"We can't examine you like that," Cathy scolded. "Nurse, remove the patient's trousers."
Elaine had been expecting to be a spectator, not a participant, but she was glad to be included. She hopped up from her computer chair and unsnapped her brother's pants, spreading the placket to reveal his pubic hair, and then worked the garment down and off of him.
Cathy stood looking at him a moment. "What do you think, Nurse?" she asked. "That looks like only a partial tumor to me."
Danny's cock was half aroused, as though it was waiting to be invited to rise. It twitched, moving from up against his belly to lie against his leg.
"We'd best prepare for he exam," Cathy said. She peeled the tee shirt off and then stepped out of her thong, smiling at the reaction of Danny's cock. "Nurse," she said then.
"What?"
"You're not ready. We can't examine the patient with these dirty clothes on."
"I'm just the nurse," Elaine said, suddenly shy again.
"Strip, bitch," Cathy said, grinning, and she reached for Elaine's shirt and helped her lift it over her head. "Undies too. We've got to be unsanitary, you know."
Elaine removed her panties, the dirty thrill coming over her then.
"Prep the patient," Cathy said, standing and watching Danny's cock rise and fall as he lay grinning up at her.
"What?" Elaine said stupidly.
"Boy, you're a dumb nurse. We can't examine a patient when he's not fully erect. Prep him. Pump him up."
Elaine's heart thudded in her chest. Her friend was asking her to touch her brother's dick. She licked her lips, wondering if lightening was about to strike her dead, and then reached for the wavering penis before her.
She grasped him, enjoying the soft, almost squishy feeling of his half hard cock. He hardened in her hand, growing firm as iron as she stroked him lightly. Cathy leaned in to watch, taking special note of the reaction on both of her friend's faces.
"Pull his sack out, too," Cathy said. "His balls are bunched under him."
Elaine slid her fingers under Danny's scrotum and pulled his balls out flat on the bed. The skin was soft and warm. His balls felt hot.
"Thank you nurse," Cathy said, moving in closer. "You can get the exam oil now."
Elaine moved back to get the bottle of personal lubricant from her desk and stand with it ready. Her pussy was so wet that she expected it to begin running down her leg.
Cathy leaned over and took hold of Danny's cock, stroking him slowly. Then she leaned closer and kissed the purple head, sticking her tongue into the hole and then licking around it. "Seems solid enough," she said. Cathy then slipped her mouth down over the stiff member, moving down until it hit the back of her throat and then up again, repeating the motion several times and finishing with a slurping smack when she finally removed her mouth.
"Tastes all right," she said. "May I get a second opinion?"
"What?"
Cathy grinned, studying the lust in her friend's eyes and wondering how far she would go. "Tell me if he tastes all right to you, Nurse," she said, still holding Danny's cock.
"But I, don't . . ." Elaine's mouth was too dry to finish the sentence. She didn't know what she would say anyway.
"Hurry up," Cathy said.
Elaine moved slowly, like a robot, and leaned over her brother's erect penis. Cathy was still stroking him, holding him upright, and Elaine moved closer telling herself that she was just playing along in the game. She was being a dutiful nurse, and, as such, she opened her mouth and took Danny's hot cock inside. She lapped her tongue around the shaft, savoring his heat in her mouth, and then she moved her head slightly up and down, licking the fat head as she felt his cock twitching.
