Sirius ghosted his lips over Regulus's neck, making the younger boy pant under his breath. The Slytherin wrapped his arms around his brother's neck, pulling down Sirius's head closer to his neck.
"More," he moaned. "Please."
"Hmm," Sirius hummed as he bit down on the conjunction between Regulus's shoulder and neck. "Call me big brother."
"Big brother, please."
Sirius chuckled as he switched their positions, pinning the Slytherin against the wall, and brought his lips up to Regulus's ear. "Mother and Father would have a fit if they knew about it."
Regulus clawed at Sirius's back as the older teen bit down on his earlobe. "S-Screw them."
"How bad of you, little brother." Sirius's lips hovered over Regulus's. "It's… arousing."
Regulus blushed, but bunched his fingers in the Gryffindor's long hair. "Shut up and kiss me."
