"Clean me up, Nurse," Cathy said breathlessly. "Tell me if he still tastes healthy."
Elaine only hesitated a moment before leaning to suck her brother's cum up off of Cathy's hot skin. She licked down her stomach and slurped the cum that pooled in her belly button, the smell of Cathy's overheated cunt filling her head. She fondled her own pussy as she completed her task, trembling against her hand.
"Now clean up the patient," Cathy said.
Again, Elaine's hesitation was only a split second. She knelt over her brother and took his cock into her mouth. Now she could taste Cathy as well as him. Now she was really too far gone to stop at anything. And Danny's cock grew hard in her mouth, nearly as firm as it had been at the beginning. Elaine was concentrating so hard on her pleasant task that she didn't notice Cathy get up and move behind her until she felt her friend's hand slip between her legs to cup her pussy.
"You're wet," Cathy said, sliding two fingers into her. "Hot."
Elaine arched back, still holding her brother's cock but wanting to feel more of her friend's moving fingers. Danny lay on the bed watching his sister lift up, her head moving back beside Cathy's head as Cathy moved three fingers in and out of her sopping pussy.
"Does the patient have any rubbers?" Cathy asked as she kissed Elaine's cheek.
He rolled away from the girls and ran to his own room, returning moments later to see his sister leaning on her forearms on the bed, her butt up against Cathy's stomach as the other girl was reaching around to rub her clit. Elaine was shaking, about to cum, and Danny watched in fascination as her orgasm erupted, leaving her lying on her stomach with her buttocks twitching.
Cathy took the package from Danny's pliant fingers and opened it. She grasped his cock and rolled it expertly over him. "Test your hip movement again," she said. "Fuck your sister."
Danny's hands were trembling when he put them on Elaine's hips. "El, do you want me to do this?" he asked. Elaine nodded her head against the bed, not quite able to speak yet.
Cathy grabbed Elaine's hair and pulled her head back. "Do you want to fuck your brother?" she asked. "Speak up."
"Yes," Elaine said. "Fuck me." Then she pushed herself up, her voice gaining strength as she looked back at Danny with the wild eyes of a woman possessed. "Fuck me hard," she snarled. "Fuck me like a bitch. Slam me with that cock."
Danny pushed her legs a bit wider and bent his knees to get himself level with her snatch, and then he pressed himself against her, sliding up and down on her dripping labia until he found the proper spot and pushed his cock all the way in.
"Oh, Lord," he sighed, and then he began slamming his cock into her hard and fast.
Elaine had an orgasm right away and another only moments later. She arched back against him, reaching down to feel him moving in her. She pulled him close and kissed him, sucking at his tongue as her pussy was sucking at his rampaging cock.
Danny pushed her down then, rolling her to her back and entering her again so he could see her. God, she was tight. Hot. Squeezing his dick harder with each spasm of rapid orgasms. He was damned to hell. He knew it and he didn't give a shit.
After ten minutes, Elaine pushed him away and lay quivering uncontrollably. Her body convulsed from an overload of orgasm and was unable to take any more. But Cathy was there to take up the slack. She straddled Elaine's legs, offering up her own hot tunnel.
"Take the rubber off," she said, spreading her legs and kissing Elaine's stomach. As Danny rolled the condom off, she kissed up to suck at Elaine's nipples, causing her body quiver from the new stimulation.
Danny didn't ask permission or say a word. He slammed his cock into Cathy's pussy and fucked her hard and fast, watching as the girl moved up to kiss his sister's lips, her throat, and again to her breasts. The sight helped him now, bringing on a new orgasm only twenty minutes after the first.
When he felt himself nearly ready to erupt, he pulled out and pushed Cathy aside. He pulled Elaine's arm and dragged her to her knees on the floor by the bed. She didn't need any more invitation than that. She took Danny's cock into her mouth and sucked the head, pumping her fist on the slick shaft.
The hot spurt of her brother's cum filled her mouth, and she sucked until his cock had quit spewing and began to go limp. She sucked until he had to push her away, shaking, and fall to his own knees.
Danny kissed Elaine heedless of his own cum in her mouth. He kissed her because he loved her and he was grateful to her and he could think of nothing better than to stay like this forever. And, when Cathy knelt beside them, both he and Elaine kissed her, too.
This was indeed a graduation day. They weren't sure what life after graduation would be like, but they were happy with the way it had begun. Eventually, they fell asleep in Elaine's double bed, Danny in the middle and the two girls curled against him.
Cathy drifted off to sleep feeling well satisfied. Nobody really knew her family. She hadn't known them, and they apparently didn't want to be known by her. Fine. She'd make her own little incestuous family right here. These guys wanted her, and she slept content to be wanted by somebody.
