Chapter 3. Still at the cabin
Amy and Thomas walked hand in hand from the lake to the cabin. Their parents were nowhere to be seen so the close contact they thought went unnoticed. However their father, Brian was fucking Jennifer doggy style and witnessed their actions through the bedroom window.
Jennifer, after the panties incident in her daughters bedroom, was confident her children had become more than brother and sister. So when Brian lifted her to a kneeling position and gestured her to look outside, she wasn't surprised at their intimacy.
His cock buried deep inside his wife from behind, Brian whispered in her ear. "Should we stop? They're nearly here." Jennifer took hold of her husbands arms and lifted his hands to her breasts, reaching down she began furiously massaging her clitoris.
"Not until we cum darling!" Jennifer panted.
Brian clutched her large breasts, sandwiching her nipples between his fingers and kissing her neck as he renewed his pounding with vigour. Jennifer watched her children draw closer to the cabin. As they walked out of sight near the front door she dropped back down to her hands and knees, continuing to masturbate her clit. Brian lost hold of his wife's breasts, instead gaining a firm grip on her hips and pulling her back onto each thrust with force.
The slapping of his groin against her large buttocks echoed around the small room. The bedhead knocked against the wall beneath the window. The mattress springs squeaked with every movement. To Amy and Thomas, now standing outside the door to their parents room, the sound of sex was unmistakable.
"You know what they're doing don't you?!" Thomas whispered to Amy.
"Do you think I'm an idiot? Of course I know what they're doing!" She whispered back. Amy leaned her back against the door and closed her eyes momentarily, imagining the position her parents were in. She got it wrong, in her minds eye she saw her mother on her back and her father's cock plunging in and out of her. No matter the inaccuracy, the thought turned her on.
"What should we do?" Thomas again whispered, breaking into her fantasy. Amy opened her eyes and looked at her brother. Bare chested, water from their swim still glistening on his skin.
"Kiss me Thomas!" She commanded and her brother followed his order with gusto, meeting her awaiting lips with his. Their tongues entwined, saliva mingling. Thomas caressed his sisters arm then her breast through her bikini, her nipple hardening under the touch. Amy rubbed the front of Thomas' shorts, his erection returning.
Brian pulled out of his wife and turned her onto her back. As if channeling Amy's fantasy he knelt between Jennifer's splayed legs and rubbed his hard cock over her slickened labia. Jennifer grasped at her breasts and worked on her nipples as her husband found her clitoris with the head of his penis and stimulated her, flicking his cock back and forth, up and down on the small button. "Oh yes, yes, yes baby. Fuck me now!" She pleaded and Brian slid his length into his wife, falling atop her. Jennifer moaned loudly and Brian placed a hand over her mouth, the other grabbing hold of her fleshy butt cheek as he began furiously fucking her missionary style.
Amy had pulled Thomas' cock from his pants and was slowly stroking him as he kissed her mouth. She heard the moan from behind the door as Thomas began kissing his way down her neck between her breasts and across her belly. She'd now lost hold of his cock as he unbuttoned her denim shorts and pulled them down her legs. She knew what was coming and bent her knees slightly, bowing her legs to give her brother access to her pussy. He pulled aside her white bikini bottom, wet from the swim, now wetter from the incest and kissed her pubic bone and then the hood over her clitoris. With one hand she stroked the back of her brother's shaved head, the other she pinched the nipple of her left breast.
Brian's hand was firmly clasped over his wife's mouth as he rammed his cock in and out of her dripping pussy. His chest pressed against Jennifer's breasts, their bodies lathered in sweat. Brian and Jennifer were on the verge of cumming. Initiating the tried and true process, Brian moved a fingertip to his wife's anus and tested the lubrication. Finding it sufficient he slid his index finger deep into Jennifer's steaming asshole and uncovered her mouth. Now able to vocalize her ecstasy, Jennifer groaned with pleasure as the double penetration caused her vaginal walls to quiver, clasping Brian's cock harder with each thrust. She held her breath and closed her eyes as the orgasm swept over her body. The flooding of fluid in her vagina the pinpricks of light behind her eyelids, the twitching of her anus around her husbands finger, the explosion of pleasure in her mind. And then Brian was cumming with her. She felt each spurt of his love inside her, filling her uterus with his broiling seed.
Amy was on the cusp of ejaculation as well. Thomas was in the process of expertly sucking her clitoris, whilst fingering her vagina with two fingers and Amy wondered how this could possibly be his first time eating out a girl. The thought was swept away however by her encroaching orgasm. She held the back of her brother's head with both hands and pulled his face into her crotch. Thomas removed his fingers as his sister used his face to grind her pussy upon. His nose, lips, cheeks slathered in her juices as he was reduced to merely a sex toy for his sister's pleasure. Thomas took hold of his cock and with barely a few strokes began cumming as Amy came on his face, her body shivering and her legs nearly collapsing her on top of him.
Noise of movement from inside their parents bedroom hastened Thomas and Amy into action. Thomas used a paper towel to quickly wipe up his cum from the floor and Amy fumbled her way back into her shorts with post orgasm shaking hands. When their mom and dad exited the room, also fully clothed they found Thomas and Amy seated innocently on the couch, butter not melting in their mouths.
Amy had showered and changed into her pyjamas and after dinner, sat with the family playing board games. Like old times, Thomas cheated, yet still managed to lose and Brian swept the pool in most of the games they played. After an intense game of Clue, Jennifer pulled out the photo albums and a shoe box of old family photos.
