1. Severus/Regulus
They were sitting under the birch tree behind the school, sound asleep to the beats of each other's hearts. The clock had just hit midnight and Sirius rolled out of bed to take a walk in the moonlight. Severus slowly woke up, still curled up in the arms of his lover. He kissed Regulus's chin and started falling asleep again, when Sirius came out from the path they had taken that morning. He laughed, that's what woke them. He didn't get mad and shout, he just laughed. And he kept laughing, trying to speak.
"Reg-Regulus?" his eyes started to water from laughing, trying to stop to catch his breath. "Severus, really? Looks like that and you pick /Severus/?" he laughed again and stumbled into the forest past them. Severus's eyes watered up and he looked into Regulus's eyes.
"I'm sorry, Reg…"he hugged him tight and whimpered.
"Don't be sorry, Sevvy. You're amazing." He gave him a reassuring smile. "He's all talk, anyway. He's probably just jealous of what we have." He leaned down and gave him a tender kiss on the lips. "He can't keep a girl for a week."
