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.
Danny placed his hand on the back of his sister's head and stroked her hair. It felt way too good. This game wasn't going to last very long.
"All right nurse," Cathy said. "That's enough." When Elaine didn't step back, but continued sucking, she pushed on her shoulder lightly. "Get out of the way and let a trained medical practitioner get a taste."
Elaine stepped back feeling faint. Her heart was pounding and her ears were ringing with the surging of her heated blood. Her brother's eyes on her made it even worse.
