My adorable sister with braces has been cold all day long. She loves wearing black tights so much that she can't live without them on her body. One day, after giving her various denier levels of black tights, I couldn't help but feel aroused when seeing her wear them. During our rubbing practice (pantyhose), I got too excited and made her cum, causing her to wet herself. Unable to control my desires anymore, I ripped off her tights and gave her a forbidden creampie... ever since then, whenever I stimulate her centerfold pussy, she squirts uncontrollably.
