I've just been a spoiled brat lately and I feel like I owe you an apology. You have been doing me all sorts of favors recently and I have an idea for what I can do to make it up to you. I noticed you looking at me at the mall today while I was trying on clothes with my friends, especially when I put on that really tight sweater so maybe I could model it for you so you can stare at me all you want without having to sneak peeks. I don't mind that you're always looking at me. I know that all guys find me so attractive so why should my little step-brother be any different? At least you're sweet about it and I find it cute that you practically worship your big step-sister! I'll even let you try touching me so you can feel your big sisters tits, I know they must be better than the other girls in your class. Things quickly got a bit carried away and I notice that we've both started getting really turned on by this. I don't want you to be embarrassed or just leave my little step-brother like that but I'm not really sure what to do... But maybe if you love me in that sweater so much maybe I can use the sweater to help you out. That should be okay right? It's not like I'll be naked or anything. After all, I think you deserve to have a bit of fun with your big step-sister after how i've treated you lately. So come over here, unzip your pants and stick that hard cock between your sisters tits and fuck me til you cum all over this brand new sweater!
