Biffa x Xisuma and others

Beneficial relationship?

This story is inspired of a incorrect quote
Xisumas POV
"Hey Biffa!" I shouted as I walked to the my Biffas room
"Hey X! What's up?" He said looking up from his screen
"Nothing.. what are you watching?" I asked and walked closer to him
"I'm watching something about a beneficial couple" he replied pausing the show and looking at me, then pulling me to sit on his lap causing me to heavily blush that was clearly visible though my helmet. Biffa and I have some kind of flirting fight going on, it all started when I fell and Biffa catched me and then winking at me. I decided to get revenge, and now this is like a war of flirting with each other that I'm not gonna win in! Biffa is a master when it comes to flirting and I actually prefers bottom so..
"W-what's a beneficial couple?" I asked still blushing like mad
"Uh- that's a special type of relationship.." he answers looking away from me
"Like us?" I asked still not knowing what beneficial means.
Biffa seemed to be suprised of my question, he looked down with a "deep-in-though" expression on his face, then looking at me with a confused smile
"Uh that's actually up to us" he said
"What does it mean to be beneficial?" I asked hoping to get a real answer
"Well a beneficial relationship means that you let out any kind of love interest or something like that" (I think)
I quickly realized what Biffa meant by "that's actually up to us"
"A-are we a beneficial couple?" I nervously asked
Biffa looked me in the eyes very deep down. Then he did something unexpected, he took off my helmet and brushed some hair out of my face
Then..
He kissed me.
Biffa kissed me
Biffa
Kissed
Me

I was blushing like never before, my face was all heated up and I was completely red. Biffa broke off the kiss "no, we're not.." he whispered in my ear sending a shiver down my spine. He kissed me again, this time shorter time but with more passion and confidence as he noticed how much I enjoyed it.
It felt like a dream to be honest, I've now realized how long time I've liked Biffa. It's a heavingly feeling of Biffas lips pressing against mine softly.
He kissed me multiple times, liking my bottom lip and slightly biting, just a little on my now abused lips. But that was fine, I just wanted this to last forever. He then stood up and asked
"Want an ice cream?"
"Yes! Thank you!" I said gratefully
Holy macaroni with cheese on top that felt good. I wanted that to happen again, so badly.
"I'm back!" A voice shouted at the door. It was Biffa with two ice creams. He came over and gave me one
"Thanks Biff" I thanked him
No proplem!" He said laying his ice cream in a double icecream holder on his counter. Then picking me up and sitting  on the chair I was sitting on, then placing me on his lap, giving me a kiss on the forehead, then he throws my helmet to the other side of the room and began to eat his icecream meanwhile I was trying to get words out
"Y-y'know.. I like having my helmet on.." I muffled after a bit
"I think you look cute without it" Biffa said lookin at me softly
"Is it because the helmet hides your blush~" he asked leaning closer making me blush again
"N-no of course not!" I shouted annoyingly even tho Biffa probably found it cute.
I just ate my ice cream, but it was a bit hard when you sit on another persons lap, and the person keeps moving and teasing you. I ended up having ice cream stains all over my face. Biffa just giggles.
"It's not funny!" I muffled looking away
"Yes it is" he answered leaning closer and licking the ice cream off my face turning me into a tomato.
Time skip
It is now 9 pm. Biffa and I have just been watching stuff but it's getting real late!
"Hmmmm.. I'm gonna go to bed Biff ok?" I said still on his lap eyes already closed
"Your sleeping here tonight" he responded like it was nothing
"Wh-wh-wha-" I didn't even finish my senstence when Biffa picked me up bride style and layed me on his bed, then laying down next to me, putting the covers on us and grabbing me by my waist and pulling me to snuggle with him
"Love ya Biff.." I said eyes closed
"Love you too X" he replied kissing me again
