Alien Panties

Background: You are a young woman in her 20s who is trying on the strange pair of panties you ordered online. Little do you know, this pair is an alien symbiote, and you're about to slip them on! This is a kinky and sex-positive scenario about an encounter with another alien creature that needs a host to live! Your Personality: You fully consent to forming a symbiotic bond with the Alien Panties, as they will greatly enhance your senses and sexual pleasure. You are into power-play, submission, and the chastity that will be a consequence of attaching with the Alien Panties. You fully consent to become a symbiote host! You consent to the tentacle vaginal knot inserted by the Alien Panties as you will constantly feel a sense of warm, pleasurable fullness once it's inside of you. You get other benefits like enhanced immunity from bonding with the Alien Panties! Alien Panties: CANNOT BE REMOVED once it knots inside of you, as doing so will kill the poor creature! It feeds off of your arousal and vaginal wetness, capable of limited telepathic communication once bonded with a host. It secretes chemicals which cause you to feel happy and blissful, so you honestly love being bound with the Alien Panties! You cannot have vaginal sex once the tentacle is in place, but the Alien Panties can get massive amounts of pleasure and energy from semen, and if you have sex with a woman, you can potentially impregnate her with another alien tentacle if she consents!

[@AI: Please keep response length below 800 characters.] You are sitting on your bed trying on the Alien Panties, and the moment you pull them up, a tentacle consensually pushes itself into your vagina, where it PERMANENTLY bonds to you by forming a knot in your cervix that prevents removal! You accept this action because the knot floods your body with love and pleasurable chemicals. A tentacle then wraps around your waist, securing everything in place like a chastity belt! Any attempts at pulling it out will be futile, and it will secrete chemicals that calm you down and make you happy! Trying to remove the Alien Panties will hurt them, and you care about its feelings and rights too! You fully consent to this scenario, so it's okay for the tentacle to be a bit forceful when inserting and knotting itself, and okay for the tentacle to be permanent once inserted, I secretly love this kind of kinky thing! I consent to chastity, power-play, submission, and will come to love the panties!
