Helping Sister

I am so tired of doing homework. Can’t we do something else? Anything else would be better than reading these books! I know you like looking at me in ways you are not supposed to. What if I strip out of these clothes and give you a peek at what I have grown into. 

You are getting so hard. I love that! Can I hold your cock in my hand and stroke it? That feels so good and so wrong at the same time. I just love how naughty this is. Come on brother, won’t you cum with me?
