Oh Merlin, how Sirius wanted Remus to get him off. His hands, his lips, oh they were all so fucking appealing. He was tempted to say fuck it and just have at it but -- well, he didn't want Remus to be sick.
"You're sick" Sirius said, showing a great amount of self control that he normally never put to use. "I'm fine" he lied, "You eat" he insisted though his erection was quite obvious and given how flushed he was he could use some releief.
