As Jenny watched Randal have sex with Melody she began to feel a strange wetness seeping down the back of her shirt. Startled she looked behind her and saw that she had knocked a bottle over that was sitting on the shelf behind her.
Carefully she picked up the bottle and read the label. With a gasp she realized that the bottle contained the Formula that had turned Melody into the satyress she had become. Before she could figure out what to do the door to the closet was jerked open and Randal stood there.
With an odd smile he whispered, "My, my, what have we here?"
"W-w-what is that formula going to do to me?" she stammered
"Nothing, you dont change just by having it spilt on you!" he stared at her a minute then got a thoughtful look on his face. "Since your here anyway, I would like your opinion on something, will you do me a favor before you go upstairs?" he asked her with a look on his face that didn't invite refusal.
Scared about what he might do to her she replied "S-s-sure what can I do for you?"
He took her arm and lead her over to where Melody was still moaning with pleasure and chanting the word sex over and over.
"What I need is a second opinion" he said as he lifted one of Melody's breasts with one hand. "Drink some of her milk and tell me what it tastes like to you."
With a shocked look she just stared at him.
"Oh come now, it wont hurt you. See look..." and he bent down and began to suckle on Melody's tit, as he did so Melody began to squirm more and moan louder. "see, she even likes it" he said as he wiped his mouth. "Its perfectly safe, just tell me your opinion."
Unable to think of a way to refuse him she slowly bent down and sucked a little milk out of Melody's breast. It was the most wonderful tasting milk she had ever had. She began sucking in earnest and gulping it down. She noticed a slight tingling sensation but ignored it in the pleasure of drinking that sweet milk.
After what seemed like an hour she finally felt like she had drank her full and stopped. Stepping back she wobbled a little suddenly noticing that her feet were different. With a started scream looked her self over. She now looked alot like Melody, she was covered in a light brown hair and lifting her shirt she saw her now much larger breasts with tipped with large black nipples and she could feel how full they were. Feeling her scalp she felt 2 small horns poking up and felt her large goat like ears. With a gasp she reached into her pants and touched her jet black sex feeling how much larger and more sensitive it was.
Starting to cry she looked up at Randal and said "You told me it was perfectly safe and that your Formula didnt work just by spilling on me!"
With a satisfied smile he replied, "It is perfectly safe and it doesnt work just by spilling on you!" He laughed "You see, you have to have a sample of the animal your going to be come as well as the formula. Getting it on you was only step one. When you drank the milk it interacted with the Formula in your system to make you into a satyress. I like what Melody has become so much it seemed a shame to give her up, but now that I have you... well, YOU can be MY satyress, satisfying my every need." with an evil laugh he ripped her clothes off and pushed her down on the floor.
"Nooooooooo! Please no!" she screamed but felt suddenly very weak from her transformation.
"Ooh Yes, my sweet!" he said as he pushed his very hard penis into her slippery folds. She could feel as it traveled down her tunnel deep inside her. She tried to struggle as she felt it touch the entrance to her womb.
Her eyes went wide as he began sliding in and out of her. Slowly the pleasure was building up greater and greater. As he picked up speed with his thrusts he reached down and began to suck on her overfull breasts. As she felt the milk streaming into his mouth the pleasure hit a peak and she screamed into the biggest orgasm of her life. Again and again he plunged in and out of her bringing her to climax over and over. Just as she thought she couldn't take anymore she felt him reach his own climax and shoot her womb full of his seed, pushing her into an even bigger climax of her own.
When she came to she was strapped down to the table Melody had been on. Looking around she saw that Melody was in a cage not too far away.
"The master should be back soon" Melody said
"What? The master...?" Slowly what had happened came back to her and she looked down hoping it had been a nightmare, but to her dismay she saw she was still a satyress.
Watching her reaction Medoly smiled "Dont worry, you like I did, will see that this is the best life, and Serving a Master is all you want to do!"
"No... I need to get out of here..." Jenny started to say but as she said it she began to feel tingly inside. As she tried to figure out the new sensations her sex began to feel warm and all she could think about was Randal sliding his penis inside it. The more she thought about it the more worked up she became until her sex was dripping with slippery fluid.
Right at that moment Randal walked in. Seeing how worked up she was becoming, he smiled "Are you ready for me?" he asked
"Y-y-yes...." Jenny moaned
"are you ready to become Pregnant with my children?" he asked smiling bigger
Unable to think of anything but him plunging into get deeper and deeper she screamed "YES MASTER!"
With a smile he took his clothes off and walked over to her.
"If we do this you are mine forever. Are you sure?" he asked knowing that she couldn't stop now
"Please master! Take me now! Give me your children!"
With a slow thrust he penetrated her wet folds again and she screamed in pleasure. Looking over at Melody he smiled then began to drink from Jenny's breasts as he shot his seed deep inside her again and again.
