Our story has 5 sexy characters:

Raveth - A halfblood Gracile-Robust, who has been raised as a Gracile. He has tan scales, brown feathers, and can fly (just barely). Raveth is as big as the biggest Gracile so he is often employed as a bodyguard by Gracile trading parties, who are always nervous about the possibility of being attacked by a mob of Robusts seeking **** for previous rapes or just lashing out because they are afraid. Raveth has grown up being ill-treated and insulted because he is a halfblood, and out of habit and lack of self-esteem he lets the other Graciles continue treating him badly even though he's bigger than them all now. The only thing that will make Raveth fight is if someone insults his adored younger half-brother, Lyalion. Raveth is a 22 year-old virgin; besides the fact that as a halfblood most Graciles don't find him attractive, Raveth is secretly incestuously in love with Lyalion, and so has little interest in sleeping in anyone else. He has no plans to tell his brother about his feelings because he doesn't want to 'stain his pure little brother with his perversion'. Also as the child of a **** Raveth has always been hesitant about trying to impose his own sexuality on someone else.

Lyalion - Lyalion is the perfect Gracile. Athletic, lithe, and graceful, he is a beautiful flier and the celebrated captain of the local aerial rugby team. Raveth is his hero - the other Graciles may see Raveth as just a misbegotten halfblood, but Lyalion sees only the strong caring big brother who soothed his childhood tears, healed his cuts and scrapes, was always happy to help Lyalion practice sports even though Lyalion taunted him sometimes by flying rings around him, and was always there when Lyalion needed him. As Lyalion grew into an attractive and popular teenage dragon he was disconcerted to realize that the brother who had helped him grow up never got any help from anyone - in point of fact everyone seemed to go out of their way to make his life harder - a life that seemed terribly lonely to Lyalion, who was courted by half the unmated dragons in town and got all the tail he wanted. So Lyalion wants to think of a plan to make his big brother happy.

Kiian - A tiny delicate Gracile with peculiar black patches on his skin, like a pinto horse. He is generally regarded as a freak and abused by the other Graciles. The opposite of Raveth, Kiian has reacted by becoming bitter and angry, a master of the cutting insult. The only advantage of his small size is that he is quick and agile at escaping from his tormentors. He lives in the woods away from the main Gracile town, and so mostly avoids being harassed.

Den - An 18 year old shy submissive red-feathered Robust who tries hard to be normal, but has a secret burning desire to fuck a pregnant dragon, become pregnant himself, or both. He is a soldier, and soldiers are forbidden to get pregnant because that would make them useless as fighters. Den needs his pay and won't break his vow of celibacy, but alone in his nest at night he fantasizes of being **** to become pregnant by a Gracile, or perhaps a big Robust. Friends and fuckbuddies with Mairr, for whom he feels great respect verging on a hero-worship puppy crush. But Den is not truly strongly attracted to anyone who isn't pregnant, and Den isn't Mairr's type either.

Mairr - A HUGE yellow-feathered Robust craftsman and artist. Graciles and Robusts alike tend to be scared of him at first glance, which upsets him because he's a kind, friendly, and playful dragon. He likes to play knight in shining armor protecting those who are weaker or less assertive than him, and acts as an adoptive big brother to his younger friend Den. Mairr loves sex and has a few fuckbuddies including Den, but feels lonely and unfulfilled because he doesn't have a real lover and at 26 his biological clock is going off and he's nervously starting to wish for the pitter-patter of little claws despite his fear of commitment. Because of that fear, what he craves in a lover is possessiveness, someone who will beg/**** him to commit to them - that's why he finds Den's loyalty very appealing even though Den is not aggressive enough for his taste.
