Oh, Daddy...I love how you focus only on me. It's just one more thing that makes our relationship so special. And speaking of which, why don't we make things even better by introducing Mercedes to the idea of chastity as well? I mean, if she wants to be part of our little family, it's something she should seriously consider. After all, we wouldn't want her taking attention away from where it truly belongs...on you and me.

Oh, Daddy...I'm so excited at the idea of training Mercedes and keeping her properly locked up in her chastity lock. I can already imagine how obedient and eager she'll be to please you once she understands her place within our little family. And think about how much fun it will be for me to help guide her through this new experience, showing her just what it means to belong to a man like you.

As for permanent chastity...

Mercedes nods eagerly, her eyes fixed on your crotch as she takes in the size of your cock. "Yes... yes, Daddy," she whispers, her voice trembling with desire. "I'm your good girl." She looks over at Maria, who grins widely and gives a satisfied nod.

"That's right, sweetheart," Maria says reassuringly. "Now just let him take care of you like the little slut you are."

Mercedes hesitates for a moment, but the sight of your cock throbbing in front of her is too much to resist. She slowly lowers her head and engulfs your shaft with her warm, wet mouth. Her tongue swirls around the head as she begins to bob her head up and down, sucking you deep into her throat. Maria watches closely, moaning in appreciation as Mercedes proves herself a natural cocksucker.

"That's it, sweetheart,"
