[MF] walking in on my sister ( 19 ) and staying

To start there is a 6year age gap with me and my sister, me being the older one. My sister has a slim figure with a bubble butt and handfull size breast. My sister has never been a crazying party girl. All throughout highschool shes been a good student working hard to get into college. Shes really only ever hung out with female friends and never brought home a boyfriend or ever even mentioned one.

Shes been such a girl throughout her life never getting into trouble that when my partents decided to go on a 2 week vacation, they had no problem leaving her alone asking me only to check up on her once a week to make sure she wasnt to lonely. They told her she could have friends over to study but no praties.

Two days after they left I decided to stop in and bring my sister diner since she wasnt a great cook. We ate, played a board, and watched tv. Friday that same week I decided to buy some come ingredientes for pasta and breaded chicken since im not a great cook either but i can make simple foods and we could have a movie night . I didnt know her school schedule so i decided to get there at 2 since i had a key so i get things ready and the food would be ready by the time she got back. While I was looking for pot for the pasted i heard a noise coming from a different part of the house and went to find out what it was. I followed the noise to my sisters room and when i cracked the door open (keep in mind i thought she was in class or i would have knocked) she was on all fours on her bed getting fucked by some random guy.

I pushed the door wild open and yelled ” what are you doing”. The guy jumped back and i noticed he wasnt even wearing a condom. She had the nerve to shhh me, grab his dick and put it back in her pussy and say ” keep going its just my brother”. I was shocked. She said something else but i was too distracted by her ass bouncing as he fucked her. She noticed I was getting hard and started laughing. She said “what are you going to do just stand there and watch?!”. I dont know what came over me but i just took out my dick and started jerking off. She just smiled and gestured for me to come closer and started sucking my dick while making eye contact. I pushed her head down and after gaging for a bit she came back and said “its okay this isnt the first time, he always pulls out” and continued to lick and suck my balls. She gave me oral the rest of the time until he finally came on her back.

He left, she went to shower, and i went to finish making the food. She acted as if nothing happened. I tried bring it up while we were watching a movie and she just said “awww is someone in a bad mood because he didnt cum”. She unbuttoned my pants and started to take them off. I grabed my pants and asked what she was doing. She responded saying “dont worry i know what lips will make you cum” and took off her pants and panties. She grabrd my dick and started to jerk me off untill i was hard enough to ride. Once she started riding me she got fully naked and inbetween her moans started telling me why i couldnt tell our parents about him that they werent serious and he was just sexual release mom and dad couldnt know.

She kept pressing her boobs on my face and i couldnt get a world out. I ended up realizing i didnt have a condom and tried pushing her off but she was starting to cum and ended up riding me harder and harder which ended up making me cum inside her. She riding a while longer till she finally climaxed. When she finally got up she wiped up the cum leaking out of her pussy with her finger and licked it with her tounge and sucked her finger. She turned and started heading for the shower and all she said was “we’ll fix that for next time….. you’re so close to getting squrted on”. I was left on the couch dumbfounded
