Ra'atok just was wondering along, when a sudden snowfall started, but on his way back home, another, more temperature sensitive creature, crossed his path. Sporting a huge squirming middle and shivering, the snake horse trotted over, his belly swaying too and fro, before eyeing up the kobold before him. Feeling like he wanted something, Ra'atok only managed to open his mouth to ask, some hot breath steaming the air, before the snake horse's head lunged forward... and into the shocked kobolds maw, in a flash, Poor Ra'atok felt the powerful legs of the snake horse propel his fore legs and torso in, muffledly merping about his mawfull of reptile, before yelping in bashful pleasure as he felt his eager prey slithering deeper, tugging in that belly, and parting his jaws wide.
Gulping without thinking, Ra'atok hardly had to do much, before those wide hips slipped in, and the long tail snaked its way between his lips. Moaning from the over stimulation, as his belly ballooned outward, splaying his legs under its girth. The pleasure only making the kobold shelter the oppertunistic prey had dived into, all the warmer~ pulling himself in fully to knead and stretch about to get cozy.... leaving the over stuffed kobold still trying to process what had just happened, and how to get home....

A fun commision done by  FluffyLatios that might be a running gag of similar instances of Ra'atok being filled with snake horse shenanigans
