AN: Hello, everyone! Evangelion took over and ruined my life, if you were wondering. I wrote this little drabble for a friend of mine, Vivi, also known as Squalo or Variabitches on Tumblr. This is the first smut I've ever written, so hopefully I did okay.
Disclaimer: Obviously, if I owned Neon Genesis Evangelion, Kaworu and Shinji would've done the fricky frack.
"I-I want to show you how much you mean to me," The shorter said as he pressed their mouths together, licking at pale lips, which quickly opened up for him. Kaworu's mouth was hot and lovely, and if he didn't need to breathe, Shinji was sure he kiss him forever, tasting him, and memorizing every part of his mouth.
After they finally parted for air, Kaworu smiled in his soft angelic way, "There is no need, Shinji-kun. I'm perfectly happy just being near you, you don't owe me."
"But, you always focus just on me, so I want to do something for you," A tan hand placed itself on the hardness between the angel's legs, rubbing slightly, causing a moan. "L-let me take care of this for you."
"T-that's really nothing for you to-"
Shinji cut him off, " I want to!" Blue eyes flashed in determination. "P-please let me do this for you, Kaworu-kun."
Kaworu nodded shyly, unsure of himself, "I-if it makes you happy."
"You make me happy," Shinji tugged down Kawou's pants and underwear, freeing his erection. He stared at it for a moment, it was bigger than his own, which he supposed was to be expected, Kaworu was superior in every other way, too. He couldn't help but smile, though, because he was the only one that got to see this, the only one to see such a wonderful creation in a such a state, and the only one that was allowed to do things like this with him.
Shinji, cautiously, shyly, licked the tip, before taking it into his mouth. Sucking and licking, he moved up and down, stroking the parts he couldn't reach with his hand.
White hands dug themselves into the pilot's dark hair, pulling and yanking involuntarily."Ah! Shinji-kun! Shinji-kun!" Kaworu cried out, repeating his lover's name over and over again, like a manta.
Every cry and every yank felt better the the highest of praise, and if he could, Shinji would have smiled widely. Instead he sped up, causing Kaworu to thrust into his mouth.
Kaworu came with a whimper, spilling himself into Shinji's mouth. The taste was less than pleasant, but it was Kaworu's and therefor Shinji drank it all.
"You're truly incredible, Shinji-kun!"
"It's only because I'm always thinking about you, Kaworu-kun."
