This is going to be a tickle fluff scene. And it may go a bit deep. It may seem OOC but c'mon, why not? We never seen Bob being cuddly or go into depth.
Ray held onto Bob's tail as best as he could. Thanks to the spines that sprouted from his tail made good use as hooks to latch on. He kept wagging his tail a bit as if trying to get Ray off. As he was a bit annoyed that Ray jumped on him. Yet he couldn't get that smug smile off his face. "Raiden," Bob growled. "Get off." Ray held on as he knew Bob would never hurt him. Not intentionally.
He couldn't help but laugh. "Bob, I have to wash your tail. And you aren't making this easy you know!" He chuckled. He nearly lost his grip and held on tighter. Bob noticed this and shook his tail again slightly to get Ray off. First off, he didn't like his tail grabbed at. Second, he didn't want Ray to get hurt. Bob noticed some rocks near the bucket Ray placed down to bathe him. Third of all, he wanted to mess with a Ray a bit. In his terms he was a hatchling or a juvenile, when they first met he thought of him as a nuisance. As time went, he started to see him as a dueling partner or a close friend. Now after what they went through, he saw him as a little brother.
A little brother, huh? Bob thought about it more. What do older ones do to their little ones? He had siblings sure. But he wasn't close to any of them. He doubted his dragon siblings accepted him as their kin. Only a mobile punching bag. His beastkin brothers, maybe saw him as a joke. A joke of a brother huh? Yet they do respect him.
Ray however, he respects him sometimes. He asks him for advice or help sometimes. Bob protects him and Ray does the same. Sure they weren't related. But he couldn't help be somehow connected to him. Felt bonded to him. He never really felt any kind of love other than his mother. Bob thought about how they interact. It was mainly during duels or missions. Bob could tell Ray was usually tired as the Choten and his goons would cause problems.
Ray had Allie, Gabe, his mother and grandfather and the masters. But no father until recently. Bob never smelt anyone else but those around him. No scent of a brother or sister. So he assumed he was an only child.
Lucky, he thought before. But as he thought about it. Who else could he go to other than his friends when he had an issue that his mother or grandfather can handle. Especially Kaijudo practice. He was certain his friends had lives themselves.
"Bob! C'mon, stop waving your tail!" Ray shouted pulling Bob out of his thoughts. Ray was hauled over his tail and held on as best as he could. Bob gave him a smug smile. Ray pouted playfully and said "Its not funny." Bob gave his tail a slight shake and made Ray squeaked a bit as he nearly lost his grip. Bob maneuvered his tail away from the rocks and towards the sand with little to no debris.
The sudden motion caused Ray to slip a bit. Causing him to yelp and laugh nervously. "Ray get off my tail. There is no Tarborg muck on it. Also I think you got most of it." Ray didn't let go. "Ray," Bob said warning tone. Ray just gave him a smile as if he was enjoying this game.
What did older ones do to little ones? Bob recalled memories of his half siblings fighting. Or "play fighting". They were usually rough and would seem way too rough for a human. Especially for Ray's size. Bob did recall seeing how gentle most humans were. He even recalls how gentle a dog was to a child during one of the missions the masters were one. The child was crying and the dog nuzzled and licked the child making them laugh and giggle.
Would that work? Do older ones do that to little ones? Minus the licking. He noticed Ray was losing his grip and decided to test it. Also, it may or may not be a little payback.
He moved his tail again and Ray fell on the sand laughing a bit and groaned how that hurt. Bob then put his head down and started to nuzzle Ray's stomach as gently as he could. Ray started to laugh and tried his best to push Bob away but to no avail. He couldn't move as much as he couldn't stop laughing. "Baaahahahahhahaahaoooaahoob! Staahahhaaaaahhahappp!"
Bob knew he had to let Ray up eventually to breathe. But for now, he wanted to teach his "little brother" a lesson about grabbing his tail. And don't pet him without permission next time. Little brother? He might like the idea of that.
"Boooaahahahhahaabaahahabaababaoooaab! Nooohahaaanoooo!" Bob then started to nip Ray's stomach as gently as he could. His canines were sharp and he had to be careful. Yet it made the sensation much worse for Ray.
Ray couldn't believe what was happening to him right now. He was getting nuzzled and nipped at as if Bob was tickling him. Bob tickling him? Oh lord that thought was a ridiculous thought!
He kept pushing at Bob's head or his horns to get him off but none of it worked. He was losing his strength due to laughter and there was no way he can push Bob off of him. It was almost as if Bob was playing with him like an older brother would mess with their little brother. Older brother? Bob as a older brother? Ray couldn't think much on it as he still kept trying to get away from Bob's "tickle" attack.
