It wasnt in Yuuji's nature to be jealous.
It wasn't.
It really wasn't.
So why did he feel such a burning hot jealously in his little body the moment his Satoru had to leave and go to school? It felt like it would burst out of him from the inside, claw it's way out of him through his throat and exit in a burst of flames that scorched everything he didn't like.
He knew it was just school, he had gone before for a few hours.
He hadn't liked how close his Satoru was with others, didn't like seeing him nuzzle and see his tail wrap around his friends at school. He felt like only he should do that, only his scent should exist on him.
He wanted Satoru all for himself, wanted to cling to him like the child he was and make everyone know that they were eachothers.
His Satoru agreed he was his, but said he had duties to fulfill as the strongest and he couldn't wait by his side for him to be strong enough to join him.
Okay fine, he could admit to himself he actually was jealous. It burned in him, ate him up from the inside out. It was acidic and cold, burning him up with icy heat.
But none of that mattered when Satoru came back from school, smelling slightly of others and strange places.
He could curl up in his Satorus lap, get soft pets and giggled anecdotes about the olders day as he kneaded the soft tail of his beloved. That was the only times the beast in him was soothed, quiet in ways that made him buzz with the absence of heat.
In turn he got his own tail pet and kneaded, soft scratches around his fluffy ears as he purred in his lap.
It was comforting, to be so together and entwined, tails curling in a spiral together and hands warm and nice on one another.
He spent most evenings in Satorus lap, arms around his waist holding him close and purring contently as they watched movies or his Satoru did homework from that horrible school.
Both enjoyed the closeness, the warmth and comfort of the weight in his lap, of the warmth at his back.
It soothed that angry little beast inside of him that wanted to rip Satorus friends apart, to make Satoru rely only on him.
Yuuji knew it was wrong, but he still couldn't help the angry fantasies of having Satoru all to himself and to be his alone forever.
Besides hed have to wait a few more years, continue growing up to be strong and stand beside Satoru. Then he could see about doing something about the burning jealousy in his stoumach.
