Your naughty sister is upset she has to stay in but Mom and Dad said she had to stay home. Here I am dressed in a sexy red dress and very hot stilettos. I tell you, my bro, that I know your secret and threaten to tell Mom and Dad. I have always been curious about your cock since I hear you masturbating. After some convincing, you take it out and stroke it. Soon Sister is disappointed to see how small it is. She shows you on a big dildo what she would do to you if you were big. Suck you, titty fuck you, and she almost showed you what it would be like in her pussy but small dick bros don't deserve to see that. I encourage you to keep stroking that cock though, hoping it will shoot a huge load. Now your naughty sister needs to have fun with this big cock while you just listen
