What I'm working on right now is the longest comic I ever made.
Pup Puffs and his little brother Peaches Pup live together with their sister Perla, at a house far in the woods, away from society. Although Peach and Puffs look nearly identical, they have two different fathers. Peach and his twin sister Perla have the same father. Puffs, Peaches, and Perla live with their mother and the father of Peach and his twin sister Perla, who adopted puffs.
Their mother met puffs father when he was teaching at a public school, and they got together and had Puffs. 

Puffs father was caught doing disturbing things to puffs and was now locked away. Since then Puffs fathers’ twin brother who was a friend to Puffs mother got together with Puffs mother and had Peaches. Puffs mother refused to allow Puffs to return back to Public school, because the embarrassment Puffs father caused despite how smart Puffs was, so puffs has been home schooled since he was adopted by his new father the twin brother of Puffs biological father. Puffs teaches Peaches everything he knows, but out of fear Puffs might hurt himself or others the same way his father hurt him, so his mother has his little brother watch over him.

Puffs secretly carries out the same acts his father performed on him with his sister Perlia, and teaches her to do the same acts on him. He has a photo collection of all their activities, and Peaches is envious of his twin sister for getting so much attention from Puffs. Although Peaches knows Puffs and Perlia are pretty close and he has seen them in affectionate situations, he has never seen the photos or seen the two doing anything sexual because Puffs keeps that hidden from Peaches as well.
Perla, their mother and father have all traveled to take Perla to a TV commercial audition, they could not afford to take everyone so they have left Peaches watch over his older brother Puffs. They grow their own food and have some food delivered, so the pups don’t need to leave home.
Although Peaches was put in charge of keeping an eye on Puffs, Puffs has control over the finances since he is smart, and he gives Peaches his allowance according to the chores Peaches gets done around the house. So, Puffs gets Peaches to do everything, such as cooking and cleaning. With Perla gone, Peaches takes advantage of the situation and tries to get Puffs to get more affectionate towards him. He still has no idea why Puffs like’s his sister so much more than him, and he is constantly trying to find a way to get him to feel the same way towards him.
With Perla gone Puffs gets the urge to masturbate but is still cautious. (the script begins) Puffs looks out his cracked door at Peaches cooking dinner at the stove, He goes back into his room and closes the door enough that it’s not cracked. Puffs then pull a shoe box from under his bed with his Polaroid camera, lube, his sister’s underpants and a pile of photos. 

He goes over to the window in his room and grabs the strings to the window blinds, and wraps it around his neck he looks at a photo of his sister with a belt tied around his neck as she was in a cowgirl position.
He unzips his pants and begins to fap off to the photos  he has in one hand while letting his feet slip causing the strings to tighten around his neck. After a moment he realizes he’s slipped to far and is still slipping, the blind strings are too tight, but he is also very close to one of the hardest orgasms he has ever felt coming. He is confused as to what to do, he is getting lightheaded but is rushing to finish as hard as he can, so he can stop himself from falling even further. He misses his sister so much he wants’ to finish it but he knows he cant.
Not being able to breathe very well, and with the room starting to spin, he decides to adjust, but then he feels the orgasm coming, He faps and cums as hard as he ever could remember. He could think about how weak his legs have become, and how amazing the orgasms felt, he has blacked out.
He wets himself, and droops as losing consciousness. Peaches is still at the stove cooking when a loud Boom sound comes from Puffs room.
Peaches turns off the stove, to get a better listen. He hears nothing but silence and goes to investigate.
Peaches Opens the door and finds Puffs unconscious on the ground in a in a puddle of cum and piss.  The blinds broke off the wall. 
Peaches runs to his brother and removes the blind strings and attempt to revive him. After some amateur CPR and a bunch of crying over his brother Puffs starts breathing again. 
However, Puffs does not remember anything but the last thing he felt before he passed out. Peaches notice all the photos of his sister on the ground and picks them up before puffs has a chance to see them out.
Puffs has no memory of who he was or who anyone is. All he can recall is he felt something amazing and he wants to feel that again somehow, but he has no idea how it happened.
Peaches gets puffs into bed, gets Ice for his neck, as well as removing his wet pants. Despite not to upset his mother who had him looking after his older brother he tries everything to get Puffs memory back, while trying to still win his affection. 
Later that night he checks up on Puffs who is still resting in underpants. 
He brings Puffs the dinner he was cooking on a bed tray and shows Puffs family photos and explaining everything.
In an old photo book from Puffs dad, Peaches discover photos of the actions Puffs father did to puffs in the past by mistake. Puffs see the photos and realizes the stuff in the photos reminds him felt before he lost his memory, but it did not know why. Peaches realizes the similarities in the photos of Puffs taken by Puffs father, and the photos Puffs had taken of his sister, and realized how he could get closer to puffs, and maybe even restore his memory.
Puffs ask to see the other photos Peaches had, and Peaches agreed since he would do anything to please his brother. Puffs did not recall any of the actions in the photos but began getting an erection.
Puffs asked about who she was, and Peaches explained. 
Peaches runs off and gets his sister's clothes seen in the photo and puts them on.
He returns to Puffs thinking he knows the way to get your memory back. TBC

My grammar is crap if anyone can help me fix it, your name can be in the credits.
