At first Darren just let Sam control the kiss, going from holding Darren's face in his hands to caressing his hair and running his fingers through it. Once Darren got his bearings again, he responded with darting his tongue into Sam's mouth. Their tongues now tangled together as Darren's hands began to roam Sam's body. Feeling the hairy chest and muscled back, the long lean torso to match Sam's long legs. The tall young man had to lean over to kiss Darren, and eventually grabbed the smaller boy under the arms and lifted him up, hugging him to his chest as Darren wrapped his legs around Sam's waist. Sam held his ass in one hand to support him, as Darren's arms went around Sam's neck. Their mouths never broke contact and Darren was moaning softly as he felt his little dick harden in his swim trunks.
Sam squeezed Darren's ass and held him by the back of the neck, fully in his embrace as they kissed. Darren had never realized that a kiss could be this intimate. His crush on his step-brother quickly developed into a longing, that transformed into lust once he felt Sam's hard cock poking from under the towel against his ass. Sam slowly began to walk into his bedroom as their tongues explored each other's mouths. Darren felt himself being lowered onto the bed, Sam laying on top of him. Sam pulled away from their kiss to look at Darren's face.
"I saw you checking both Jim and I out all night," Sam surprised Darren, who had thought he'd been good about not being too obvious, "And don't think I haven't noticed you outside my bedroom windows. Did you enjoy watching me jerk off? I'm happy to let you watch – you don't have to sneak around."
And with that said, Sam rolled off Darren to his side and opened up his towel. The hard dick hiding underneath sprung out and it was huge. And now that he was seeing it up close, it looked different from all the others Darren had seen. He knew about uncut cock but had never seen one before. Sam reached down and gripped his beautiful cock and stroked down. Darren watched as the foreskin pulled back and revealed the dick hidden underneath. Then Sam ran his hand up his cock and the head of his cock disappeared. He continued this motion and Darren was enthralled, studying Sam's cock as his step brother slowly jerked himself off and moaned softly next to him.
"You like that Ren, you like being this close to me," Sam asked, looking at Darren, "Why don't you do it for me. Get to know me better."
Darren situated his body up against Sam's, the difference in their size starkly obvious as they lay side by side. Sam had to be a foot taller, and it just made Darren feel that much more submissive to his step brother. Tentatively, he reached down and Sam took his hand away to allow Darren to wrap his small hand around the fat uncut cock. It felt warm against his palm, and softer somehow than the other cocks he'd held. He pulled back the skin and watched the head of Sam's cock unveiled. He stroked and studied the beauty of it, fascinated.
After a little while, Sam lifted up his arm, giving Darren a whiff of his armpit. This drew Darren's attention away from watching Sam's cock and instead, burying his face in the armpit presented to him. He drew in beep breathes as he rutted his face around in the musky patch of hair. He continued to stroke Sam's cock as he huffed and licked at the delicious pit sweat. Before too long, Sam pulled Darren's face out of his armpit and drew him up for a kiss.
"Fuck, I can smell my scent on you," Sam said in between kisses, "That feels incredible, you are doing a good job, Ren."
Darren couldn't help but smile at the praise, before Sam shoved his tongue deep into Darren's mouth again. Darren pumped the uncut cock faster, feeling it get even harder and thicker as Sam moaned into his mouth. With his other hand, he caressed Sam's chest, feeling the coarse hair coating the firm pecs. He could feel his little dick hard and pressing against Sam's side.
Sam began to thrust his hips up to match Darren's strokes and brought his hand down to the back of Darren's head to pull him in harder to the kissing. The pumping into Darren's fist became more frantic and Sam panted into Darren's mouth. Suddenly, Sam forced Darren's head down with one hand and used the other to brush Darren's hand off his cock and take it in his own grip.
"Fuck, I'm gonna cum," Sam grunted, as he quickly guided his cock into Darren's mouth, shoving Darren down on it. He had just a moment to enjoy the feel of the soft skin of Sam's cock in his mouth, slathering it with his tongue, before Sam's cock fired out rope after rope of cum. The volume soon filled up Darren's mouth, even as he gulped it down, and some spilled out of the corners of his mouth as he tried his best to swallow all of his step brother's load.
They laid there for a moment, as Darren nursed on Sam's cock and tried to coax out all the cum with his tongue lapping against the tip of the cock in his mouth. His tongue explored under the foreskin, tasting the sweet cum trapped in the folds. Darren yelped in surprise when Sam sat up suddenly, pushing Darren not so gently off his crotch, and stood up holding his heads in his hands.
"Shit, oh fuck, what did we just do," Sam walked away from the bed and dropped down into a chair in the corner, looking over at Darren with a panicked look on his face, "Oh god, we're gonna be family. What just happened, I've never done anything like that before Ren, I'm sorry."
Wanting to comfort this distressed handsome young man, Darren got up from the bed and padded over to Sam. He knelt down at his feet and leaned into his body, pressing his face against Sam's stomach.
"We can't say anything," Sam continued, but placed his hand on the back of Darren's head, petting it, "I don't know why I did that, I mean it felt good, but.."
Sam trailed off, lost in his own thoughts. Darren pressed his lips against Sam's skin, placing light kisses across the stomach. Sam was no longer talking, but the soft noises he was making indicated he enjoyed Darren's affection. This encouraged Darren to continue, moving down to kiss Sam's hips and then kiss the inside of his thighs as Darren knelt between them.
The smell coming from Sam's balls drew Darren to them and he covered them with kisses, inhaling the scent before giving into his craving and extending his tongue to draw it across the hairy ball sack. Sam responded by spreading his legs further and scooted down in the chair, giving Darren better access. His tongue traveled from the balls to the pinch of skin between the thighs and crotch. He could now smell the musk of Sam's ass, his face moving further down and he couldn't resist pushing his face under Sam's balls and extending his tongue to get as close to Sam's hole as possible.
His efforts were rewarded as Sam lifted his legs and pulled them to his chest, offering Darren the beautiful sight of the tight asshole nestled between the furry ass cheeks. Darren didn't waste a moment and dove in, lapping and kissing at Sam's hole, pressing the tip of his tongue against it to try to taste him from the inside. Sam moaned loudly above him and placed a hand on the back of Darren's head to press him in harder. The asshole twitched around Darren's tongue as it slipped in just a little and Darren was in heaven.
"Damn you're dirty," Sam whispered, as he ground his ass against Darren's face, "This isn't your first time, is it Ren."
He allowed Darren to enjoy his ass for a few minutes, before standing up and pulling Darren to his feet too. Sam seemed to have forgotten his earlier moment of panic and spun Darren around, pushing him up against the sliding glass door. He stepped up behind Darren and pressed his chest against Darren's back, as he grabbed Darren's ass and rubbed a finger against his hole. Sam spit into his other hand and brought it down to coat his once again hard cock, before slathering Darren's asshole with the remaining saliva.
"Tell me you want this," Sam whispered into his ear, teasing Darren's asshole with the head of his cock, "I know you probably just want me to take you. But I want you to say the words."
"Please Sam, please," Darren nearly pleaded, "I need you inside me."
And then Darren felt the full weight of Sam's body press him against the cold glass, as he pushed up into him in one long slow thrust. They both moaned in unison, the one opening up to welcome the other in. This was not the more gentle moment they'd experienced earlier, Darren could sense something change in Sam. It felt to Darren more like he was being conquered, as Sam's cock entered him. And it was amazing. He pushed back to let Sam in, despite the slight pain as his asshole was stretched open to accommodate the fat cock.
Once Sam had bottomed out in Darren's bottom, he pulled out just as slowly until the tip of his cock exited, only to push back in. Long, deep, slow strokes, over and over. Sam had one hand on Darren's waist and the other pressed to the glass next to Darren's face. Sam continued this, pumping, as Darren moaned and whimpered. The pace began to quicken and Sam growled into Darren's ear before his mouth clamped on Darren's neck and bite him. Sam seemed intent on sinking his teeth into Darren as he sucked and chewed on the boy, thrusting more urgently into the loosening ass.
Darren was moaning uncontrollably as he let Sam take him. He looked out the sliding glass door that he was pressed up against, as he took the thick cock inside him. His gaze was draw to the light in the bedroom window of the house next door, Jim's bedroom. He felt a slight moment of concern, remembering standing at that same window and being able to watch Sam in his room – where they were now. But luckily, Jim wasn't there now watching.
Suddenly, Darren could feel the tingling in his balls with his own hard cock was smashed against the window as Sam fucked up into him. Between the feeling of Sam's mouth and teeth on his neck and Sam's cock now pummeling his ass, he felt more owned in that moment than he had ever felt with Randy, Chris, Steve or any of the others who had also fucked him. The pain in his hole had faded and now all he felt was pleasure, from the feel of Sam inside him and knowing how much pleasure Sam was receiving from being inside him. And as teeth bit into him even deeper and the mouth sucked on his neck even harder, Sam drove his cock as deep as it would go into Darren's pussy. And that is what made Darren's little dick spew his seed all over the glass he was pushed up against.
As he came, his asshole spasmed around Sam's fat cock and Sam pulled off his neck and threw his head back to almost howl. He slammed his cock into Darren in one final thrust before he released a load of cum. Darren could feel the heat of the cum as it travelled deep into him, flooding his ass. Sam franticly humped into Darren, attempting to drain his balls completely into the boy. His boy now.
They stayed like that for a few minutes, before Sam pulled out and plopped back down into the chair.
"Come here," Sam ordered, and Darren obeyed, kneeling once again at his feet between his legs. Sam caressed Darren's face with his hand, slipping his thumb between Darren's lips and letting the boy suck on it, "Tell me about the first time you were with a man. It's obvious I wasn't your first. Tell me everything, Ren."
And he did.
