My step-bro is so lazy! He's supposed to be doing my homework but he's just sitting around on the couch! His life must really suck being in chastity and all. He'd probably be masturbating right now if not for step-mom's awesome idea to lock his penis up. Since he has nothing better to do, I am going to make him sniff my farts. My boyfriend can do my homework instead, he's less likely to fuck it up anyway. I release bubbly farts through my shiny leggings making my lil step-bro gag and cough under my full weight on the couch bench. I gleefully bounce up and down and giggle while ripping ass on the suffering boy. Then, I decide to take off my leggings and bury his face deep into my nude ass crack. Stuffed in there, all the sweat and farts sputter right on his face and in his mouth. I kick my legs up and sit full weight. His body is completely trapped, at the mercy of my massive ass cheeks. Wet farts keep coming until I feel like I have to use the bathroom. I'm going to make my step-bro eat my waste too. I make him crawl away to the toilet to wait for me. That's what he gets for being a stupid lazy pig!!
