Turns out Charissa likes sex as much as I do!

"Go ahead," the orderly said. "Do what you need to do."

"Actually, what I _need _right now is to feel your ass against my cock."

I certainly was emboldened by my escapades in the maternity ward. The shock that flashed across Charissa's face gave me pause. Did it stop working? I worried.

"Sir, I can't do that," she said as she started to loosen her scrub. "And I can't believe you would say something so ... crude." She turned her back to me and slid her pants down her legs. Her tan ass was round and firm, and I could see the barest hint of her pussy in the gap between her smooth thighs.

I approached her from behind and placed my penis between her cheeks. "Looks like you can do it, Charissa."

"What?" she asked, surprised, as if she hadn't realized what she'd been doing. "What's going on?"

Moved by the intimacy of our private room (OK, it was a bathroom, so what?), I decided to tell her. "I had pubic enhancement surgery, Charissa. I'm actually the first person ever to get it. And Dr. Han gave my penis pheromones that make women do whatever my cock desires."

"Holy shit," she said as she massaged my dick with her ass. "That's so fucking cool!"

I pulled away, surprised by her reaction. "Um, what?"

"That's amazing, sir," she said. She turned around, facing me with her pants around her knees and her neatly-trimmed pussy on display. "Can that cock make me ride you like an animal, sir?"

Now it was my turn to say it. "Holy shit."

She giggled and walked toward me, pressing me against the wall. She discarded her pants but left on her dark blue orderly's shirt as she grabbed me by the neck and pulled her legs around my body. Her forwardness was a huge turnon, and without another word from me, she slid my cock deep inside her with the agility of a gymnast.

I thrust inside her while she grasped me like a stripper pole, and her moans were louder than mine as we came together a few minutes later. She hopped off of me and started to wipe herself with toilet paper when she noticed my cock was still hard.

She giggled again and asked, "Did Dr. Han do anything else, sir?"

"How does endless cum sound to you, Charissa?"

"That sounds amazing, sir," she said as she knelt in front of me and took my cock in her mouth. "And it tastes amazing, too!" Seeing this 19-year-old's lips around my penis was a dream come true, and though her mouth wasn't very big, she really knew how to use it. Now I could really feel a difference between the **** sex I had before and a willing partner who enjoyed the pheromones. Sure she wouldn't ordinarily have fucked me in the staff toilet, but since she didn't have a choice, Charissa seemed plenty happy to oblige.

"Please cum in my mouth, sir," Charissa said and the hummed around the head of my penis. I grabbed her hair and pushed myself deeper inside, and a fantastic orgasm shook me from head to toe as I blasted my load in her throat. She gagged a little, but she was smiling when I pulled out. She acted just like in one of those pornos - she played with my cum on her face, running it over her lips with her fingers and showing me she was loving the taste. "May I swallow your cum please, sir?" Charissa asked.

"Yes, Charissa, you may," I said, and with a happy laugh, she downed the whole load at once.

"My goodness, sir," Charissa said, still enchanted by my engorged penis. "You do have some stamina!"

"How much stamina do you have, Charissa?" I asked.

She laughed. "I have quite a lot, sir," she said. "But actually, I have another idea that might interest you."
