They stop... and watch.

The couple stop fucking and turn to see their frined rocking hard and fast on your demon cock. They are scared but the male starts to stroke his cock, horny from the sex and the sight of their friend being converted. She rides expertly and the couple whispers "fuck her demon. Fuck Olivia hard. Oh that's it." It is no improvement that she talks in the act but it makes her work harder.

Before long, wings split out of her back and catch the masturbating couple by surprise. Olivia's skin changes to an almost indigo colour and her skin tightens. Her breasts increase and her face sharpens to a demonic norm. She screams and scratches your chest. Blood seeps slowly and she turns around. "Olivia wants more..." She moves her attention to the male. "Come on Patrick. You need this..." Patrick stumbles against a wall and Olivia's mouth falls straight onto his cock. He moans and closes his eyes tight.

The masturbating girl falls to her knees, staring into your eyes. Without speaking she crawls towards you. She runs her hand up your muscular thigh slowly. Normally the Lilith experience is fast and rough but this girl was in a trance. Her finger dragged up your wet, massive cock. Her finger brushes off some cum from the tip of your cock. She watches it flow down her hand and licks it up. She groans, tasting the sweetness of the demon sperm.

The scene quickly turns from two couples to a foursome with Olivia fucking Patrick, Patrick licking the girl's pussy and her sucking your cock. The conversion of the couple is swift as Patrick becomes a dark green colour and the girl turns a crimson hue. They all continue to fuck as you get up. You transform into your human shape as the trio roll around in your demon sperm covering the floor.

As you exit, a janitor and a teacher approach the bathrooms. "What's going on in there?" The teacher asks you as you grab the duo and throw them towards the horny demons. You close the door as you see Olivia ripping the clothes of the janitor. You wander off, stronger and becoming more powerful.
