A/n: Now before we begin let's have a little foreword. I discovered this series way back, maybe about three years ago when it was released on Netflix, so I don't know as much as a more avid fan of the series would. When I can get my hands on the manga, or a site that has it I'll definitely read more, but until then you're stuck with my lewd, yet surprisingly vivid imagination based on what I've seen from the anime. That being said I didn't come up with this idea on my own, I got the idea from another author on here, LauraRose876
So be sure to check her out as well! She's an awesome author Who's writing her own one-shots, based on the requests of her fans, I may have requested something from her myself so definitely keep an eye one there

The wind howled on the battlefield as Meliodas of the seven deadly sins faced off against his brother Zeldris of the ten commandments. The two were locked in lethal combat trading blows left right and centre as their comrades looked on in both awe and fear.

"Just you wait Meliodas. I won't forgive you for what you did 3000 years ago. You will die by my hands even if it means I have to kill all of your friends." The black haired boy said coldly, his eyes like daggers that pierced the soul.

"Well I have some people that I made a few promises to, so you'll just have to wait in line." the other boy said nonchalantly. "Besides, are you sure this is what Gelda would want?"

"Don't you dare speak her name, you don't deserve to even know it." Zeldris rushed at Meliodas at full speed, ready to deliver a lethal blow. off in the distance, a silver-haired woman ran towards the fight with tears in her eyes.

"Sir Meliodas, look out!" She exclaimed in panic.

"Don't worry Elizabeth, I'll be just fine!" He said turning to face her. His voice was calm and reassuring, but his body locked up instantly.

"Turning your back on your opponent when you're in the middle of combat? That's as good as betrayal, and it can't be helped that my commandment shuns such ideas. You belong to me now, by order of my commandment. Piety." Zeldris stopped running and started walking deliberately to his elder brother. "This is the woman you betrayed us for?" He said looking towards Elizabeth. "Pathetic. But I suppose it can't be helped, I lost my love now you too can lose yours."

"Don't you dare hurt Elizabeth!" Meliodas said with spite in his voice.

"Oh don't worry I won't hurt her. I'll just show her how truly useless her lover is. Now Meliodas, rise and come to my side." Without control of his actions, Meliodas followed the orders given to him to a T. Zeldris turned to face his brother and kissed him deeply, Meliodas was taken aback by this but couldn't do anything to stop it. Zeldris released the kiss. "Now strip for me, make yourself look as pathetic as I know you are." Meliodas was forced to obey, and slowly started removing the clothing that Elizabeth had made for him, all of his actions were slow and deliberate, like a dancer on stage.

"S-Sir Meliodas! What are you doing?" Elizabeth said blushing a deep scarlet as the man she loved started stipping for his younger brother. "You can fight it Sir Meliodas! I know you can!" She said with encouragement in her voice.

"Dumb girl. No one can resist the curse of our commandments, not even us. So really telling him to resist it is like telling a fish to walk on land, it's just not gonna happen." Zeldris said with a cocky grin. "Now brother I want you to undress me, be the good little slut we all know you can be."

Slowly Meliodas started to shed his brother of his clothing, making sure to grope, stroke and feel every bit of his exposed flesh as he revealed it, taking his time to revel in the feeling of skin on skin contact. The blonde traced kisses along his brothers smooth skin before finally all of his clothing was removed. Both men were now naked staring at one another.

"Now brother, I want you to suck my dick, get me nice and hard before I take that tight ass of yours." Meliodas obeyed and got on his knees before taking Zeldris' hot member into his mouth. He started bobbing his head up and down in slow deliberate movements all working towards to same goal. Meliodas removed himself with a resounding pop exposing Zeldris' now hard cock. "Now turn around." Meliodas positioned himself so that he was exposing himself to his younger brother.

"Sir Meliodas you can't really mean to tell me that you're going through with this. It just isn't like you." Elizabeth said through teary eyes. Zeldris grabbed Meliodas' back and position himself at the entrance to his hole. Without warning he rammed his cock all the way in without given his brother the chance to warmup. Zeldris continued his assault on his brothers ass for a good 10 minutes, Elizabeth shamefully enjoying herself, before he finally came inside. He threw Meliodas to the ground.

"Now brother. When I leave you'll return to your little princess and forge anything ever happened. You will act of your own free will until I give you another order. Remember. You belong to me now." With that Zeldris took his leave of the place. Meliodas returned to Elizabeth with the same goofy smile he always wore.

"So Elizabeth?" He asked casually groping the young woman. "You smell nice, what happened?" The silver haired girl just blushed and smiled to herself.

"Oh nothing. You just took a nap and I took advantage of the privacy." She said courtly. And Meliodas was none the wiser.

A/n: Oof. This has been sitting here for quite a while. But it's finally done. If the smut seems rushed, it's because it was. I'm not used to writing smut, let alone writing a lemon. This was a first for me and I will definitely keep trying to improve. Until then, I'm outie. Peace!
