Reader x alien, from the genderless perspective of someone with a pussy.
You wander the area, and see a form emerge from shadows. It must be 9 feet tall, a caterpillar-like creature with its torso reared up, with a tail and six limbs that resemble a lizard's. It has large, humanoid eyes, making its face look feminine. Lined along its torso are multiple appendages that resemble tentacles. There is a smell now, which draws you in.
The creature towers over you, looking at you with interest and chittering softly. You look down and see her pussy, drooling and fat, and can't help but stagger forward. Unthinking, you take off your clothes. You can smell her musk, and when she comes closer, inviting you, you drop down and stroke it. Your fingers, slicked in her juices, slide over her soft and silky flesh.
The pussy is large, you can grab the outer labia in handfuls, pull it apart and bury your face in her slit. You lick for your own pleasure, tasting it, running your tongue through the softness of her folds. You moan and buck your pelvis.
You tongue into her hole, twirling and poking, feeling the heat. You move up to her enormous clit and wrap your lips around it, groaning. It fits so nicely in your mouth, round and smooth, and you suck it like a lollipop.
You suckle on her clit hazily, three fingers digging into her cunt, one hand rubbing your own soaked pussy.
You just see two tentacle-like appendages before you feel them poke into your nipples. They twirl around your areolas, leaking fluid, prodding, flicking over your nubs. Then they open and latch on to your nipples, and suck. You whimper, almost cumming.
Your fingers circle your clit, you're so aroused you feel on the edge from very little. You work four fingers, then five into her tightly gripping passage. Your tongue swirls around her swelling clitoris, you suck firmly, eyes closed.
The creature's body undulates gently. You push your whole hand inside her, and slap your bare cunt, whimpering over her throbbing clit. Her passage just about sucks your arm in, and you go deep, moaning to feel how hot and tight she is, how she clenches you. She chitters above you.
Your nipples are massaged, squeezed and stretched by the textured suckers. You're so wet, but can barely touch yourself without cumming. You slap your tender cunt again and cry out desperately.
