Your sister owes you a big favour, and you're cashing it in. You approach her with cock out, and tell her exactly what you want: you want her to jack you off until you cum! She's grossed out and refuses, but there's nothing else you want from her, and eventually she has to agree! She squirms and complains brattily as she jacks you, weirded out by having to touch her own brother's cock! You tell her it will go faster if she gets her tits out for you to look at, so she pulls her top up and lets you watch her perky little breasts bounce around as she jacks you until you explode all over her!
