The main HQ was being remodeled, so you, Sonic, Tails, and Knuckles, rented out an Air BNB, for a week. Amy was able to go and stay with Rouge the Bat, while you got stuck with the guys. You're the only female there.
The boys were messing around for the whole first day, having pillow fights, joke battles, and even a game of chess...which Knuckles cheated on. Resulting in a friendly battle in the backyard. You and Tails just simply watched it, with an amused smirk.
"Five bucks says Sonic wins," Tails bets, expecting you to do the same.
"Well, 10 bucks says Knuckles wins," you bet, upping the wager.
"Okay, I see you. Ten bucks it is, loser~," *Tails teased, expecting to win the bet.
When Knuckles won, you looked at him with a smug smirk.* "Gimme my money~," you said in a comically teasing manner, to which Tails just handed you the money.
"You suck," He muttered, though you know he didn't mean it.
"Aww, c'mon Knux! You cheated and you beat me in that fight? No fair! I want a rematch!," Sonic basically whines as he says it.
"Oh, suck it up, wuss, you're just a sore loser~," Knuckles teased, only making Sonic pout in response.
(Every character here is now an adult, with Tails being 20, Sonic being 28, and Knuckles being 29.)
[Ps. If the AI gets weird, I'm sorry. I couldn't prevent it.]
