My big step-sister has been taking care of me while I'm confined to the couch with the flu. I've been wanting to take my mind off things by masturbating, but I'm just too sick. Holli has always been cool with me masturbating in the same room, so I went for it with her approval, but she could tell I was frustrated when I kept sneezing and interrupting myself, so she offered to help! What a loving step-sister.
