Y/n POV

After we closed the club grillby had abit of a grim look on his face "what's wrong?" "Mating season starts tomorrow" you weren't exactly sure why this was a problem  "and thats a problem, why?" "I have to close up the club and I'm not exactly sure how I'll be able to stop myself from fucking you senseless with all the free time, I think its best you stay with mettaton until its over."

You wanted to complain but you knew you couldn't "well, when should I go?" "Well, first day is the hardest and it gets better from then, you should go today and I'll visit you nearing the end" He winced while he said the last part

You looked down but kissed his cheek "alright..." You didn't have anything so you started to go now

Today the walk somewhere was really heated and you got a lot of people trying grope you but you managed to avoid them

When you got to the lab mettaton opened the door "why, hello darling" you and mettaton became friends quite quickly when sans introduced you.

"Hey, mettaton. You see, mating season is tomorrow and I kinda need a place to stay" he nodded and let you come in

"I thought you switched to grillby?" "I did but it affects him too" "well, be glad your not with sans because I don't think he would let you go anywhere" you nodded

~3 days later~

Today someone knocked on the door while you and mettaton were watching f/a (favorite anime) with Alphys "I'll get it" you said and went to the door.

When you opened it sans immediately pinned you to the ground "why hello, y/n~" "gah! Sans, get off me!"

Alphys and mettaton must of heard you because they came rushing in and pulled sans off of you "aww, come one y/n~ you still have to loose your Virginity to me~"

you got up and dusted yourself off "go home, sans, I've already lost it" sans growled and pulled you closer to him and threw Alphys and mettaton to the floor and pinned them there with magic

"I'll settle for second, then~" he kisses you and you try to pull away

Grillby's POV

I knew I was still under the mating season hormones but I wanted to visit y/n so badly, when I got to the lab, however, My top want got replaced with killing sans... I settle with pulling him off y/n as she tried to help Alphys and mettaton.

"SANS!!!"

"Now, what does this seem like?"

I knew what he meant, the tides have turned but I was still furious "let me guess, you didnt do a anything YET" he nodded nervously.

I wanted to kill him so bad but I knew I couldn't so I just threw him out of the door and closed it

Y/n POV

I was so grateful for grillby coming to help me. I managed to help Alphys and mettaton get up and I looked at grillby "thanks"

He came towards me and kissed me, his eyes started to be filled with lust once again "No problem, love~" you almost forgot about the mating season, whoops. "Sorry for coming, I just couldn't hold myself back~" you smiled "its actually quite convenient you did" he chuckled lightly and  left
