Teens these days have more hormones than they will ever know what to do with. Amy is the perfect example of this. She creeps up on her bro after his shower.
Not to ask him a question or possibly to brush her teeth, but for the sole purpose of seeing his dick. Mom is in the other room, but Amy really does not give a shit. She gargles on big bros cock until he cums, then goes back about her business like nothing even happened.
The next day, she walks in on her bro reading the newspaper in the living room. The first thing that comes out of he mouth is that mom left. We can already kinda figure out where this is headed.
Amy is all about siblings taking advantage of their alone time, so she drops her neck down and gives big bro the BJ of a lifetime. It was way more interesting than anything in the newspaper for sure! Then the tables get turned.
Big bro goes in to ask Amy a question, and he catches her fucking her pussy with a huge pink dildo! He gets nervous and offers to walk away, but Amy Invites him to play along. She shows him how to thrust it, but it just is not cutting it.
Amy thinks he could do a better job, so big bro unwillingly starts fucking her doggy right there in her room. Amy knows how to work her tight teen pussy on her bros cock just right.
Finally, she gets exactly what she has been craving, a huge dollop of bros cock snot. A happy sister is a happy life.
