I think that what is needed is a video that involves more than two people or a saga of several chapters, where an infection occurs that spreads to other people.
The infection can start in a house where a ****** and her ******** are watching TV and spread the news that they have discovered in a hospital/research center, some cases of people infected with a disease that makes them behave in a sexually extreme, looking like zombies who just want to have sex and with different people, without knowing that it is due to a parasite.
After this the doorbell rings and a friend of the ********'s university arrives at the house and they both go up to the room to go study. The ****** stays downstairs watching TV, after a few minutes the ****** goes to the kitchen to wash the dishes, but the tap water comes out viscous, which makes her worry, she checks the water pipes and does not realize that the viscous water keeps coming out and ends up spilling on her and a parasite ends up slithering under her skirt and then inside her, causing the conversion process, although trying to resist she walks towards the room, but falls due to the growing excitement inside knocking down a photo of her ******** that falls right in front of her, she begins to masturbate, looking at the photo with more and more intensity until she can't take it anymore and her eyes change.
The girls upstairs hear the noise, but they don't care and the ******** leaves the room and goes to the bathroom. the ****** gets up and with a smile on her face she walks towards the room of her beautiful ********, wishing to satisfy her new desires to possess her, to infect her and her friend.
She arrives at the room and when she enters she finds the friend alone, the girl is scared to see the condition of her friend's ****** with a viscous substance coming out of her mouth, worried she asks if she is okay, the ****** smiles and answers that better than ever, and that soon she will feel very well too. He jumps on the girl and forcefully manages to hold her and prevent her from making a noise, the girl resists and lets go letting out a scream, which is stopped by the ****** who kisses the girl, spilling the viscous substance on her mouth, breaks or removes her clothes and releases a parasite on the girl's body that comes out of her mouth.
The parasite enters the girl and begins its conversion process, while the ******** who had gone to the bathroom, realizes that the water has a strange texture and goes to talk to her ******, but cannot find her, feeling the noise in her room she runs towards there and when she enters she finds her friend on the floor touching each other more intensely and her satisfied ****** on the bed, who when she sees her ******** runs after her to infect her, the ******** runs away, but does not get very far, her ****** reaches her, but they struggle for a while, in the room, the friend finishes her conversion, her eyes change and she gets up looking for a victim for her satisfaction, finding the ****** and her friend fighting, the ******** asks her friend for help, but the friend approaches the ****** and kisses and touches her, which makes the ******** horrified.
The two infected then come together to convert the ********, who once converted joins the rest in a threesome, enjoying the rest of the time of her sexual pleasures.
At the end there may be a scene that gives an indication that there will be a sequel, perhaps at the friend's house, where they convert the ****** and ****** or sister, etc.
