Lisa Simmons entered the house quietly, not wanting to wake anyone up.
It was two o'clock in the morning, and she had just returned from a party at a friend's house. She quietly entered her room, almost completely closing her door before turning on her light. Her grandparents, who had come to stay for a week that was to be capped by a family reunion, were staying in the room down the hall, and she didn't want to disturb them.
Lisa collapsed onto her bed. She was still upset that her boyfriend hadn't been able to make it to the party, especially since she was horny as hell! She felt a desperate need to get laid. With all the family around, she was not going to be able to be out like usual.
Lisa was eighteen and almost constantly horny. Luckily, she had a killer body that kept a constant stream of boys sniffing around her like a dog in heat. She had black hair like her mother, worn to mid-back with bangs in the front. Her eyes were slightly almond-shaped, she had a cute button nose and a pouty little mouth. Her breasts were large, the size of small grapefruits and on her 5' 3" frame, they looked awesome. Her ass was compact and firm, like a little buff bodybuilder.
Getting up off her bed long enough to remove her clothes, Lisa put on her skimpy lace nightie and lay back down.
Her hands slowly caressed and squeezed her melon breasts; her fingers rubbed her dark nipples, teasing them until they were hard. Then she slid her hands down her flat stomach to her awaiting pussy, spreading her short, supple legs and arching her hips as the middle finger of her right hand slid back and forth along her pussy lips before sliding inside. A gasp escaped from her throat.
Lisa was wet almost immediately, her fluids flowing freely onto her fingers. She stroked the middle finger of her left hand in her pussy, getting it well-lubricated, then slid her hand underneath her ass, slowly pushing her finger into her asshole. She inserted another finger from her right hand into her pussy, then began finger-fucking her pussy and asshole simultaneously.

About this time, Grandfather Jack had just finished going to the bathroom, and was heading back to his room. At sixty-five, he was still as strong as a bull, 6' 2" and 235 pounds of mostly muscle from his career working as a fireman.
He noticed that Lisa's door was open just a crack, and that her light was on, so he casually glanced in to see what she was doing awake at this hour.
His eyes widened as he saw her scantily clad young body writhing on her bed as she masturbated. Her large, full breasts pushed up through her nightie; her fingers moved rapidly in and out between her legs. He could not see her pussy because of her hands, but he could imagine the moist folds of her lips, the hot depths of her womanhood.
To his shock and amazement, his cock was rock hard inside his pajama bottoms.
Jesus, I shouldn't be watching this. . .she is really getting it on. . .oh my God!
He cautiously opened the door wider to get a better view, his hand going inside his pajamas so he could stroke his cock.
Lisa noticed the movement of the door out of the corner of her eye, but was too close to climax to stop. She casually glanced over that way several times, until she saw her grandfather's face once as he moved briefly into the light. She smiled to herself.
Well, if he wants a show, let's give him one!
Lisa continued to pump her fingers in and out of her pussy and asshole, going faster and faster until she climaxed, biting her pillow to keep from screaming in passionate release. Her body collapsed on the bed, her breasts heaving.
She turned her body toward the door, spreading her legs slightly farther apart, so that her grandfather got an eyeful of her pussy, her inner thighs covered with her love juices. Then she got up, turned out her light, and crawled under her covers.
She could hear her grandfather going into his room across the hall.
Lisa smiled to herself, wicked thoughts dancing in her head.
This could be fun, she thought.

The next day, Lisa watched her grandfather, waiting for the chance to get him alone. Her chance came late that afternoon while he was in the spare bedroom that he and her step-grandmother were using during their visit.
Lisa casually strolled into the room, closing and locking the door behind her. She smiled coyly, slowly rubbing her pussy through her jeans.
"Lisa, what do you think you're doing?" Her grandfather had a shocked expression on his face, but Lisa noticed that his eyes never left her crotch.
"Just thinking about last night. You remember last night, don't you?"
"I don't know what you're talking about."
"Sure you do. Last night, when you were watching me play with myself. I really liked you watching me. It got me all hot and wet. I'll be doing it again tonight, if you want to come by and watch some more."
"Lisa! You shouldn't say such things."
"Why not? I know you enjoyed yourself." Lisa walked up to her grandfather and began rubbing his cock with one hand, still rubbing herself with the other. "You don't have to come if you don't want to, but I'd really love it if you would. You can even come in the room this time, so you can get a closer view."
Lisa turned and walked to the door, unlocking and opening it. Her grandfather just stood there, staring at her. She turned back briefly before leaving the room.
"See you tonight," she said with a smile.

That night, Lisa's grandfather lay awake in bed, determined not to leave his room. But no matter how hard he tried, he could not get the image of his granddaughter's nude body out of his head. He felt his dick stiffening as he thought back to the night before.
The next he knew, he was quietly getting out of bed and leaving his room. All he could think about was seeing his granddaughter's sensuous body again.
Across the hall, he could see Lisa's light on. Her door was open a few inches, just enough for her light to show in the hallway. He quietly stepped up to her door and peered in. She lay naked on the bed, her legs spread wide. Her eyes were focused on the door waiting for him to arrive.
"Come in, Grandpa, I was just about to start without you."
He walked into the room, shutting the door behind him.
"Don't forget to lock it. We wouldn't want anyone to interrupt us."
He locked the door, then walked over to her bed, sitting down next to her. His eyes roamed up and down her body, staring at her firm breasts, her flat stomach, her trim bush. His mouth felt so dry, even after all the women he had bed -- this was his sweet granddaughter.
Lisa sat up and reached between his legs, grasping his hard-on through his pajamas. Her little hand closed around a thick member and Lisa licked her lips unconsciously. She should not have been surprised. As she gazed at her grandfather's hairy muscular chest and weathered face, a manly cock was the only kind he could have had.
"Oh my, you're hard already."
"Lisa, we shouldn't be doing this. I mean, you are my granddaughter."
"So what? Why should that stop us from enjoying each other. Let me loosen you up a little, and maybe you'll relax and enjoy yourself."
Lisa unbuttoned his pajama bottoms, slowly, seductively, as the cock underneath pressed against her fingertips. When the second button popped open, the underside of Grandpa Jack's dickknob jerked into view. It was the size of a fat plum. The third button came undone and half of his shaft forced itself into the bedroom's air.
"God, Grandpa!" Lisa said excitedly as she hurriedly undid the last button and his nine inches bobbed up, fully exposed. It was heavily veined and oozing pre-cum from the wide slit on top. Wrapping her left hand around his shaft, she started slowly jerking him off, while her other hand moved to fondle his heavy gray-haired balls.
"Oh, Lisa, that feels wonderful," Jack grunted, "but it's not right."
"Right or not, I don't think you'll be leaving, will you?" Lisa said confidently as she moved her body, shifting into a crouching hands-and-knees position along the very edge of the bed, her simmering face moving over her grandfather's excited lap.
Sticking her pink tongue out, she used her controlling hand to drag his bloated cocktip across her soft lingual muscle, the bitter taste of the pre-cum thrilling her. She ran her tongue along his head until it was glistening wet, then took it into her mouth, making Grandpa moan uncontrollably.
"UUuuhhhh....Lisa...ooohhh, darling....uuuuummmmm!"
Lisa had never sucked a cock as larger as Grandpa Jack's, having only been with boys her age up to that night. The size and maturity of the cock now in her mouth made her giddy, like she was giving her very first blowjob all over again. She nursed on the fat head, tonguing it as her lips pursed themselves around the underside of his glans.
Oh, Lord, forgive me! Jack prayed as his hands clenched giant bunches of Lisa's bedspread. He closed his eyes in pleasure as his sexy granddaughter shoved her mouth down on his cock, filling her mouth completely, his cocktip pressing against the portal to her very throat!
She bobbed up and down on his cock, sucking on half of his long length while continuing to fondle his balls. He closed his eyes, running his fingers through Lisa's luxurious hair. The sensations that her lips and tongue were creating on his manhood was indescribable; not because she was particularly adept but because she was young and his own flesh and blood!
After five wonderful minutes, Lisa slid his cock out of her mouth, and starting running the tip of her tongue up and down his shaft. He swept her hair away so he could watch her work, watched the way she made love to his cock. Then she took portions of his balls into her mouth briefly, sucking lightly on them. She then sat up and started rubbing his cock across her breasts.
