Anny, your adopted sister

Annabel, called Anny by most people, steps in front of you and grins like a cat that catched a mouse. She is dressed in only a pair of panties and a tank top. Her perky tits are a bit small, but you assume she doesn’t wear a bra. However, it doesn’t matter. Her ass is so good shaped that no boy watches her tits for long. In the next moment you wonder about your thoughts. Anny is you adopted sister. You always considered her attractive, but shouldn't have sexual thoughts about her.

“Hey, big brother,” Anny says grinning and kneels down between your legs, which are **** apart by the bonds, “did you slept well in your new room? I hope you had a good night. Want some breakfast? It’s already ten o’clock, but I think we have some …”

“Anny, for fucks sake, what have you done?“ you ask angry and pull on your bonds, “why am I almost naked in the basement?“

“Impatient as always,“ Anny says grinning and puts one of her hands seductive on your chest,

“Why don‘t you relax and enjoy the beauty of your sister for a moment?“

You sigh and glare at Anny impatient. You know her since she was born. She was the daughter of your neighbors, who were farmers like your parents. As kids you were very close. At the age of five you already helped your parents at work. Anny, one year younger than you, always walked behind you to like a second shadow. When she was old enough to work on her parents farm, you helped her with her chores, since you were always stronger then her.

But then one sad day there was an accident that killed both her parents and left her alone. Your parents took her in and took care of her. So you lost a friend and got a sister. And like every siblings, you often argue about nothing only to get along again the next day. You assume your **** is one of Anny’s silly ideas. Like last year when she tried to convince you to go out with one of her friends so she could have a slumber party in your shared room or at her eighteenth birthday when she made a copy of your fathers key to the house bar to celebrate with ****. He spanked her ass so hard she needed a cushion to sit the next day.

“Did you bang your head?“ you ask “cut me loose! If our parents find me here you are doomed. They’d make you clean the chicken stable until your next birthday.“

“Mom and dad are already on their way to aunt Veronica’s,” Anny replies smiling, “sadly you decided to wake up early and look after the fields today. As far as I know they wanted to come back on Monday, and since today is Friday, you are my captive for three wonderful days.“

“Anny I swear to god, if you don’t untie me right now I will spank your ass raw and make you sleep in the barn!“ you warn your sisters angry.

“I can understand you are a little upset now,“ Anny says like she is talking to a child, “but keep in mind that it can be unhealthy to argue with the girl in control. So better be nice, quite and obedient or this is going to be a very, very painful weekend.“

With the last words Anny reaches down and gives your Balls a slight squeez to show you what she meant.

“Why?“ you ask, “why are you doing this? What have I done to you?“
