blackmailing my step sister

my name is aron im 18yrs old now im living with my dad and my step mother and sister

my mom died when i was 14 and my dad remarried and bring back a wife and a daughter named suzy

although i didn't like them i had to get along with them somehow for dads sake

suzy was a good student with good mark always although i dint have terrible marks at school but it was still average and not good as suzy

one day i when i returned home early i headed to my room but when i passed suzys room i heard some moan and i got curious and open it a little and found suzy on doggy style getting fucked by a middle aged man hard that i could hear their skin clapping

i never knew this perfect girl could be this slutty so i took my phone and started recording her getting fucked

" yes dady fuck me hard "

" yes slut you really got a tight pussy " saod the man as he kept pounding her hard while pulling her hair

" aaaah im cumming "

" yes come on my dick slut, come on dadys dick " said the man and started grunting and i knew he was cumming too so i stop the recording and closed the door slowly and went in my room and copied the recording in my laptop and saved it

i pulled my short down and pull out my dick from my pants, i started playing the video of suzy and i started masturbating untill i came

i just had to know how good her pussy is and started grinning in my self

at the evening after having dinner i went directly in my room and took my phone and sent a video of her getting fucked in her room to her phone and pulled my short and pants away and started playing with my cock

then suddenly my door opened and suzy entered angry

" you. ..you. ...shameless pervert " said suzy as she saw my cock

" come on its not like you had never seen a cock before " i said as i continue playing with my cock

" cover your self we need to talk " said suzy angry

" there is nothing to talk about sister, did you like the movie i sent you? "

" i want you to delete it now "

"ot seem you didnt get it sister im the one who have the final saying here bitch "

" what do you want? "

" i want you to suck my dick sister " i said while holding my hard dick

" you... how dare you im your sister "

" step sister to ne precise now get here and suck my cock as a good girl if you dont want this video of your to be watched by everybody you know "

" i hate you "

" who care i just wonder how dad is going to do if he see the video of you getting fucked by someone his age "

"okay i will do it "

" now we are talking my dear sister now suck me good "

i sat well at the edge of the bed presenting my cock to her then she knelt and put my cock in her mouth and it felt so good

" that it my slutty sister suck it good " i said putting my hands on her head bobbing it up and down my cock

" your such a pro sister your sucking my cock so well " i said to her smiling at my self

" im close sister be sure to swallow my cum slut " i said to her and pushed my cock in her throat and started struggling but i held her in place with my hands

" im cummmmmming aaah ah ah " i said as i was cumming in her throat and i let her go of her head which left her breathing hard while on her knee

i pulled her up by her hair and pushed her on bed and torn away her shirt and skirt

" what the fuck do you think you aaahhh " said my sister and i slapped her before she finished speaking and looked at me with fear

" shut the fuck up bitch im incharge here " i said and tore her pants and bra and bent down and took her nipple in my mouth and started sucking it while playing with the other with my fingers

after i was satisfied with her nipples i flipped her on doggy style holding her hips on place and pluged my cock in her which made her scream on the pillow

" yes scream for me slut " i said to her

" aaah ah ah aah. "

"do you like it slut, do you like it knowing your brother is fucking your pussy? say it "

" i knew you were a slut when i saw you fucking that man like a bitch you were but now i own you bitch this pussy is mine alone do you hear me? "

" yes yes im your just fuck me "

" thats my slut " i said picking up a speed fucking her hard and fast untill i came in her pussy but i was still hard so i continue fucking her again untill i came again and so did she and i took it out of her pussy and pulled her hairs and turned her to my cock
