I saw you watching me in the shower the other day, Big Step-Brother... I know you touched yourself while you watched me soap up my chubby body. I start with a little innocent boob tease but that quickly escalates into much more. I show you my ass, even stripping off my panties but you want more. So I decide to touch myself right in front of you, trying to see how big I can make the bulge in your pants. I tell you to take it out and stroke for me. But once I cum I realize you haven't yet. Oh no! So I give you the best blowjob you've ever had, gagging and drooling all over your thick cock.
