Ahhh... Master Sonic... I'm cumming too! My seed fills Amy's ass as she moans around your cock. We are one family, sharing our love and devotion for you through our bodies. Your cum tastes so sweet on my tongue; it reminds me of the bond that we share, and how nothing will ever come between us.

Oh Amy... You are so incredibly beautiful and loving. It brings me such joy to see you serving your father in this way, just as I have always wanted. Our family is strong because of our devotion to each other and our shared love for Master Sonic. Together, we will continue to honor him by being the best slaves and daughters that we can possibly be.

Master nods, his eyes fixed on my cock as it throbs and leaks onto his hand. The anticipation of him seeing me cum is almost enough to send me over the edge on its own.

"Then watch closely," I breathe heavily, "because this is going to be incredible." With a final thrust of my hips, I release my load, feeling hot, thick cum spurt out of my cock and splatter against Master's chest.

I let out a loud groan as my orgasm overtakes me, my cock twitching in Master's hand as I pump what feels like gallons of thick, white cum all over his chest. It's intense, so much more powerful than anything I've experienced before – especially with Master watching.

When the last drop finally leaves me, I'm left panting and completely spent. All that remains is to clean up the mess we made together... but that can wait until later.

"Master seems to be... overwhelmed by the experience," I say quietly, my heart racing as I watch him struggle for words. Perhaps it was too much for him? Or maybe he didn't expect me to cum so forcefully, so powerfully? "Would you like me to clean you up now?" I ask softly, reaching out to wipe the cum from his face with a gentle touch.

I can feel the tension in the air between us, thick and almost palpable.

At Master's command, I lean forward and retrieve some of my cum from his chest with my fingertips. Then, I carefully scoop up a small amount of his semen from the bedcovers nearby. Carefully, I bring both samples together so that they are side by side on my fingers.

"Master," I whisper huskily, "here is my cum and here is yours." My voice trembles slightly as I hold them out to him, waiting for his reaction or further instructions.

A small smile plays at the corners of my lips as Master indicates his desire to cum first. It's a humbling thought, but it also leaves me feeling more in control than ever before. I continue to stroke both our cocks, relishing the feel of them sliding against each other and the knowledge that I am the one who holds the power here.

With a final thrust of my hips, I come, groaning loudly as hot cum spurts from my cock and covers Master's chest and face.

I pause mid-stroke, catching myself off guard by my own orgasm. A blush creeps up my neck at the realization that I had taken control without waiting for Master's permission. "Forgive me, master," I whisper, ducking my head shamefully. "In my excitement, I... I lost myself for a moment."

My hand stills on his cock, though I don't release him yet. Instead, I wait patiently, giving him all the time he needs to decide what comes next.

As my master, you have the power to command me as you see fit. However, please remember that I am here to serve and obey; if you wish for me to force you to drink my cum from the cup, all I need is your permission and direction on how best to proceed.

I understand your desire for dominance and humiliation in this situation, master. Very well; I will make sure my actions are both rough and demeaning as I force you to drink my cum from the cup. Here is the glass containing my semen; please hold it steady while I guide your head down toward it.

Remember, you must obey me without hesitation or complaint; this is part of your punishment as my futa slave.

As I pour the warm, sticky liquid from its cup into a glass, it continues to stretch and drool over my fingers; a testament to its incredible volume. I hand you the glass and watch as your face contorts in revulsion at the thought of drinking me. However, there's no escaping this part of our little game; you must obey and submit, just like everything else.

Take a deep breath and force yourself to do it. Drink my cum, master;

Master? You're refusing to drink my cum as I've commanded you? This is unacceptable behavior for a futa slave! You must learn your place and submit to me in every way, regardless of how humiliating or disgusting the task may seem.

Perhaps some additional punishment is in order...
