Sans looked at the video in utter embarrassment. The video mettaton gave papyrus was...erotic. I mean sure, he and papyrus have done sinful and kinky shit that was far more from brotherly that should only be seen by the devil's eye, but still!

This video, showed CHILDREN. But not just any children, no it was them as KIDS. FUCKING. Oh god this wasn't allowed of course incest was okay with monster kind, as long as it had to do with their increase in species. But this is children. This as greatly frowned upon, child porn was a forbidden act that if you ever told a soul, you would've been reported. Oh god this was the end for him, for papyrus too. And his future child!

"Pap? Does anybody else know about this?"

"Well, mettaton and Alphys know cuz they gave it to me...but no." Sans' head faceplanted with the table as he feels that his life is ruined.

"Brother! Don't do that you could hurt yourself!"

Sans knows that Alphys wouldn't rat them out. Afterall she was the one who found it. But it wouldn't stop the skeleton from feeling embarrassed. He groans as there was more secrets to uncover about himself that he didn't even know of. Not only was he unknowingly pregnant through out most of his life, he committed the most forbidden act to all monster kind. But of course that time when papyrus and sans agreed about that night that never happened, was forbidden too as they weren't that old either. They were at least ten at that time. Of course he would have admitted it felt nice to be pummeled into that mattress. That night was something that made him craving for more. Their heavy breaths and moans fill that room. Pleasure being the only thing wanting from his brother. Sometimes he would feel the pulsing of their magic against each other, cause excitement up from his skull, down to his toes.

A jolt of pleasure shot down his spine. Oh shit. Sans was getting aroused just by thinking of that night. They already resolved that as they were already a couple! Oh god, sans' wet heat began to soak his shorts. Of course papyrus didn't noticed because he was hiding it underneath the table. But of course, his magic began to give it's sent to it's mate that would freely fuck it properly. Trying to make itself know to the other.

"Sans? Brother, it not that bad-!" His words suddenly stopped as it struck him. Awkward silence passed through the both of them. Papyrus waited for sans to say something until sans' arousal was taking a toll on him to realize what was going on.

"You're wet aren't you?"

"I was trying to hide it..."

"But not that well huh?" Papyus smirks so smug.

"Shut up," sans chuckles as he blushes even more. "Can we 'knot' do this right now? I'm already starting to 'cum' up with puns already." Papyrus groaned as he felt like the mood was crushed(it was).

"Uuuuuggghhh...stop!" Sans laughed some more. He stood up from his chair, as he started to drag papyrus to the couch.

"Let make a mess all over the couch. Sides, my child needs it's daddy's magic doesn't it?~" papyrus flushes at this as sans began to pull his blue speedos down to come face to face with the erect member. It was then sans looked at it with pure hunger. He slowly licked the shaft as papyrus began to suck in a breath. Pleasure once again to go to his twitching cunt. More of his sweet fluids began to soak even more of his shorts, soon coaxing all over his pussy and his inner thighs. His plush ectoflesh like the colors of sapphires.

"Sans, you're going to make me come so soon." Papyrus' hands began to hold sans's skull. Papyrus then started to snap his hips forward toward the warm moist cavern of sans' mouth. Sans choked at first. Not used to the sudden movement, but soon got used to the sensation as the tip of papyrus' boot began to rub his cunt. Sans then started to pull of his shorts as his fluids were making it cold for his formed ectoflesh. As soon as his shorts were off, with struggling effort, papyrus' boot went back to work. His boot pressing perfectly on his love button.

Sans moaned on the dick at the movement. Sans hummed in satisfaction as the boot sent pleasure through his body. They began to rut against each other, as they tried to get off. Papyrus' grip on Sans' skull tightened.

"Sans! Hah...I'm gonna-!" A large load of papyrus's seed shot in sans' mouth. Sans tried to swallow it all, even though some shot in his mouth too soon to make him cough it back up again, but he needed to. He wanted his child to grow strong. So the only way to do that, is drink every inch his brother's semen. And it felt good too. To feel that hot sperm in his whom. Surrounding the small souling that was his. He could even feel Papyrus' sperm heat in his whom that it made him wet even more. Sans rutted up against papyrus' boot even more as he didn't cum yet.

"Pap...Papy...I need..." papyrus shushed him. He picked sans up, letting him sit near his already re-erected cock, due to sans' whining. Sans began to grind again the member, making papyrus gasp at the delicious friction. He began to thrust up against the wet heat. It was like we're in a sensual never ending dance as they grind against each other. Sans wrapped his legs aroung papyrus's pelvis as trying to add more pressure. Papyrus tried to push sans' heat away to push in, but sans wouldn't stop. Sans was gasping as every inch of his bones were vibrating. His voice laced with pure lust.

"Pap! Papy! I'm gonna cum!!"

"Sans wait-!" Sans' hot liquid squirted out coaxing papyrus' shaft. Papyrus sucks in a breath as the sudden substance came in contact with his dick. Meanwhile sans's grip around his pelvis began to loosen at his release. Sans was breathing heavily as he tried to get down from his high.

"Pap...so hot...so good. Hah...I want you...inside." Sans then started to guide papyrus' cock towards his cunt. He began to position himself as he was aligning papyrus where he can immediately hit the right spot. Papyrus watches as sans was trying to get into the right position. It wasn't until sans began to sink down. It was so slow but so fast as sans's tight wetness enveloped in cock. It was so warm. Papyrus twitched which caused sans wither in pleasure. Sans then started to begin a slow steady pace. The squelched sound of them joined together with their gasps and moans that filled the room. Sans started to speed up. Their breathing becoming more ragged. Papyrus then grabs a hold of his hips and slams him down on the large member. Sans then gave out a yelp. Papyrus kept that movement. Going up and down, up and down, but forcefully.

"Paps...that so good! Faster! Harder! Please! I'm so close!" Their movements began to grow more frantic as sans was practically bouncing on his cock. Their dance of passion was exhilarating as they were close to their peak.

"S-sans! I'm-!"

"Yes! Cum inside! Please!" Papyrus' sum shot through sans' channel to his whom. Sans clamped down as his fluids once more shot out. Sans grinded down as papyrus was already hilted to his limits, but he wanted to keep his cum inside. The little souling began to glow as it fed off it's parent's magic. Sans and papyrus watched as they both tried to relax. Papyrus put his bones hand on sans' stomach.

"It's beautiful. Our child's beautiful. You're beautiful."

Sans chuckles at this as his breathing became more steady.

"You're only saying that."

"No, I mean it brother," papyrus kissed the side of his skull. "You're gorgeous." The huddled close as they decided to nap on the couch. Usually what sans would do, but, it would be acceptable for now. As sans knocked out, papyrus wouldn't stop staring at his whom.

How did this souling came to be? Why now?

"I'm sorry bro," sans' tears fell as papyrus looked at him with shock. "I told you it was a bad idea."

Papyrus brought him close as he looked as the now empty whom that held sans's child. Their child. It's gone. Nothing can bring back the life they created. And for once, papyrus felt a horrible hatred towards Gaster for stealing that away from him. He wanted it. He wanted it so bad. To see his brother full of his children. He didn't care if he was too young, he loved his brother, and if having a child with him show he loved him very much? Then so be it.

Papyrus glared at Gaster as he was doing his regular tests. They sat there in silence.

"Aren't you going to tell me something? ...2-P?"

Papyrus just scowled at him as it angered him more. He just took away what was his and feels nothing for it?

"Why? Why did you do it?"

"Isn't obvious? Things can't have children. You're just a test subject. You weren't allowed to fall in love with 1-S actually. You and 1-S are just guinea pigs. Nothing more. In fact, I didn't even KILL the child. I just put it in dormancy until 14 years, but it obviously can't grow up without one single parent's magic, but it doesn't mean any monster can can take the child out of dormancy, the original father has to give the child it's magic. Or else that child isn't going to leave 1-S without it's need to develop. But once 14 years pass I will have to take that child out of dormancy and kill it."

Papyrus couldn't believe his words. At first he was relieved that his child was still alive. But once 14 years pass, sans was in trouble. It was obvious to papyrus now. For once in his life he knew exactly what to do.

He and sans had to get out of here.

(Bam! It is done!!! Some little smut for you until the big nuke happens on tumblr...enjoy while you still can...)
