When in Doubt (Nightmare x Blue)

DNA

Blue took his time picking out the song. He scrolled past plenty of weird songs (the machine was a bit old, even though it kept downloading new songs) until he found one he'd forgotten about. He had to fight to keep control of his laughter as he chose it. Hopefully, Nightmare had never heard it before.
"Does he tell you he loves you when you least expect it?"
Dream snorted.
"Does he flutter your heart when he kisses your neck?"
Nightmare made a choking sound.
"No scientist or biology, it's obvious when he's holding me. It's only natural that I'm so affected..." Blue paused then began to sing in a bit of a higher voice. "And my heart won't beat again if I can't feel him in my veins. No need to question, I already know! It's in his DNA D-D-D-DNA it's in his DNA, and he just takes my breath away b-b-b-breath away, I feel it every day, and that's what makes a man, not hard to understand, perfect in every way, I see it in his face, nothing more to say, it's in his D-D-D-DNA~"
Dream was trying not to laugh, Error and his two lovebirds were enjoying the song, Ink looked confused, and Nightmare...Nightmare was pretty much broken.
"It's the blue in his eyes that helps you see the future...fingerprints that leave me covered for days~ Now I don't have any first degree, but I know what he does to me, it's only natural that I'm so affected...and my heart won't beat again, if I can't feel him in my veins, no need to question, I already know! It's in his DNA D-D-D-DNA, it's in his DNA, and he just takes my breath away b-b-b-breath away, and that's what makes a man, not hard to understand, perfect in every way, I see it in his face, nothing more to say, it's in his D-D-D-DNA~"
Nightmare was still broken. He didn't even know Blue listened to this kind of music. All in all, he had NOT been expecting this. That's not saying Blue's voice was bad...the guy was singing across two octaves. It was just...different.
"Something about his kiss, contaminates my lips, our energy connects, it's simple genetics, I'm the X to his Y, it's the color of his eyes, he can do no wrong, no, he don't need to try~ Made from the best, he passes all the tests, got my heart beating fast, it's cardiac arrest, he's from a different strain, that science can't explain, I guess it's how he's made, in his D-D-DNA~" Blue sang the main verse one last time and got down from the stage. The others burst into applause, except for Nightmare, who just blushed and looked away.
"Was it bad?"
"No...just...a bit suggestive..."
"How?"
"Tell you later."
