Make you give her 'medicine'.

Kitty walks up to you, still rubbing her hand inside her panties. "I instructed you to give me daily samples so as to find ways to counter any unexpected surprises of yours," she said sternly. "And now, not only do I find you having done unsafe sex with multiple women, but you won't take responsibility for your actions. What if you got those women pregnant? How would you provide for them?" She straightened herself up with a grin and slid her panties off, stepping out of them. "More to the point, you've infected me with this infatuation disease and I'm afraid there is only one cure for it..."

"Are you sure sex is the cure?" you ask suspiciously.

"Of course." She had pulled off her shirt, but left her doctor's coat on. "It's very much similar to providing an outlet for one's negative energy building. If given a way to release the pressure, it won't build and ruin one's performance..." She took your dick in her hand, started jerking you off while you stare with bewilderment. Her hand, lightly gripping your erection slid up and down to have you feel her soft skin, as well as feel how hard you had gotten since you arrived. "You see? I'm providing a necessary service to release the tension in your big manhood. You'll think more clearly when we're finished..." She licks her lips and kneels down, licking around the tip as she slowly pumps her hand on and on around your cock. Slowly at first, but gradually picking up speed. All of this was almost overwhelming for you, you tilt your head back and sigh from how talented Kitty was with pleasuring you down there. You pant a bit heavier as she kisses it all over, went into licking your entire length up and down, and finally engulfing you into her mouth.

"Damn..." you breathed. "I forgot how good you were." And she expertly had deepthroated your dick with only her mouth and gagged on it while fondling her breasts, tweaking her nipples roughly. The wetness and warmth of her mouth were stimulating your pleasure receptors greatly, and while she bobbed her head up and down, you thrust your dick further in! She was now making an ahegao face: smiling like a slut with her eyes rolled back as far as they could while happily gagging on your meat; you both worked well together to **** yourself to **** on your big cock. After 15 or 30 minutes, you finally pull out of her gasping mouth, her breathing heavily with her tongue sticking out while you milk your sausage quickly. You made the bald man cry, shooting white globs of cum on her tongue, though a bit of it was sprayed on her face. She was coherent enough to recognize a liquid on her tongue, so she swished it around and around in her mouth, humming softly.

Kitty swallowed your load, and she panted a bit quieter now. "Young man...?" she said to you. "If you help me take my medicine, this illness will be conquered in no time. Come back tomorrow for my daily dose..." She stood up, walked to the sink and used paper towels to wipe her face pretty clean. Then she looked back at you with a smirk. "Unless, Doctor, you think I need to 'take my temperature' the other way...?"
