You willingly enslave your aunt

"In the pictures, even though you're tied up and in pain there's a smile on your face. Everything you've done, you love this lifestyle don't you?"

She doesn't answer so you give her a spank. She keeps her lips sealed. You spank her over an over again but she refuses to speak. You swear you see her trying to hold back a smile as well. With a final resounding spank she finally speaks.

"YES! I LOVE BEING USED AS A SEX ****! I'm a dirty pervert who gets off to being tied up and used by strong men!" She finally admits. You swear you felt some dampness with that last spank. You unzip her skirt and let it fall to the ground. Her black silk panties are wet with excitement, so wet you felt it through the skirt.

You realize she may have had ulterior motives this whole time. You spank her again, this time her skirt can't protect her bum as you ask "It was you who suggested to mom I come live with you wasn't it?"

"Yes."

"You asked me to clean because you wanted me to find your secret didn't you?" Spank.

"Yes!"

"You did all of this so I'd make you my sex ****!" You yell and bring your hand down in a powerful spank.

"YES!" Your aunt yells out as she orgasms, spraying her juices into her panties and on your hand.

You watch her pant on the table, her breasts heaving with every breath. You never thought the first time you made a girl cum was from spanking them, let alone that woman being a relative. As you look down at her your brain is flooded with ideas. Now that you know she wants to be your **** any hesitancy you felt about this vanishes.

You grab a black leather collar from the pile of restraints and wind it around her neck. You fasten it tight, making sure she will always feel it and remember what it means.

"You belong to me now ****." You tell her as you clip a leash to her collar.

"Yes, Master Mark. Thank you Master." She replies, you can tell she's been trained well.

With a tug on the leash you pull her back up and you pull her in for a deep lustful kiss.
