So I was 16 at the time and my little brother was 11 I was pretty and busty, but also lacking in the upper arms. My little bro, let’s call him Kevin was an early bloomer he was already “5’7 and muscular at the time. Being my 16 year old bitch self I always teased Kevin by bending over in front of him and “accidentally” touching his dick, and bossing him around despite being “5’2 and far weaker than him. He would tolerate it cause he was 11. one day I found him jerking off to step sister porn (this should have been a red flag) and then I thought I should tease him, so I threatened to tell Mom and Dad while bending over to show cleavage. This is when Kevin finally snapped he slapped me and shoved my face against his dick. “Do you like that Lillian? huh you bitch” Kevin said “n-no pls let me go I’m sorry” he then began moving my face up and down his shaft pressing my lips in “smell my fat cock sis.” “Little bro stop pls” he slapped me and I started to cry “shut up you whore you’ve teased me for too long always touching my dick you wanted it didn’t you fucking slut” Kevin said “no no it wasn’t like that I’m sorry” he then started choking me and shoved his cock in my mouth I was crying and he just told me to shut up and take it. He then started deep throating me shoving his cock deep in my throat. After a minute or two he came “swallow it like a good cum dump sister”
