(This video is a bit cheaper because it's shot on my phone rather than my filming camera!) You're gaming on your PC when you feel something moving by your legs, and spot your annoying little step-sister crouched under your desk, trying to gain access to your boxers! You ask her what the hell she's doing and she whines and begs for you to just let her suck your cock, she won't bother you and she'll stay quiet so you can keep gaming with your friends! You tell her no and accuse her of being a little slut, but she insists that it's a real medical issue - step-mom took her to see a doctor who says she has an oral fixation, so it's not her fault, she really needs it! You tell her to go find someone else's cock to suck but she reminds you that she can't, she's grounded for exactly that reason - your step-parents caught her sneaking out and sucking random boys' cocks, so now she's not allowed out any more! She begs you to just be a nice step-brother and let her do it, and besides, it's not like you won't enjoy it! You finally give in, reminding her to stay quiet so your friends don't hear her over your mic, and she gleefully thanks you and takes out your cock! She begins happily licking and sucking it as you try to concentrate on gaming, but she struggles to contain her noises of enjoyment and you keep having to remind her to keep it down! After a while you warn her that you need to cum, which makes her mad! She tells you that she's not had nearly enough time sucking your cock yet, and tells you to hold it in! You try to hold off your cum for a few more minutes but then have to tell her that you really can't hold it anymore; if she keeps sucking it, you're gonna cum. Your step-sister is annoyed but you sigh and promise her that you'll be ready to go again after like half an hour's rest, which cheers her up slightly! She sucks you fast until you cum down her throat, then insists that she'll just stay her under the desk playing with your cock until it can cum again!
