The symbiote fed on her!

Drawing sharp, quivering breaths Stacie laid still on the floor as the vile liquid washed over her. It cupped her well rounded breasts, surrounding them with its foul presence. She yelped as it tightened around them, squeezing the soft flesh wantonly as what felt like two small maws latched onto her nipples. Greedily they suckled, her toes curling up and her nipples growing erect at this unwanted attention. She tried to say something, but the only noise that made it past her lips were an audible, drawn out whimper.

"How pathetic." The voice said with contempt. "According to your own mind you're some kind of hero among your people. But surely that cannot be the case, a hero wouldn't buckle to such light stimulation. Are you a pervert?" The last question rang out in her mind, her heart picking up speed as it pounded in her chest.

"No, get off me..." She managed to whisper with great effort, the simple act of uttering those few word leaving her feeling utterly exhausted.

"Are you sure about that?" The voice asked as the goo crept up between her legs.

"Hnng!~" She whined, her legs spasming as the symbiote turned the heat up.

It was as if it vibrated, kissed and warmed her at the same time. It's infernal embrace covering her mound to stimulate every part of her. Her head fell backwards and her back arched against the floor as she felt it pool up against her sensitive little nub, gyrating, tugging and buzzing against it at the same time. That's when she felt the pressure against her entrance.

"Hmm let's see." The symbiote mused, searching through her memory. "Ah yes, yes that's good. I quite like that." It laughed.

The first push made Stacie tremble, her voice a low whine as it pressed itself through her puffy wet lips and into her body, reshaping itself as it went. What had been a small tube became shaped like a thick cock, crowned by an engorged tip that stretched her out as it pushed further inside. Stacie wailed and tried her best to kick and writhe, but it was no use. The symbiote had utter control, and all it allowed her was enough freedom to squeal but not enough to actually stop it.

It mocked her as it began pistoning in and out of her with its hungry maws nursing at her breasts, its vile goo slithering all over her skin, engulfing her in wet heat. "This is what you've wanted all along." It said, "otherwise your cunt wouldn't be this wet. All those great monsters and villains you've faced, and not one of them were strong enough to fuck you were they? It always disappointed you." The symbiote continued, thrusting its inhuman member deeper inside of the former heroine's squirming body.

"No, no, no oh God no I don't want to cuuum!~" She thought, her mind racing as she rocketed back and forth under her new master's ****.

"GIVE IT TO ME, LET ME FEED!" The voice boomed as Stacie broke down and climaxed, her insides wrapping hard around the symbiote's member as it fed on her sinful wetness.

As the orgasm subsided Stacie was gone. In her place a new heroine stood, smiling as she looked down on the lab-tech that was just regaining her consciousness.

"Hello baby, missed me?"
