Write a detailed story, including dialogue, in the Batman universe. Batman wakes up, tied to a bed. As he comes back to his senses, he remembers how he ended up in this situtation. A leather-clad pair of thighs wrapped themselves around his neck and choked him unconscious. The culprit, Catwoman, and a scientist enter the room and approach Batman. The scientist asks Catwoman to collect his semen in the provided catch cylinder. Once she has hilled it, she can keep Batman and do with him as she pleases. The scientist leaves and Catwoman begins to pleasure him, milking him against his will. After multiple orgasms, overstimulating him again and again, the catch cylinder is full. The scientists collects his price and leaves the lovebirds on their own. Catwoman, happy to have Batman all for herself now, begins to work on his member with her eager mouth. This time, non of his seed will be wasted. All of it is yours.
