They both stilled at the same time as they heard boots
kicking the ground in front of the door, most likely to get the snow off of
them. Stretch and Razz looked at each other, both of their faces flushed as the
smaller skeleton was still pinned to the wall, his legs wrapped around the
other’s hips as their manifested magic glowed under their clothes where they
were grinding against each other just moments ago.

At the sound of a key connecting to the lock, Stretch did
the only thing he could think of in his panicked state: he teleported. Funny
thing is, if you don’t have your shit together in your head, who knows where
you end up and, unfortunately, they didn’t get too far, landing on the kitchen
floor, Razz, on top of Stretch who quietly groaned.

Razz looked around and noticed that they were at the
furthest corner from the entrance of the kitchen and no one would be able to
see them until they stepped in the room. He turned back to the taller skeleton
who still hadn’t realised where they landed, but before either of them could
whisper, they heard the sound of an opening door and shuffling, as Blue stepped
inside and closed the door. When his younger called out his name, Stretch wanted
nothing more than to run away and hide, but when he tried to move, his hands
were pinned to the ground and a hand clamped on his mouth, preventing him from
giving out any noise from it.

When he looked up, his gaze was met with Razz’, who had a
smirk on his still flushed face and used his legs to pin his arms down as he
also squeezed them to his own body. He was confused, until the other skeleton
grinded against him and he was painfully reminded how close both of them were
to come before his brother interrupted them. He tried to hold back a moan as he
squirmed under Razz, trying to get out of his hold but it was useless, the
other skeleton had a hold of him.

“Papy, are you home?” he heard Blue’s voice getting quieter,
most, likely going up the stairs, but he couldn’t focus as the alternate
version of his brother was rutting against him, every move harder and faster
than the last one. Razz was panting and Stretch was now glad the other’s hand
muffled the sounds coming from his mouth because no matter how he tried, he couldn’t
hold back the moans of pleasure as he started to move his hips to get more friction.

He felt how close he was to the edge of climaxing, his cock
twitching at the now hard and frantic grinding and Razz must have noticed too,
because he leant down, his tongue licking the other’s neck as he whispered only
one word:

“Come.”

Razz bit down on his clavicle, and that was what made
Stretch go over the edge, his cum spurting on his already soaking pants as he
bit back a cry, shaking a bit. As Razz rode him through his orgasm, he came too
with a quiet groan, Stretch feeling as some of his come dripped onto his femurs
as he tried to catch his breath.

They didn’t hear the kitchen door opening, but they
definitely heard the loud gasp, shortly followed by a shout that had them both
flushed with embarrassment and surprise.

“RED OWES ME 20G!”

Oh my god—I didn’t need more motivation to write for this pairing, damn it!

But wow, this was wonderful. Razz, you asshole. You did very well with the smut! I really enjoyed this.
