Sara is a 30 year old sergal taur, an attractive and well-built taur, but unlike most taurs she had more than one lower half, taurs like her are often called taur trains and tier sections are nicknamed 'cars' Sara had 3 sections, the taur train breed is a rare genetic abnormality that doesn’t seem to negatively affect the taur in question, in fact most taur trains have multiple internal organs, hearts, lungs, stomachs, though for females they always have one womb spanning the length of their lower body.  She also has the coloration of a bangle tiger thanks to her father who was a tiger taur.
Sara is a scientist who is a well-known for her biology smarts, she often going all over the galaxy studying all manner of life from plants to animals, and often studies their mating habits 'up close' ;3 but today’s mission would prove to be an interesting one at that.
She was on her way to a forest planet called rizome 3, well known for their friendly animals and colorful plant life, she finds a landing spot and came in to park, getting out she took a deep breath and smelled that fresh untainted air, loving planets like this. She headed out with her equipment to start studying the plant life and hoped to run into some interesting animals along the way, not knowing she was being fallowed.
The ones fallowing her kept their distance till they were sure she didn’t notice them, the taking samples from the local plants and studied some of the more active ones, they being similar to fly traps on earth, only eating things as big as a cow, she kept her distance from these as she watched one with vines grab a two legged t-rex like creature and pulled it into the center bulb, the vines going down its throat and into its nose, clear bulges in its throat as it was being eaten alive from the inside out. The nose it made slowly faded as it dies. She then went on her way. 
She was watching some 6 legged dog like creatures breeding and saw the male had 3 penis's and the female 3 sex openings, as she watched she couldn’t help but grow wet at the show. Her stalkers snuck up behind her and slowly got closer to her, she too busy pawing at her sex from this little show to notice them. When she least expected it they made their move and pinned her down, she yelling and struggling but then got stung in the back of her first section and was knocked out, then the creatures dragged her off to their hive nearby.
By the time she woke up she found herself in the middle of a xenomorph hive, she glued to the wall and stripped of all her clothing and put in such a way that she would have her sex exposed for anyone to see. She pulled at her restraints then heard a deep hiss come from above her, she saw a xenomorph drone eyeing her and baring its teeth at her, then crawled down her front and along her three bellies, she watched and saw this drone was not a normal one, it had a large member and a huge egg sack instead of a tail, not a queen but a new breed of xenomorph, the sack behaved like a tail but was translucent green and had black ribs for support every foot or so.
It got to her last section and used its long fingers to feel around inside her sex, making her let out a forced murr of pleasure. It found her size pleasing and got in place and grinds its huge hulking meat at her sex causing her to let out a deep murr, the size of its member was a little over 4 feet long and about a foot thick, covered in ribs and a glowing green head. She saw glowing green veins all over its length throbbing clearly with its heartbeat as it lined up the tip to her tight sex. 
She whimpered as she knew exactly what it was going to do to her. She struggled but gasped as it plunged its thick meat into her sex, going past her cervix in one go, making her yelp in discomfort.
The drone then started fucking her as its egg sack filled with xenomorph larva, they being semi formed and very active, slowly one by one small semi formed larva filled the sack and caused bulges to push out all over the surface, she watching the creatures swimming and squirming in it, which seemed to cause the drone pleasure from the deep growling it was making. It soon was filled with over 4000 of the little buggers, it knowing her body could hold many young at once, its sack as big as she was and filled to the brim with active squirming larva. 
She squirmed and moaned as she was fucked by the drone, unable to not enjoy it. After several minutes of bring fucked by this new breed of xeno she finally came and it screeches as it reached climax as well, she feeling his member bulge as the larval xenomorphs get pumped into her huge womb, several at a time her womb gets filled, all 15 feet of it till it showed clear bulges in all three of her sections. The drone kept its dick inside her as it pumped in the slime that the larva were swimming inside of to keep them safe and fed. She pants heavily and looked at her swollen bellies, the drone stayed where he was and kept her plugged up, she was so tired she passed out.
