"Remus, dar-ah-ling, we simply must stop meeting like this." Sirius pronounced, flicking his wrist in time with the extra emphasis on some words.
"You walked in on me in the shower." Muttered Remus, who was not as annoyed as he should have been if say, Peter had walked in.
"Like I said, I enjoy the occasion, none the less" Remus blushed. "but it isn't exactly –how would you say- not risqué." Flaunted Sirius.
"Why are you talking like that?"
"It's the drag get up talking, honey bun, not me." Winked Sirius. "By the way, do you have any moisturiser? These heels are giving my feet blisters."
"What about yours?" Asked Remus.
"I don't own such a thing!" Sirius acted as if he was mortally offended, and as if he didn't own mango scented hand cream.
"We all know about your secret stash of women's beauty products." Remus rolled his eyes.
"I ran out somehow. I had barely used it, I think James might be using it to molest himself." Brushed away Sirius. "And besides, if I used mine, I wouldn't be able to smell like you."
And with that, Sirius went very red in the face, tripped over his high heels and sprinted out the door.
Little did he know, Remus was the moisturiser thief, he would rub it into his hands and wrists so he could smell or rather smell like Sirius anytime he wanted.
Remus and Sirius -BAM!- instant sexual tension. Only comparable to what James and Lily share along with Irene Adler and Sherlock Holmes.
It's just science, really.
