shy/jealous siren sans x pirate badass reader part 2

It had been about 4 years since you and sans got married and had kids (key letter: S) a boy and a girl called (I'm choosing the names deal with it) Coral (the girl) and Ocean (the boy). Sans is the why type so just to tease him you flirt with him and tease him with pleasure like using a pick up line or pinning him to the bed/couch/wall/furniture/rock but ever since you met papyrus sans has been 'secretly' acting jealous which you soon enough caught on about 5 months after the honey moon (you met papyrus after 2 weeks of being together with sans)

Flashback

"Heya guys great to see you again" you said
"HELLO (Y/N)" Papyrus said while shaking your hand making sans jealous. Sans kissed you but it didn't last long because coral hugged you " MOMMY/DADDY! " she shouted (coral is a siren like sans while Ocean is your species  but if you are a species that lives underwater then say that you are captain of a pirate crew and Ocean saw how awesome it was and wanted to join so you, sans can't live together) "hello how's ye been my little sea?" You asked you always called her sea or beauty as a nickname, sans became even more jealous since he was not getting much attention.

You noticed his jealous face without him knowing and started to have a make out session with him making Coral giggle and Ocean stick is tounge out in disgust (on by the way Coral is a human siren instead of a skele siren like sans and Ocean is half skeleton half your species) it caught sans by surprise but kissed back completely forgetting that papyrus and the kids are there (I swear you act like Naj goth while sans acts like Naj palette).

End of flashback

And that's how you found out sans gets jealous it sort of annoyed you cause you thought that it was because sans did not trust you. You were snapped out of your thoughts when you heard a whistle from someone, you looked and saw it was sans and Coral, you smiled and called Ocean over "HEY MATEY YOUR FATHER IS HERE" you shouted since Ocean was keeping a look out on the top of the ships sails. Ocean waisted no time he went down and jumped in the water along with you to say hi to sans and Coral.

You hugged Coral first but picking her up by her arm pits and swirling her around making her giggle (ladies first), you saw that sans was getting jealous again so you kissed him and hugged him "hey sans" you whispered in his 'ear'
"Hm" he hummed (it auto corrected to humped 😂😂😂😂) in curiosity
"I've noticed ye have been jealous lately why is that?" You asked/ whispered, he flinched
"Could we talk about this after we get the kids to bed?" You nodded

Time skip to getting the kids to bed since sans and Coral are staying at your and Oceans ship

You pinned sans to the wall after you helped him to your room "why?"
"H-huh?"
" why have ye been jealous. DON'T YOU TRUST ME SANS YOU KNOW I'D NEVER CHEAT ON YE " you shouted while tears flowed down your face
"IT'S NOT YOU I DON'T TRUST IDIOT IT'S OTHER PEOPLE I DON'T TRUST" sans shouted back with tears on his face too
" Sans...... Ye know I would never cheat on ye and I won't ever leave you" You said calming down but with tears still on your face, you whipped sans' tears away. You stopped pinning him to the wall and instead you grabbed his waist and pulled him to your level while he wrapped his tail around your legs and his arms around your neck so he does not drop "I know I just...... I thought you got sick of me because of me being shy since I never got much proof that you love me because of work " he answered
"Oh ye want proof matey ~" you said in a seductive voice making sans blush.

And if the whole night all the kids could here was.....

"Ahhh captain more more!"

" mmm sans"

" faster harder "

"Nn as y-you wish"

"Captain"

" sans"

"I'm gonna cum"

" cum with me"

"AHHHH"
