Chapter Text
Sirius glared over at James and Regulus, who were leant against each other on one of the gryffidor sofas. Regulus had been about to fall asleep there, but seeing his brother's face, decided to have some fun.
He twisted so that his lips were brushing James ear and began whispering.
"Want to mess with my brother?"
James turned to face him with a grin and nodded. Out of the corner of his eye, Regulus could see Sirius already having an aneurysm. Honestly, Regulus had expected it to take longer.
Regulus may have been a petty person. He would admit that about himself, to a select few people. And when Sirius was trying to object to Regulus having friends of his own?
Regulus smiled, and leant up quickly to kiss James on the cheek.
"Will you come with me and help me with…” he paused, and bit his lip very carefully, glancing down as obviously as he could without seeming suspicious. “…something, Potter?" Regulus asked, loud enough to be heard by Sirius.
James stared down at Regulus, seeming slightly confused. However it was very clear to Regulus when James realised what he was planning. He could almost see the tiny click of cogs as James realised, and a tiny oh fell from his mouth. James' eyes slipped down Regulus for a moment, before he he gave his most devilish grin.
"Of course. I do love.. helping you, Black."
Perfect, Regulus thought. James had understood exactly what he was going for. And, Regulus realised as he glanced over at Sirius, it was working perfectly. The elder black brother was red in the face and clearly fighting with himself.
When Regulus pulled James out of his seat and began leading him towards the portrait hole, he was already smirking with victory. 3...2…1-
"Stop!" Sirius shrieked. Regulus spun around, quickly fixing his face to a neutral expression. He raised a casual questioning eyebrow at Sirius.
"You two are not allowed to- to- to mess around with each other like this." Regulus had to try very hard not to laugh at the outrage on Sirius face.
"And why not?" James asked. The gryffindor pulled Regulus hand into his and glared at Sirius, the picture of gentlemanly outrage.
"Because- because you're my best friend, and he's my brother." Sirius' voice got significantly higher with each word, till Regulus was desperate to shut him up.
Regulus tuned to James and raised one eyebrow. James gave an almost imperceptible nod in return. The almost wordless communication the duo had as best friends came in very useful sometimes.
Regulus gave a cold smirk to Sirius, before turning and kissing James Potter full on the lips.
James gave a gentle gasp against Regulus' cold lips. And then he was kissing back, kissing him breathless. One of Regulus' hands found it's way into James' hair and he ran his hand through it almost frantically. James leant closer against him and his mouth opened and then-
"Enough!" Yelled Sirius. Regulus pulled away to look at him.
He looked positively traumatised. "Fine. I get it, you do what you want. Just- please do it away from me.” He begged.
A minute ago, Regulus would have been extremely happy with what Sirius had just said. However, a lot could happen in a minute (a lot meaning a long and frankly brilliant kiss with James Potter) and all Regulus wanted now was to talk to- or kiss- James for a while. His heart thudded as he sucked in a giddy breath.
Oh merlin, Regulus thought as he realised the truth. He had a very large crush on James Potter. However, that could be processed later. For now, he needed to accept the perfect opportunity that had been offered to him by Sirius.
"I'll gladly do…. it.…. away from you." Regulus responded.
He pulled James out of the portrait hole, not even needing to look back to see Sirius' utterly horrified face.
