(So the background is that blue prevents his friends from hurting his best friends by saying he would be their servant we shall start there.)
No one's POV:
Blue, Ink, and Dream were all badly beaten and weaken to the point of death. Nightmare getting ready to rid of his twin for once and for all. "Wait! Take me instead! I'll heal up your group if you leave my friends alone!" Blue spoke out of turn but his friends were worried for their friend. "Don't do this blue!" Ink said trying to keep blue from doing something he'll regret. "I'm sorry Ink, Dream but to protect you I'm willing to sacrifice myself so you guys can find me one day no longer doing this in the future promise me you'll save me one day." He said walking over to Nightmare. "Very well blue but don't fall for any tricks my brother may though at you!" Dream shouts at them as they enter a portal. Blue waves goodbye for the very last time he will see them.Nightmare had blue fix each person that was badly damaged from the battle. Blue starts to heal them slowly and steadily knowing not to strain his own magic power. Slowly he got up to the king and starts to heal him the best he could before fainting from to much magic. "I'll take him to his temp area room the rest of you guys do your own thing!" He told his group as they left Nightmare alone with blue. Blue was soon taken to a room to rest to heal his own injuries as well.
Nightmare knows that blue will try and keep them from hurting his friends but chose to keep him as a servant that will heal and get a bit better in battle after staying here for a couple of months or so. "Don't worry blue I won't touch your friends in exchange you learn something that your friends never taught you. To be more strong instead of weak and cry every five seconds or so." He said to the sleeping blue.
Time skip to after a bit of training and learning of the castle blue knows mostly everything he needs to know.
Nightmare's POV:
I smirked at blue trying to keep us from hurting people even though I took a week off from evil he wants us to try something new I ignore him and do my own thing. "Alright blue that's enough no more begging for non violent we need to get our energy out some times or else I'll kill everyone you love!" He said to blue laughing evilly. Blue stops and starts to tear up a little. Since he has been here he still gets into a crying fit once a week instead every minute like the first two weeks here. "I'm sorry I should head back." He said walking away crying softly.I start up an idea to calm him down knowing the others want my to apologize for what I did wrong. I walk out to find blue hugging a teddy bear I let him have. "Look blue I know you want to be helpful and all but can you please stop crying?" He asked blue calmly. Blue starts to clean his face. "Well I'm sorry for being to into the non killing." Blue said back to nightmare with a small smile.
"Hey blue want to know how you can help~?" Nightmare asked softly almost into a purr. "What is that?" Blue asked. "You can help me with my heat~ usually I just do it myself but since I have to make you smile then I will~" Nightmare said softly trying to make blue feel hot and needy.
No one's POV:
Nightmare has blue starting to feel the heat and also wanting help. "Shh don't worry just focus on my voice nothing but my voice~" He said in calming voice almost as if blue needed that voice to focus. Blue starts to undress himself in front of Nightmare with a teasing smile doing it slowly. Nightmare smirks at this liking it even growling softly. Nightmare took off his clothes as well once blue got on his lap. "May I please give you a lap dance my king~?" Blue asked him which Nightmare nodded to him. Blue starts to hump him slowly trying to feel it out the best he can.Nightmare watches as blue does the lap dance with ease. "Would you like a tendril to suck while I fuck you on the wall~?" Nightmare asked blue. Blue of course nodded to the option little does he know Nightmare will make sure blue only feels pleasure and want him. Nightmare gives him a tendril as his picks him up and heads to a wall to fuck him up. "Don't worry only suck the tendril as your body feels so good~" He said to blue once Nightmare puts his dick into him. Blue started to suck the tendril almost begging for more fun. Blue's body was a female body easy for nightmare to destroy with his big dick. While Nightmare was having his fun going at a fast pace as blue sucks more not knowing he will be one of Nightmare's pet that day. But as Nightmare move as fast as he possibly can move not giving blue's body any time for adjusting from the start his body felt a bit raged out from the tough waves of pleasure he feels. He decided to slowly down and pull his tendril out of blue's mouth to hear him beg for him. "Oh blue beg your master for more and to not leave my side~" He said softly.
Blue nodded he took a breath in and then out before he starts his begging. "Please Master go faster and harder make me one of your pets~~!!" He screams yo nightmare. Nightmare smirks hearing this. "Good boy~" Nightmare purred giving blue what he asked of him. Make sure blue cums first before him. "Cum for your master~ cum like you need my seed in you body~" He purred to blue which of course made blue release himself on Nightmare's dick and soon gets his seed into him. "Good pet~ such a obedient servant to your king~ I'll make sure our kids know how to fuck anyone they want~ but not you Your my favorite pet you'll never ever leave me will you~?" Nightmare asked blue as they lay on the bed. "Yes Master I will not leave you or our children~ I'll help them learn to take anything they want and let them want to fuck me but can't~" Blue purred back snuggling into nightmare's chest feeling safe. "That's good my pet~"
As for saving blue dream could only find out the horror of what they did while blue said it felt as if he was in heaven and doesn't want to leave nightmare because he made a promise of some type. Dream told blue just try and leave when he could.
(I hope I gave this person what they so much as Desire from me~)
