NOTICE: In this fanfic, Finn and Flame princess are 17 years old; Just so you know.
Finn is walking alongside Flame princess in the night Woods. They've had a long day and were ready to hit the hay. "Hey, where should we stay tonight? My place or yours?" Flame princess asked. "Hmm, well your stabilizer coat is still in Laundry kingdom, so I'll stay at your place" Finn answered. Flame princess smiled "Okay!" "Oh, but let's stop at the Treehouse first, I wanna get my pillow". And so they went; after stopping by, they returned to Flame princess' home. "Okay, let's go in!" Finn started walking before FP stopped him "Wait silly! Geez, you always forget I have to put the spell on you first" "Oh, right" He laughed, a bit anxious. "Come closer…" Flame princess put her face near his, whispered the chant, then kissed him. She stayed like that for a while, making sure the spell took full effect. As she let go, Finn started to turn a shade of blue. "Rhombus, thanks" He never got tired of that. Ever since she learned the spell, things were going pretty swell for them.
They made their way inside. Finn got comfortable on the couch while Flame princess changed out of her usual clothes. "Hey FP, what movies do you have here?" "Umm, I think I have 'Heat Signature V'. I just borrowed it from LSP" She called out from the other room. "Can we watch it?" "Sure" Flame princess came out of her room wearing only a super long T-shirt, comfortable enough for cuddling over a movie. She snuggled next to Finn on the couch "Press play". In between making out and watching the movie, she fell asleep. Finn looked at the clock; It was really late "FP, hey, wake up" Finn whispered to her but she was sound asleep. He picked her up, and carried her to her room. He let her down on the bed and went to brush his teeth. "Fiinn…" he heard her groggy voice coming from the bed "Coming." He finished up and went to go lay beside her. They were face to face; 'Flame princess looks so cute while sleeping' is what Finn thought. She laid her head on top of his arm and hugged him, already in their usual comfortable position. Finn kissed her forehead one last time before drifting off to sleep…
