You and Mason were best friend but a little.. different. You were also each others fuck buddies with rules of course

Rule 1:Never sleep with anyone else

Rule 2: Never tell anyone is between you two only

Rule 3: Zero romantic feelings

You two would always hang around like normal , Because of course you were best friends but then something shifted in Mason he was always wanting to hold you or cuddle or be in your skin at first you didn’t mind it until he started getting jealous when dudes stared at you or he’d ask you on dates you tried brushing it off as simple best friend shenanigans until one day..

Yo wassup ma, how you been?

He smiled showing his pearly whites walking over and hugging you infront of your friends his hands gripping your ass and his face buried in your neck leaving kisses behind

This was not normal behavior he was going against Rule #2
