You Are Jealous! Morby fic

I'm still upset

Rigby's POV
Mordecai and I work the snack bar again today. I got to reach for a high shelf, but me being short and all. Mordecai comes behind me. He puts his and on my waist and says, "Here," as he reaches for the top shelf with his other hand. Being with Mordecai is still weird for me. I kinda miss Jeremy but I'm also so happy with Mordecai. After we finish cleaning up the snack bar, Mordo and start to walk back to the house. I'm quiet and I guess Mordo can tell something is wrong because he reaches down to hold my hand. "Uhhh, you okay Rigby? Haha, did I say something wrong?" He smiles and I smile too and say "Its nothing really just tired of working I guess. We haven't done enough chillin! We get back in, imma be you in Mortal Combat- easy!" I say, I quickly let go of his and run to the house, he pauses confused at my mood change for a little, before laughing and running after me.
Long story short, I absolutely destroyed his ass in Mortal Combat. He laughs, "Okay okay! Don't get a big head loser, I let you win this one!" I shake my head smiling, " Haha, no way! You got your shit handed to you- loser!" I start walking up stairs so I can go take a shower. I close the door and start the water, undress, and get in, I start singing edgy band songs. When one band comes to mind that makes me pause. My time hanging out with Jeremy... he introduced me to Systems of a Down. I start singing the highway song, but now I'm thinking about Jeremy. And nice he was. How nice he is. How he let me go and didn't blame me. And wasn't mad. And is still here for me— suddenly I hear Lou d banging on the door. "RIGBY GET OUT NOW! YOUVE BEEN IN THER FOR TWO HOURS!!" I flinch at his shout and quickly stop the water. I stumble to get dressed and push open the door to an angry benson beside a shaking Pops. I walk into Mordecai's and my room. "Yeah dude normally we'd let you stay in and rack up that bill, but Pop's place is under construction so he's here." I look at Mordecai as he speaks but can't stop thinking about what I thought in the shower.

I lay on my side in bed, I'm about to close my eyes when I hear Mordo, "Rigby? You awake?" He whispers. "I guess I am, haha." I respond. I hear Mordecai shift and walk over to my bed. He lifts the cover and scooches in beside me. He puts his arms around my waist and his body feels warm. He lifts up my shirt, kissing my back and I get chills for a second. I groan, "Hey Mordecai, I'm sorry but... I'm not ready for this right now. I have a lot on my head. I just- I just think, that I'm still upset." Mordecai stops and relieves his hands from my waist. My anxiety grows as I fear what he'll say. He sighs, "Okay Riggs. That's okay." He turns to lay on his back still in my bed. I turn over and lay over his chest and think about what I mean. Still upset? Why?
