Luke twisted a curl on top of his head as he laid on his stomach, kicking his feet like a teenage girl, as he watched 50 Shades of Grey. He was curious as to what all of his friends thought the hype was about and like any other hormonal teen boy he decided to watch it. He couldn't help but bite his lip at the thought of Calum tying him up like that. How hot would it be if Cal-
"Luke, bub I'm home!" Calum called out as he entered the empty house, well empty besides himself and now his stepbrother.
Luke didn't seem to hear as he continued watching.
"Luke I-" Calum stopped mid-stride into Luke's pastel purple bedroom as he noticed what exactly the boy was watching.
His eyes trailed down Luke's back as he watched his long legs kick in the air, not missing the way his little stepbrother's skirt rode up and exposed a peek of his lace panties. Cal gulped hard as he felt his hands twitch with the need to just grab the boy's plump ass. Luke was quite the sexy twink at 16 while he himself was 19.
Luke felt the odd sensation of being watched so he turned around, gasping and slamming his laptop shut, "Cal! I didn't hear you come in."
"So you're really watching that shit?" Calum laughed in a condescending matter.
"I-I was just-"
"You were just what? Do you really think that's how it works, well baby boy you're sadly mistaken."
Luke's eyes widened as he sat back on his heels on his bed, staring up at his step brother that was now standing in front of him.
"It's not?"
"Far from it, but you're too young to know," Calum sighed, Luke missing the teasing smirk.
"Am not! I'm a big boy Cal please I wanna know!" Luke whined as his hands pulled at Calum's plain black tee.
"You're a big boy? Wow that does seem to change things," Calum said with a face of deep thought, even though he was just teasing the poor boy.
"I've been told I give good blowjobs Cally, just tell me how to make it kinkier."
Calum nearly choked on the air he was breathing when he heard those words leave his little brother's mouth.
"You what?" Cal growled, grabbing Luke's hair and pulling him up onto his knees.
The young blonde gasped as his eyes close tightly, hands flying up to wrap around Calum's wrist.
"I'm sorry! I thought it'd make you treat me like a big boy I'm sorry!"
Cal chuckled as bent down so his face was level with Luke's, "a big boy? I'll treat you like one alright, but you'll always be my little boy."
