Sirius couldn't help the shudder that ran through his body as he felt Remus' lips against his ear, heard his words, felt his breath. He was already so close, but he wasn't letting go for fear of what that would mean. He didn't want to finish in Remus' hands because that made this real. Reality and fantasy, the lines couldn't be blurred. Still, it was okay to make Remus finish--at least it was in Sirius' head. He wasn't sure why, it didn't make sense, but it made him feel better. He opened his mouth to speak, but all that came out was a loud moan, his hips pressing forward. Rolling off Remus so he was on his side, he dragged Remus with him so he could better see him. Hoping to distract him, he pressed forward so their hips connected, devouring his mouth in a hungry kiss and beginning to tug at Remus' boxers. It never processed that his actions could be interpreted as wanting to take this as far as possible, all that Sirius was thinking about was making this alright.
Jerking them down, he didn't bother to wait for a confirmation as he purposely pushed Remus' hands away in order to grip him instead. Sighing against his mouth, he bit down at Remus' lower lip. He didn't restrain himself because he didn't have to. Pumping his hand, he swiped his thumb over the head of Remus' cock, groaning at the sensation as he began to lose all sense of self and instead gave into the feelings shooting through him.
