Caught by my sister!

So this was back a few years ago, growing up i was unbelievably horny (still am lol), so started looking for better ways to get off, this lead me to finding my sisters dildo that she kept in her room, it was about 5 inches hot pink with a suction cup base, this exploration for pleasure also lead me to anal which i found i loved.

Anyway one day i think everyones out of the house so decide to get freaky, i go to my fav spot, the bathroom, i liked to sit my self on the dildo on the washing machine so it bounced me around i vibrated in me. Keep in mind im completely naked at this point as i think theres no one around.

After fucking my ass for a while to warm up i get in position on the washing machine, and put my laptop up next to me, playing some generic porn really loud, unlucky for me the washing machine in our bathroom is pointed directly at the door, the door i didnt bother to lock, i think you can see where this is going.

My sister walks in on my right as im getting close, by this point im starting to bounce and frantically rubbing my clit, i also had my eyes closed so didnt even know she was there for a few seconds, immediately she explodes! Screaming st me how disgusting i am and shouting about her dildo, i pannic and slam the laptop shut and shout back at her to go away and leave me alone, i had to stop though out of fear i would moan, by this point i had been going for a while and was getting turned on even further by being shouted at (embarrassment and adjancent stuff is a big kink of mine) so now im jujst trying not to cum, its silent for a sec as i sit there trying not to, my limbs starting to twitch and im starting to wimper, id almost forgotten she was there, before she screams “oh my god your still doing it get of you pervert!” With a look of dissbelied on her face, that unfortunately pushes me over the edge as i moan in her face and have the biggest squirting orgasm all over her

She ran out disgusted and screamed blindly at me, this had all happened in less than 30 seconds and by then i wanted to cry!
