Disclaimer: slash, sex, don't like don't read
Author's note: I got this idea after reading book 5, and hearing all the clamour about Remus/Tonks. I finally got the courage to write it down. I've never written sex before, and have discovered that I am absolutely terrible at it. Please don't let that get in the way of enjoying the idea behind this little ficlet.

Merlin knows why Tonks liked him. There were a million better men than him. But she did. Remus knew this. He also knew that he really shouldn't have asked her to do this, but at the moment he couldn't quite bring himself to care.

He could have used polyjuice on someone, but this was much easier.

Tonks had morphed into someone else. Into him. Exactly how Remus remembered him.

Except the eyes: the expression was Tonks. But Remus could overlook that detail.

He leaned into Tonks' shoulder, and inhaled the scent that was almost Sirius.

Remus moaned Sirius' name as he trailed kisses down his neck. Sirius stiffened. Remus took Sirius hand in his own, and pulled him toward the bed, making quick work of their clothes.

Somewhere, in his haze Remus noted that Sirius did not look quite as aroused as he felt.

Sirius jolted at Remus' touch. He smirked, "Siri, you're so jumpy tonight," he whispered into the other man's ear. He had almost forgotten.

Sirius loosened up, and began kissing him. Remus thought he heard an whimper somewhere, but it was gone by the time they broke apart for air. Sirius was smirking in that cavalier Black way.

When they had finished, Sirius rolled over next to Remus. Remus smiled, and embraced him, resting his head the Sirius' rising, and falling chest. "I love you, Siri," he whispered. The soothing rhythm of Sirius' heartbeats put him to sleep.

Sirius, however, could not fall asleep. He watched Remus, sleeping so soundly. He looked happier than he had been in a very long time. "I love you, too," Sirius said, tears rolling down his cheeks.

The following morning, Tonks will wake as herself. Remus will be gone, and both will hate themselves for it.

I'm sorry, that was really bad. But I love the idea of Remus having Tonks become Sirius.
