Violet is reading a book for some revision but you need to book too, she tells you that she will let you have it when she is done. You decide to stick around and notice that she isn't wearing a bra, your cock instantly springs to life and it doesn't take Violet long to realise that you are trying to look down her blouse. She can't concentrate with you perving on her so she agrees to let you wank over her tits if you leave her alone to finish her revision.
