Summary - A big sister is woken up by her little brother in the middle of the night because he got startled awake from a nightmare. She tries her best to comfort him because she loves and cares for him so much. She has him cuddle really close to her, when she notices that his cock is hard! Although it seems the little brother doesn't notice it. The big sister knows that he's sometimes naive (especially when it comes to anything sexual) and she decides to take advantage of this moment! She convinces him to have sex with her, telling him that it's "totally normal" for a Big Sister to take care of their Little Brother like this!
