Ruby laid in the middle of a field, surrounded by the ashes of destroyed Grimm. She was exhausted, and could hardly move. Thousand of Lancers she had destroyed, this hive's Queen Lancer among them. She breathed heavily, her chest rising and falling dramatically.
"That... was... intense...," breathed Ruby.
As she laid there, she heard a slight buzzing sound. She struggled to look up, and saw a single Grimm Lancer still flying around. It noticed Ruby, and it knew that it's queen was dead. It's primal instincts took complete control as it started buzzing its way towards Ruby.
"Stay... stay away," called Ruby, trying to back away from the Lancer.
The Lancer could smell that she was female, and hovered over her, before pinning her to the ground. It stood over her, as though it was scanning her. After a few moments, the Lancer raised a claw to strike, but rather than go straight for the heart or the throat, it simply put a slight cut on her shoulder. Ruby whimpered from the cut, and again when a second small nick hit her thigh. The Lancer knew she was female, but needed to use biological sensors in its claws to determine compatibility, and it found that not only was Ruby compatible but that the chance of her being impregnated was almost 99.9% guaranteed. The Lancer took to the air just barely above Ruby and picked her up.
"Let me go!" Shouted Ruby.
The Lancer took to the sky, flying back to its nest, where it's hive once called home. It used its claws to precisely cut away Ruby's clothing, leaving no non living material on her, and by time they reached the nest, she was completely naked. It dropped Ruby facedown on the floor of the nest, landing just a few feet away from her. As Little Red got on her hands and knees trying to get a fix for where she was, a long, thick and transparent tube extended from the Lancer's thorax. The Grimm walked over to Ruby as the girl turned and saw its member ready for action.
"No... no please don't!" Pleaded Ruby.
The Lancer pressed its member right up against her folds, applying pressure slowly. Ruby tried to crawl away but the Lancer had pushed the head of its length in just before she could. Ruby stifled a moan as the Grimm pressed more and more of its penis into her slit. As the head reached the entrance to her womb, Ruby was breathing heavy, and looked behind her, seeing that the Lancer wasn't even fully inside her. Out of all 18 inches the Lancer had, only about half was inside her now wet cunt. Ruby thought that it was done with entering her but was soon proven wrong as the head of the transparent member started pushing harder against her womb.
"Wait... no, stop! What are you..." uttered Ruby.
The Grimm cock pressed all the way through, hitting the back of her womb and bulging her stomach slightly. Even after that, only ten inches were inside her vagina, but luckily the Lancer stopped trying to force more of itself inside her. She breathed heavily in pain and unwanted pleasure, until her eyes grew wider when the Lancer not only began to thrust in and out of her, but its member also began to lightly vibrate. Ruby involuntarily Moaned as the Grimm gave her folds no mercy. She hated the pleasure she was feeling, but it was so overpowering that it masked her hate. The Grimm thrusted hard and fast, and easily seeing as Ruby was a sopping wet mess at this point. Ruby felt something building up in her core as the Grimm continued pounding her. She screamed out in pleasure as she came, and when this happened, the Lancer could smell through her pheromones that she was ovulating. The Grimm used the side of its claws to spin Ruby around, and then pinned her body against the nest wall as it started to thrust faster and faster. Ruby tried to kick the Lancer away but with her aura gone it was like a fly trying to push a mountain. The member inside Ruby began to vibrate at a higher frequency, causing her to moan almost nonstop with each shaking thrust. The Grimm thrusted as fast as it possibly could and Ruby could see inside its member, and was horrified by the bugling mass of cum growing in the length that was currently laying claim to her pussy.
"No! No please don't! Let me go!" Struggled Ruby.
Her pleas fell on deaf ears and a moment too late, as the Lancer gave one more hard thrust, its seed flowing into Ruby's womb. It's member continued to vibrate, and Ruby screamed out in unwanted pleasure as she came again from the hot seed being pumped into her womb. The Lancer held its member in her, continuing to ejaculate with a seemingly endless supply of semen. Ruby's stomach bulged further as the Lancer's cum filled her womb completely, and then continued to do so, causing it to leak out of her throbbing pussy.
"There's... so much cum..." thought Ruby.
The sensors in the tip of its member, and the pheromones it could smell off of Ruby told the Lancer all it needed to know. It finished ejaculating, and its member retracted from Ruby's semen-filled vagina as the Lancer flew off to its spot in the nest, but not before injecting its temporarily paralyzing venom into Ruby to keep her from leaving. The pheromones the Lancer could smell told it that it's assumptions were proven correct, and that the 100% compatible Ruby Rose was now impregnated by Grimm semen.
