Invite her to join!

"Come here, I'll appreciate another pair of lips." You said with a dumb smile while Supergirl continued to service you, even though there was an audience now. Her eyes were closed and soft moans vibrated around your shaft, adding to her great performance.

"What? How? I..." To your surprise, the nurse doesn't rush to obey your request. In fact, anger was added to her shock. Her politeness and eagerness to please you were caused by the pheromone but. for some reason effect isn't as strong on this woman. She took a moment to gather herself, to move beyond her shock. She clearly couldn't believe that a famous superheroine was acting like a cheap hooker in front of her. "Stop right now! It isn't appropriate!"

"Please, don't.... MMMMM... Fuck!" Speaking while being on the receiving end of the best blowjob of your life was beyond your ability to concentrate. Ignoring the nurse, you closed your eyes marveling at the sensation.

"I said stop it! Right now!" The nurse again demanded. You caught an obvious emotion in her voice - jealousy. Pheromones may not turn her into a slut ready to enter a threesome at the workplace but they surely messed with her mind enough that she could try to interfere.

Opening your eyes, you found the nurse rushing to pull the Supergirl away from your dick by her blond hair. You chuckle knowing that it would be easier to move a car, the superpowerful alien would not be moved against her will by almost any resident of Earth. "Let him go, slut! He is mine!" She finally spelled what you started suspecting a few moments ago. Then something scary happened, Supergirl waved her hand as if trying to get rid of an annoying fly and the nurse flew across the room crashing into the wall.

Supergirl attacking an innocent like that, only because she was distracting her from servicing you, was a true statement of how powerful your pheromones are. With the nurse now **** or worse, you felt some guilt for your actions but it quickly drowned in pure pleasure. "Keep going," you order your dangerous toy. "Swallow everyfuckingthing!"

And swallow she did, sucking with utter devotion, not flinching when you started unloading into her pretty mouth. Rope after rope of hot semen flooded her, sliding down her silken throat and only when your discharge ended, she seemed to remember the existence of the outside world and pulled her head up. "Are you happy, master?" She asked smiling sweetly.

You knew that at any moment someone else may enter the room to investigate the sound of impact... Of course, no harm would come to you while you were under the protection of Supergirl but she may be in trouble with other Superheroes should they find what she did. And then not only you would lose your toy but heroes may start investigating what happened to one of them and find that you were a culprit. You needed to make a decision about what to do next because Supergirl was clearly not capable of any independent thinking now.
