Sebastian lay awake staring up at the cold white ceiling. The 28 year old widower stallion and father of a 10 year old boy sighed. Having a kid with his high school sweetheart was never part of his plan, but life is funny that way. They were both so young and naive. He thought back to his dreams of a well paying career, and how quickly that became derailed. Then came the accident. His life was just so different than how he imagined it would be. Yet he wasn't totally unhappy. His son Bobby was the shining beacon in his daily life. The young stallion was the spitting image of him in his younger days, and a near perfect physical specimen. 

"Dad?"

Sebastian rolled to the side to see Bobby standing in his open doorway. The boy was missing his familiar white briefs and was dragging a blanket behind him. This wasn't totally uncommon. Despite going to bed with his pajamas on, he always seemed to wind up naked by morning. It was like that ever since he was little. 

"What's up?"

"I can't sleep. Can I stay with you tonight?"

Sebastian smiled and rolled over away from him. "Sure kiddo, come snuggle up behind me." 

Bobby smiled and walked over to the bed. Wrapping the blanket around his waist, he lifted the covers and nestled in behind his dad. The two would lay together a few times a month, so Sebastian was used to it. For Bobby, it was comforting to fall asleep hugging his dad from behind. For Sebastian it gave him a sense of companionship in the absence of his late wife. It wouldn't take long before both of them would fall asleep together. Sebastian closed his eyes and relaxed into his son's warmth, letting his regrets fade away.

… …

A ray of sun enveloped Sebastian the following morning. It was Saturday, which meant he got to sleep in. As he wiggled a little he remembered Bobby had fallen asleep with him last night. Smiling, he lifted the covers and looked down. Sebastian froze. He expected to see both his son's hands wrapped around his chest, but instead the boy's right was firmly cupped much lower. Luckily he didn't have morning wood, but his sizable equine package nestled within his boxer briefs was being squeezed by the sleeping boy. 

"Bobby?" He asked, seeing if his son was conscious. He wasn’t, thankfully. Gulping, Sebastian reached to Bobby's wrist and attempted to pull his hand off. Despite his best efforts, the boy wasn't letting go…at least not without waking up. 
"You're kidding me," he mumbled to himself. "Alright calm down. Just don't get hard and everything will be…eh!?" It was too late. Now that he realized that he was being touched, his body reacted as it always did. Boxer-briefs growing tight, his mature adult shaft telescoped up and out of the waistband. To his surprise, Bobby's left hand lifted from his chest and gently laid down on his manhood. Sebastian didn't know what to do. He knew he should stop it, but he hadn't felt another equine touch him in years. Considering that Bobby was doing all of this in his sleep, somehow made him feel less guilty. Still though, he knew he had to try and pull him away again. Wrapping both hands in his blankets he rolled to the side and lifted Bobby up and away from his body. Almost throwing the boy against his headboard, he pushed himself up against the wall and covered his erection as Bobby finally woke. 

"Mrmph," Bobby grumbled, opening his eyes. He rolled around a bit, then sat up and yawned. "Morning dad."

M..morning kiddo," Sebastian's eyes were fixated on the naked boy. The 9 year old (like him) was rock hard! His boyhood stood tall at 10 inches, an impressive size for an equine his age. Stallions were big regardless, but Sebastian could tell his son was considerably larger than average. The boy didn't seem to be bothered by his stiffness, and just crawled out of bed taking his blanket with him. Sebastian watched as the boy barely said a word as he slowly wandered back to his room. 

Just as Bobby turned the corner and Sebastian heard the boy's bedroom door shut, he flung off his covers and darted to his own door. Closing and locking it, he breathed a sigh of relief. After a few seconds he looked down at his still throbbing erection with disgust. 
"What the fuck is wrong with you," he whispered. "He's your son!" 
Continuing to stare at himself he slowly let his hands reach up. Easing his boxer-briefs down off his hips. He let them fall to the floor and stepped out of the leg holes. Now freed from his tight, restrictive bindings, he let his 20 inch cock fully grow and his heavy balls hang low. Placing his hands right where Bobby's were just moments earlier, he closed his eyes and let out a long breath. 
"But it felt so gooooood," he thought. Starting to rub himself, the stallion began thinking about his son's soft innocent hands on his body. 
"Ah, stop it!" Again he pulled his hands away. Reaching for his bathrobe, he covered himself and tied it tight, keeping his cock pressed up against his chest. Quickly grabbing a fresh change of clothes he made his way to the bathroom between his and Bobby's bedrooms. Thinking a shower would calm his morning wood, he shut the door behind him and turned on the water. As it warmed up he could hear Bobby rustling about in his room and again his mind wandered. 
"I wonder if he started jerking off yet?" 

SLAP
Smacking himself across the face, he pulled his robe off and got into the shower. Their shared shower was a double wide stall, with 3 different shower heads cascading down from the ceiling. It was a considerable luxury for someone as young as Sebastian, but his connections with a friend in construction gave him an opportunity for the upgrade. As the water washed over him and steamed up the glass door of the shower stall, he felt his manhood begin to shrink. 
"Ahhh," he sighed and he began to mull over his chores for the day. 

Just as his dick had finally receded into his body, he heard the bathroom door swing open. 
"Oh, sorry Dad. Just brushing my teeth," Bobby said, making his way to the sink. 

Sebastian didn't think much of it. Sharing the space with his son often warranted them being separated by the glass. It would have been a simple in and out procedure if Sebastian hadn't accidentally brushed his tail across the glass though. The slight clearing of the glass, gave him a perfect view of Bobby…he was STILL NAKED! Instantly the older equine's flaccid cock, peaked back out and grew into a semi as his gaze was fixated on the boy's dick. His mouth hung open and his tongue flopped out as he candidly watched the innocent boy. As Bobby spit the last of the frothy toothpaste into the sink, and moved to turn around, Sebastian quickly looked away and faced the wall. He listened as his son walked out of the bathroom and closed the door behind himself. With a deep sigh of relief Sebastian looked down to his semi with a grimace.
"Come on, get it together."

Calming himself down again, he finished his shower and got dressed. Returning briefly to his bedroom, he opted to switch into a jockstrap to keep his package tight and restricted in case of any other surprises. The last thing he wanted was for his innocent son to see him hard. 

The rest of the day was fairly uneventful. He cooked breakfast and a light lunch for them. While Bobby remained in his room playing video games most of the day, Sebastian worked around the house on a handful of diy projects. As the day came and went Sebastian had nearly forgotten about the unusual morning he had. It seemed all would be fine until that evening when everything he thought about his own sexuality and restraint would change. 

… …

Saturday evenings once a month we're pizza and movie night. A large deluxe pie was ordered from their favorite shop down the road, for this month's event. The two changed into looser fitting clothes just before sitting down with their paper plates. Side by side on the couch, the movie started as they chowed down. 
Several greasy slices and half an hour later, Bobby had snuggled under Sebastian's right arm. The strength and warmth of his father made him feel safe and secure. They remained that way for the rest of the movie, barely moving at all except for the occasional laughs. 

By the time the movie had ended, Sebastian noticed Bobby had fallen asleep. Turning the TV off just as the credits rolled, he yawned and looked down at him. His gaze froze as he saw a tent in the boy's shorts. Though he was asleep, it seemed one part of him was still up. The loose fitting silky shorts left very little up to Sebastian's imagination. He could actually see the outline of the boy's flair through the fabric. 

"Bobby?" He whispered, nudging him. "You up?" It was a silly question. Bobby was such a heavy sleeper after all. Biting his lips, Sebastian suddenly felt the need to free his son's erection from the shorts. Loose though the fabric was, he imagined it was still a nuisance to the sleeping boy. With his right arm still holding Bobby close, he reached his hand down to the waistband. Pulling the tied drawstring until the knot popped loose, Sebastian's heart pounded heavily. With the shorts now loosened, he slowly pulled the front of the waistband up until there was enough room to push them over the young equine's boyhood. 

BOING

The stiffness flopped back and forth, standing proudly up from his body. Sebastian's jaw dropped at the sight of his son's body.
"Wow! He's so much bigger than I was!" He whispered. 
"No wonder he can't keep his clothes on at night." He wasn’t really thinking straight by this point. He hadn’t seen Bobby's dick since he last changed his diaper years earlier, and for some reason seeing how much he had grown filled him with a sense of pride. Not to mention how healthy and virile he was. Before he even realized he had gone so far, his right hand had grasped Bobby's length and he started stroking up and down gently. He wasn’t sure what came over him, but the same sense of pride seemed to compel him to see if the boy could ejaculate yet too.

As Sebastian casually gave his son what he assumed was his first handjob, he could feel his own dick slowly rising to the occasion. Though his jockstrap kept his arousal at bay for a little while, he quickly found himself yanking his own shorts down and letting himself harden. His balls still held within the jock, his mature equine cock pulsed as he continued working on Bobby's length. 
"Oh geez, what are you doing?" He thought to himself. "This isn't the kind of bonding you're supposed to do with your kid…but I…I just can't stop." 

"Ah, yeah!" Bobby moaned, his eyes remaining closed.
Instantly Sebastian stopped and pulled his hand away. He wasn’t sure if Bobby was still asleep or…
"Huh?" Bobby lifted his head and opened his eyes. Looking up at his dad he had a confused look about him. "Why'd you stop? That felt really good?"

"What the!?" Sebastian leapt away from him, pulling his legs up his chest to try and hide his obvious erection. He was terrified. His son had just caught him, but…the boy wasn't bothered by it? "H…how long were you awake?" 

"I was never asleep," Bobby replied. "Did you think I was?"

Sebastian was completely at a loss for words. He didn't know what to think. Not only did he get caught touching his 10 year old son, but it seemed the boy actually wanted it. 
"B…Bobby…I…"

"Whoa!" Bobby gasped. "I knew you were bigger than me, but I didn't think it was THAT big!" Scooting closer Bobby pulled one of his dad's legs down getting a clear view of his adult dick. "Hehe, did you like it when I played with you this morning?"

Sebastian suddenly snapped back to reality and began scolding him. "What's wrong with you!? That was not ok!"

"But…but…" Bobby quickly grew upset.

"No buts! You can't just touch me…or anyone else like that. Damn it Bobby, you're only 10!" 

"But I love you, Dad…" Bobby said as tears welled up in his eyes. "Aren't you supposed to do that with other horses you love?"

"Where did you hear that!?"

"I dunno, everyone at school says that…and…baaaaa!" He could no longer hold back his tears and he let out a long wail. Instantly Sebastian backpedaled his stern attitude, seeing how upset Bobby was.

"Ugh, I'm sorry Bobby," Sebastian said, sounding resigned. "I guess we should have had this talk by now. 

Eventually Bobby managed to calm down, as Sebastian began explaining the world of love and sex to him. Both slowly fell flaccid again, but left their shorts off for the sake of comfort. As Sebastian explained, touching feels remarkably good, but there is always a time and place for it. He also explained the taboo of incest and how Bobby being so young made things complicated at best. While he understood, the boy was still disappointed.

"So…Does that mean I can't sleep in your bed anymore?"

Sebastian sighed. "As long as you keep your hands to yourself, then you can still stay with me." He was pleased to see Bobby finally smile again. With the conversation coming to a close, he scooped Bobby up in his arms and took him upstairs. They were both tired and despite needing to clean up, Sebastian decided it would be a problem for tomorrow. 

Careful easing Bobby down onto the mattress, he watched as the boy pulled off his t-shirt and discarded it on the floor. Pulling off his own, the now naked older horse snuggled up beside his bare son. It may not be the most welcomed sight if anyone had caught them like that, but perhaps that was a perk to being a single dad. 

… …

Once again Sebastian couldn't sleep. Despite his best efforts, the very act of sleeping naked with Bobby was now bothering him. He thought back to how much the boy wanted to be in a physical relationship with him, even though he knew how wrong that was. Yet…for some reason he couldn't stop thinking about what that would be like. He hadn’t felt like this since his wedding night, and it was a little exciting. Of course they already loved each other as any parent and child would, but this…this would be taking a very different step into the taboo. Yet he still found himself looking over to the sleeping boy with a longing in his heart. 

"So what if he's your son? So what if he's only a kid?" He thought. "He wanted you…and you wanted him. You love him. He's your everything."
As the night stretched on, Sebastian rolled to one side facing Bobby. He watched the gentle rise and fall of his chest as he was this time actually asleep. He looked so peaceful. Despite his reservations his mind was now made up, and there was no turning back. 
"Ok, then," he whispered, feeling his dick twitch just from looking up and down the boy's body. "No one has to know but us." Gently pushing on Bobby's shoulder, he called his name, awakening him. 

"Uh? Is it morning already," Bobby grumbled rubbing his eyes. 

"Kiddo?" 

"Yeah? What's up?" Bobby blinked a few times, his eyes adjusting to the room, dimly lit by the moonlight. 

"Remember what I told you about why we shouldn't be intimate?"

"Yeah?" Bobby yawned. 

"If you promise never to tell anyone," Sebastian reached his hand across the boy's groin and cupped his package. "Then we can. If you still want to, that is."

Bobby immediately jolted the rest of the way awake and sat up. "Wait, you mean it!? But I thought you didn't want to."

Sebastian resigned the last of his doubts and smiled. Reaching up with both hands, he cupped them under Bobby's cheeks causing him to blush. 
"I love you Bobby." Then closing his eyes Sebastian leaned in and gently kissed his son on the lips.

"I…I love you too, Dad." Bobby wasn't sure exactly what to do, but he had seen enough movies to have a general idea. Opening his mouth slightly, he pressed his lips back to his dad's letting the older equine slip his tongue inside. It was a strange, but pleasant feeling. He felt his dad's tongue press against his own, guiding it back and forth between their lips. 

"Mmmmmmh. Hrmmm. Mmmmm. Mwah," Sebastian pulled his head back and looked at Bobby whoseface was flush. He smiled at the boy's reaction and a rush of instant happiness and pleasure filled his mind. Certain that he was his son's first kiss, he waited patiently for the boy to respond. 

"Ah, dad." Bobby replied with a soft moan. "I'm…uh…" 
Sebastian looked down to see a tent forming in the sheets. The older equine chuckled lightly and reached beneath the sheets grasping Bobby's growing boyhood. The young horse gasped as his father gripped it tight and flung back the sheets with his other hand. 

"You're really big for your age, you know that?"

Bobby giggled and leaned his head up kissing Sebastian gently. "Hehe, Not as big as you though." 

"Ha, you wanna take a closer look at your daddy's cock?" 

"Mmmhmm," Bobby nodded eagerly. 

Sebastian smiled again. He was rock hard by this point and eager to show off his manhood to the curious boy. Flinging the remaining sheets onto the floor, he spread his legs wide giving the boy a clear view of his adult cock and heavy balls. Bobby's eyes lit up as he stared in awe of his father's impressive package. Though he briefly saw it earlier in the night, this was the view he longed for. 
"Like what you see," Sebastian asked. Bobby nodded and he grabbed the boy's hand raising it to grasp his manhood. His tiny fingers could barely reach halfway around the thick shaft. "Rub mine like I'm rubbing yours," he instructed. 

Looking like some strange before and after picture, they laid side by side stroking each other's cocks and moaning. Neither could believe what was happening, but were both now enjoying themselves too much to care. Sebastian was shocked just how amazing Bobby's young hand felt. It was better than any woman, EVER. In turn Bobby bit his lip as his boyhood quivered with delight. The young equine had certainly touched himself by now, but there was something about his dad's mature grip that was driving him wild. 

Though he was rather inexperienced, the boy's hand was more than enough to bring the older equine up to the edge. Having been  without anyone to pleasure him for several years, Sebastian had become extremely sensitive. He knew it wouldn't be long before he would burst. Bobby as well found himself quickly reaching the point of no return. As his dad's hand pleasured every part of his 10 inches. As he felt the sensation rise, he realized his dad must be nearly there himself. The older equine began rubbing the very tip of Bobby's boyhood, coaxing out a few drops of precum. Mimicking his movements, Bobby rubbed his palm in circles around the flair of Sebastian's cock. 

"Ah, ffffaaa, Bobby I'm gonna, c…CUM!" Sebastian shouted, bucking his hip into the air and squeezing his son's warm cock tightly. 
The quick pinch was all the young equine needed to join his father in an explosive orgasm. His hips jolted upward and a blast of warm boy juices shot into the air. The two took turns involuntarily thrusting their hips as ropes of cum sprayed over their bodies, the bed, and the ceiling. Sebastian by now could feel the cum shooting from his son's cock, and couldn't feel prouder that the boy was already producing the same volume he could. His little boy was growing up faster each day. 

After what felt like an eternity, the two relaxed back into the now soaked sheets, panting heavily with eyes closed. Both were still holding the other's cock, though their grips were very loose. As they caught their breath, the two turned to see the other doing the same. Sebastian wanted to say something to encourage and reassure the boy, but his returning gaze spoke louder than words. Letting go of Bobby's shrinking boyhood, the younger equine released his hand as well. As if telepathically, Sebastian and Bobby rolled onto their sides, and wrapped their legs together. Letting their tired hands rest on the other's side, they leaned in for a final kiss. 

"Mmmmmm. Hrmmm. Mmmmm." 
The boy now knew what to do, and Sebastian submitted to his son's tongue. Returning the favor from earlier, Bobby explored the mature equine's mouth in a way he never imagined. 
"Muah!" Their gasps were loud and lustful, both sounding satisfied.

"So…how was that kiddo?" Sebastian finally managed to ask. 

"It was…amazing," Bobby gasped. "Can we do that again sometime?"

Sebastian gently kissed his forehead and smiled. "Oh, Bobby. We're gonna do that every day from now on. I love you so much."

"I love you too, Dad."

Closing their eyes, they held each other close as the clock ticked over to 1 AM. "Perhaps we'll just stay in bed tomorrow," he thought, as his member shrunk back into his body. His life wasn't what he thought it would be, but he wouldn't trade it for anything in the world now. Finally feeling relaxed, Sebastian drifted off to sleep in his son's arms.
