Input: Text: this just happened. still in hiding in shame. luckily this is technically the weekend in the uk by an hour, so i can post it now.

some background: i am at university, in a house of 6 friends, its normally pretty relaxed, socialising mostly downstairs in the evenings, and respecting each others privacy. not today.
its coming up to exam term, so i am spending the majority of my time in my room working. being a long-time-single male, i have learned, and practiced to perfection, the best way to achieve sexual enlightenment by myself in this house, whilst keeping any noise to an absolute minimum. proper tom cruise mission impossible stealth shit going on right here.
the walls are quite thin, so headphones are a must if perusing some of the internets less pg sites for inspiration.

the fuck up: it was about midnight, i had just finished my work. i decided now was the perfect opportunity for some 'private reflection time' before heading to bed. normal service is resumed, headphones on, choice material selected, the journey has begun. i am sitting on the far side, at my desk, in my high, wide backed office chair, frankly loving life.
my housemate at this point chooses to ignore the age old tradition of knocking on a door, and enters the room to invite me to join him for a cigarette outside (we use it as a study break, and are both pretty nocturnal), still none the wiser to the sinful acts unfolding just meters away.
for my part, i was blissfully unaware of his presence due to the silicone-fueled filth blasting in my ears.
i was verging the point of no return, so made preparations for the oncoming event by reaching for my trusty box of tissues.

*this resulted in me spinning a full 180 in my chair, and masturbating furiously directly at my housemate.*

i'm thanking every god i've ever heard of i didn't finish or i think i would have to move out. i haven't left my room since, and i'm not sure i ever will again.
