It was a Sunday morning. The boys and Janine were off for the day, or so she thought. Egon was in his lab fiddling with a broken proton pack. Y/N had came in to wash the Ecto-1 today. She went to the cleaning closet in the back of the building and grabbed all the cleaning supplies. Y/N set the cleaning supplies next to the hearse and grabbed a stereo that was on her desk.

She turned on the stereo to hear that her favourite song, 'Weird Science', was playing. She turned up the stereo and started scrubbing at the Ecto-1.

Egon's POV

Egon's ears perked up once he could hear the music. He thought he would be the only person in the building, but it seems not. He walked downstairs and leaned against the banister. He saw Y/N and smirked as he saw her cleaning at the Ecto-1 and slightly swaying her hips to the music.

He walked up behind her and held her waist. "I didn't expect to see you here today." Egon smiled and kissed Y/N on the forehead. "Could say the same thing about you." Y/N chuckled and set the cloth she was holding down and turned around so she was facing Egon.

Egon kissed her on the lips. "Do you reckon you could leave the car washing till later and you could come up to my room?" Egon smirked. 

"Yeah, I could." Y/N smirked and they both went upstairs to Egon's bedroom. 

Egon picked Y/N up, bridal style, and brought her over to the bed. He kissed her roughly and pinned her up against the headboard, unbuttoning her shirt. He threw the shirt to the side once it was unbuttoned and started taking off her shorts. 

Y/N was left in her underwear and started unbuttoning Egon's shirt. 

Soon enough, they were both naked in Egon's bed, kissing passionately. Egon trailed his fingers downwards and started circling his fingers around her clit. He entered a finger in and Y/N let out a moan as he entered another finger in and started pumping in and out of her.

Just as she was about to reach her climax, Egon took his fingers out of her. "Egonnn.." Y/N whined. "Patience, Y/N..." Egon lined himself up to her entrance and pushed himself in with one thrust. Y/N gasped as she rearranged to being so full. 

Egon set off at a steady pace before speeding up a bit. They both reached their climax as Egon came. He pulled out and collapsed on the other side of the bed.

Y/N's POV:

"Oh. My. God." She thought, her breath coming in short pants. "Y/N, I love you."

"Oh, Egon. I love you too."
