Help a sister out

Your name is (y/n) and your 20 with a decent job and a couple close friends and you currently live in a shared apartment with your porn star sister how ever this isnt a standard liveing arangment as you both use eachother whenever you want forrrrrrrr.....lets say...relief and no one else knows about it.

"Im hoooooome" (y/n) yelled from the apartment front door dropping his coat on the rack and shoes at the front. "Hiiiiii" bella yelled with a happy tone from the kitchen as she was cooking her favourite meal for dinner tonight and of course in the complete nude with just an apron.

"Damn you look sexy id rather eat you instead tonight" (y/n) said whilst coming up behind bella and giving her a quick grab to the right tit and slap to the ass "fucking perv" bellas words juxtaposed with a cute horny smile ."you love it.ughhh jesus you wont believe the day i had today bella" (y/n) and bella where very open about what they did outside of work. "why what happened?" Bella said whilst not moving from the stove.

"Right so basically i was out in town looking for some food for tommorow night and then at the checkout i saw this gorgeous bbw girl infront of me with the most fatest ass youve ever seen. And not only was she big and curvy like i like them but also she had a gorgeous face with a belly i just wanted to kiss and play with" (y/n) said with a semi.

"Well dont just leave me on edge what happens next? Did you ask her out." Bella asked knowing what the actual answer which waaaaaas....

"I fucked her and got her instagram" (y/n) said with an evil grin

"Didnt even know why i asked to be honest" bella said almost sounding dissapointed in him.

"Awwwww is little siter jealous cus she isnt getting enough attention because no matter how much of that girl there was to love she had to get back home to her boyfriend?"

"First of all that turns me on a little which isnt fair and second im not jealous cus you always come to your sister for a fuck and relief instead of your girlfriend which is a bit sad bestie"

"You lieing bitch.your the one always sitting and rubbing on my lap or putting my hand down your pants during a movie."

"Well lets just agree where disgust in our gross sexual incestual adventures" bella said putting his hands up

"Mhm yep agreed" (y/n) nods along "agreed" bella agreed

Thinking the conversation is over bella turns her fat ass around showing a bit to her brother with a wiggle.
