You nod as you say, “Yes”
“I’ll be right back.” She says as she hops to a door and walks into another room. After a minute or two, the woman comes back into the room with a vholf following her. “Here’s Garval, my favorite vholf to have fun with!”
The woman takes a deep breath as she starts to undress. She’s cute and not much older than you, maybe late twenties. She has sizeable breasts and a nice hourglass form to her body. Her blue eyes meet your misty ones as she flicks back some stray blond, shoulder length, hair behind her ear.
“Here I go!” the professor says as she gets onto her hands and knees and presents herself to Garval. As if on command, Garval moves behind the woman and mounts her expertly.
Lifting her head, the woman closes her eyes and gasps as Garval thrusts into her with a powerful push. Exhaling she presses a button on the device and a light seems to encase them. They seem to lose their colors, blending together, almost into a putty-like form as they begin their fusion.
Garval’s forelegs melt into the woman, following her own arms as they seem to grow thinner, the same strange motion happens with her legs, which shrink in length too. As Garval thrusts again, the movement doesn’t stop as his back merges with hers, leaving her with a wide, canine butt with a tail coming from the top. Looking down toward her groin you also see an excited barbed penis emerge and attached to her stomach in a sheath. As Garval’s chest meets the professor’s back, they start to merge as well and his head seems to flow to the woman’s raised hear and encompasses hers. Her human head shrinks some while Garval’s ears poke from her head. The light intensifies as their form shrinks to about the size Garval was as any stray defects from the putty-form seems to smooth out.
The light starts to dim as grey fur grows from the fused form and details like a wet black nose, claws on the forms paws appear, and the fluffy vholf tail starts to wag, the woman lowers her head and gives it a shake.
The whole process took maybe a minute and you can only watch on as where there were two forms, there’s just one. A fully fused vholf!
“This way also isn’t as fun.” The woman, now male vholf, says from his muzzle in a deep gruff voice. “In the wider world this is how most fusions happen. As you fight, if you so choose, you can further fuse with other monsters too. In your case, with the collar, your base form is a fäks. So when you regress, you’ll become a fäks until you remove the collar.”
“Interesting…” you say as you consider what she said, “Wait my base form? Does that mean-“
“You’re an actual monster.”
“Can others merge with me then?”
“Only if you consent to the fusion while you’re in the act.” He says with reassurance in his voice. “We could merge if you’re so inclined.”
It was all so much to take in! What else didn’t you know? Before you could think more on it, a scent hits your nose. A heat starts to build up in your freshly made vagina.
“Enough of this my mate”, the vholf says with determination. “Turn around so we can start!”
He seems to loom over you as you look at his green eyes. Timidity fills you as you feel foreign instincts start to fire in your mind. Without thinking you ask weakly, “what’s your name?”
With a snort he responds with force, “You can call me Garval! Now turn!”
Turning quickly, you fall back to your new mind’s knowledge and move your tail aside as you fall to your hands and raise your butt, moving it around to help your arousal to fill your mate’s nose.
With a huff of pleasure from Garval, you feel a weight land on your back as he mounts you. Breathing in you steady yourself as your heart starts to beat faster. The room grows still and silent as you wait. Garval’s breathing fills your ears.
The fur on your butt starts to move. His penis you realize! The tip is scanning the area for its target, your vagina. He’s so close, getting closer, and then he finds it. He holds for what seems like an eternity as you ready yourself.
“Let’s begin!” He yells as he thrusts into you!
A pain fills your backside as your vagina is forced open as his penis tears into you! Your vision goes hazy in the pain as a cute “yip” comes from your muzzle. His hard barbed shaft stimulating every inch of your vaginal walls until his momentum is stopped from your tightness. Pulling back greets you with a seeming suction within you that’s pulling to keep his penis within you. A want, no need, to be filled with his seed invades your mind.
Reasserting yourself over the instincts, you know he’s not done though; you keep yourself tight, making it difficult for him to vacate your needing hole. As his removal stops, you take a deep breath and try to relax as another thrust pushes you forward, pain filling your mind again.
A sharp sting at the back of your neck alerts you to Garval’s next action, to hold you in place he’s bitten the scruff on the back of your neck! A wave of relaxation and bliss fills the new parts of your mind as you let him assert his dominance over you. Wanting to bask in the euphoria you let the new part of your mind take over.
Again and again, Garval pushes deeper and deeper into you with each thrust. Pain and bliss mix within your minds as you feel your insides prepare for the prize. You can feel the impulse of battle, to not cum, fight back from your current desires to greet Garval’s cum with your own as you know it’s safe.
Again and again, Garval thrust, rocking your body with his rhythmic thrusts until you can feel his penis grow more massive, straining painfully into your already stretched body. With a final heave his tip rams into your cervix as you feel a warmth fill you from the inside as you let out a loud “Yip!” with a release of your own as bliss fills your mind. Your body goes limp from the emotional release as Garval thrusts again filling you with more of his cum as he collapses on top of you as his penis keeps the two of you locked together.
Content with the warmth within you, with the weight on top of you, and with the security of knowing you’re knotted together your eyes close as your consciousness slips into sleep.
