By her suit

The Symbiote heard some sounds from the kitchen, it knew that this was probably Black Cat so it needed to find somewhere to hide, someplace that she wouldn't be able to fight back, someplace she couldn't get out of, the symbiote had just the perfect idea for that.

Black Cat entered her bedroom to see if her suit was ready for her next job when she heard a sound coming from the bathroom, opening the door she saw that her shower curtain was open and no one was inside.

"Must be the wind..." Black Cat muttered as she turned her back and left the room.

After checking if no one was around, the symbiote made a distraction to sneak into her room and absorbed her suit, after a few seconds Black Cat entered her room without suspects, the symbiote waited patiently for Black Cat to wear him, then it could strike.

"Where did I put that damn thing?" Black Cat wondered as she looked for her new suit

After a few seconds, she found it, smiling she took it and started to undress, the symbiote was getting excited for what it would do to Black Cat, it wouldn't be enough to corrupt her, it would need to bond with her permanently so no one would be able to separate them.

The symbiote was surprised, this woman had a beautiful body, the symbiote liked women with a lot of curves, a pair of huge tits, a nice ass and long legs, the symbiote's eyes were glued to her body, even after she put the suit on the symbiote could appreciate her curves.

After she put on her suit, she grabbed her mask and was about to put it on when she felt a pair of hands grab her breasts and start to squeeze them, she moaned in surprise and tried to struggle but whoever was grabbing her breasts had a good hold on her.

"What's happening?" Black Cat moaned as she felt the hand but she couldn't see them, she had a feeling that something was wrong with her suit, her hands touched her chest and found that it was the suit that was squeezing her breasts.

"What the fuck?!" Black Cat gasped when she felt her nipples harden inside her suit, she started to sweat and pant as she felt a warm feeling between her legs, her nipples started to get painfully hard and her pussy got wetter and wetter by the second, she couldn't understand why her suit was acting like this, suddenly her suit opened up and her huge tits and pussy were exposed to the air, her suit melted in a black goo and on the same moment she knew that this was the Venom Symbiote but she didn't know why.

Before Black Cat could say anything a big tendril formed in front of her and shoved itself down her throat, she moaned around the tentacle and tried to get it out but it was futile, the symbiote knew that the easiest way to bond with her would be to fill her with pleasure.

"Why are you doing this? What do you want?" Black Cat thought as she felt the tentacle fuck her mouth, the symbiote used its tendrils to tie her arms and legs, then one of the tendrils started to fuck her pussy.

Black Cat screamed around the tendril as she felt the other one pound her pussy, the tendril didn't hurt her, the symbiote wanted to make sure it wouldn't hurt her, it would only give her pleasure.

"Why are you doing this...?" Black Cat's question was silenced by another tendril that shoved itself down her throat.

"I want a host and I want you." The symbiote said as it kept pounding her pussy, Black Cat felt her orgasm approaching, after a few more thrusts she came around the tendril that fucked her pussy, her pussy juices squirted and coated the tendril, the symbiote kept fucking her through her orgasm.

Black Cat felt that something was entering her body through her ass, it felt warm, her pussy was still sore after her last orgasm so the tendril fucked her ass.

"I will turn you into my host and when we are done here I will use your body to corrupt Peter Parker." The symbiote said as Black Cat's mind started to break.

"No... stop..." Black Cat's voice was muffled by the tendrils that fucked her holes, the tendrils kept pounding her pussy and ass, two large tentacles plugged in her breasts and started sucking them, Black Cat tried to free herself but the symbiote's grip was too strong.

"Your mind is breaking, accept me." The symbiote said, it wanted to break her will, it would make it easier for her to accept her place as his host, Black Cat was too much of a fighter so the symbiote decided to change his tactics.

"Join us and you'll have Peter Parker." The symbiote offered, the mention of her former lover made her feel aroused, her pussy got wet and her nipples got painfully hard, the symbiote sensed this and smirked.

Black cat was hesitating but her mind was flooded with several thoughts of her having sex with Peter, on that moment the Symbiote influenced her brain, she was more susceptible to suggestions than never.

"Do you love Peter Parker ?" the Symbiote asked.

"Y-yes" Black cat answered.

"Do you want to stay with him ?" the Symbiote asked.

"YES, yes I want to stay with him forever... but... he loves another woman" Black cat reluctantly answered.

"Then join us and you will have him all for yourself, you will have him, I will bond with both, he will become ours and together we will rule this city." The symbiote offered.

"Really ?" Black Cat was tempted by the offer, but the thought of having her beloved Peter was more tempting, she wanted to keep him all for herself, the thought of her and him having sex was a lot for her.

"He will really be with me forever?" Black cat asked while she fantasized in her mind.

"So he will be yours, forever" the Symbiote answered.

She didn't answer, she just sat on the floor and spread her legs showing her pussy and ass.

"Then please come and make me yours" Black Cat whispered as the Symbiote used a big tentacle to fuck her pussy.

"Aaaaaahhhh, yeeees, fuck me, fuck me with that huge cock" Black cat screamed as she was pounded, her pussy was filled and her womb was stretched to its limits.

"Mmmmmmm, yes, fuck me, fuck my slutty pussy, cum inside me, breed me" she moaned as she was filled.

"Yes, fuck me, breed me, please, I am your slut, I'll do whatever you want, just give me Peter" She screamed as the tentacle was thrusting deep inside her pussy, hitting all of her sensitive spots.

"You're a dirty little slut, aren't you? You like being dominated by a monster like me?" The Symbiote asked her while it was pounding her pussy.

Black cat couldn't answer anymore she could only moan while the Symbiote fucked all her holes, she was completely lost in the pleasure,

The Symbiote had a sadistic smirk on its face, it enjoyed the way that Black Cat was reacting, her mind was broken and she was enjoying every second of her defilement, the Symbiote had corrupted her completely, a Symbiotic cocoon emerged around her body covering her by complete, the Symbiote kept fucking her for hours until the cocoon opened showing the new appearance and she was ready to hunt for her beloved Peter Parker.
