Stiefschwester weiß, dass ich eine masturbationssüchtige bin. Tabu-handjobs

Stepsister catches her stepbrother with naked pictures of him on his phone, and proceeds to jack him off as she humiliates him for being a pervert! My sis grabbed hold of my semi-wood and started tossing it against my leg and giggling. I'm not sure if I want her to be in control of my cock right now but I have no choice. Her grip is tight and with hardly any lube it is almost irritating me instead of arousing me as her pics did. I just want this to be over as soon as possible. She pulls, tugs, yanks, and cranks in every way possible until she commands me to cum so she can take an incriminating pic of my jizz all over her. She's going to show what few friends I have my pussy load as she calls it. Just when I thought I couldn't sink any lower on the popularity ship, my stepsister has to assert her bratty self and destroy any shred of dignity I had. Now that I am free of that pathetic cum load I guess I will slink back to my room and resume my search of average girls
