Daddy's Birthday Present CFNM

The morning had started with Cassie waking up her stepdad Derek by blowing a blue and pink party streamer. Derek was startled awake by the whistle, then immediately soothed by Cassie's giggle.

"Morning, Daddy!" She laughed. "Happy birthday!" Her giggle was infectious.

Derek lay under his white sheets and stretched, his shirtless, hairy chest arching as he did. His middle aged body was in decent shape, a little thick around the middle, hairy with a balding head, but he had a greying beard and near perfect health otherwise.

Cassie, his twenty one year old stepdaughter stood there still giggling.

Derek flinched, noticing his morning wood. He hoped Cassie didn't see it, but judging by her laugh she very well could have.

"I made you breakfast, Daddy." She smiled, pushing back her long blonde hair. "I also got you a birthday present."

Derek sat up, moving his legs so they hid his boner. "Let me get dressed and I'll be right down, Sweetheart."

"Okay," she chirped, nearly skipping out of the room.

Dreke got up and got dressed, putting on his black work suit, white shirt, and the red and blue pinstriped tie Cassie had given him this past Christmas. He zipped his pants, his boner pressed against the fly. He patted his cock, willing it to go down. If this were any other day he would have jerked off in bed this morning to alleviate his problem, but not today.

At the table in the dining room, Casie had laid out a smorgasbord of food. Waffles with whipped cream, maple syrup, berries, and sprinkles, oatmeal, orange juice, coffee, toast and eggs, sausages and ham. Derek's eyes lit up when he saw it.

"You did all this for me, Sweetheart?" He asked, humbled. "Thank you!" He pulled her to his side and kissed her cheek.

She giggled. "Of course, Daddy! Now eat up so you can unwrap your present."

Derek sat and ate to his heart's content. Big bites of waffles and meat, washed down with orange juice and coffee. Cassie sat next to him, smiling as she ate, too.

When they were done, Cassie couldn't contain herself anymore and pulled out a rainbow polka dotted gift bag. "For you, Daddy. Open it!"

"Okay, Sweetheart." Derek took the bag, rummaging through the pink tissue paper inside. He grabbed something and pulled it out. His eyes instantly widened.

"Well, what do you think?" Cassie asked excitedly.

"Its a dildo." Derek said in a slight shock. "I don't mean to be ungrateful, Sweetheart, but why a big, pink, sparkly dildo?"

"Well, the doctor said you were having prostate trouble, and I read online that dildos are good for the prostate. I thought it'd help." The earnest and endearing look on her face made Derek weak. She was a sweet girl. Loving and kind, thoughtful to a fault. Her big blue eyes blinked at him.

"Oh, Sweetheart," Derek searched for the words to say. He felt embarrassed and uncertain of what to do. "I--"

Cassie shook her head. "I knew you wouldn't like it," her smile dropped to a frown, her eyes began to water. "It was a stupid, strupid present." She hung her head shamefully, her lip quivering as she faught back tears.

"Oh, no, Honey! Sweetheart! I love it!" Derek knelt to the ground to comfort her, the pink glittery cock still in his grasp as he pet her head. "I love it! I do! I promise, Sweetheart."

"Yeah?" She instantly perked up. "Good! You should try it out!" She reached in the bag and pulled out a bottle of lube.

Dereks eyes widened and his stomach sank, the sweet and salty foods in his guts feeling heavy as cement."I don't know, Sweetheart." He stood up. But before he knew it, Cassie had unbuckled his pants and dropped them to his knees, his fresh white briefs exposed to her.

"Cone on, Daddy!" She yanked his briefs down, exposing his limp dick and fat balls, all in a nest of grey and brown pubic hair.

Derek instinctively covered his exposed genitals with both hands, the dildo still tight in his grip.

"Please," Cassie looked up at him, batting her pretty eyes. They were still wet with the tears from before. "For me?"

Derek couldn't say no. It was impossible. He went to open his mouth but before he could say anything Cassie interrupted.

"Hurray! Thank you, Daddy! You'll love it, I promise!" She spun him around and bent him over, his hairy ass sticking right in her face. She smiled as she took the dildo and lubed up the pink toy before she pressed the end against his hole.

Derek winced and made a whining sound he had never made before as the thing slowly entered him. He gripped the table tight as she pushed it deeper inside him.

"Easy, Daddy," Cassie said gently, as if he were a wild animal she was trying to sooth. She smiled, watching his hairy hole open and accept the fake dong, it was over halfway in now.

"Cassie," Derek began to buckle and his breath caught in his throat. His ass felt full and incredible. It was overwhelming. "Sweetheart, please, I--"

Cassie ignored him, sliding the toy dick in and out of his hole slowly. "Easy, Daddy." She purred. "That's a good daddy. Just relax and take it."

Derek lay flat on his stomach, his arms to either side of his head, gripping the opposite edge of the table. The food and plates lay to the side of him, the smell of breakfast was intoxicating.

Cassie started to pick up speed, deeper in she went with the toy, causing Derek's leg to shake.

Derek moaned into the table. "Please, Honey. My ass. Please, oh fuck! My ass!" He whimpered. "It feels so good, Sweetheart." He was drooling on the table, his lips moving and kissing the wood frantically as pleasure filled his hole. He reached back and grabbed his hard cock. A veiny, precum-slick man-rod. It felt so good to stroke it as his stepdaughter filled his ass up tight.

The dildo had become more rhythmic, sliding in and out with steady easy.

"Oh, Cassie," Derek whispered, the pleasure of his hole overwhelming him. "Please, Sweetheart."

Cassie flipped Derek over on his back. Derek looked down at her in a daze. She was wearing the dildo on a harness now. It was a strap-on she had pulled out of the gift bag. Derek pulled his legs up in awe as she slid inside him again, fucking his hairy little hole.

"Isn't this fun, Daddy!" Cassie giggled.

Derek wrapped his arms underneath his thighs, still jerking his cock.

She smiled and laughed at the sight of him stroking his dick. "You're so silly, Daddy."

"Yes, Sweetheart, Daddy is very silly." Derek whimpered as she slammed into his sweaty ass cheeks, the dildo going all the way in.

"Let's go faster!" Cassie giggled, jackhammering as fast as she could into Derek's virgin ass.

Derek yelped, holding on to his cock for dear life as his stepdaughter fucked him, causing the table to shake, a few plates falling to the floor in the process. Derek was sweating through his shirt and jacket. He hurriedly pulled them off, leaving his tie.

Cassie grabbed his tie, pulling it as she railed him in the ass. "Keep jerking your cock, Daddy. I wanna see you jack off!" She giggled.

"Yes, Sweetheart!" Derek could never say no to Cassie, but in this moment he felt totally at her mercy.

Cassie pulled the dildo out of his ass, causing him to coo with pleasure. She held the greasy pink dong up next to his as he stroked. "Wow, Daddy. This is about two inches bigger than yours. How big is your dick, Daddy?"

Derek kept stroking his cock as she measured it against the toy. "Um, six and a half inches."

She giggled, cramming the dildo back up his hole, pounding away.

Derek felt stupid, he could barely think with this dildo fucking his ass. He was splattering precum like mad and he couldn't stop jerking off.

Without warning, Cassie pulled him to the floor. Face down and ass up as she began to fuck him more. Derek moaned into the cool tile floors that felt good on his sweaty, warm skin.

"That feel good, Daddy?" Cassie smiled, proud of helping her stepdad with his prostate health.

Derek groaned into the tile. It must've sounded funny because Cassie laughed.

Cassie maneuvered him so his legs hung over his head and his cock hung over his face. She pogo-sticked the dildo in and out of his hole, looking down at him as she fucked him. "Come on, Daddy, keep stroking your cock."

"Yes, Sweetheart." Derek's mouth hung open in a pleasure stupor. Precum rain down on his face and in his mouth. He was stroking his dick straight at his face. He was so aroused, he could cum at any moment.

Cassie looked down at him, pushing her beautiful hair out of her face. She gave one too-forceful bounce with the dildo and Derek popped, he moaned loud as he shot hot cum all over his face and in his mouth, moaning and collapsing as he dif.

Derek lied on the floor, his face covered in his own cum.

"Eat it up, Daddy." Cassie giggled. Derek did as she said, swallowing his cum and licking it off his face and fingers.

"Oh!" Cassie stood up quick and perky, popping the dildo from his ass. "I almost forgot your birthday cake!"

Caassie went to the kitchen and brought bake a white sheet cake with rainbow letters and sprinkles that said, "Happy Birthday, Daddy!" She set it on the table and stuck the back end of the dildo in the center so it stood straight up.

Following her instructions, Derek got on the table and squatted over the cake, sliding the dildo back up his sore and hungry asshole. He bounced up and down on it, stroking his sore cock.

"Happy birthday dear Daddy," Cassie sang.

Derek jerked fast, moving up and down on the dong. His mouth hung open, some cum still caking his beard.

"Happy birthday to you," Cassie giggled as she sang, the sight of what her stepdad was doing made her smile. "Stroke your dick and fuck your own hole, just like I want you to!"

Cassie picked up a white frosted cupcake covered in rainbow sprinkles and lit the tiny pink candle on top of it. She showed it to Derek with a grin on her face before holding it out in front of his cock. "Now make a wish and blow out your candle."

Derek bounced up and down, fucking himself and jerking fast like an idiot."Hhhhha! Sweetheart! Fuck! Please! Please, Honey! My ass! Oh God, my cock! My cock and my ass!"

"Think real hard, Daddy," she giggled. "Is that you're wish? To feel like this everyday?"

Derek nodded profusely, bouncing on the dildo as deep as he could, his ass and balls splattering in the cake beneath him, stoking his hard, red dick like his life depends on it.

"Then blow out your candle, Daddy," Cassie chirped excitedly.

Derek nodded, stroking his cock. "Oh, fuck! Sweetheart, oh fuck! Uhhhhhhnguh!" Derek's growling bellow became a pleasure-soaked whimper as he shot three wads of cum on his cupcake, snuffing out the candle.

"Yay!" Cassie clapped and jumped. She gingerly removed the candle before handing Derek the cupcake. "Just for you, Daddy."

Squatting on the dildo, his ass in the sheet cake, Derek took the birthday cupcake he came on and ate it while his stepdaughter watched.

"Happy birthday, Daddy." Cassie smiled.
