Sis has spent all her allowance money and now needs more so she can go to the mall with her friends. Not bothering to knock before she enters her brother's room, she catches him in the middle of masturbating. Claiming he doesn't know what he's doing she offers a helping hand just as any good sister would do. She asks to barrow some of her brothers allowance then gets topless and strokes his cock for him until he cums.
