Mommy Midnight x Son Reader (Lemon)

     (y/n) felt the light streaming through the window land on his eyelids. The brightness awoke him from his slumber. Sitting up and rubbing his eyes, his vision was blurry at first, but slowly adjusted. He saw that he wasn't in his room, but that was no surprise. He looked to his side to see his naked sleeping mother. Oh, right. They spent again doing the deed. Remembering it all should bring a smile to his face, yet instead he frowned. A year ago, he would've been jumping at this, but now all he felt was apathy. He has always had a crush on his mom, the super heroine Midnight. It's easy to see why. She was beautiful, courageous, and smart. So when she made an advance on him not long after he turned 18, he was thrilled. It was going to be the dream romance he wanted to have with her.

     But he had forgotten one little thing: His mother has never had a serious relationship in her life. He was literally born from a one night stand. No one knew who his father was. There were too many possible suspects. She never got married, not even dated. She would just invite a man for the night and leave at that. Romance was never on her mind. So he should've suspected this new relationship they had was no different. She made it clear they were NOT dating. They were, as she said, family with benefits. In other words, he was just another boy toy. But he can't keep this up. That's why, later when they were having breakfast, he decided to tell her about his decision.

     "Mom, let's end this relationship we have." He said suddenly, causing her to choke a bit on the toast she was eating. "What? Why? It better not be because you think I'm getting old!" He raised his hands up. His mother could be scary. "No, I just want a more serious relationship with someone. And I know you won't progress ours beyond sex." She raised an eyebrow. "Beyond sex. Isn't sex the deepest you can achieve in a relationship? I think I'm offering you a good deal. You get sex whenever you want, you don't need to leave the house or invite anybody over, and you don't have to deal with the nonsense that dating requires you to do like dates or keeping up appearances. We just get straight to why people date in the first place. To get laid." He sighed. This mentality was precisely why their relationship would never last.

     "That's what you're not getting. I want the full experience. For me, I don't want just sex. I want something actually meaningful." He tried explaining. She huffed. "Well, you're right. I don't get it. What would you gain from such a relationship?" He sighed dejectedly. "I would tell you, but I feel like it would make no difference." Midnight was frustrated. Her son was being naive, but she decided to give in. "Okay, but trust me, getting a girlfriend won't be easy. I could give you a few pointers on how to get" "That's okay. I already have one." He interrupted her. Her widened. "Already?" He nodded. "Momo asked me out the other day. I said yes. It just took me till today to get the nerve to tell you." Midnight didn't know why, but hearing that made her upset. She put on a fake smile. "Well isn't that wonderful, how about you invite her over to dinner?" He agreed, relieved she seemed to have readily accepted it.

     And so the next night, Momo came to visit. "Hello, Ms. Midnight. It's been awhile. I hadn't seen you since I graduated from U.A." She greeted her former teacher. "Same. It seems you have developed quite the reputation as a hero." Though their words and expressions seemed polite, there was an underlying tension between the two. The three made little chitchat until (y/n) excused himself to go to the bathroom. With him gone, they were free to drop the niceties. "So, he chose you? Sure, you have a nice body, especially those melons on your chest, but can you handle as he prefers. He's always been a mama's boy, and needs a woman who can tell him what to do. But I remember you being so innocent though." Midnight remarked. Momo replied. "I'll do what I must to please him. At least I know how to outside of bed."

     Midnight  froze before showing a serious expression. "So, he told you about us?" Momo nodded. "I'm aware of your FORMER relationship. Part of dating someone is not keeping secrets. So, I'm gonna make this clear. He's mine now. I'm not going to allow you or any other girl to touch him." Midnight smirked. "Well I've already touched him plenty. I did things to that boy that your inexperienced mind can't imagine. How do you expect to beat in that?" Momo sighed. "He was right." Midnight looked confused. "About what?" Momo answered. "That you only think about sex. No wonder he dumped you." Midnight glared. "One, we were never dating. We were just family with benefits." Momo grinned triumphantly. "And that's why he won't be in your bed from now on." Before midnight could rebuke that comment, her son returned. The night went on as before. After word, (y/n) drove Momo home.
