(This video is a bit cheaper because it's shot on my phone rather than my filming camera!) You and your sister are having to share a room and a bed for a while, and your sister is getting frustrated! She eventually admits to you that she normally masturbates every night before going to bed, so having no privacy is really starting to wear on her! You can definitely sympathise, and you suggest that she just go ahead and do it, and you won't look. Your sister is a bit unsure about this idea, but you insist it will be fine and you'll just look the other way. Your sister pulls out her vibrator and begins shyly masturbating through her pyjama shorts, trying to ignore the fact that her brother is right there. But after a few minutes she catches you looking, and is furious at you for not keeping your word! You apologise and say you tried but it was difficult; it's very distracting having someone do that next to you. You encourage her to keep going, and though you try your hardest not to look, she catches you watching her again. She realises you have a boner and is shocked and grossed out by this, telling you it's wrong to react that way to your sister! She calms down after a moment and admits that she understands that you must be frustrated too, and it was probably just a natural reaction. She notices how big your cock looks in your pyjama pants, and shyly asks to see it.. Once she's seen your cock and how huge and rock solid it is, she decides that it's fine if you want to stroke it too. That way you can both get rid of your frustration and get a good night's rest. You begin jacking your cock as your sister goes back to masturbating, and she can't stop herself from watching you in fascination. She admits that although it feels very wrong and dirty to be doing this, it's hot and exciting too. She strips off completely so that you can have a proper view as she pleasures her pussy, and the two of you keep masturbating until you both cum together!
