Evil Step-Sister Ruins Little Step-Bros Handjob

Living with my little step-brother has really been getting on my nerves lately. In addition to being gross and annoying, I found out that he's been telling our mom about all the guys I've been meeting online and bringing back to the house to fuck. I'm so sick of him, I honestly think he's just jealous that he isn't the one who gets to fuck me. After getting off the phone with mom and getting called a slut blah blah blah, I decided I needed to get some revenge on him. I told him I would give him a handjob if he would just leave me the hell alone for once, of course, he agreed. What he didn't know was that I had a surprise planned for him, I stopped jerking him off right as he was ready to cum! It was hilarious watching him struggle as his cock shot the cum out without my help, so pathetic. Hooking up with my little step-brother was kinda gross, but it was definitely worth it to see the look on his face at the end lol :)
