Asriel was fifteen while Frisk was fourteen and the two of them just got hit with puberty like a home run. Frisk's symptoms usual the only exception is when he got acne everyone almost fainted. Asriel on the other hand was all sorts of outta whack. He kept getting hard for no reason he also he had a hard time keeping control of his member and Frisk was no help.
He then sat on his bed next to Frisk the only thing dividing them is a lamp. "Good night Frisk" said Asriel. "Good Night" said Frisk back. As the duo started to drift off they heard a door opening. The two raced out pushing each other then saw sans with a pack of chips. "hey, bros just stopping by" "Hey sans is Papyrus coming to?". Sans shook his head and said he just needed to fix Toriel's fridge. Sans once he came to the human world he needed a job so he became a couple and this is only a temporary job. "You two go back to bed before Toriel becomes angry" said sans sorta whispering.
The two quickly ran upstairs to tuck themselves in. After a while of waiting to see if sans and Toriel would go in the garage. They had there nightly conversation. They usually talked about school and what happened at it but that's not all they also talked about sex well that was usually the end of the conversation but tonight was different. They heard about Tommy and Sarah well no details required.
The problem was with this was Asriel felt something while they were talking. He knew. He had to do it now if not he was going to have a bad time. "So I'm going to limit the details for known reasons so he the-" "Frisk I need to go to bed I don't feel to good" said Asriel. "O-ok we'll talk about this later" "Sorry" said Asriel. After a while Frisk fell asleep it was time for Asriel's plan. Asriel quickly pulled down his pants and it revealed the bulging part that's about to spill it's liquid. As he reached down he feared Frisk was still awake. Although in that worry he did it anyway he put his hand in his pants and started slowly then stopped. He then grabbed a pillow and rubbed it against the soft cushion. Asriel faintly moaned again, again and more. He started to clench the bed sheets going faster and faster with faint moans saying "Frisk, Frisk, Frisk" progressively getting louder and louder. "I want he.. to have .. Heh you" moaning like he was outside. Now he was drooling still humping the pillow. "More, more, more!" Dreaming of Frisk humping him inside of a store no, their room, no anywhere Frisk screaming "Yes! More more more Asriel more! Please fill me with you" YES I WILL FRISK YES I WILL MORE MOREMORE PLEASE BABY YES I DON'T CARE IF THIS IS GAY HAH HAH HE….. As the more he thought of him he went faster and faster. "Hoo HAH heh heh YES!" loudly moaned Asriel. He just hit his climax and he knew what was next. The liquids were spewing everywhere all over the pillow the bed sheets which he had been biting the entire time. Asriel stopped and saw what was all over the bed and pillow he was sweating and covered in saliva he quickly hid the pillow an the sheets and went to bed hoping Frisk wasn't going to find out and dreaming about Frisk's sexy nightmare.
