He had been bored for awhile. The dinner parties his work always threw weren't something he'd come willingly to, still thanks to peer pressure and the idea of possibly getting fired from his work made him always attend.
For the first few hours he wandered around the large room, eating from the buffet the caterers graciously gave to them all. And finally he began to wander out of the room and into the hallway, to find the restroom as well as a place to be alone.
After relieving himself and leaving the restroom, he would find himself outside, wandering until he stopped under a gazebo, far enough away to let out a long sigh. He'd been at the party long enough and was finally ready to head home to take a hot shower and sleep the rest of the night away.

Not far from where the man was, a much larger creature had found his way to freedom. Walking as usual on all fours, careful with his retractable toe claws and making sure he didn't make much noise as he walked around in this strange large world that belonged to the naked animals that walked on two legs. Humans seemed to be all around, not many of his scaled kind.
Still humans being so many meant that they can all survive. After all, humans were prey to his kind. Even with their fire sticks that shot out rocks that hurt or electrocuted him or made him go to sleep against his will.
Being an experiment to them didn't make him like them at all. And if given opinion between a human or some other animal, he'd always pick humans.
But he digresses and also the growling hunger was getting to him again. The cow he ate a day ago was long digested and disposed of and he was once again on the hunt, avoiding the houses but keeping an eye out for any lone humans.
Hearing the sounds of music made him look up, curious at the distant noise; he walked towards it, picking up the scent of many humans. 
Upon arriving and looking at the large manor, he almost frowned. To many humans in there. "Seems I have to search elsewhere" He grumbled to himself in annoyance and was about to turn and leave when he noticed movement outside that caught his dark red eye.
Seems luck was indeed on his side, for there standing outside and very much alone was a human. The urge to charge in for the kill was so tempting, but he forced himself to think it over. There are what ifs playing in his head. The human could have a gun, or somehow could alert others for help.
Luck seemed to be on his side as the human began walking again, further from the manor of his human pack. Still the Indoraptor made himself stay still, hidden in the darkness thanks to his black scales.

He chose to leave the party finally, having stayed long enough and had probably a bit much to drink. Seem walking to the party was smart since he wouldn't have liked to drive here and have to walk home and come back when sobered up.
Walking home also helped clear his head, the cool air soothed his nerves.
Home was quite a few blocks and he had to pass through a park. Still he took to walking. 
Perhaps it was because he was a little drunk that he didn't sense the danger or eyes watching him. He had no idea something was stalking him, not yet attacking.
Making it across the park and to his front door had felt like mere seconds when it was nearly a half an hour. He unlocked the door and made it inside, turning the knob lock so when it closed it'd be locked. Unfortunatly he didn't wait nor look to see that the door didn't close and lock, nor the long talons that stopped the door from locking as he made his way up the stairs to take a shower.
---
The Indoraptor followed the human, hunting him. Keeping a distance away so not to be heard as well as close enough so if the human did happen to turn and try to run he'd not get far.
Passing the same homes were a tad of annoying when he realized he could have just sat in some bushes and waited for his prey. 
The human finally turned onto his house, making it up the porch with some wobbling that didn't help the predator's hunger. He sensed weakness and made the poor human that more singled out.
Seeing the human unlock the door and aim to close it, he was quick to rush up the porch and ignore the slight pain of his talons getting hit with the hard wood of the door, relieved he stopped it and once again didn't get any attention at all. Were all humans this stupid really? His tail moved about behind him as he waited a few minutes until he pushed open the door with his claws and carefully moved his dark form inside, carefully closing the door behind him so not to get suspicion from nosy humans.
Inside was warmer then outside and the human scent filled this room and nearly made his mouth water. Making his way down the hall, hearing the running water of the shower he lowered himself, instead of attacking, he just waiting for the human to enjoy his final hour of thinking he was top of the food chain.
---
Taking a shower was what he needed, it cleared his head some more and unknowingly provided a clean body for something else. 
Once done he walks out of the shower, pulled a towel off it's hanging bar and dried his body off. A contented sigh escaped him and he sat down on his bed. Another night.
He may as well make the most of it. He felt a need and so he turned on his laptop and began to watch his usual erotic clips he had saved.
Arousal would come and he'd begin to stroke himself, breath quickening and moaning out, not knowing at all that something else saw him until he looked at the sudden movement that startled him.
There, standing at the foot of his bed was a.. well, it was a fucking dinosaur! And he screamed out in fear until suddenly the claws lifted the beast up and to add to his horror, he saw something that no man ever saw before. 
It was obviously a male since he had a penis that was as erect as the man's. Oh god!
Was this damn thing aroused at the sight of him?! He whimpered and expected the dinosaur to shred him with the claws and sharp teeth.. but it didn't. It was smelling over his much smaller body.
It began climbing over him to his horrified realization, he knew it was trying to get in position to mate with him. "N-No!" He whimpered.
---
Red eyes watched the human with curiosity as the naked man lay on the bed and began to stroke at his cock. That was a strange sight, didn't he need a mate or something? 
Still the man's cock became erect as the hand stroked over it while moaning.
The new scent of arousal made his own penis began to come out of it's usual sheath. A new need that overcame his hunger came over him.
To mate.
This man was small and the fearful reaction only turned the Indoraptor on more. He trapped the human and they both knew it. 
Walking and climbing onto the bed which creaked under his new weight. He relied on instinct to do what needed to be done. The human whimpering and protests made him only need to mate more.
Guiding his cock to the human's opening was not easy given that the human was smaller than him and different in body. Still once he found the opening, he thrust in. His growl mixed with the human cry of pain as he stretched the human's tight hole around his cock. Pushing in was hard and the human struggled to move away.
His claws pinned around the human while his right palm was placed on the human's shoulder so he couldn't get away or move as he pushed his cock inside, enjoying the tightness that made him moan out in his own pleasure much to the human's dismay.
---
He had never thought he'd have lost his virginity to something that should not have been. 
It stretched him painfully that he thought he was going to be ripped in two from the beast. It pinned him so he couldn't get away nor get some relief. It hurt so much, stretched beyond his limit and the thrusting in and out caused his virgin hole to widen, taking the enormous cock.
It was painful until suddenly he was hit in just the right spot and pleasure began to overcome his agony. A moan escaped him before he could stop it as the beast took him, making him all his. 
The large cock began to feel good much to his shame as the creature seemed to enjoy the still tightness of the human. His cock was showing what his body felt, standing at attention and some precum began to come out of the tip. "Fu-Fuck.." 
The bed could not handle the fucking and the frame broke beneath them, both not noticing and the Indoraptor barely breaking his thrusting into his prey turned mate.
What his co-workers would think if they happened upon this sight only made him more aroused, moaning as the Indoraptor filled him. Showing him he was the dominate one, growling and drooling over his naked body.
He would cum much quicker, white shot upon himself as he slowly lifts his legs or tried to so the dinosaur would have better access. The feeling of something else began to come into him. What felt like a knot of some kind traveled from the large cock and into himself.
The hot cum from the dinosaur came a minute after. Filling him up to the point he could see his own abdomen expand some from all the semen that was released within him, which caused some discomfort. 
The dinosaur pulled it's penis out and he couldn't move, some of the dinosaur's cum leaked out of him. He was used up and in his hazy mind he was sure he'd have to call in sick for the next month if only to rest and not walk again.
---
The Indoraptor took him. Mated with him. His cock had knotted and he released everything inside the human that funnily enough looked a little bloated. "You're mine." He growled out, not the human could understand him.
He was to tired to eat now so instead he just decided to lay down beside his used up mate on the broken bed. A new instinct coming over him for tonight. To protect the other and his future children.

Oviposition Part. To skip, scroll down
He had woken to more discomfort inside of his body. Waking up besides the Indoraptor felt suddenly like the least of his worries as he got out of bed, whimpering with pain as the discomfort became painful.
He cried out as he didn't even make it to the toilet and he feared the worst as something pushed itself out of him. He expected something less worse than what he saw to his horror.
There, on the carpet was a large opal colored egg that was covered in what looked like shiny slime. "Oh fu-fu--!!" He felt more pain and began to feel another push out of him. Another egg would be presented. Finally he gave up trying to get to the rest room as his body forced egg after egg out of him, it hurt a lot and also brought growing relief as he emptied himself and lay there, newfound exhaustion washing over him.
He had laid six eggs in all. Six of the Indoraptor's offspring that would either hatch into more like him or be empty.. only time will tell. He wouldn't get to witness his and the Indoraptor's possible children..
Oviposition End

The Indoraptor had woken up finally after a good sleep on the destroyed bed. He woke at near the same time the tired and sore human woke up. 
Breakfast was served, the feeling of mating was forgotten and hunger took over once again. The need to protect was gone, either due to him realizing there is no possible way the human could carry his babies or just forgetting that he indeed mated.
Either way he licks over the human who tried to push the Indoraptor away. Arm accidentally slipping inside the jaws and the burst of flavor sealed the human's fate as he swallowed the arm, showing the bulge in his throat.
The human struggled then, crying out for help as the Indoraptor moved into position to swallow the human up whole. To him, this was a thank you for the night before. In his mind, swallowing the human whole and alive was better than tearing him up and chewing up the bloody mess.
He loved that the human seemed to want to be eaten, since the remaining arm tried to pull his half swallowed arm out, only for the hybrid to quickly open his jaws again and engulf and swallow the other arm quickly. 
Swallowing down the arms made it all so much easier as he worked his way down the human's body who struggled and cried for him to stop. Engulfing the head muffled his screams and swallowing his head, neck and shoulders down. The screams vibrated under muscle and scales, legs kicking at air and the bed as the Indoraptor took his time eating the human up, savoring his naked form and the bit of saltiness that came from the sweat and last night's fuck.
---
He couldn't believe it. He was quite literally breakfast in bed. Eaten up by the dinosaur. He screamed within that only vibrated the insides. The air was thin and smelled disgusting. He kicked and struggled but felt there was less and less of him outside and more within.
Body was making a noticeable bulge on the Indoraptor's skin as he was eaten alive. The powerful throat muscles pushing him down into the empty belly that growled loudly for him. The lining opening up and pushing him inside the stomach where he began to squeeze inside. "Stop! Please!" He screamed out as he tried to hit the stomach with his fists.
There was one more cruel tease this monster gave. The tongue found his cock and licked over it, the powerful tongue causing arousal to come once again against his will. He couldn't help but moan out again as the tongue teased him, licking him as if it was a final goodbye.
Good things come to an end, and his fear returned as he felt his cock and behind join the rest of his body and slowly his legs followed. And with one final gulp, he disappeared. Becoming only a human shaped bulge that traveled down into the stomach that bulged out more.
---
His jaws that had unhinged like that of a snake, closed and clicked back into place, sealing the delicious human inside. The bulge filled his stomach right up and the wiggling of something alive felt so good.
He lay on the man's old bed, resting himself as he watched with a growing smile at the bulge that was once his mate wiggle desperately as the air ran out. 
Humans were much more enjoyable when alive and kicking inside of his stomach he come to realize thanks to this experience.
---
It would have been three days and no one heard from their friend. The door was locked so no one tried to enter. The Indoraptor slept in the old house, digesting his human meal in peace.
When someone did make it inside the house they'd find no one aside from a broken bed. The Indoraptor was long gone. Finding himself able to move better since the human became less and less human shaped, digestion breaking him down into nourishment for the hybrid to hunt another day.
No one could ever expect a dinosaur would have been the cause for a human's disappearance. Well, until they are half way down his throat of course, but that's a story for another day with another unfortunate little human.
