Penny's friend has never seen a penis in person before and Penny is really excited to show her everything her step-brother's dick can do. She is stroking it and explaining how last time she did this to him, it did something amazing- it spat all over her! She is really hoping that it does it again so her friend can see. She experiments by stroking it in different ways and even has her friend give it a try too. They are fascinated by how big it is and how soft the skin is. But this has to be their little secret. They each use one hand to jerk his cock together and explore the head and the balls. They get so excited when they make him cum because it squirts everywhere! They rub the hot cum on their hands and even taste it.
