To inject her with cow DNA

"You!" Spider-Gwen laid eyes on the High Evolutionary and yelled at him in anger, struggling against the high tech restraints before her headache made her wince.

"Finally, after one long and painful month of knowing a loose end has been escaping my grasp, I can finally exact my ****!" He made his way towards her, causing her to realise she was nude as the cold breeze made her plump nipples erect while she tries to scoot away from him.

"Oh yeah? Well, I'm not trapped in here with you. You're trapped in... here...with..." Spider-Gwen tried to put on a brave front with confidence, putting on a smirk despite the pain as she struggled against the restraints with all her might left in her sore body. That confidence was rapidly fading as the High Evolutionary strided right at her, evil intent in his soulless eyes.

"Oh? It seems to me that the only one trapped here is not me, but you!" He mocked her as he pressed a small button that appeared on a panel of his red metallic glove, causing the restraints to deactivate and fall to the ground, clattering.

Before Spider-Gwen could get to her feet, a syringe with pink liquid emerged from the High Evolutionary's other glove. He jabbed the syringe into her exposed large breast, liquid injecting into her tits, before the syringe retracted back.

"What did you-" Spider-Gwen got up angrily, fists raised before her breasts started to feel weird, making her sway and hold on to focus to maintain her footing while she gave the High Evolutionary an angry glare.

"A special mix of cow DNA and new men concoction. You'll see the effects slowly start to set in." He stepped back.

"Cut the-" Before Spider-Gwen could swing her fist at him, the weird feeling in her breasts increased tenfold, making her feel drowsy as her boobs slowly grew, starting to leak thick and creamy milk from her round plump nipples.
