Witches:
crossover between Futanari, parasited, and hentaied

Part 1 futanari: A couple of teens are strolling through the woods late at night with heavy fog. They here a strange sound, chanting, and muffled screams coming from the other side of a clearing and go take a look. They see 3 haggard looking witches gathered around a pentagram (made of fire) and they have another young woman tied up (ropes and a gag) in the middle of the pentagram (meant to be a sacrifice). The girls are shocked at the site and want to help the poor girl tied up and try to sneak around to subdue the witches, unfortunately one of them steps on a branch that cracks loudly getting the attention of the witches who immediately summon roots/vines/branches to bind them in place. The witches then fondle the girls they just captured while interrogating them about why they're here teasing the girls when they answer truthfully, and punishing them when they lie. (sample questions: Didn't your parent's ever teach you to mind your own business? Why are you here? Does anyone else know you're here?) The first girl they question refuses to answer so one of the witches conjures a Futa cock and forces it in her. After cumming multiple times in the girl until she passes out from exhaustion, they turn their attention to her friend and ask the same questions. This girl is willing to talk after having seen what would happen if she didn't. Satisfied with the answers the witches knock her out to go back to their ritual.

part 2 hentaied: The witches have moved the girls to also be in the middle of the pentagram with the original captive though they're still out cold. The original still just tied up with ropes and a gag while the intruders are tied up with vines/roots. The witches are chanting again summoning a demon to take their sacrifice. After some time a demon appears in the center of the pentagram and goes straight for the original captive who is still awake. It uses it's tentacles to fuck the girl in every hole over and over until she passes out. At that time the intruders have woken up and the demon turns it's attention towards both of them and proceeds to fuck all their holes, at times going all the way through one into the other. After it has left it's seed (including a parasite) in each of the captive girls the witches' ugliness melts away, their ritual was successful, they have regained their youth. After some celebratory making out the vanish in a puff of smoke.

part 3 parasited: The captive girls all wake up the next morning not sure if they'd had a shared nightmare or if that really happened to them. They start walking out of the forest, and the intruders offer to let the original captive come back to their place to clean up. She takes the first shower and starts feeling funny. When she comes out from the shower she is feeling ravenous but plays it cool. One of the other girls goes in for her shower and once the door is closed the first girl makes her move on the third. She pins her against the wall and reaches down to her pussy and starts rubbing it while keeping the other had over the girl's mouth so that she can't scream for her friend. Her goal is to awaken the parasite within, we cut to the girl in the shower and see the parasite within her is awakening now too. Seemingly it takes either sexual stimulation of the host, or the beating of the water from the shower to awaken the parasites. Now that all 3 girls have had their parasites awakened we jump ahead to a future time when they are now the witches summoning the demon with someone else held captive.

Vampires - in the form of parasited:
part 1: It starts with a group of 4 friends at school and they're planning to hang out, except that one of them already has a date planned and suggests they al have a sleepover the following night and her friends agree. She meets her date and we see a montage of them having dinner and going for a walk before going back to his place. This is their first date and she is still a virgin so she's not planning on sleeping with him. They make out on his couch and as he is kissing other parts of her body he eventually bites her neck, she gives a brief whimper of pain ad says "what the fuck? Why did you bite me?" He lifts his head revealing his fans and she realizes what just happens. She has now been sired by him and will do his bidding. She gladly strips naked for him and will do anything he wants her to. After he has came in her multiple times, finally giving her a facial, he lets her go home for the night.

part 2: We see all the girls back at school asking how her date went. She is the shyest of them all so they would be shocked if she told them what really happened. She is also still under the vampire's influence so she tells them "He was charming, we talked for hours". They reconfirm their sleepover plans for the night and then we cut to them all at one of their houses gathered in the living room playing video games. Her friends are as shy about sex as she is so they're just hanging out, until she proclaims she isn't feeling well and needs to use the restroom. She stays in there for a while to the point where the friends get concerned about her and send one to check on her. The friend discovers that the door is unlocked so she opens it. The sight has her dumbstruck because the girl has changed into lingerie. She immediately closes the door and kisses her friend. The friend is still in shock and has no clue what is happening. The girl kisses her friend's neck then bites her to convert her. They fool around in the bathroom together for a while before she reveals that she has lingerie for her friends now too. They leave the bathroom together to return to the other girls. The 2 remaining are dumbstruck by the sight of their friends in lingerie. They ask "what is going on?" then the 2 vampires lunge at them and start making out until eventually they bite the girls making them all vampires. They then have a 4-way lesbian orgy.

part 3: The girls all go to the original vampire's home for a 4-on-1 reverse gangbang taking every drop of cum from him. By the end they will all call this their new home.

Mermaid:
a bit of a little mermaid parody for hentaied and parasited following the rules laid out in Pirates of the Caribbean On Stranger Tides but a little different. For theses rules, mermaids when dry reveal legs, however they have to be on shore, if they are still on a boat, it won't work fully.

part 1 hentaied: We see a mermaid swimming around under water and a ship passing overhead. She swims to the surface to see pirates (both male and female) dancing around drunkenly on the ship, partying the night away. One of the pirates really catches her eye and she can't help but dream about him now. She decides to visit the sea witch for help, she wants to become human herself, even if only for a few days to be with him. The sea witch agrees to help but it won't be easy. The only way for the spell to work is for the mermaid to trade her voice at the moment of orgasm. The sea witch takes the mermaid to an under water cave entrance where the mermaid can then dry off to perform the spell. The sea witch binds the mermaid using her tentacles then proceeds to fuck the mermaid in each hole using a couple more of the tentacles. When the mermaid screams out in orgasmic pleasure the sea witch leaves a parasite inside her that will be only be active for a few days leaving her mute. If she successfully gets the man to plant his seed (and only his) in her by the end of 3 days, she'll get her voice back and stay human, but if she fails, she'll die.

part 2 parasited, orgy: The mermaid is now washed up on the a rock in the sea. All she still has on is her sea shell bra, she is without her voice so she'll have to get her pirate's attention using other methods. She spots the ship and waves frantically. Someone aboard spots her and tells the crew to throw her a line. She climbs up to the deck and makes her move for the pirate leader. Little did she realize how ravenous the parasite would make her. She takes the pirate's cock out and starts sucking right in front of the crew. The men and women on deck are stunned but quickly get aroused. The men pull their cocks out and circle around her and the captain while the women start rubbing their vaginas. When she starts to ride her pirate, the women come and lick her breasts and pussy while the other pirates take their turn getting their cocks sucked. The Pirate then lets his crew have their way with the mermaid for a while until one by one they all cum inside her, and he finally gives her a facial. She is devastated and starts crying realizing that she failed and will only have moments left to live. The camera pans out to reveal her mermaid tail is back and she slowly loses her breath.

Really love this idea! Curious would it work to have them be part of a college sorority? And they are the only ones who stayed behind for the holiday?
