"Finally! What took you so long?" Zara asked frustratedly as she entered the training room. She never had to wait that long for Aritimi to pick her up.
"I had to make a quick change in today's schedule. I just got permission to use a certain monster for today's training session," she replied.
Zara took off her clothes to get ready.
"What kind of monster are you talking about?" she asked.
"No spoilers. You will have to wait until the end," Aritimi winked. An oval-shaped pink portal opened near the duo.
A sticky white liquid began to pour out from the portal.
"This portal reminds me of you on an average day here. I don't know why," Aritimi chuckled as the goo began to form into a shape in front of them. Zara just rolled her eyes.
In the end, the goo creature assumed a human form and looked like a human woman covered in white goo. Or to be more accurate, it looked like Aritimi covered in goo.
"Nice, isn't it? I asked her to take my shape while training with you. She got the details pretty good. I can even see the braids of my hair being copied perfectly," Aritimi examined the creature.
"What is this creature?"
"She is a Semen Golem. Her name is Cumy," Aritimi explained, watching the gooey doppelgΓ€nger wobble slightly in place.
"Ew! That's disgusting!" Zara exclaimed, her nose wrinkling in distaste as she took a step back from the gooey replica of Aritimi. The Semen Golem, Cumy, stared back at her with blank eyes that seemed to shimmer with a mild curiosity.
"Not like you have any choice," Aritimi shrugged, "Lay down on your back and let her fuck you."
Zara did as she was told. She cringed as the cold floor touched her bare back. She then spread her legs open wide.
At the same time, a cock grew out of Cumy's groin.
"Go and goo her, you beautiful beast," Aritimi slapped Cumy's ass. A thin layer of semen stayed on her hand after that but she just licked it off with a chuckle.
Cumy took a wobbly step forward, her newfound phallus bobbing with every movement. She looked down at Zara, who lay there, waiting for her.
"Ready, Cumy?" Aritimi smirked, watching the scene unfold.
With a wet squelch, the Semen Golem lurched forward, her cock bobbing as she approached Zara. In the next moment, she was atop Zara, her makeshift gooey cock pressing against Zara's pussy lips.
The gooey member parted Zara's folds and slid in with ease, filling her with the warm, thick substance. Then it slipped deeper inside of her.
"Fuck!" Zara groaned, gripping the floor as the Semen Golem started to move. Cumy's thrusts grew stronger, the sticky sound of their bodies slapping together echoing in the room. Zara's breasts bounced vigorously with each thrust. The pleasure began to build, despite the weirdness of the situation. The goo was deep inside her, pulsing and stretching her walls as it thickened.
The first orgasm approached quickly. It grew from a distant throb to an intense crescendo. Zara's body tensed, her back arched, and a guttural moan ripped from her throat. She hadn't expected this kind of pleasure from a creature that was a blob of male semen with the shape of Aritimi.
Cumy didn't stop nor slow down her pace and kept pounding. Her movements were mechanical and relentless, like a well-oiled machine designed for a singular purpose: to fuck. The gooey cock filled Zara up, stretching her more and more with each movement. The sensation was bizarre, but the pleasure was undeniable.
The second orgasm arrived relatively quickly as well. Zara's legs quivered and she could feel her toes curling. The pleasure was intense, and she could feel the goo inside her thickening even more. It was as if Cumy was depositing more of herself with every thrust, filling Zara up to the brim.
Zara then noticed something. Cuma seemed to be shrinking. She was indeed depositing her body mass inside Zara's womb with each thrust. She seemed to be a head shorter than she previously was.
"Oh, you noticed it? She's gonna feel you up to the brim and beyond," Aritimi winked wickedly.
Zara was already full, yet Cumy didn't stop and kept pumping more and more of her into Zara.
"Aritimi, what's happening?" Zara managed to gasp out between moans.
"I just told you she's going to fill you up. Her entire body will be inside you once she finishes."
"What? Tell her to stop! She can't fit inside me! I'm already full!" Zara was almost hysterical.
"It will be uncomfortable for you but that's all. Your Flesh Fiend powers will allow you to handle this without any permanent injury or death," Aritimi just shrugged.
Cumy didn't seem to care about Zara's distress. She just kept on thrusting, her sticky member never losing its tempo. Zara's abdomen began bulging.
"Fuck!" Zara screamed, "It's too much!"
Zara's entire womb was stretched taut as Cumy continued to press into her, the gooey substance of the Semen Golem's cock stretching her pussy to its absolute limits. The pleasure had transformed into an intense pressure, one that bordered on pain. Despite her protests, Aritimi's smirk grew wider as she watched her pupil's discomfort.
She looked like a pregnant woman now, her belly distended from the gooey mass of Cumy's body. The pressure was unbearable, but the orgasms continued to roll through her body, one after the other. Each wave of pleasure brought with it a new level of pain as she was stretched even further. And Cumy was only halfway there.
Zara's belly looked like an overinflated beachball, lying on her stomach. The gooey substance of Cumy's cock stretched her pussy so much that it was now a gaping hole, allowing the creature to push her body into Zara's womb with ease. Cumy was now the size of a dwarf.
"You're doing great, Zara," Aritimi encouraged, her eyes glinting with excitement. "Almost there."
A few thrusts later, Cumy was the size of a doll and then with a final thrust, she completely slipped into Zara's gaping hole.
Zara's belly convulsed as Cumy's gooey form settled inside her. The pressure was immense, like she had swallowed a watermelon whole and it was fighting to get back out. She panted heavily, sweat beading on her forehead, as the gooey blob began to move inside her.
The orgasms were still coming.
"Okay, she's inside. Now tell her to leave my body!" Zara yelled.
Zara came again as Cumy kept moving inside her. She was in her human shape once again, lying in a fetal position inside the hunter.
