Heat
Harry woke up feeling hot, his heat was getting to be too much. Sirius was thinking about taking the omega to the hospital if this continues.
“What do you want love?” Sirius asked his omega who was climbing his lap.
“You daddy, but not you…” Harry said blushing deeply. He was still shy as to asking for Padfoot.
“You know the rules baby boy, you want something, you ask” Sirius said grinning. He loved that his omega was this naughty, wanting him in his dog form.
“I want padfoot to fuck me” Harry said blushing deeply.
Sirius now slipped off the bed and transformed into padfoot, a giant black dog.
Harry now getting naked and on all fours he could feel his hole slicking up and was getting hard at the idea of what was to come.
Padfoot now licking the omegas hole, shoving his heavy hot tongue deep inside to get that sweet slick.
“Oh good Padfoot!” Harry moaning loudly as the dog was lapping him up without mercy, then whimpering when the tongue was as gone.
Padfoot now mounted the young omega slipping his rock hard cock into his open hole panting heavily.
Harry hissed as it was much bigger then when he was human, and he wanted it so badly to rip into him.
Padfoot furiously fucking the omega unapologetically, making Harry cum for the second time.
Harry could feel the knot form thinning what will be like to be get knocked up with this beasts pups, to have the whole world know his godfather was not just fucking him, but taking him in his animagus form.
Padfoot now cumming but still not slowing down loving the ungodly sounds coming out of his godson, who was begging for more.
“Oh god Padfoot don’t stop!” Harry cried out cumming, loving the feeling of his seed shoot inside of him.
When it was done Harry was panting heavily his fever now gone, Sirius back into his human form.
“oh… daddy I need you to fuck me now.” Harry said climbing on his godfathers lap.
“As if I can say no to you.” Sirius said grinning.
