Papyrus sighed as he heard the the small skeleton Sans ramble about something.
"Fell! Are you even listening?" Sans snapped, as Papyrus chuckled a small laughter.
"Yeah. I was. And Papy left ME in charge of the house, so you better listen-" Swapfell Papyrus was cut off by his hand accidentally brushing against Sans' area.
Swapfell's cheeks blushed red. "I'm so sorry-" Swapfell was cut of by Sans getting a boner.
"I... I'm sorry!" Sans apologized, his face a baby blue, as in a blush.
"Don't be~." Swapfell cooed as Swapfell put his hands on Sans' shorts. "Take off your shorts Sans." Swapfell said, only too get a weird look from Sans. "T-Take of my shorts? O-Ok." Swapfell watched as the young skeleton un-done his belt buckle, then taking off his pants too reveal his hard member.
"W...What are you going too do?" Sans asked the smirking older skeleton below his waist-bone.
"You'll see~" Swapfell cooed, only for Sans too get a bit more worried. "What are you going too- Ack!"
Sans' words where cut off by Swapfell as Swapfell licked the tip of Sans' member, as Sans let out deep nasty moans. "Mm... F-Fell don't stop... Please...! It feels so good!" Sans moaned.
Swapfell then focused on what he was doing, but his eyes trained too the young skeleton every one in a while.
The young skeleton was clutching the closest thing near-by, in this case his pants, while moaning loudly.
Swapfell smirked as Sans gently pushed his hand on Swapfell's skull, making him suck deeper, as he felt Sans tense up. "F-Fell what's h-happening.....?! Somethings... Flowing....." Sans moaned, as Swapfell went faster and faster.
"F-Fell! Augh...... Mmm...... Mmm...... GAH!" Sans moaned loudly as Swapfell swallowed the blue cum dropping from Sans' member. "Don't tell Papyrus we did that, OK?" Swapfell said as he got up.
Sans nodded as he watched Swapfell go get new clothes for Sans. "Fell?" Sans said, making Swapfell turn his head too look at Sans.
"Yes my blueberry?" Swapfell teased.
"I love you, Fell."
"I love you too Sans."
