Chapter 13: Marking Your Property

You're currently sitting in the driver's seat, with Tracy next to you in the passenger seat and Mia on her knees beneath her, eating out her sister. You reach over and grab a handful of Tracy's left tit, squeezing and playing around with it.

"God I love these things."

"Me too sir, thank you so much for my new tits."

About a week beforehand you had taken Tracy to get breast implants. Mia had come along too, and the doctor actually used hers as a guide for how to sculpt Tracy's new and enhanced rack. Mia had stood in front of the doctor the whole way through the operation with her breasts out on display so he could constantly look back and forth to make sure he was making them as identical as possible. Both the twins now had matching D cup tits which were the perfect blend of large, heavy and perky.

"So are the two of you excited?"

"Yes sir, a little nervous too I guess." Tracy lets out between breaths as she starts to really feel the pleasure brought on by Mia's hard work between her legs.

Mia also lets out a soft "Mmmhhmmm" into her sister's pussy, not even taking the time to lift her head from her current task. The three of you were currently on your way to the tattoo parlour where your two sluts would be getting some sexy tattoos. You had chosen what exactly the tattoos would be, leaving it a complete surprise for the girls. The two of them trusted you enough to practically own them as your sex slaves, so letting you decide what tattoos they'd be getting wasn't too much crazier than that.

When you originally sent your plans over to the artist he was quite surprised, especially about the fact they'd be going on two seperate girls. He thought it was some kind of a joke at first but after some explaining, you managed to get him on board.
