Cailin, his step-sister

Cailin, Jango's step-sister, had busted into the bathroom without knocking again so she could use the bathroom. Jango reacted quickly and shut the curtain before yelling at her. "Cailin, knock damn it." He said with anger coming from his voice she just giggled and went to go pee on the toilet almost next to him "Sorry, you know I have a tiny batter, I mean blatter." She said and sat down with a laugh, making Jango a little uncomfortable. He always thought he had a small dick but never wanted to see what the average size was or show it too anybody just in case it would prove him right

In reality though his dick was around 7" long soft, and about 11" hard. But because of years of teasing from his step sister he thought it was small. The only reason she teased him about it was because when they were younger she saw it and thought it was small. Another thing she knew about and teased him on was his crush on her "Does it make you hard, thinking that I'm only a few feet from you, with my pants down and legs open?" She asked and smiled at the silhouette of her nervous half-brother before finishing her business and walking out of the bathroom.
