Lazar's commission part 1

The first commission I ever did for anyone. I hope Lazar likes it. Of course I didn't had space for all fetishes he asked, but at least I got the essencial "themes" right.

John woke up from his sleep yawning, like he did every morning. The 8 year old ferret went to wash his teeth, before going to the living room, to do one of a children's favourite pastimes: wacth morning cartoons. He did that for about one hour or so, before hearing thee other room's door opening. From it came his adoptive father, a 30 year old wolf called Carl. The adult smiled at the cub, which came to give him a nice hug in the leg. For some reason, his head was pressing against the older male's crouch; Carl then started to feel his heart beating faster, and his blood starting to concentrate towards his pubic area.
"Excuse me, mind if I go a bit to the bathroom son?"
The little ferret nodded sadly, enjoying his father's company. The adult wolf then lowered himself, kissing the cub. John giggled, and the canine smiled at his happiness. The older male then left the living room, and went to his bedroom again.
Inside it was his private bathroom, largely similar to John's except for having a shower rather than a bathtub. The wolf sat on the toilet, and took off his underwear, the only thing he was wearing at that moment. His cock was already out of the shealth, and it went fully hard a minute after being released from the underwear. He started stroking it, thinking of his little ferret cub; although he thought it was wrong, and he would never do anything to hurt his son, he couldn't help it. Not too long, he was moaning due to the friction on his pole. Unknownst to him, John was wacthing all of this throw the opening in the door*, and stroking himself. His little boy meat was obviously much smaller than his adoptive father's, and it didn't had that wide knot at the base. The cub had started to felt some desire from his father, probably the fault of wacthing some of his videos. For now, though, both males were restricted to masturbation.
John was the first to finish. Bitting his lower lip, his moans were reduced to little, almost inaudible whimpers, which his father couldn't hear. When he came, nothing came out of his young genital, aside from one or two drops. His father, on the other hand, completly emptied his balls, resulting in quite a lot of white mess. Some of it landed on the door, a drop even managed to go throw the opening*, entering the cub's eager muzzle. He loved when these accidents happened.
As soon as his father got up, he left the room, quickly returning to his usual activity.
