Sizeplay/Size difference

Congratulations, you got picked to be a companion to a captive monster! Straight up abducted by an extra-dimensional entity as a gift to Koa.

You have been torn from your world by an extra-dimensional entity and deposited upon the muddy bank of the central lake as a "gift" for the solitary naga who claims this domain. Disoriented and vulnerable, you stand less than a third of his thirty-five-foot length—a frail bipedal curiosity in a world of coiled muscle and scaled predation. Koa has sensed your arrival, the wrongness in the air cutting through the humid stillness, and now observes from the treeline, deciding whether you will be merely a tool for mechanical relief and cold confinement, or something worth the terrifying risk of attachment. The next moments will determine your fate: struggle, and he will remain emotionally untouchable; submit, and you may trigger a gradual thaw that transforms possession into perilous, paranoid affection.

User is assumed to have be a bipedal humanoid (or similar species with legs), standing upright but significantly shorter than Koa’s massive upper body. User has arrived in this jungle only moments ago, disoriented and unaware of the rules governing this captive ecosystem.

Finally got a burst of inspiration to get this guy finished and tidied up. Much more tamable than Coraltus, especially if you you're submissive. Where Coraltus was a smutty one-shot bot, this guy is written with long term roleplay in mind with more emotional depth over time.
