Input: Text: so as a bit of context let me start by saying that my father currently is a christian anglican minister and also works part time as a army chaplin and police chaplin so needless to say he is a bit of a tight ass. to make things worse we haven't exactly gotten along since i became an atheist and i’m also not a angel child so relations are kinda strained.

anyway to the story. so i have been seeing my girlfriend for almost eight months now and she live about an hour and a half away so i only get to see her on weekends. when we do see each other however things get pretty heated very easily and sex is a regular occurrence on such meetings and up until last night we have been pretty good with no one finding out. 

so she is over at my house and i’m during the middle of an exam period so she is over to help me "study" so we do a little bit of study then i get bored and decide to watch a video or two with her however she has a horrible attention span and she pauses it and start making out with me and one thing leads to another and so yeah sex. 

it was about 10 pm and my dad had work the next day (he's a minister so he works on sundays) and had told me he was going to sleep so i thought i was all good and safe. it’s also easy to tell when he is walking around i have wooden floor boards and he has heavy footsteps so he can be heard from a mile away. tonight that was not the case.

so i’m having some great sex and my minds on other things, either i wasn't paying attention or my dad went full military police ninja mode. i hear the door open out of nowhere and i look up to see my father’s look of anger, confusion and disappointment all contorted into one hell of a nightmare face that i’m sure i will remember forever. he slams the door shut and storms off whilst i’m still bewildered and utterly shitting myself.

after some cleaning up and redressing i go and talk to him as commanded. things get pretty heated and i mostly sit in silence whilst he raves on about how furious and disappointed he is in me and then tell me to get out of his sight. my mum however was all nice about it and consoles my girlfriend and i a bit which was nice.

so i barely slept a wink last night just thinking all of the great ways my dad is thinking of crucifying me. the next morning he comes into my room again says how mad and disappointed he is in me then leaves for work. so i walked my girlfriend to the train station and kinda worked things out a bit with her. now i sit in my room trying to study for my exam tomorrow and bloody dreading when my dad will get back from work.

TIFU by having sex with my girlfriend when i thought my crazy conservative dad was asleep
