Please read Part 1 if you want some backstory into these characters, plus I think it's a rather good story :P Everyone in this story is 18 and older.
"Good morning to you too." Eric chuckled as he leaned up on his elbows to look at the devilish vixen who had wakened him from peaceful slumber. Katie began giggling around the head of his cock, or at least best as she could with her mouth full of her brother's dick. She slipped her lips off the end of his dick and then flicked the tip with her tongue and grinned up at him.
"Mom and Dad will probably be home in a little while, so I don't want to spend the whole morning sleeping." She explained. It's not that she didn't love sleeping in Eric's arms nor that she was also exhausted after he fucked her in the backyard. And again in her bed. And her floor. That was all before he carried her to his bed to sleep the few remaining hours of the night. She was still sore, but it was a good ache and one created from treasured memories. However, their parents would be home in a few hours, so time was of the essence. Therefore...
Katie wrapped her smile back around the head of Eric's cock and started to slowly slide up and down, her lips tight a grin as watched the expression on her brother's face. It looked sublime, but she pictured the his face when she confessed that she wasn't on birth control. The range of emotions that washed over his face all at once was nothing short of priceless. She giggled again on his cock, tongue lightly flicking under the base of the head as she remembered the feeling when her big brother came in her pussy. That sensation would be saved deep in her masturbatory bank. True to Eric fashion he demanded that he 'fix it', so they would be driving to the pharmacy in the morning to pick her up some Plan B. Fortunately, it also meant that he would be able to keep cumming in her all night and morning until they did. For a girl who had been crushing on her older brother since as long as she could remember Katie's ovaries hard practically exploded with joy at the realization. Two hours and three loads shot deep within her later Katie had passed out into the most blissful sleep she could ever. However, her fairytale was over when when the sun peeked through Eric's windows and stirred Katie from dreamland and reality was here to stay. Though, temporarily she hoped.
Earlier that night the deviant siblings had tailed their parents to the annual Halloween party they never would tell them anything about; an event and ones like them that their parents had kept secret from their kids as long as the siblings could remember. Mom and Dad had attended an unusual amount of 'parents only' functions that it started to gnaw on the youngest sibling's curiosity. This Halloween Katie's curious nature aligned with a perfect opportunity to exploit her older brother's devotion to her and she convinced him to help in tailing their parents to their party to finally unravel the mystery. The secret rendezvous were revealed to be a swinger party at a nudist camp, surprising the pair and ending up giving them each a push; well more of a shove; into facing their obvious attraction to one another. The pair stripped down to infiltrate their parent's secret resort and confirmed their suspicions, but the sexual tension literally overwhelmed Katie. Eric had carried his little sister back to his car and made for home, trying to understand what had just transgressed. When they arrived Katie decided to rip the band aid off the situation and dared Eric to do what they both wanted.
As her head bobbed up and down on her brother's thick length Katie wanted... no, needed him one more time. She tasted herself on his shaft and she grinned, memories flooding back from the night before. Eric had been so gentle because it was her first time. He was so loving, always doing whatever hairbrained idea she came up and Katie loved being spoiled by the big dumb brute. Now she wanted to do something for him. She leaned up, her lips coming free from shaft as she regarded her brother's swollen dick. She reached out with one finger and poked his cock, the rigid rod bouncing back up. Perfect.
"Listen," his sister began, her tone growing serious for a moment. Eric found it a bit difficult to concentrate with Katie batting his cock around with her fingertips, but he did the best to focus. "Yesterday was... perfect. It's something I always dreamed about but never thought would happen." She admitted to him, her cheeks coloring as she poured out her feelings. Eric opened his mouth to say something, but Katie just shushed him. "Just shut up for a second, I need to get this off my chest and then you can have your way with me." She smiled down at him to which Eric's eyebrows went up and his mouth wisely closed.
"They're are going to be home soon, so we need to put a halt on what we're doing. Or at least pause." She bit her lip, eyes slowly roaming up her brother's toned body and sighed. "Definitely pause. A short pause." Eric started to nod along as he understood where she was going with this. If they were caught, they were dead. Well, he would be dead.
"I love you, Eric." She blurted out, having no other way to say it. "I know we say it all the time because we're siblings, but I mean it. I just... I feel like I am about to burst, I'm so happy. God, I'm not making any fucking sense." Katie laughed, her pale skin bright red with embarrassment. "I just love you, so fucking much big brother. Now take me, however you want. We have to wait a month until Thanksgiving to do this again, so make it count."
With that Katie lunged at him and wrapped her arms around his neck, squeezing her big brother as hard as she could on the verge of tears. Eric reached up and scratched his fingers along her back, following the arch of her spine until it drifted into her long red hair. "Katie, I love you too. And I always will. This... this won't change anything between us." He said, but quickly thought better of it. "No, I'm wrong. This will make things better between us. I'll always be yours. Always." He promised as his hand drifted back down her soft curves, finally resting on her bottom. "And we have much to talk about between now and Thanksgiving," he agreed before gripping her ass firmly, strong fingers sinking into her pale flesh as he leaned in close, lips brushing her ear. "But right now, your ass is mine." He growled the last word. He felt her perky breasts smoosh to his chest as she gasped at his words as her tall brother climbed to his knees lifting her off his lap.
Eric gave her ass a playful spank before extracting his clingy sister from his neck. Once freed he tossed her back onto his bed, hands roughly manhandling her onto her stomach. Two brutish paws gripped her hips, lifting them off the mattress as he positioned himself behind her. "And since you are now mine, this is for all the times you pinned shit on me that wasn't my fault. All the times you ran to mom whining when you didn't get your way. All the times you chucked me under the bus to dad." He told her as he worked the swollen head of his cock back and forth against his little sister's pink pussy, lubing the tip with her juices.
"Whoah, wait what.... Errriiccc... what the fuuuuuUCK!" his sister squealed as his thick cock speared her from behind, pushing deep until the head thumped against her core. "Ohmyfuckinggod!" she gasped as his fingers curled to sink into the soft flesh of her hips. Eric's large thumbs rubbed up the small of her back to settle in the dimples above her ass he always found adorable. Now they provided a thumb hold as he pulled back hard on his sister's hips, impaling her over and over again as her mind slowly melted.
Eric started slower than he'd wished; he wasn't an animal; but when he felt her tight teenage pussy had sufficient lubrication he let her have it. The tall college student shifted his knees up on his bed, spreading his little sister's legs a bit more and pitched her forward. He leaned over her back and took his hands off her waist, no longer necessary to grip her with the weight from his hips smashing against her ass with each stroke keeping her in place as he railed her from behind. One hand braced himself against his headboard and the other grabbed the back of her neck, for effect.
"You're mine, little sister." Eric growled from behind her head, his breath tickling her cheek as he hunched over her like a beast. His thighs jerked as he fucked her down into his mattress, hand on her neck opening to slip his palm through Katie's hair. With a snap it closed and grabbed a fistful of the red locks. "You always will be." He promised, kissing her cheek and then biting her shoulder before standing back up on his knees and pulling her up by her hair.
"Yes! Yes! I'm yours, Eric... Always... Fuck!!!" Katie whimpered, bucking back wildly against her big brother's cock. "Fuck Meeeeeeeee!" she wailed before gasping for breath. "Fuck me, Fuck me, Fuck me big brother," Katie chanted as she snaked a hand underneath her to rub at her clit. She knew Eric was strong, but he had her pinned and mounted before she realized what was happening. And this way he reached all the way... "Fuck! I can feel you hitting my insides... all the way.... Don't fucking stop... no no... Fuck." She groaned as her longtime protector mercilessly fucked her on his bed.
Eric knew he couldn't keep a pace like this up for long, but that wasn't the point now was it? He let go of her hair after a tug and grasped her waist firmly. He pulled Katie back up to her knees and gave her ass another spank, grinning as he watched it jiggle. A sudden spasm from her cunt snapped him back to the task as his little sister tried to squeeze his dick to pieces. "Katie! Wha... Grrrnnnnn!!" Eric growled as he ran his hands up her body, large palms cupping her perky tits from behind as he fell back down against her. He buried his face into her hair, breathing ragged as the familiar tightness growing in his loins erupted.
