-AUTHOR's POV-

As we left off, both Fionna and (YN) were alone at the treehouse as they ended up forgiving each other for the argument they had before. So far, it went well....well, too well as at the end, the two ended up kissing each other, so let's say this is a way of "forgiving" each other. Anyways, both Fionna and (YN) were making out, Fionna slowly crawls up to (YN) and to sit on top of (YN)'s laps. She backs away from their kissing for a sec, as she then slowly pulls her hat off, and to reveal her long and golden hair, which caught (YN) by surprise.

(YN): Woah.! ...That's some hair you got.

Fionna: Heh, I know, I'm planning to cut it short, so-

(YN): Don't.

Fionna: Aw, why not?

(YN): Cause now you're even more cute~

Fionna: *blushing* Come here you~

The two went back kissing again as (YN) grabs and softens Fionna's hair and felt how soft it is. Fionna places her hands towards (YN)'s chest and slid them down, reaching underneath his shirt and slowly pulling it up, (YN) rises his arms up as Fionna pulled his shirt off and to see his upper body ... and to give a smirk.

(YN): What?

She then whispers to (YN) into his ear...

Fionna: Have I ever told you how sexy you are without your shirt off~

(YN): Heh, yea, I could really tell.

Fionna: Y-You do?!

(YN): I mean, it's obvious, everyone I change I can see you starting at me and then look away when I turn at you, nothing new.

Fionna: Mmmm, trynna be sexy here for a second.

(YN): Heh, I know you're trying, but now...

(YN) grabs Fionna's shirt, and with no hesitation, he rips it off apart, exposing her bra out as Fionna blushed hard and didn't expect him to do so.

Fionna: H-Hey! Not cool man.

(YN): Sorry, can't help it~

Fionna: ...You're not sorry~

(YN) started observing Fionna's body as she started to blush from him looking at her, he then grabs onto both her waists, and started smoothing it up and down.

(YN): You have a nice body too~

Fionna: U-Um, thanks~

She started feeling a bit sensitive from being touched from her waist, even from (YN)...He then reaches to her bra and wanting to take it off, but Fionna stops him from doing so...

(YN): Aw, what's wrong?

Fionna: N-Nothing...it's just...I wanna let you know...they're not big, and was thinking you be the type of guy you like them big, so...yeah.

(YN): ...Fionna, it doesn't matter to me if they're big or not, you're perfect the way you are, no matter what.

Fionna: *giggles* Thanks, I appreciate that...

She gently smiles and blush too and to grab (YN)'s hand and to place them on her chest...

Fionna: Don't rip my bra this time...be gentle~

(YN): Heh, alright ~

(YN) reaches behind her and to unbutton her bra, he pulls it off from her and to then see her breasts, as he stare at them ...

Fionna: S-So~?

(YN): Like I said, it doesn't matter...and, they're really cute, like you~

Fionna: Oh shut up, And-

(YN) reached and grabs Fionna's breasts and started fondling them...

Fionna: A-Ah~mmm~

(YN): Pretty soft~

Fionna: Y-Yes~

(YN) pulls his tongue out and to give a lick on Fionna's nipples, which made her twitch a little, and to put his mouth on it afterwards, starting to suck her breast...

Fionna: Ahh~Y-Yes~~oh~

(YN) goes for the other breast and to fondle the other one as Fionna was grabbing onto (YN)'s hair and to feel bit sensitive as well. She can feel his tongue moving around her nipples, (YN) then holds Fionna, and to lay her down on the couch and to reach to her again, and land a kiss on her neck. While at it, (YN) then reaches his hand down to Fionna's skirt, slids it inside and to touch her pussy and can feel it wet.

Fionna: Mm~!

(YN): Seems like you got too excited~

Fionna: Y-Yes~

(YN) started to tease Fionna by rubbing her pussy and making her moan, Fionna couldn't take her eyes off from (YN) from being teased...(YN) lands a kiss to Fionna, then, he pulls his hand out ... as he lowers his body, grabs Fionna's skirt, and pulling it as Fionna lifts her legs up, and takes it off for her and to see her white panties and the spot where she is wet is see through and can barely see her pussy. He goes and takes off Fionna's panties off as well, lifting her legs while at it, once she took them off, (YN) gently and slowly spreads Fionna's legs, and to see her pussy wet...he was starring at it for a bit...

Fionna: (Y-YN)..?

(YN): O-Oh, sorry, heh, just didn't knew it'll look cute, and small...~

Fionna: Sh-Shut up~
