Sibling Revelry: An 18th Birthday to Remember

Chapter One: The Birthday Surprise

David lay sprawled out on his plush four-poster bed, the early morning sunlight streaming through the window casting a warm glow on his smooth, hairless body. His nine-inch cock lay thick and heavy against his thigh, a testament to his youthful vitality.

The door to his bedroom creaked open, and TJ, his younger brother by a year, entered the room. TJ was also naked, his own body freshly shaved and just as alluring as David's. His six-inch cock stood at attention, a smaller but still impressive version of his brother's.

David grinned wickedly as TJ approached the bed, his eyes locked on his brother's cock. "Morning, little brother," he said, his voice low and husky. "Join me?"

TJ nodded, his own gaze fixed on David's body. He climbed onto the bed, laying down next to David and letting out a contented sigh. "Mmm, nice and warm," he murmured, his hand reaching out to brush against David's chest.

David chuckled, his hand moving to rest on TJ's thigh. "So, what do you want to do for your birthday?" he asked, his voice dripping with suggestion.

TJ's eyes lit up, a mischievous glint in his gaze. "I was thinking we could watch a porno movie together," he said, his hand moving to rest on David's cock.

David raised an eyebrow, a smirk tugging at his lips. "Oh really?" he said, his hand moving to cover TJ's. "And what kind of movie did you have in mind?"

TJ's cheeks flushed, but he held David's gaze. "Something…incestuous," he said, his voice barely above a whisper.

David's smirk grew wider, his hand moving to stroke TJ's cock. "I think I have just the thing," he said, getting up from the bed and heading towards his collection of adult movies.

He returned a moment later with a DVD in hand, the title "Sibling Lust" emblazoned on the cover. TJ's eyes widened as he read the title, his hand moving to stroke his cock faster.

David inserted the DVD into the player and settled back onto the bed, TJ following suit. The movie started with two brothers making out and stripping off their clothes, leaving them in their underwear. David's hand moved to rest on TJ's thigh, his eyes locked on the screen.

The brothers on the screen started jerking each other off through their underwear, their cocks straining against the fabric. David's hand moved to TJ's cock, his fingers wrapping around the hard length.

TJ moaned, his hips bucking up into David's touch. The older brother on the screen removed his underwear first, his cock springing free and glistening with precum.

David's hand moved to TJ's waistband, his fingers hooking under the fabric. "Do you want me to do the same to you?" he asked, his voice low and seductive.

TJ nodded, his breath coming in short, shallow gasps. David pulled TJ's underwear down, his cock springing free and bouncing against his stomach.

The older brother on the screen began to fuck the younger brother, their bodies moving in a rhythmic dance of pleasure. David's hand moved to TJ's entrance, his fingers circling the tight ring of muscle.

TJ moaned, his hips bucking up into David's touch. "Yes, please," he whispered, his voice barely audible.

David reached for the bottle of lube on his nightstand, his hand slicking up his cock and TJ's entrance. He slowly pushed inside, TJ's body welcoming him in with a soft moan.

Just as David was finishing up, their parents entered the room, but they were surprisingly fine with the incest. "Oh, looks like you boys are having fun," their mother said, a smirk on her face.

David pulled out of TJ, his cock still hard and glistening with cum. "We were just watching a movie," he said, his voice casual.

Their mother raised an eyebrow, her eyes flicking to the screen. "Really?" she said, a teasing note in her voice. "Well, I think it's time to get cleaned up for TJ's party. Your cousins Samantha and Jasmine will be here soon, and I'm sure they'll want to join in on the fun."

David and TJ exchanged a glance, their eyes widening. Their cousins were also bisexual and had been "doing the same thing" as the brothers.

David grinned, his hand moving to stroke TJ's cock. "I can't wait," he said, his voice dripping with suggestion.
