up happened about an hour ago. 
my girlfriend and i are at her house and decided to have a little fun time for the second time today. keep in mind, she lives with her parents who were away at the time. in the past few weeks, my girlfriend's parents bought a new mattress and box spring for their room. my girlfriend's parents didn't want to discard their old set so they stacked it beneath her existing mattress and box spring. as a result, her mattress is at least four feet off the floor. 

earlier in the day, she told me that she didn't want to turn off the ceiling fan (full speed, this is texas) while we had fun together the first time. because of that, i didn't bother asking about the ceiling fan the second time. my girlfriend got on her hands and knees in the bed, and i got behind her, aware of the spinning blades in close proximity to my head. unfortunately, about 20 seconds into the deed, i realized that i needed to adjust my body slightly. i ignore the concept of situational awareness as i'm trying to adjust to the position of maximum pleasure and comfort. the next thing i hear is a loud whack, my head immediately begins throbbing, and dust starts to rain down onto the playing field. my girlfriend flips out and asks if i'm okay. i try to play it off because, sex (and embarrassment), but i'm definitely hurting. my girlfriend gets away from me and examines my head. the result is several bleeding scratches (bleeding has ceased), two bumps, and a lingering headache on the left side of my head.

and no, we didn't finish fun time.
