Carissa crept down the dark hallway, making her way back to her bedroom after going down to the kitchen for a drink of water. Her short pink nightgown swirled softly around her thighs as she neared her bedroom door. She stepped carefully, trying to miss the squeaky floorboard that would announce her presence. Her parents were sleeping in the guest room, having arrived for a visit earlier that afternoon. As she walked quietly past their half-open door, she heard a rustling sound from within, and glanced into the room. The brightness of a full moon illuminated it. She stopped short, taken aback at first, and then very curious about what she saw. Daddy was kneeling on the bed behind her mother, who was on her hands and knees, naked bottom pressed against him. She watched in fascination as his hard, glistening cock plunged in and out of her mother. He held her hips firmly, working her wet pussy with rapid strokes. Carissa heard her mother moan softly, and saw her full breasts jerking under her body in rhythm with his fucking.
Carissa stood, mesmerized at the sight of her parent's hot sex. She felt liquid warmth gathering in her pussy, and shifted on her feet, her thighs pressing together, putting delicious pressure on her swelling pussy lips. Suddenly, daddy pulled his cock out and Carissa heard him tell her mother to turn around. She complied, and took his thick cock into her mouth, licking and sucking the sticky wetness, tasting her own cunt on him. He leaned down and began to fondle her breasts while she sucked. His big fingers pinched and tugged at her sensitive nipples, eliciting more groans from her, and even more enthusiastic sucking. Just when Carissa knew he must be nearly to cum, he pulled away from his wife again, telling her to turn back around. He reached to the bedside table and picked up a bottle of lotion. Carissa watched as he squeezed some onto his palm, and then dipped his fingers in to it. Her mother had resumed her previous position, on hands and knees, her shapely ass toward her husband. He began to rub the slippery lotion into her ass, pushing his fingers inside her tight hole, first one, then two, and finally three fingers.
"Oh my god," she heard her mother say, "my god, that's too much. Please…"
He seemed to listen to her, and took his fingers out, slipping them down between her legs, rubbing her wet cunt. She arched her back, spread her knees further apart, and groaned loudly. "Do you need to cum, you hot bitch?" her Dad asked. Carissa couldn't believe he talked to Mom that way! But his words nearly brought a moan to her own lips. Her hand slipped down, lightly caressing her naked pussy lips under the short hem of her nightie.
"Oh yes… please let me cum, honey," her mother begged.
"You can cum after you take my cock up your tight ass. How's that babe?" He said, his voice gruff with passion. She only whimpered in return, and Carissa wondered if she really didn't want to have her ass fucked, or if her actions were meant to further excite her husband. She herself sometimes acted a certain way because she knew if would make grandpa hotter for her. She watched as her Daddy grabbed his cock in one had, and Momma's hip in the other, and began to press his swollen cock head against her tight ass hole. His cock looked so huge to Carissa. She couldn't believe it would fit into that tight hole. She reached behind and began working her sticky-wet finger into her own ass, wanting to know how her mom felt. She saw the head of his cock push through, and he began to slowly press in to momma, in and out, a little deeper each time. Her mother groaned with each inward thrust. When he was fully inside her, he stopped, just letting her tight bottom stretch to accommodate his size. He reached beneath her, and began caressing her pussy. Carissa could see his finger circling her clit, rubbing her wetness. Carissa imagined she could smell the musky heat of their sex. When Carissa heard her mom began to whimper in pleasure, Daddy began fucking her ass with deep even strokes, all the while continuing his gentle massaging of her swollen clit.
Carissa leaned against the doorframe, careful to remain hidden, yet easily able to watch her parents. She worked her finger in and out of her ass for several minutes, and then began stroking her hot, wet pussy. Her other hand found its way to her breasts, rubbing her puffy nipples into hardness. She jumped, and nearly screamed, when she felt a warm hand slide around her waist.
"It's only me," Grandpa whispered. She felt his hands cup her breasts, and he peeked over her shoulder, watching her parents fucking on the bed. His hard cock pressed against her ass as they stood watching the other couple. Grandpa's fingers replaced her own in her hot cunt, and he kissed her neck and shoulder while he teased her breasts and pussy. She leaned back against him, giving herself up to the experience.
"Mmm baby," he whispered, "this is unbelievably hot. Imagine that big hard cock fucking you. Would you like that sweetie?" Carissa could only nod, as a huge hot orgasm racked her body. She turned and buried her face in Grandpa's shoulder, trying to smother her cry of passion. He watched over his shoulder as his daughter got her tight ass filled with cum, and her own orgasm slammed through her. She collapsed on the bed, her husband on top of her, his cock still buried in her ass.
Grandpa carried Carissa back to her room, gently laid her on the bed, and pushed her nightgown up above her breasts. He lowered his pajama bottoms, releasing his engorged cock, and then pushed her legs up and wide apart, opening her hot, wet cunt to his view. He moaned softly as he leaned forward, pushing his hardness inside her, feeling her heat and moisture envelop his cock. He fucked her slowly, whispering to her.
"Carissa, think how hot it would be to fuck your Daddy. How good it would feel to have his huge cock inside your pussy. Wouldn't you like that baby?" He continued. "I want you to seduce him, honey. Make him want to fuck you. Tease him until he can think of nothing else but burying his cock inside you."
The Next Day
Carissa awoke the next morning aroused all over again. Pictures of her daddy fucking mom had filled her dreams. God, all she could think of was that huge hard cock pumping her mom's pussy and ass. I need that so much, Carissa thought. Her fingers found her wet pussy, and she quickly brought herself to orgasm thinking of Daddy's cock.
She waited till she heard mom go downstairs, then peeked out of her door to see where her dad was. She could see him in the bedroom, lying on the bed in his robe, reading the paper. She picked up her towel, wrapped it around her naked body, and stepped into the hallway heading for the bathroom. The small blue towel barely covered her voluptuous body. Her breasts bulged out above the terry cloth, and if she leaned over even slightly her ass and pussy showed. As she walked by his room, she called out to him.
