Part 2

Sebastian awoke to a beam of golden sunlight peeking through his blinds. The 28 year old stallion was pleasantly surprised as he remembered what the previous night had entailed. He was face to face with his sleeping 10 year old son Bobby. Their legs still locked and the both of them snuggling together completely naked. Sebastian's morning wood twitched as it was snugly squished between their chests. His flare was just inches from the boy's chin, which was a surprisingly silly sight. 
Yawning, he smiled and rubbed Bobby's back. It might be a taboo, but he didn't care about that anymore. Bobby had filled the void in his heart and now he couldn't think of anything better than sharing his life with the boy. Perhaps it was the glimmer in his eye that he got from his mother that attracted him. Maybe it was the boy's unconditional love. Whatever the true reason for him to have fallen in love with his son one thing was for certain, he was eager to teach Bobby what it would mean to truly be lovers. 

Bobby yawned, opening his eyes to see his dad. Smiling, he remembered what they had done before falling asleep.
"Morning dad," Bobby said softly. His gaze dipped down to see the stallion's shaft pulsing between them. 
"Hehe, looks like you're starting the morning the way I normally do."

Sebastian smirked, thinking back to how rock hard the boy was the previous morning. Leaning forward he gently kissed the boy's lips and reached between them to fondle him.
"Morning kiddo, you wanna be hard like your daddy? That's an easy fix." 

Bobby closed his eyes while Sebastian rubbed him. Quickly the boy's 10 inches grew out of his body and rubbed up against his dad's 20 inch monster. Giggling as Sebastian released his hand, he returned a kiss back to the stallion. 
"Thanks Dad," he replied feeling the warmth of his father's mature cock against his boyhood. 

Reaching up and caressing the boy's cheek, Sebastian gazed lovingly into Bobby's eyes.
"You're very welcome, kiddo. What do you say we take a shower and clean off last night's adventures. Then maybe some pancakes?" The boy's face lit up with excitement and he nodded. 
"After that I was thinking about showing you how stallions can mate…Since you're daddy's boyfriend now." 
Bobby's smile grew wide and he nodded again with even more enthusiasm. Sebastian ran his right hand through the boy's thin mane. He had completely fallen for his son in just a single night, and knew Bobby would be more than willing to get even more intimate with him. It had been ages since the older stallion last made love. Despite never considering mating with another male, let alone one as young as his son, Sebastian was extremely excited. He also knew that once he took Bobby's virginity, that the young horse would want to have sex more often. 

Getting out of bed, the two walked hand in hand to the bathroom. Their dicks flopped back and forth as they walked, keeping them both rock hard. A rush of water echoed through the house as the shower warmed. They took turns revealing their bladders, and stepped into the steamy cascade. The two of them each took their own stream of water, but mostly remained facing one another as they cleaned the dried cum from their bodies. Sebastian took some time washing Bobby's back, and then crouched down so the boy could do the same to him. Both teetered between fully and semi erect the entire time. 

The older stallion instructed his son to wash his boyhood and butt thoroughly. Bobby had a slight understanding of what was to come after Sebastian's explanation of the birds and the bees the previous night. Any boy his age also had a rudimentary idea of putting one's dick into a hole. The specific mechanics though still eluded him slightly. As he washed himself he couldn't help but feel a deep sense of joy. His dad had accepted him and seemed to want his body as much as he wanted his dad's. 

"Looks good kiddo," Sebastian said, lightly smacking Bobby's rear. "Why don't you towel off."

Bobby yelped in surprise, but quickly nodded in response. "Ok, dad." Stepping out of the shower and closing the door, the boy grabbed his towel off of the rail and rubbed himself dry. 

Sebastian watched as Bobby spent an extra minute drying his dick and massaging his young balls. The sight caused the stallion to involuntarily lick his lips as he rinsed the last of the shampoo from his mane. As he stepped out of the water, Sebastian got his son's attention as he headed for the door.
"Hey kiddo," he said, causing the boy to turn. "Just toss on an old t-shirt. No need for pants or underwear today." Bobby smiled and nodded, then headed for his room. 
Sebastian toweled off and snagged his robe from his bedroom before heading to the kitchen. Like Bobby, he wanted only to loosely cover his body to avoid any mess from breakfast. He had no intention for either of them to get dressed for the day. There wasn't much reason to if they were just going to rip everything off again.

To the kitchen they went, and just as promised Sebastian cooked up a pile of pancakes for them both. Bobby had on a worn out sports jersey which Sebastian had given him to sleep in a few years back. The long fabric reached almost down to the boy's knees. It was perfect to hide his dick so that they both could relax to eat without being further aroused. By the time the pancakes came off the griddle both of them had fallen flaccid again. 

After several fluffy flapjacks and a quick rinse of the dishes, the two returned to the master bedroom with haste. Closing the door behind them, Sebastian lifted Bobby up under his arms and placed him down on the bed so that they were face to face. Placing both hands on the young stallion's face, he leaned forward and kissed him. Bobby receptively parted his lips and their tongues met. 
"Mmmmm. Mmmmmmh."
Moaning into each other’s mouths, both felt themselves growing hard once again. Bobby's 10 inches caused a tent to form in the baggy shirt, while Sebastian's mature 20 inch cock poked through the barely held together the robe. As if by fate, their flared tips bounced together guarded only by the silky fabric of the shirt. Pulling from their kiss, Bobby giggled and looked down. His dad's long cock twitched, oozing precum onto the fabric which quickly soaked through meeting his boyhood. 

Pulling the string of the robe, Sebastian let it fall to the floor. He then reached under Bobby's shirt and pulled it up over the boy's head. Tossing it over his shoulder, Sebastian reached down and grasped Bobby's length with both hands. He took a step forward and pressed the boy's cock against his own. 
"Ah!" Bobby gasped, his boyhood now rubbing against his father's. "D…dad."

"Just relax, kiddo," He replied, raising his right hand and rubbing the boy's cheek. "You're so cute, you know that?" Sebastian knew if he didn't take things slow, he might overwhelm him. This was their first time together after all. Neither of them had ever been with another stallion like this. He also wanted to be sure he wasn't just going to use Bobby to fill his own desires. He loved him dearly and wanted to be sure the boy got to cum at least once before he did. 

As he rubbed their long equine cocks together, Sebastian began planning his next move. He wondered what it might be like to have Bobby penetrate him. He never thought much of anal play before, but he also wanted to fully become one with his new boyfriend. Knowing full well precum wouldn't be enough at first, he understood exactly what he needed to do. Though he had been on the receiving end of a blowjob before, this would be the first time he gave one. Not wanting to seem uneasy however, Sebastian did his best to ease his nerves for the sake of giving Bobby a good time. 
Taking a deep breath, he released his hand from their dicks and crouched down. His cock rested on the edge of the bed, keeping it posted up at an angle. Now face to face with the boy's package, Sebastian cupped one hand under Bobby's balls and looked up at him.
"Ok kiddo, I'm gonna get you ready. Feel free to hold onto my head if you find it hard to stay standing."

"Ready for wh…AH!" Bobby gasped as he watched the older equine's tongue lap across the lower half of his boyhood. "Oh, dad!" Instantly he grabbed Sebastian's mane and watched carefully as his father used his mouth to pleasure him. 

Thinking about what he always enjoyed having done to himself, Sebastian figured Bobby would enjoy the same treatment. He began with a few long licks from the center of the boy's sack up to the central ring on his cock. Using the full width of his tongue he teased the lower half of the shaft to slowly build up the pleasure. To the older equine's surprise, Bobby's gasps and moans really turned him on. The taste of the boy's cock was also quite pleasant, which only encouraged him to keep going. Carefully rolling his son's balls around with his left hand, Sebastian lifted his head up slightly, gleefully licking from the middle of the shaft to just beneath the flare. Bobby bit his lower lip from the rise in pleasure. Feeling his dad's tongue tease the edge of his flare sent waves of intense pleasure through his body. It was so much greater than the mutual handjob from the night before, and he loved every second of it.

SLUUUURP 
"How you doing, kiddo?" Sebastian asked, licking up the precum dripping down from the tip. 

"G…good. Really good!" Bobby gasped, his voice sounding satisfied. His knees wobbled as he struggled to remain standing. 

Sebastian smiled, feeling a mix of pride and satisfaction. His own cock twitched periodically, shooting short streams of precum onto the bed between Bobby's feet. 
"That's good," he replied. Releasing the boy's balls he then raised both hands and rested them on Bobby's hips. Leaning back in the older equine licked in one long stroke from the bottom of the boy's sack and up the shaft. As he reached the flare, Sebastian dropped his head, taking the tip into his muzzle and gently sucking on it. Immediately Bobby let out a loud yelp. Smiling over the pulsing boyhood, the stallion sucked a bit more on the flare. Once again Sebastian was surprised at how great the taste was. His son's sweet boy juices began flowing more and more, fueling his desire. 

After a few seconds of focusing on the tip, Sebastian took a deep breath and dropped his head further. Seeing the shock and awe on Bobby's face gave him all the confidence he needed. Knowing he was far too inexperienced to even attempt deepthroating, Sebastian still found himself able to get about half of Bobby's 10 inches into his mouth. As he grew more comfortable sucking on another male's cock for the first time, he worked his head up and down gently. 
"Mmmm. Mmmmmm. Hmmmmm." 

Bobby's grip had by this time tightened. The feeling of being blown by his dad was unlike anything he thought was even possible. Having a constant warmth on his boyhood was better than he could have ever imagined. Sebastian slurped loudly as his head bobbed up and down a bit faster. The older equine could feel his son's flare rubbing against the back of his mouth. Remembering to breathe through his nose, he grew more confident as time went on. Pulling on and off of the boy, he periodically lapped beneath Bobby's flare, coating every part of the tip in his saliva. 

After a minute or so of pleasuring the boy, Sebastian pulled his head off and sat back admiring his work. Now dripping with a mixture of precum and saliva, he could tell there was plenty of lubricating liquid for penetration. 
"Ok kiddo, looks like you're ready," he said, brushing the boy's hands off of his mane. The panting young equine watched as his father climbed up onto the bed and laid back. The stallion's cock flopped back against his chest, twitching periodically. Lifting his legs slightly he nervously presented his backside to the boy.
"Come here kiddo."

Bobby nodded and crawled over so that he was kneeling between Sebastian's legs. Though he wasn't explicitly told to do so, his instincts seemed to guide his body. His throbbing boyhood leaked a long stream of precum down the length of his shaft as his gaze was focused on the stallion's puckering entrance. 
"In…inside?" Bobby asked, already imagining what was coming next.

"Yep," Sebastian nodded. "Push it in nice and slow." He couldn't believe this was happening. Inviting his son to penetrate his tailhole for the first time was exhilarating. His heart pounded heavily as the boy aligned his stiffness. Unsure of what it was going to feel like, the stallion took a deep breath just as Bobby pushed his flare inside. 
The two shared a simultaneous gasp followed by a short moan. Slowly the younger equine pushed his boyhood further and further until he hilted against his father. Sebastian could feel the distinct edges of his son's cock slide deep into his body. The flared head rolled against his prostate sending shivers up his spine. The older equine's cock flexed in response, shooting a large splash of precum up over his head, which coated the bed's headboard. 

"Ah, d…Dad!" Bobby gasped as the last of his 10 inches disappeared inside. The pubescent horse was now balls deep and loving every second of it. Sebastian's tailhole squeezed around the entire length tightly. His warm insides perfectly fit the entire shaft. 
Sebastian nearly fainted from the unbelievable pleasure which coursed through his veins. Being filled by another male felt amazing, and he wished he had tried it sooner. Having his first gay experience also being with his son made it even better. He could feel the boy practically rubbing against his own mature cock from the inside. He could feel every pulse, twitch, and throb of Bobby and it was absolutely bliss. 
As much as he wanted the boy to just hold his cock in one place, he knew that wouldn't be enough to bring either of them to climax. 

"When you feel ready for it, start thrusting in and out. Ok?"

"O…ok," Bobby replied, eyes fixated on their point of connection. The experience of the initial penetration gave him a mixture of intense pleasure and awe. Being inside another horse felt incredible and it was almost too much for the boy to process. Bracing his hands against Sebastian's thighs, he pulled back his hips, sliding his boyhood ¾ of the way out. The pull back sent a new spike of pleasure through his loins which was quickly followed by an even greater one as he plunged right back in. 
"Oh wow!" He gasped, feeling the full cycle. Instantly he repeated the motion and found himself speeding up instinctually. 

Sebastian smiled as he watched Bobby's face light up with joy as he learned just how good sex felt. In turn, he found himself beginning to moan louder and louder the faster his son pounded him. Every time he felt the 10 year old's flare rub against his prostate, a wave of intense pleasure shot through his body. With Bobby now moderately pumping in and out, every thrust was one more reason for loving him. 

PLAP PLAP PLAP PLAP PLAP 

The two panted and moaned heavily. Their shared pleasure fueled their bodies' natural hormones, as they became one for the first time. Looking lovingly into each other’s eyes, they didn't have to say a word to communicate just how much they were in love. Reaching his arms up over Bobby's shoulders, Sebastian pulled the boy down and kissed him. This was the most perfect day in such a long time. He had completely submitted to his young son's desires, and had truly become his lover. The thought of what they had become completely filled the void which had lingered in his heart since the passing of the boy's mother. 

PLAP PLAP PLAP PLAP PLAP PLAP 

"Oh yes, Bobby!" Sebastian grunted. "Keep it up! Pound daddy with that big boy cock!" 

"Ah, ah, Dad!" Bobby gasped, his rhythmic thrusts turning harder. "I…I love you so much! I'm…I’m gonna…" 

"Yeah fill me up! Pump daddy full of your hot cum!" 

"Ah…AHHHHHH!" Bobby's hips jolted forward one last time as his cock throbbed wildly. Buried all the way inside the stallion, his body shivered as he released his load. 

Sebastian, feeling the first stream of his son's hot seed splash inside his body, lifted his legs and wrapped them around the boy's back. The sensation of being filled was very strange, but he loved every moment of it. As the pressure built inside of him, the older equine felt his own orgasm commence. 
"Oh, this is the beeeest!" Sebastian shouted, his tailhole clamping tightly around Bobby. His mature cock pulsed, shooting ropes of cum across his chest and splashing under his chin. It was pure ecstasy for them both! 

The stench of sweat and cum filled the air as their explosive climaxes tapered off. They looked deep into each other’s eyes, breathing heavily with their jaws hung wide. They were now more than just father and son. They were lovers. The excitement of their forbidden feelings for each other gave them both a sense of satisfaction from what they had just done. 
Glancing down at the older equine, Bobby giggled as he saw the streams of Sebastian's cum rolling from his chest and onto the sheets. 
"Wow Dad, you sure made a mess." 

"I…ah…I couldn't help it. It just felt so good." Letting his legs relax back onto the bed, he sighed a breath of relief. "You can pull out now kiddo."

"Oh, right ," Bobby had already forgotten he was still balls deep in the older equine. His shrinking cock slid out followed by a loud POP as his flare pulled past the sphincter. Instantly Sebastian clenched to avoid losing any of the boy's precious cum. He wanted to be sure he held it inside as long as he could. Collapsing forward onto Sebastian's chest in exhaustion, Bobby's young form pressed against his father's slowly shrinking cock. Reaching up, Sebastian wrapped both arms around him and snuggled the boy up to his face. He smiled and gently kissed him, as he stroked Bobby's thin mane. 

"So how do you like mating, kiddo?"

"Mmmm," Bobby hummed, wiggling his hips. "It was amazing. I love you so much, Dad."

"I love you too, kiddo. You wanna go again?"

"Huh, like right now?" Bobby asked, pushing himself up and looking surprised.

"Well…as soon as you feel up to it. It usually takes a few minutes to get hard again afterwards. Just let me know when you're ready." 

"O…ok…just let me rest a little." 
Bobby smiled and relaxed back on Sebastian's chest. Closing his eyes he took his time thinking about how things had changed in such a short time. Becoming his dad's boyfriend was the best thing to ever happen to him. Not only that, but he had just mated for the first time in his life and was welcome to continue doing so for the rest of the day. The joy he felt was almost indescribable. 

Sebastian too was overjoyed. As he caressed the resting boy, he smiled feeling the pubescent cum churning in his belly. The older equine would end up bottoming for the 10 year old another 5 times over the course of the day. Each load of Bobby's hot boy-cum hit inside him harder than the last, until he could barely keep the ample supply of it contained. If it was possible for him to be pregnant as a male, he easily would be.

The day came to a close with another long shower and several batches of laundry. It was back to school for the young equine tomorrow and work for Sebastian. Though the butterflies in their chests wanted to mate everyday, both knew the weekend would bring ample time for their next time. Returning to their separate bedrooms for the week ahead, the two shared one last passionate kiss before the night came to a close. Watching the naked boy walk out of the room, Sebastian laid back on the clean sheets with a wide grin across his face. For the first time in ages he felt complete. His son had become his lover and life was perfect!
