Sirius laughed as he pushed Regulus up against the bookshelves in the library of their parent's house. It was the summer of Sirius's fourth year at Hogwarts and his mother had demanded the two boys dust and clean the library.
"Reggie that tickles!" Sirius laughed again, a deep bark, as Regulus took the feather duster and ran it under the older boy's chin.
"That's the point!" Reggie darted out from under Sirius' arms.
Sirius grabbed Reggie and pulled him hard against his chest, both of them were breathing a little heavier, "you are covered in dust," Sirius smiled and place warm dry lips against his brother's forehead.
"C'mon Sirius, not here, mum will come in and kill us." Regulus pulled away, eyes darting from his handsome brother to the closed door.
"Yeah but it's half the fun, remember when she made us clean out the pantry," eyes dancing Sirius wrapped muscled arms around Regulus's thin chest.
"Yeah and the ummmm….. Ice Mice," Regulus tried to gulp air, but it was always hard to breath around his brother. Sirius kissed the boy's chin, finger tips tapping out a rhythm on Reggie's chest.
"Or the garden? Weeding it sure took longer than ole mum expected." Sirius stepped away, took his dust rag out and began to sweep dust off the shelves.
Regulus mouth went dry watching Sirius's hips swing back and forth. "Ummmm I'd never imagine those long grasses could hurt so much or feel so bloody great!"
Sirius turned around, "just think about how dirty we could get in here!" He advanced towards his brother both boys smiling the same smile, eyes twinkling in the same heated and excited way when the door slammed open.
They turned quickly to see Bella and Cissy in the doorway, they were embracing, lips locked together. Seeing they were not alone they froze. Four pairs of eyes darting every which way, each of them knowing they'd been caught doing something naughty.
"Ummm is Aunt here then, where is Andromeda?" Regulus broke the silence.
"Yes, needed a family recipe, oh, she's out and about I guess," Narcissa bit her lip.
Sirius took Regulus's hand and began to pull them out of the room, each knew they'd never speak of this, but as a parting shot, being Sirius and all he whispered, "try the bookshelves they're really comfortable!"
