You take the serpent's tail up your ass and the deer dick in your mouth, leaking out buckets of milk.
From Create Your Own Story
Magic has helped you produce dozens of new hybrid children for the creatures of the forest, and to feed them all they need more human milk. As the serpent man writhes his rough tail around inside your ass, you moan and top off another bucket, wondering why they need human milk. The minotaur lets you suckle her tits, rejuvenating your sore holes and protecting them from the prickling scales of the serpent.
It's starting to get dark when the serpent finally stops violating your asshole and puts his dick in your pussy. You thought you were prepared for it, but the stiff fleshy barbs dig into the walls of your vagina, making you howl. You instinctively try to get away, but that's the point of the barbs. As he starts coiling and writhing his body around, the minotaur squeezes as much milk as she can into your mouth. Thin spurts of the white fluid come flying out of your mouth as you desperately breathe through your nose.
Her milk's magical effects turn the pain in your pussy into numbed pleasure, the fleshy barbs only tickling you now as long streams of reptilian semen pump into your body. After hours of violently endless ecstasy, your body loses control. You gasp, taking your mouth off of the minotaur's supple nipple skin to moan for more.
"By the light, harder!" you command the serpent man. You don't care that you don't have the minotaur numbing the pain. The sharp barbs comes back in waves, and you start to cum all over his dick and squirt out ludicrous amounts of milk. It's so much that both the bull and deer centaur have to lift you up and drink up the remaining about while the minotaur gets more bowls.
"Bite me!" you shout at the two centaurs. "Bless these hard working tits for all the life and sustenance they've given!" Your eyes start to glow as magic you've heard about from your paladin training begins to flow through you. You light skin turns tan, then slightly golden while you eyes shine a luminescent light blue.
You turn your head and look the serpent in his eyes. "Don't ever pull out," you tell him, "I can take so much more, give me everything!"
The minotaur returns, and puts the buckets where your breasts can stream their milk into it. Free from sucking on your tits, the two centaurs decide to give their reptile friend a hand. The serpent coils around you and you both lie on top of the deer-centaur and below the bull. After so many hours, the bull's massive cock is finally free to be used to the fullest. He slides it smoothly into your cum-crusted ass, opening some new part of your intestine that hadn't been reached the entire day.
The deer-centaur's dick is longer than the serpent's, and he uses it to pressurize your uterus while the serpent continues ejaculating into you. You don't know where all that fluid is going, but you hope none of it leaves you.
"More, more," you shout. "Go faster, go harder. I thought you were supposed to be animals! Go on, act like it, use me like a piece of fuck-meat. Violate the humanity from my flesh!"
The minotaur decides she needs to join in now to give you what you need. She reveals her tongue's full length, kissing you with it and sliding it all the way through your mouth and down your throat. You can breath through your nose, so you open up your jaw even more and swallow up her tongue. You shake your head around, feeling the tip of her tongue wiggling around your esophagus. You can taste your own milk as not even the new buckets can keep up with how much you're producing.
Filled with brilliant magic, even your muffled screams of agonizing pleasure and unfulfilled desires seem to shake the air. The other creatures fall back after ten or so minutes, exhausted by your ceaseless demands. You own body relaxes as the last of the magic potion changes your body and turns you into an egg producer. Dozens come out in a stream, a little bigger than a chicken's egg. You know there isn't room in you to keep all that, so the magic must be spawning them at an inconceivable rate. You lay there for maybe an hour, giggling and releasing egg after egg, the popping sensation never ceasing to give you a little burst of pleasure. Once the last egg pops out, you think about what to do next.
