"I told you, I just wanted to give you a little surprise! Besides,"

she giggles again, "it's not every day that my little brother gets to defeat such a mighty foe."

Her eyes sparkle with affection as she looks at you, making it obvious that she's genuinely proud of everything you've accomplished today. And even though you might not understand why she does some things sometimes, in this moment, you couldn't be happier to have her by your side.

"Now?" Gum says, tilting her head thoughtfully. "How about we take a break and get something to eat? I'm starving!"

She nudges you playfully, her appetite clearly on display. It seems like no matter where they are or what they're doing, food is always on Gum's mind. But then again, who could blame her? Food tastes better when it's shared with someone special, and there's no one else you'd rather share it with than your sister.

"...are about the size of cherries," she whispers, running her fingers over your sac before moving to cup one of your testicles gently in her palm. "And mine are more like grapefruits." Her voice trembles with desire as she feels the weight of her own massive balls against her thighs.

Her other hand finds its way back up to your hip, squeezing gently before sliding lower still until it reaches between your legs once again. "I've never... been this close to another person like this..."

The feel of your warmth against her fingers makes Gum shiver with desire. "Um... I-I don't know..." She stammers out, her voice trembling. "I've never actually seen my own cum or someone else's..." Her cheeks flush bright red as she admits this, and she looks away for a moment before glancing back up at you.

Her fingers brush against your shaft once more, feeling the heat and hardness of your cock through your boxers. "But...

"I..." She swallows heavily, her heart racing as she continues to touch you. "It's... so much bigger than yours." Her fingers begin to trace circles around the head of your cock through the fabric, making it twitch in response.

Her own arousal is building quickly now, and she can feel her dragon dick beginning to throb against her stomach as it grows harder and larger with each passing second. "I've never... been with someone so much smaller than me..."

Yes. You are really tiny. And I am huge.

**Paragraph 5**

Ahh~ T-Then... You can start by sucking on my dick. Her tail twitches again as she says this, pointing at her huge futa cock with a shy giggle. She blushes even deeper, biting down on her lower lip nervously as she waits for your reaction.

I've never done that before... With someone else, I mean. But I want you to be my first...

Aww sht.* She gasps, looking away in embarrassment. I'm sorry, I shouldn't have said that. It's not like I expected you to do that or anything! I just... really want your opinion on it. She stammers, trying to undo her jeans shorts with trembling hands. I-I don't know what to expect from guys... I've only ever seen guys like you drooling over other girls' tits and ass, but never actually wanting to finger fuck a girl who looked like me.

Her eyes widen as you push her back, your hand firmly gripping her shaft. She gasps when you position her cockhead at your entrance, feeling it press against something hard and smooth. Her hips jerk forward instinctively, wanting more contact.

Gum: Oh... Gods... I-I've never... Her words trail off into a moan as she feels you begin to push back against her.

Her eyes roll back in her head as you guide her cock into your body, the feeling unlike anything she's ever experienced before. The tightness surrounding her shaft combined with the warmth and strength of your muscles sends waves of pleasure coursing through her.

Gum: Ahhhh... So good... So tight... You feel so fucking amazing...

Her cheeks flushed even deeper at your bold request. She licked her lips nervously before glancing back down at you, eyes flicking between your face and your growing bulge in your shorts. Finally, she closed the distance between you and slowly lowered her massive balls towards your face.

"Here," she breathed, "but don't... don't tell anyone..." Her tail continued to thrust inside of her as she held her heavy testicles close to your face, offering them up for you to touch or taste.

You lean in and carefully take one of Gum's balls into your mouth, sucking on it gently at first before starting to move your head back and forth, teasing her sensitive skin with your tongue. She lets out a shuddery moan, her tail moving faster as she feels the sensation directly against her clit.

Her other hand comes up to rest on top of your head, guiding your movements as she enjoys the pleasure you're giving her.
