Jemma "Grab A broom"

Jemma is clearing out the barn and wants you to help her out, she has no idea you have been watching her in her dungarees getting a hard cock over her perky tits! Every time Jemma moves her arms to sweep the barn floor her tits move behind her dungarees, your cock twitches more and more in your trousers. Will she notice if you start rubbing your dick through your trousers? Or will you have to sneak off with the mental image in your head and have a sneaky wank behind one of the barns.
