That’s MY toothbrush… and that’s MY cock! [VIP4K]

It started off like any other evening: I was getting ready to spend a few minutes washing up before bed… but my sister got to the restroom first. The girl refused to let me in and became enraged when she discovered I was using her toothbrush. Please give me a break! It’s not like we’re strangers or something. We’ve been exchanging microorganisms since our parents moved in together. “You’re not my REAL brother!” she said. Oh, and if you don’t mind the toothbrush, maybe I should blow you as well?” To say the least, I was surprised, but it would be foolish to say “no” to an unexpected blowjob! My stepsister is also a badass vixen, so my stiff cock answered with a hearty “YES!”
