Batman uses his many skills.

Bruce knew that if he didn't take control of the situation that he would cum in or on Selina. He had to do something. That's when he remembered some of the skills that he had gathered to be come Batman. Which had included sex skills. So that he wouldn't be broken in this type of trouble.

Bruce enjoyed the sensation of moisture and pressure on his cock from Catwoman's mouth. But he altered his breathing so that it show down and he could control the pressure of his cock. He could feel the urge to cum and the orgasm comming. But with the sex training that he had recieved he held back.

This frustrated Catwoman. She pulled her lips off with a slick pop! "Why aren't you cumming? Any other man would have cum by now!"

It was Harley who clued in first. "I think I know! He must know some of that Tantricky sex stuff!"

"You mean Tantric sex. But you're right. The basic idea of the technique for a man to hold in his cum and orgasm to recieve superhuman abilities. To spill a single drop of cum is to have him loose a great amount of energy and power." Ivy said.

"We're going to need some help to get him to fuck. Or else those Tantricks are going to get him to stop." Harley said.

"Give me a turn and I should have something that might work!" Ivy said with a smile as she headed to the backroom.
