Brother comes in while i'm having my private time in my big diaper. He knows I don't like to be disturbed when I'm lounging in my diaper so I'm pissed and scolding him for disturbing me! But he doesn't care! He's a perv and likes seeing lil sis in a diaper so I decide to fuck with him more! I give him a blow job while wearing my big diaper! The drool drips from my lips, on to his cock, and then drips down to my fluffy diaper! Brother cant resist. I show it off for him, crinkling the soft material and teasing him about how much her likes his lil sis in a diaper! I unstrap my diaper and expose my pussy to big brother! He fucks me hard!! filling my pussy and my diaper up with his cum!
