As the name of the prompt already implies this is nsfw :)

Hot

As Seto lay on his back, still panting and trembling a little he felt his eyelids becoming heavier by the second. He was so freaking tired, he just wanted to doze off and get some well deserved sleep but there was no way he could sleep like this. He forced his eyes open again and to his slight surprise looked directly in Atem's smiling face.

"You can sleep if you want. It's not like I'm not tired, too"

He just shook his head and then nodded it down to his soiled stomach, hands and the stains on the sheet. "No chance. This is just too messy for me to sleep in."

Atem tilted his head to the side and then chuckled. "Well, it's every bit your fault as it's mine."

"I know…" Was all Seto could say to this. He wasn't really used to that kind of conversation yet. Granted, this wasn't the first one they had like that, but it was still somewhat awkward with how content he felt. His first instinct was to flee the scene altogether but the way Atem was lying next to him, a smile on his face and looking just as messy as he did, took his nervousness away a little and he slowly sat up. "I might as well take a shower."

Atem propped himself up on his elbows, groaning almost like the old soul he was. "Yeah... Sounds like the right thing to do."

Seto nodded, got up as smooth as he could and waited a moment until he was sure to be steady on his feet, then turned and waited for Atem to get up as well. But the small man just rolled on his stomach and then lied there unmoving until he started to laugh and turned his head to Seto. "Jeez, what did you do to me?!"

Seto couldn't help the triumphant smirk that spread on his face as he leaned forward, picked Atem up easily and threw him over his shoulder like a potato bag. "It's called sex. And I think I did pretty well." Instead of answering him verbally, Atem actually spanked his ass and Seto chuckled darkly when he walked into the bathroom. "I take that as a yes."

He put Atem down slowly, steadied him until he was able to stand alone and then looked at the shower as if it would give him an answer on what to do next. "So... we're getting in there together?"

"I guess..." Atem still swayed a little when he took a step forward and Seto grinned widely. He really did great obviously. "I'm somewhat confused. You don't have a shower head in form of the Blue Eyes?"

"The Blue Eyes White Dragon is no water dragon." Seto shook his head, held out his arm for Atem to take it and they entered the shower together. "Why would I bring her in the shower?

"But a stream can also be of water, right? So why not?"

"It can but in case of the Blue Eyes it's not. It's a killer attack. Who would get into the shower for a killer attack?"

"Well no one goes into bed for a killer attack, too but I still feel like I got one." Atem winked at him and Seto couldn't help but chuckle again.

He grabbed the shower head and pointed it directly at Atem's head when he turned the hot water on. Surprised, Atem raised his arms to his face, shielding himself from the water and gasping for air while Seto just smirked.

He enjoyed Atem's struggle against the water for a while, then hung the shower head back into the holder and started to shower himself clean. He let his hands wander over his body and sighed relieved as the pain in his muscles seemed to be washed away too.

He cracked an eye open to look at Atem next to him and was somewhat surprised to see him staring with a slightly open mouth as he followed his every movement almost mesmerized. On any other occasion Seto would have just laughed at his maiden behavior but in this moment his mind and body were flooded with images of Atem writhing and moaning underneath him and the feelings of his hands and kisses on his body that he experienced just minutes ago. He swallowed hard and breathed out to calm himself when he saw Atem's mouth moving.

"Did you say something?" He asked after leaning his head out of the stream, water dripping from his chin and hair onto his chest.

It took Atem a moment to come out of his trance but then he stepped forward, wrapped his arms around Seto's hips and looked up at him with a soft but slightly mischievous smile. "I just admired you." Seto blamed the sudden heat in his face on the hot water that ran over him but couldn't help but lean his head down to touch his forehead against Atem's. "You're even more beautiful with all the marks I left all over you." His smirk was completely mischievous now but it was gone again when he started to trail little kisses from Seto's chest up to a mark he left on his neck while his hands wandered up his spine. "And for some reason… I can't stay away from you for too long."

To his surprise Seto didn't want Atem to stay away from him and to his even greater surprise he actually said it out loud. "And I don't want you to."

He felt Atem's smile against his neck and suddenly his hands weren't at his back anymore but on either side of his face, pulling Seto down to him and kissing him fully on the mouth. Seto caught his lips with his own eagerly and kissed him back just as hard and passionately, his arms wounding themselves around the small body and pressing him against him as close as he could. Slowly Atem's hands left his face and wandered back to his chest where they rested over his beating heart, thumbs gently stroking his wet skin. These soft caresses were so contradictory to their heated kissing that Seto's head starting spinning, his body became so hot that the water suddenly felt cold. He could feel his composure slipping away again but held onto it fiercely.

It wasn't that he didn't want it; in fact he wanted it too much. Whatever these feelings were that Atem ignited in him had turned into a sort of drug he was already addicted to and he couldn't help the sigh that left him when their tongues finally danced together.

All he wanted was to keep him like this, to hold him exactly like that, to kiss him until he had to gasp for air and it was in that moment that he came to his decision.

Reluctantly he broke their kiss and turned the water off since he wanted to hear Atem's voice without any disturbing background noises. He almost latched onto Atem again though when he saw his dark and glazed over eyes but he pulled himself together.

"You know…" his voice was somewhat hoarse and he cleared his throat to mask it. "You won't have to stay away when… when you spend the night here."

Atem's eyes went wide at that and for a agonizingly long moment this was his only reaction but then his face lit up and he smiled softly at Seto. "It would be the first time…" Without taking his eyes off of him, Seto nodded shortly and Atem's smile widened. "And you would let me sleep in your bed with you?"

He nodded once more, deciding against the sarcastic comment that was already on the tip of his tongue and slowly let go of Atem to step out of the shower. "That's why I asked, yes."

"I'd love to." Taking the towel Seto held out to him Atem stepped beside him and his smile turned impish. "And can we cuddle?"

Seto grunted and raised an eyebrow at him. "Don't overplay your cards or you will sleep on the floor."

Atem laughed cheery and Seto watched him closely as he began to dry himself with the towel.

Tonight would be the first night he didn't have to watch him leave. He knew it would be even harder to do so from this day forward but he was ready to take the risk.

He was ready to trust that Atem would stay.
