A syringe

“Lactite.” He read off the label. “Inject directly into the breast to begin uncontrollable lactation. So nice of you to label things. I assume this is what you used on her. Where’s the antidote?”

“There is no antidote! She’s going to be my cow forever!” Dr. Bluder said, wriggling, trying to slip out of her coat so she could escape.

“That’s not so good for you.” Ultraboy snapped, injecting her directly in her right tit, then tossed her up, raced back into the room and retrieved the entire tray of syringes. He caught her before she hit the ground and in a superhumanly fast movement injected two in her huge left breast and another in her right, double the dose that overcome Ultramom’s impressive powers and kickstarted her milk production.

He tossed the tray and the used syringes behind him. “Now, unless you want to be my cow forever, you’d best tell me where the hell the antidote is.” He deliberately mimicked her threat.

He could see milk beginning to soak through her top already. “No.” She squeaked.

“Yes.” Her hand rose to her own breasts, squeezing hard, forcing the milk that was already growing within her out and relieving the horrible growing pressure within her breasts, bringing herself a shocking amount of pleasure. The same pleasure that he could hear coming from Ultramom in the other room, the same odd, overwhelming ecstasy that overcame superhuman self-control, such that her equally superhuman senses couldn’t hear a conversation taking place not twenty feet away. His other hand caught her free hands, pulling them away from her magnificent rack, such that she couldn’t relieve the pressure. The smell of sex filled the air and when he looked down, he saw that she had soaked through panties and business skirt alike.

“The antidote.” He said as she writhed, no longer attempting to get away, now she was trying to grind herself against the boy, no, the man holding her up.
