australian time by the way.

it happened after work, my coworker ( my fwb) and i agreed that we'll do some lessons tonight. so we drove to our usual spot, turned off the ignition, went to the backseat and i started giving him a bj. 
basically after giving him a 10 minute bj  and a bit of making out and groping,  we took our clothes off and started doing it missionary style. 


as we're getting it on, he said that i was really wet and i agreed telling him i'm really horny. 
but holy mother of pearl, when i reached down at the apex of my thighs,  i have a red bloody hand...

i loudly yelled stop. 
he noticed my hand was red and he knew... i have my fucking period.

i started apologising but to my utter surprise his reaction was "i don't care, i'll just wash off when i get home"

so we pretty much continued our liaison. 

tl ;dr: had sexy time with my coworker at the back of his car and he didn't care about plunging in the red sea. got home and i notice that i became red-handed jill.

TIFU by having sex in the backseat of the car while not knowing... That... *Sigh* [NSFW]
