Jack was not interested in girls, and until today, he never opened up to Russ about how he felt. Jack knew that when his knot popped inside Russ, their whole relationship changed. The two were now in the kitchen, naked humans with furred sheaths and balls the only changes they kept from earlier. They found bread and some sliced ham for sandwiches, and the two of them ate in silence, with Jake taking the frequent opportunity to grind his ass into Russ's sheath.
"I guess that settles why we don't double date," Russ noted after finishing his sandwich.
"I would go on a date with you or double date with you and the right girl," Jake objected.
"I think my record speaks poorly for me as well," Russ sighed.
"I really enjoyed what we did today. You can do that to me anytime, and I want you to," Jake said with meaning.
Russ reformed into the athro dog form he had earlier, and growled, "You cannot stop me from pounding my knot into you and keeping your ass sore."
Jake reached around behind Russ's back, and stroked his fur at the base of his thick tail. Russ let out a slow growl as he savored the petting, and his thick red cock emerged from his sheath. They took turns knotting each other for hours. A human Russ fell asleep with a canine anthro Jake holding him tight as his knot slowly deflated.
The boys spent a few months exploring new forms. Horse, otter, bear, donkey, snake, lizard, frog, eagle, dolphin, rabbit, and squirrel were the forms that were most enjoyed. New forms carried the need to learn how to have an orgasm while inside the other. Jake was always eager to fill his friend that he saw more as is soul mate. Russ gave as good as he got from Jake, and was content to just be with Jake in any form. Their special form, was from that first time as anthro german shepards.
Jake's father supported his son, but tolerated Russ. Russ's parents kept pushing him and trying to arrange dates with other girls. After high school graduation, Jake told Russ he would go along with finding a girl as a third member to join their duo, since his parents wanted grandchildren. Jake was firmly male in his identity, as was Russ, so having a third join made sense. Russ showed his thanks to Jake by assuming the anthro german shepard form. Russ did promise to both his parents that they would gave grandchildren.
The two found a college in the mountains that was not too expensive. The lack of scholarships meant a lot of student loans for the two for what part their parents could not cover. They knew they had to be careful, as only Jake's dad ever caught either of them in a non-human form, and that was only once. Jake wanted to leave his father with a gift, but he was away from home too much for a a dog. He found a place that would make custom blow up sex dolls, and had one made of Russ in his anthro dog form, and the two presented that to Jake's dad when Jake had finished packing his room. Russ saw the embarrassment in the face of Jake's father as he unfurled the doll with the large canine cock and knot. He hugged both of the boys. Russ blew the doll up for him, as it was Russ that Jake's father saw in anthro form.
Russ handed the life size doll to Jake's dad and smiled, "It's not quite the real thing, but you get the idea."
Jake handed a gallon jug of sex doll lube to his father, "This helps."
"I always wondered if that was truly real. First glance was a human size dog, the next was a naked Russ on the couch," Jake's dad replied. Jake's dad turned to Russ and asked, "Why a male doll?"
Russ smiled, "Because for weeks after that, you always smelled of sex. I presumed you were turned on by the thought and that got you off."
Jake's dad nodded and sought to kill the topic entirely, "Well boys, thank you." Jake's dad left the doll and lube on Jake's bed, and walked them to their cars. He shook Russ's paw and sighed, then hugged his son tightly for several minutes, before watching them drive off on their roughly four and a half hour drive to their home for the fall.
