I walk in on my step-bro jerking off and find the perfect time too tell him that i have a crush on him and want to be more than anything his personal cum-slut. I take off my short skirt and crop top to reveal my black lingerie and begin to suck his cock . Moaning while i do so encouraging him to cum down my throat.He does so, i open my mouth show then swallow ~I come back into his room after parents are away and prove how dedicated i am to being his cumslut. 1st he hands me a collar after getting naked then hands me a marker and demands me to right on myself ! With slut written on my forehead and chest i suck him off to completion , then rubs the cum on my tits and face!
