Why is it just impossible for us?

*time skip after the final battle of Sasuke and Naruto"
After Sasuke got back in Konoha, he got locked in a room of course, but that didn't stop Naruto to visit him. He always fed Sasuke, told him about his days, talked about their future. And people in Konoha already started gossiping about Sasuke and Naruto because they were always together, even though Sasuke was locked up. Some Naruto fangirls were jealous and always tried to keep Naruto away from going to visit Sasuke, yet again Sasuke understood that there could never be something between them. It was always impossible.
When Sasuke finally got out from "jail", him and Naruto got more close . They went to Ichiraku together, they hung out together, they went on missions together. And on one mission they had together, they started talking about their relationship, turns out the feelings were mutual even though they knew Konoha would absolutely be against it. One day, (at the mission) they sat in the forest and started talking again"Looks like it's just impossible teme.. " sighed Naruto. "I don't really care about the others. I just want to be with you.. But you're right. It's impossible for us. "The moon light hit naruto's gorgeous blonde hair and blue eyes, while Sasuke just admired his beauty and couldn't hold back. He grabbed Naruto closer to him, their faces inches away like that one time, and once again they shared a wonderfull kiss under moonlight, suddenly it turned into a quite aggressive kissing, Sasuke started touching Naruto's body a little and then said " I know it's impossible for us. But at least once.. Let's do it once in our lives Naruto..For the last time. " Naruto closed his eyes and kissed Sasuke himself. Sasuke started touching Naruto more till he toke his and Naruto's clothes off and and thrusted in Naruto while he moaned, but both Sasuke and Naruto enjoyed this wonderful moment. After they finished, they cuddled and kissed, knowing this was for the last time.
