First Time
 
By Dark Sewer Rat
 
One of the earliest years for Dark was that when he was just ten years of age, the boy knew what he wanted and that he just couldn't stop fondling himself whenever he was alone with his baby brother.  It made his boy cock just swell up as he looked at the little six month year old.  And so Dark would when others were out and he was alone with the little baby rat, would stand there with his pants down, his t-shirt up as he held it under his snout and would play about with his cock as he rubbed it over the little baby rat.  This is what Dark did and every time he did it, it became even natural for the boy until eventually he had started to offer more to babysit while the others went out and he would sit there naked with the baby and play with him.  Slowly he got the little one to learn how to suckle his cock just like he would when his mother would breast feed him, the boy would slowly work his cocklet up uintil it was firm and then he would slowly rub his wet foreskin over the young baby rat lips and then watched as the little baby boy would wrap his mouth about his cock and started to suck on it naturally.
 
At his age, Dark could only give the young boy his pre as the greedy little baby suckled so much on the older brother's cock, that the youngster got to know the scent of the older rat and always wanted to settle with him.  Dark's parents thought nothing of it as they left them both to it, glad to get some peace and quiet as the boy babysat the little one more, feeding the baby brother with the bottle and of course with his cocklet.  Each time he did that, his cock was just slick with the thick saliva that just oozed all over his small cock and balls and whenever Dark molested himself, he could smell the scent of his baby brother on his hand.  And so, this ent on for another half a year as the more time Dark was alone with the baby, he was busy offering his cock to the youngster.
 
To Dark, this was normal and his sexual urges for the youngster became stronger with each passing day.  Eventually, the boy tried to rub his cock up and down the young baby boy's bottom, holding the tail out fo the way as it slipped into the crack and Dark started to dry hump the baby from there.  Slowly, as he neared to his birthday, the urges continued to grow stronger, his dreams became more arousing and vivid, then Dark turned Eleven and had his first wet dream.  He laid there in the bed as he felt the white gooey substance and tasted it, the boy explored everything about it and then he just couldn't stop getting an erection.  Dark, also couldn't get the view of his naked baby brother out of his mind either and it was driving him up the wall as he waited for his parents to leave again.  By the time that they did, he was ready to explode and Dark went straight for where the little baby boy was sleeping and tok him out of the cot, quickly pulled down the flap of his onesie, pulled the diaper out of the way and looked at the cute baby butt in front of him as his cock strained in his sweatpants.
 
Quickly, Dark pulled them down as his cock sprung upwards, dripping with pre as the boy moved forwards and started to slip his cock in between the buttocks of the baby boy until he felt the inner cheeks become wet with his pre, then the boy rat found the baby anus and he swirled his cock around it for a moment, then as the baby continued to sleep, he pushed forwards.  Slowly his cock began to open up the tight virgin baby rear and popped in as the baby woke up and started to cry.  Dark reached around and clasped his hand over the small mouth of the baby, muffling the crying as he slowly sunk his penis into the tight baby, the tight hot innards gripped about his shaft and head and Dark could only gasp loudly.
 
It was there that Dark knew it was right, it felt so good as the boy rat raped the little baby brother there and then as his cock slipped in and out of the tight back passage as the baby boy cried into his hand paw.  But Dark didn't care as he wanted to feel more of his cock inside the tight back passage, so he rammed more of it inside as he hilted into the little baby, just a month shy of being one and started to fuck the little kid rat hard and fast while all the time he shook with excitement as he robbed the young brother's virginity without a care.
 
With a wet hand from the tears the baby was oozing all over him, the boy continued to thrust back and forth hard, his groin slapped against the baby bottom as he panted heavily to the wet slurps and pops his cock was making from the stretched out anus of the young baby.  Then Dark felt his penis go all funny, then tingly and before he knew it, he climaxed and spurted his boy cum deep within the bowels of his baby brother.  Dark just panted heavily as he slowly pulled out and then carefully pulled the diaper back over again, did up the back flap and offered his shit cum covered cock to the baby who sniffed it and then pulled away.  Dark frowned and he forced his cock into the mouth of his baby brother as he made the youngster suckle and clean his cock for him, then he pulled out as he sighed happily, put the pacifier into his little brother's mouth and put him back into his cot again. 
 
As the little baby was left to fall asleep with it's red sore anus, Dark made his way back to his room as he flopped onto the bed and started to wank himself as he thought about his little baby brother, and it didn't take him long to climax once more as his entire belly and chest got covered in his white cum.
