First time my mother caught me and my step brother

Me and my step brother used to arguee alot he hated me that was untill i started growing tits when we where young he teach me sex things but thats for another day today im talking about when my mother caught us

That day it was really hot so we staye dinside whilst mom was outside
My step brother came in to my room with his hard throbbing dick out of his jeans i was in shock we never did it when mom was in
He tell me to be quite and slams me against the wall pulling my mini skirt up revealing my wet panties
He slides them off really quick and whispers in my ear u ready to try it this way

He has big muscles and lifts me onto his dick very sloly and holds me by my legs my back arched against the wall
We are going at it as quite as we can then i notice my door was slightly open
I tried to tell him but he kept telling me shhhh
I wrap my arms round his shoulders as hes fucking me really hard i notice my door is open and my mom is standing there watching me
Again i tried telling him but he kept saying shhhhh theyll here us

I keep making eye contact with ,y mother as she lift her finger to her lips basicly telling me to shut up
Me step brothers getting deeper and deeper my arms still covering so he could not see my mother
Then i glance down my mother has her hand down her panties she was fingering herself whilst i was getting fucked
I couldnt belive it i watched as she made her orgasm face and quietly left

My step b*o shoves me down before i could say anything he rams his dick inside me and shoots his load all over my lips

Still to this day my step brother doesnt know what happend but me and my mom have alot more to talk about
