Tsubame Sorayama the Tengu lay on a mountain ledge, pleasuring hirself. The unfortunate bird yokai felt entitled to a little pleasurable distraction after the past five months. Almost half a year ago, Tsubame had suffered a really nasty crash that had shattered hir right wing beyond repair. Hir clan's healer had no choice but to amputate the ruined limb, leaving poor Tsubame completely flightless.
Unable to do things shi had once taken for granted, Tsubame had begun to put on quite a bit of weight. There was really no point keeping it off, since Tsubame no longer had to worry about staying light enough to fly, and hir reduced physical activity ensured that meals tended to stay on hir. The grounded tengu now weighed 156 pounds, a 29-pound gain for hir original size. Tsubame didn't mind hir new gut, but it was murder to not be able to join hir fellow tengu at work or play. There was no worse feeling for a tengu than to be useless.
Tsubame stroked her shaft, hir flabby belly rubbing cushily against hir arm as shi jerked off. Shi used hir free hand to play with the nipples of hir bulbous breasts. Soon, Tsubame felt hir climax nearing. Shi leaped onto their knees and aimed their dick over the ledge. If Tsubame couldn't fly, than hir seed would. A gooey rope of cum flew out of the tengu's cock, followed by a second and a third. They flew freely through the air... and right into the face of Ōtori, the mountain clan's messenger bird.
Mortified, Tsubame grabbed hir clothes and tried to through them over hir breasts and penis. "I'm sorry, Ōtori-san! I have brought shame on myself and my family! It won't happen again!"
Ōtori regarded Tsubame sternly. "It is good that you are apologetic, Tsubame. See that such carelessness never happens again. You young futanari need to learn maturity; a penis is a gift that should not be used unwisely. I came here to bring you this week's mail." He handed Tsubame the latest issue of Shonen Jump and a stack of advertisements before flying off.
Tsubame decided to leaf through the ads before reading hir manga. Most of the leaflets were nothing interesting, but there was a single one that caught hir eye. It called for new students to sign up for formal sumo training at the famous Kyodainayokai-beya. Tsubame had heard of this heya, located on the fringes of the city of Kyoto. It was a heya just for magicals and run by the great retired kappa sumo Sensei Kyūri. It occurred to Tsubame that shi looked more and more like a sumo each day. If shi could get the training, than shi could find a fulfilling new career wrestling in the Dohyō. Shi would be able to get out of bed with purpose again! Tsubame got dressed and ran to ask hir mother and father about signing up for Kyodainayokai-beya.
