Remus tried not too look, he really tried but he could not help himself and he did spot Sirius' cock. He, of course, did not think that could be because of him so he felt jealous of what ever girl his friend's body had reacted too. He knew he had no right to be jealous but he was and the wolf was even more jealous. It took all the power he had not to grow and to smile.
He did look down quickly when he realized that he was still openly staring at his best friend. Merlin, his friend was so very beautiful. He blushed as he wondered if Sirius' skin would feel as nice to the touch as it looked.
He held out his friend's clothes and tried to look as normal as possible, smile as normal as he could and hopefully he would not find out what thoughts were going through the young wolf's mind.
