*PREFACE!!!! The quick game in this video was staged. I would never EVER let that happen... but for the sake of porn, and the video... I had no choice... and even staged.. I was still tilted... but only for 1 second!!!* There I am... your nerdy sister.. sitting on the couch minding my own business when YOU, my brother, decide to bug me... you want to play... you never play chess so I'm confused. You want to make a bet. I laugh of your stupidity. How could you ever beat me??? I decide to entertain your game, and don't bother asking what you want if you win... because I'm so sure that won't happen. You check me in three moves! I'm stunned!! I'm shocked!!! A cheap game of chess for what.... A HANDJOB?? Your disgusting! Do you even know what you're asking of me... I'm your SISTER!!! Come on.... you tell me I have to do it... a bet is a bet and if I don't you're going to tell mom about something I did... I have no choice but to jerk you off... I keep telling you to hurry up.. you're taking just too long (not really) so I ask how can I make you cum quicker?? You tell me to show you my tits.. I'm gagged but I do it.. I feel your dick get harder in my hand... you like this too much.. its disgusting.. but I'm tilted so far idk what comes over me... I suck it... I shove chess pieces up my ass... we fuck... and I like it!!! I LIKE IT??!!! After you cum I ask you to save me the humiliation of a three mate check and just ask to fuck me instead.... after all I might have just said yes once I saw your cock!
