You (my brother) and I are trying to have a wholesome sibling movie night, but you have to ruin it being a horny mess! I'm kinda disgusted and frustrated how you can't help it but get hard when you're with me... It's like ever since we started having sex, you can't get enough of your sis... I reluctantly let you fuck me, your cock is so big and you wanna get it so fast inside of me! i hate how good it feels though... how much I squirt and cum on it, how my legs shake in pleasure as i ride you hard and deep! It's so fucked up how much we love it... now you'll have to cum on my mouth brother,give me your sweetest biggest fattest load or else I'll tell your gf about our little secret... oh no, you just made a mess all over me and I wasn't ready! You're so annoying, but I love you only like a sister can
