This is a story about how i blackmailed and used my bitchy big sister as a sex slave.i am Negan.17yrs old skinny but had a 7 inch cock.i live with my parents and my bitchy big sister Rosita.22yrs old.curvy body with big boobs and a big round ass.i never liked her cuz she always makes me bad infront of our parents and get me in trouble.i was always trying to find a way to get my revenge.oneday i saw my sister sneeked her bf in her room when our parents wasnt home.Rositas room and my room had a wall separating two rooms.the wall wasnt so tall so i had an idea.i got a ladder from the basement and peeked over the wall and my eyes almost popped out.Rosita was getting her big butt fucked doggy style.i took my camera and recorded the whole scene.i made several copies in case Rosita might break it.the next day was sunday and our parents went fishing to the lake and wont be back until next morning.so we had the whole house for ourselves.Rosita was in her room.i went and told her it was a gift from me and to watch it.she inserted the tape and pushed play.her eyes almost popped out when she saw her getting fucked on the tape.she screamed and took the tape and broke it.i told her i have more copies and she started crying cuz she knew she was trapped.then she told me what i wanted.i told her from now on she have to do what ever i say and if she doesnt obey then i will show the tape to our parents and she agreed.so i told her to start your new life i want you to remove all your clothes.and refused saying it was disgusting.i told her to not forget about the tape.then she removed all her clothes and stood butt naked infront of me.i sat on a lounge chair in her room and told her to come to me.she started walking towards me and i stopped her and told her to crawl on her hands and knees.she came and stopped between my legs.i took my cock out and slapped on her face.i told her i think you know what to do with a cock.slowly she held my cock in her hand and stroked slowly.the she put my cockhead in her mouth and sucked.then she started really sucking my cock.she was really a pro.she gave me the best blowjob and i came in her mouth.then i told her to get on the bed and masturbate and cum for me.she laid on the bed and spread her legs and started to play with her pussy.it didnt took her long she was squirting cum all over.it was so hot seeing Rosita cum like that.then i told her to take a shower and come in my room but not to wear clothes.i also took a shower and waited for rosita in my room.she came about 45 minutes later.she was looking so fresh.she had make up on and had red lipstick on which made her look so sexy.i told her to lock the room and come on the bed.she came and laid next to me.i kissed her on the lips and she returned the kiss.we started making out.i sucked her big tits and went down licking her hot belly then i began eating her pussy.she had a little patch of pubic hair on top of her pussy but was shaved clean.her pussy was so delicious i couldnt stop eating her pussy.she came squirting on my face several times.then she got up and sucked my cock.i pushed her on the bed and slided my cock in her wet pussy.i fucked her in a slow rythm but she was moaning loudly.then i got between her boobs and tit fucked her big tits.then i got her in doggy style and started to eat her hot ass.i even fucked her ass with my tongue and then finger fucked her ass until she was loose.then i pushed my cock in her ass and fucked her ass hard and fast.i grabbed her big boobs while fucking her ass.i was on the edge of cumming then i pulled my cock out of her ass and turned her around and came on her face.then i told her to take all the cum off her face and eat it and she obliged.then i dragged her into the bathroom and laid her on the floor.then i pissed all over her.even in her mouth and i forced her to swallow it.then i made her piss in a cup and drink all her piss.then i told her to go take a shower and be ready for anything.Then i went out with a friend and hang out for a while.while i was coming back i saw a friend of mine.his name was Rob.he was an old man about 45 yrs.he was a huge black guy.i had a plan to revenge my sister for good.i told everything to Rob and he happily agreed.Rob was a homeless man so he wasnt so clean.i took Rob home into my room and called Rosita.she came wearing a tank top and shorts.i told Rosita i have a friend here and that she was to service him.she knew what i meant and started to plead.i told her about the tape and she started what she was told to.i knew the smell of rob was very disgusting and Rosita will hate it but i loved that.i told Rosita to take his clothes off.she took his shirt off then she knelt down to pull his pants down and a huge bb monster cock jumped out of his pants hitting Rosita in the face.Her eyes were big in horror.even i was shocked to see the size of his cock.it was almost a feet and it was thick as her arm.i told Rosita to suck his cock.she hated it but she had no choice so she tried to suck but all she got in her mouth was his cockhead.after a while i told Rob to turn and bend on the edge of the bed.i told Rosita to eat his ass.even i could smell the shit aroma that was coming from Robs ass. But Rosita began eating his ass.i told her to jerk his cock while eating his ass.i made her eat his ass for about 10 minutes.then i told Rosita to get on the bed and spread her legs on the edge of the bed.Rob took her clothes off and ate her pussy before sliding his huge monster in her pussy.It went only half in her pussy.Rob fucked her pussy for a while until i told him to turn her into doggy style.he fucked her pussy in doggy style.i knew she was liking the huge cock in her pussy.so i told Rob to fuck her ass and Rosita tried to get away but Rob held her and fingered her ass with 3 of his big fingers.then he slowly pushed his cockhead in her ass.it was so tight.she was now crying.but Rob didnt stop.he just pushed and pushed until he couldnt get anymore of his cock in her tight ass.then he began fucking her ass slowly.she was still crying and trying to getaway but Rob was too strong.then he started fucking her ass hard and fast until he came deep in her ass.i told Rosita to take all the cum out of her ass and swallow it and she did.i saw her ass.her asshole was gaped open and there were some traces of blood and shit.Rob left and i told Rosita to take a shower and rest until i say.that night after dinner i went to her room and apologized for everything but she didnt say a word.i even gave her all the copies and said that what i did was to take revenge cuz she always hurted me.and that i love her.and i left to sleep.i woke up feeling someone touching me.i looked down and saw Rosita stroking my cock.i never wear anything to sleep.she was butt naked.she gave me a blowjob before riding my cock i her pussy then in her hot ass until i came in her ass.that night we forgave each other and started our relationship as secret lovers.when ever our parents go out we fuck.they never found out about us.
