The goo strikes

"O-o-of course sir." She says, as she turns around to fetch some water from the water filtration system in her room. She takes a clean cup, and fills it with water; as you requested, before turning back to you and gives the cup with water to you. "H-h-here you go sir."

Than suddenly it moves inside her body towards her brain; overwhelming May's pleasure centers and making her pussy drip from the sexual shock. Her eyes roll back, as she is processing what is happening to her. "W-W-What is happening, sir?" She says, while her mind gets slowly taken over by the symbiote."*

You feel an energetic surge coursing through your body as your veins are getting darker for a moment.

You can't make coherent thoughts, you just see a vast array of lewd images, assaulting your brain. They're getting persistent.

Your whole body is getting stimulated. One thing is for certain, there is something new about your body. Something... odd. And with that feeling, comes an unnatural joy that shouldn't be there...
