Sonitails: lewd research
RepostI imagine that Tails is someone who would do copious amounts of research into something he's interested in. So when he begins to realize his feelings for Sonic he starts researching all sorts of things about hedgehogs.
It starts innocently enough, things like "[how often do] hedgehog(s) [enter] interspecies relationships", "how do hedgehogs show affection/how to show affection to hedgehogs", "how to court hedgehog". It starts to become more intimate; "where do hedgehogs like being pet", "do hedgehogs like ear nibbling/having their ears nibbled", "do hedgehogs like social grooming/being bathed".
Then after searching for if they like having their backs scrubbed, he comes across something that tells him rustling their back quills makes them feel excited. Learning this info awakens something in Tails. Maybe he's not quite aware of it at first. But his searching becomes more suggestive; "how to rustle hedgehog quills", "what does aroused hedgehog look/smell like" "what smells do hedgehogs like", "do hedgehogs like the smell of foxes", "what do hedgehogs find attractive".
And it becomes more unhinged; he's looking up their errogenous zones, their mating habits, rituals... aaand eventually comes across a video. A pretty simple video, two hedgehogs meeting each other, nuzzling, kissing, then one turns the other around, begins rubbing their back. Then the bits come out.
Tails tries to look away at first, but he can't help but be intrigued by the noises they're making. Chirps and grunts mixed in with gasps and moans. Looking again, he takes in more details, particularly those of the cock; the color, the length, the tip. (So different from his...) Once the video ends he finally decides that's enough research for one day!
Lessay Sonic finds out all this somehow. He borrows it briefly to look for something, then sees the search history. Tails finds him looking at the screen blushing, and he closes the computer as fast as he can, face all red. Sonic tries to play the situation off cool ("So... hedgehogs, huh?) but he is in a state of shock. He knows how extensive his buddy's research can be, but he didn't expect himself to be one of the topics, at least not like this. They'd probably have to talk about their feelings soon after.
