(This is kinda like the same au but I saw before that they have like part for their dicks/pussies so this is gonna have that kinda)

There had been a storm and both geno and blue were trapped in their homes. Blue had purposely left his part at genos house for him to play with if he ever got horny.

The two agreed to go on Skype and talk. Blue watched his laptop screen intently as he called.

After a few rings genos face appeared on screen and blue smiled

"hi babe!"

"Hey baby blue"

Geno had a blush on his face and it was very visible.

"What's up? Why are you blushing?" He asks and geno sets a hand over his cheek in attempt to conceal his blush.

"Eh lust sent me some porn again and I ended up watching it" he said and blue giggled

"That's not really surprising. If you want, you can use my part~" blue flirted and geno couldn't help but blush more.

"Only if we stay on call, I wanna hear your cute moans" geno stated and blue agreed to it

He went to go grab it and soon he reappeared in front of the laptop screen again with blues part and some lube.

(This kinda weird ngl)

Blue watched as geno poured some lube onto the part and blue could feel himself shudder. He would never get used to that.

Soon geno slid his dick into the part and blue let out a hum. It had been a while since they last had sex so blue had healed back to being tight.

Geno got his tip in and blue grasped his bed sheets "f-fuck" he whimpered and slammed his eyes shut

"You okay?" Geno asked and blue nodded "keep going" he was able to say and with that geno continued. He continued to push until his member was finally all the way in.

Blue had tears streaming down his face at the pain but he knew it would go away soon. And it did. The pain mixed with the pleasure as geno started to thrust.

Blue felt every bit of it and was a moaning mess. Each moan that was heard from genos laptop drove him to go faster. Blue tried to quiet himself down but that was impossible. He just hoped that his brother couldn't hear him.

"A-ah geno! Dont stop!" He moaned and geno did as he was told and got close to his climax.

Blue whimpered and tugged hard on his sheets and he soon arched his back and released his cum onto genos member. Tightening his walls as he did so, making genos dick release his seed, deep into blue's part. Blue let out a large moan and went limp and so did geno.

"That was so fucking good" geno cursed and blue agreed.

The two cleaned each other up and ended the call. Papyrus gave blue a major talking to about his volume and what exactly he was doing. And the smaller skeleton agreed to not do it again when his brother was home.

(Done!!)
