Yes, her tits are valuable. You don't want to damage her milk production.

With your significant height difference you can align your dick with her chest if you kneel. Your 12 inch cock lands between her wet breasts with a meaty thud. You scoop up her tits in both hands and carefully press them to either side of dick. Their ample flesh fully engulfs you. You give a testing thrust and savor the slick smoothness.

You lean forward and kiss her deeply. She weeps into your lips. She is genuinely content at her restored place, knowing she serves her Master again. She moans deeper into your mouth as you squeeze her tits tighter around your stiff shaft. Large quantities of milk squirts from her nipples.

You lean back and begin to thrust into her mammaries. She grunts to the slow rhythm of your thrusts. You stare down at her savoring your ownership. Streams of milk escape from her with every motion. Her pouty lips hang open and her grunts turn to a growing growl of need. Her buzzing clit and submission to you have her needing an orgasm.

"Master... ugh... May... ugh.. I... ugh... Pluuuh... ugh... Eezz... ugh.. Cum?"
