Input: Text: like many a tifu, this one actually happened a couple days ago. sunday, to be precise. it was my 18th birthday and my girlfriend of 3 years came over for lobster and ice cream. 

my parents are really lax about sex and intimacy, so it's not uncommon for one of us to sit on the sink counter and talk to the other while they take a shower. we shoot the shit and discuss whatever's on our minds. today, however, she was a little more frisky than usual (and she's got a fair-sized libido) and she motioned for me to get out of the shower. one thing led to another and we started making out while i was still slimy*  from body wash not being body washed. we hurriedly tiptoed across the hall to my room and gently closed the door behind us. 

mind you, she's on her period, so sex is essentially out of the question, but she does that thing with her mouth that i have 'come' to love so much. she had me on my back for the whole thing and proceeded to lick, rather than suck. whereas i'm not going to complain, i noticed the danger. i wasn't about to stop this, though, and i suffered the consequences.

not a minute later, i came to too late - much like a 1950s doctor being assaulted by a patient with a history of heroin addiction and violent outbursts - and received a dose of my own medicine. 

in my mouth, on my bedsheets: it was everywhere. she was extremely embarrassed, but i thought it made a good story. 

my first post, so be gentle.
