Hey guys! I was actually planning to update weekly, but I got too happy. Thanks for all the kind reviews! They really motivate me to continue updating as soon as I can! So let's get on with it...

Warning for this chapter: Smut between father/son

He knew he had to stop. He really wanted to. If he continued, then it will hurt both of them. His son will get hurt, he will get hurt, and their relationship with be ruined. He knew what he had to do. His insides were beating him up, yelling at him to stop. His mind understood, his heart understood, every part of him understood.

Except for his body.

He started to kiss Kurt's neck, causing the boy under him to moan softly. "Stop, you idiot! This is your son! What if you hurt him?" His mind kept yelling. Then again, Kurt was the one who initiated the kiss. The kiss that turned into this. His son didn't respond when he said he wanted to make love to him, so he was unsure whether Kurt was okay with this or not. Should he ask him once more? Sebastian looked at the boy's face.

Holy fuck.

Kurt was had his eyes slightly open, but Sebastian could still see his eyes. It was full of lust, yet mixed with innocence and purity. Red started on his cheeks, then the beautiful color faded around all over, down to his neck. His mouth was parted a bit, and it opened wider when he released a moan.

It was the most beautiful sight he has ever seen. It made him feel aroused. It made him feel satisfied. But it also made him feel disgusted. Because this sight contains his son. His son. Sebastian kissed somewhere around his collarbone before lifting his upper body with his arms straight, just to admire Kurt.

"Daddy..." Kurt managed to say in the smoothest, sweetest voice. The older man kissed his forehead and stroked his cheek gently. "This is wrong...isn't it?"

Wrong? Of course it is. To be perfectly honest, he thought Kurt had no idea this was wrong. But he did know. "I'm not going to lie. This is very wrong." The boy under him sighed softly. "Tell me to stop." Then he looked back to his dad. "If you don't want this to go on, tell me to stop. Because if you don't, I will go on, and you might regret it."

But Kurt shook his head. "What if I want you to go on?" This time Sebastian sighed. "Or do you want to stop this? Is that why you're telling me to say that?"

"No. Not one bit. It's because I want to do this. I want to do this so bad, but I'm worried about you. I don't want to be the reason that you're going to regret one thing for the rest of your life. So I want you to really think. If I go on, then this might not be able to continue for the future, or you will live with a huge regret. But if you tell me to stop, I will, and we can just forget about this."

Kurt looked as thought he was thinking. "I want to do this. If I regret it, then I can blame it all on myself." Sebastian was about to say something, but he was stopped by the determined look that appeared on his face.

"Kurt...before this I said that I wanted to make love to you. Will you...allow me?" He nodded as he bit his lip, and fuck, if that wasn't one of the hottest things that Sebastian has ever seen.

So he proceeded. He bent his arms so he could kiss Kurt's lips, then he start to move down his jawline, and started sucking on his earlobe. The younger boy gasped at the sensation. After a few kisses, Sebastian wanted to see Kurt again, just so he can make sure he didn't mind if he went lower than his collarbone. He straightened his arms again, and stared at Kurt completely. He was just about to kiss his chest, when his son reached out both of his hands to hold Sebastian's shoulders. He knew this gesture. He knew this gesture very well.

He slid both of his hands under Kurt's back, then he leaned down to hug the boy. They both held each other, and after a while, Kurt said, "I love you, daddy." Crap, Sebastian was close to crying. He held the small body a bit stronger, and dug his face into his shoulder.

"I love you too, Kurt."

They just stayed in that position for a moment, before Sebastian moved his hands to the place it was in at first. Kurt watched as his dad kissed, then started to suck on his neck. He released a moan, which encouraged Sebastian to go further. A few seconds later, he pulled away and saw the mark that he left.

Once he has done that, he kissed down to Kurt's chest, then sucked on his nipple. His moans became more passionate, louder, and the more he worshiped his upper body, the more he moaned.

Sebastian fondled his other nipple, and soon he was sucking on it. The boy underneath was crying out, begging for more. It didn't take long for nipples to get hardened, and with that, Sebastian continued.

Kurt still didn't have the shirt completely off, but it was fully unbuttoned. The man slowly slid down his briefs, but the boy stopped him. "Can you...take you shirt off?" Oh right. He was still clothed. So he took his t-shirt off, and although Kurt didn't ask him to, the pants came off as well. Once done, he slid down the boy's briefs, revealing his perfect cock.

It may sound weird and creepy for someone to describe it and admire it so much, but Sebastian can't help it. It was just the perfect size for Kurt's slender frame, and it was slightly pink because of the arousal. It was leaking with pre-cum, and he couldn't wait to lick it. Feeling as though he was waiting for nothing, he began by kissing the tip, earning a sharp gasp from the one receiving. As the kissing ended, it turned into licking, and finally sucking. Sebastian started slow, but deep. Kurt was whining helplessly, with no idea what's going to happen next. As he fastened his pace, the closer the boy was to reaching his first orgasm. A few moments later, he came in his mouth, with a few drops of the sticky white substance dripping out. But without hesitation, he licked all of it.

Kurt's breathe was quick and short, so he was given time to relax again. After a minute, his breathing was slowed down, so Sebastian proceeded. But just before he was about to, he was stopped. "Can I do what you did?"

"You don't have to."

"But I want to." Sebastian wanted this to be about Kurt, but he realized to make it truly special he needed to make it about both of them. So he helplessly nodded as he slid off his own briefs, and allowed himself to sit back while the small body moved to crawl over to him. In that position, he moved his face closer to the man's cock, but he had a few seconds of hesitation. "Will you get mad if I do something wrong?"

"Of course not. I don't believe you will. Besides-oh!" He was cut off with Kurt's wet mouth sucking the head of his cock. This already felt so perfect, imagine how it would feel if he sucked deeper. It was so perfect, yet so imperfect, but that fact is what makes it feel the way it is. He started to suck deeper, and tried to take all of it, and surprisingly, he didn't gag. Before he was about to reach his orgasm, he stopped Kurt.

"Why? Did I do something wrong?" His son looked up at him.

"No, it's just that I want to come later." Kurt nodded his head, and took note of what he meant by coming. "Lie back down." He said softly. So the boy did as he said. He slowly leaned back down against the pillows and the shirt started to fall off his shoulder a bit. Sebastian thought that maybe he should take it off, but then he realized the thought of Kurt wearing his shirt as they make love is so memorable (and sexy). He reached over to the nightstand and pulled out the lube and condom out of the drawer.

Sitting on his knees, he lifted both of Kurt's slender legs and place his ankles against his shoulders, just so it's easier to open him up. He picked up the bottle of lube and poured a decent amount on his fingers. Like before, he checked Kurt's expression before doing so. With that expression on his face, he was sure it meant that he had the boy's complete trust.

Kurt had absolutely no idea what he was going to do with his fingers, but he was about to find out. Sebastian slowly pushed one finger inside, and the teen had his eyes shut at the sensation, with a irresistible noise coming out of him. "Does it hurt?"

"Only a little bit-ngh!"

Sebastian started to search, and once he hit the spot, Kurt cried out of pleasure. He started to rub against it, and his moans got louder and louder.

"Daddy! Oh-" Broken words were escaping through the boy's delicate lips. He started to yell what he calls his father, but Sebastian wanted him to call out something else.

"Kurt..." He said as he added another finger in, earning a groan. "Don't call me daddy for tonight, or for anytime we do this." Kurt tried to open his eyes to look at his dad, but he couldn't. "Call me by my name."

As he started to stretch out his hole, the high and angelic voice tried to speak, "B-but dad..ngh! Isn't th-that impol-lite?" He shook his head.

"It is if you're saying it out of anger." He explained as he added a third finger. "If you're saying it out of love, then it's makes me happy." He smiled at the boy beneath him.

Once he was fully stretched, Sebastian ripped the packet open and took the condom out. Kurt was curious on what it was, and again, he found out right after.

The man rolled the condom down his cock and added a generous amount of lube on it, then he kissed his son, before saying, "It's going to hurt at first."

"But how will it fill after that?"

"It will feel amazing, Kurt. But tell me anytime you feel too much pain." Kurt nodded.

"Okay."

Sebastian stroked his cheek before pushing himself in as gently as he can. No matter how gentle he was, Kurt still felt pain. He cried out and tried to hold the tears from running down. "Do you want me to stop?"

"No, Sebastian..keep going. I'll- I'll try to handle it." Sebastian noticed that Kurt didn't forget to call him by his name. Once he pushed himself all the way in, he needed to make sure the boy was used to it.

"Can I...go on?" Kurt nodded. So he slowly pulled himself out, then back in. It took a few moments, but soon, the pain was gone for Kurt. He started to go faster just a tiny bit, receiving sharp gasps from the young one every time he pushes himself in.

It took all of his willpower not to fuck his son fast and hard that it looked like he was raping him. But all he needed was patience, because now, Kurt was enjoying it.

"Sebast-OH! Can y-you go f-faster?" The boy was begging now. It made him happy, that he wasn't hurting him anymore. And so he did what he was told to do. He grabbed Kurt's thighs, and started fucking him deeper and faster, but not too fast that it will hurt him again.

The noises became louder and louder, and Sebastian could feel himself coming close to his orgasm, and before that moment, he stroked Kurt's cock. A few seconds later, they both came.

Obviously Kurt was tired, because he came twice. Sebastian took his condom off and threw it somewhere around the room. He released the boy's legs, and allowed him to relax. Once he caught his breath, the older man leaned down and hugged his son like he did before. He rested his chin on Kurt's half-exposed shoulder, and asked, "Is it ok if I sleep like this?"

"Of course." Kurt answered, as he moved his delicate hands to hold his dad's back. "I love you."

"I love you, too."

Was it nosebleed-worthy? No? Okay.

Sorry that the chapters are really short. I'll try to make them longer next time. Usually I'm either cut by something I have to attend to, or sometimes I fall asleep. Just kidding! I really meant the first one, but of course I won't fall asleep writing something like this! Something...not that good.

Once again, thanks for the reviews! Please continue reviewing and giving me some suggestions! Bye!
