Unexpected Family Fuck.

My sister who is a year older than me have been smoking weed and drinking heavily since high school. I joined her with the practice during our college years with a couple of male friends one of which is my sister's boyfriend 'Jake'. I am not so much into 'Jake' because of how he treated my sister. I nick named him 'Jerk'. She cries alot and whenever i saw her crying i don't have to ask her what is the matter. I just know it's that prick that hurts her feelings.

Why does my sister stay in a toxic relationship when there's other fish in the sea?. I have seen her with one of her coworker who i'm sure would be a better boyfriend than 'Jerk'.
I came home one day only to see her fucking her coworker in the middle of our living room and even when i walked in on them she never stops. After he had left we talked about him, and her only problem with him is his pencil size dick. I then realized she was very high on weed.

Months after that she and Jake had a fight over some girl he's now fucking and that hit my sister really hard. That weekend she took it out on a couple of beers and some weed. I have never seen her cry that much so i gave her my usual consolation hug only to feel her tongue ramming down my throat. I have never been so shocked in my entire life because none of us have ever hinted any kind of attraction towards each other but here she was tonguing me to death.

My cock should never have lifted but when it sprang to life everything between me and my sister changes thereafter. She literally bullied me like a wild animal. She peeled every bit of my clothe then she rode my cock like a tiger. I had no choice but to allow her to fuck me hard then i filled her hole with cum. Even after i ejaculated she were there riding my cock away until she squirted all over me. After she got sobered up the next day she said to me; "i have no apology, i'm glad it happened because it helped me a whole lot"...

I helped my own sister to relieved herself from a very toxic relationship. Our mom is a single parent. She works at a hospital where she does multiple hours per day. She's never at home for more than a couple of hours and that leaves both me and my sister to smoke weed, drink beers and fuck our brains away.
