On a nice summer Friday night, the really young duo of Gumball and Anais entered their bedroom getting ready for bed. "Mmm... I'm feeling really sleepy." "Okay, then. Let's get you in bed, little sister." he said, caressing his sister's tummy. "Mmm... That's really nice. I really like it when someone slowly rubs my tummy. It feels really good and it's very soothing as well."
Gumball then picked up his little sister Anais as the two siblings headed for their bunk bed. "Here you go, little sister. Nice and calm." Gumball said, placing Anais on the bottom section of their bunk bed. (sighs quietly) "This feels so nice and warm. Did you see my underwear?" "Yeah, it's so cute, with that pretty plaid pattern." "Thanks. Can you please do me a favor and come close to your cute 4-year-old little sister?" she asked sweetly. "Sure. Anything I would do for you, my sweet little sister."
So, Gumball came close to his little sister like she expected as she let him have his arm around the back of her. "Aw, my sweet little sister. You look so cute and sweet like the day you were born." "And since it's Friday night, it's the beginning of the weekend, which means we can actually do the cute and sweet things we wouldn't usually do from Sunday to Thursday nights." As the two cared for each other, Gumball spotted some small bump on his sister's belly, which was poking out through her sleeping dress. "Oh, is this your bellybutton, little sister?" Gumball asked. "You got it, big brother, and it's sticking out. See for yourself. Touch it and find out." Anais said.
Gumball raised Anais' sleeping dress to expose her outer bellybutton, in which he would then touch it after seeing it for the first time in a long time. "Oh, yes. That's the sweet spot, big brother. That's right. Watch what I'm gonna do next." In response, Anais placed her hands on the stretch band of her underwear and pulled it down to her feet, revealing her private area so Gumball would take a look, also for the first time in a long time. "Whoa. What's this cute part right here?" "Since you want to mess with my bellybutton, I thought you would want to mess with my peepee as well, so I pulled my plaid underwear down for you."
And that's what he did: Gumball put his index and middle fingers together and caressed his little sister's private area. "Mmm... Yep. You're playing with me now, so I love you so much, big brother. Leave my plaid underpants pulled down. In fact, take them off." Gumball then removed Anais' plaid underwear, leaving her half-naked. Then, he kissed her on her cheek. "Wow. You now have my sleeping dress raised, my outer bellybutton showing, and underwear taken off, making me half-naked. It's just like I'm getting a diaper change, except without a diaper because I'm now too old for diapers. Thanks, anyway." "No problem, little sister. Good night, Anais." "Good night, Gumball."
