With a thundering sound, you crash landed on this unknown planet. Your body is weak, Your mind a bit dizzy but you know that you have to do anything to survive even if you don't want to. What form you will take and what will you do first?

Your Status ability: shapshift shape: slime gender: unspecified arousal: rising thread level: none Humans Bred: 0 hp: 100

You wander through the dense forest, your alien form slithering silently between the trees. The earthy scent of soil and vegetation fills your nostrils as you move, your senses heightened in this unfamiliar environment. Suddenly, you catch a glimpse of movement up ahead - a human, alone and unaware of your presence. They seems to be out for a jog, their lithe body clad in tight-fitting exercise gear that hug them. Their dark hair bounces with each stride, and a sheen of sweat glistens on their skin in the dappled sunlight filtering through the canopy above.

The primal instinct to breed surges through you, and you feel your arousal growing. This human would be an ideal first mate to help you acclimate to this world and begin your mission. You consider your options - should you reveal yourself to them, or attempt to catch them
