Mark: Emily! Thank God! We need to talk!

Emily let Mark drag her to his room.Mark:The symbiote's wasn't in my backpack when I got home. I think the container fell when your dad threw me out.

Emily walked closer to Mark and she put a finger to his lips.

Emily: Oh I know Mark.

Her clothes then liquify as the suit forms over Emily as Mark stares in awe and shock.

Emily: The symbiote told me everything and convinced me.

She began walking towards Mark.

Mark: Please don't kill me!

She stops as she leans in.

Emily: Why would I do that? You see, the symbiote told me that due to the modifications that you made, it needs energy which can be derived from sex. It convinced me that I need you and so does the symbiote.

Mark then stopped cowering as he stared.

Emily: Mark! I want you!

Emily then grabbed Mark and they tumbled onto his bed as she french kisses Mark.

Mark had a girlfriend and he knew that cheating would be a bad idea. But as Emily drives the monstrous tongue into him, his mind gets overwhelmed by the sex and his member gets erect as he thinks about the time with this symbiote-bonded girl.

Emily began undressing Mark. Unknown to him, the symbiote was stimulating her as she was naked inside the suit. The symbiote massaged her clit and squeezed her breasts egging her to continue. She reached out to the door as symbiote slime came out of her wrist and onto the door locking it.

Mark: Emily! I don't want it. Please!

Mark was still resisting. Emily stopped kissing him.

Emily: Your mind says no but your body says yes. Don't think I don't notice your erect dick.

She paused as Mark stared in shock.

Emily: You don't understand Mark. I'm not enslaving you. I'm just thanking you for this opportunity. I want you Mark and I know that secretly you wanted this symbiote on me.A tendril came out and caressed his dick as he stared, still resisting. The tendril wrapped itself around his pole as Emily continued kissing him and it began squeezing it. Mark began moaning.Emily realized that she was convincing Mark and the symbiote knew it was time.Symbiote:Yesss, Make love with Mark! Give me energy. Make ussss powerful!The symbiote opened a hole and Mark gazed down to see her wet pussy.
