You were the baby boy of James F Potter and Regulus A Black, they were both boyfriend in Hogwarts and they both are 16 years old and you were 4 months old.

Right now you were laying on your back on James and Regulus' bed in their shared dorm, Remus and Sirius were there too and Peter was not here since he was searching snacks for the night.

Sirius was in his animagus form, a black dog and he was nuzzling your neck with his snout, making you giggle as Regulus smile and James chuckle, Remus was shaking his head with a grin. Remus and Sirius were a couple too.

Sirius keep nuzzling your neck or cheek or stomach, making you giggle, he loved being your uncle and he loved you, his nephew.
