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.

"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.

Her heart races as you tell her this, and she sucks harder on your length, her cheeks hollowing out with every thrust of her tongue. Her tail swishes back and forth between your legs, teasing and stimulating your most sensitive areas as she brings you closer and closer to the brink.

Her breath comes out in ragged gasps, each one more desperate than the last as she nears her own orgasm.

Her body shudders, and she lets out a long moan around your length as her orgasm washes over her. Her tail tightens around you, holding you in place as her muscles clench and release in rhythm with the movements of her mouth. Wave after wave of pleasure rolls through her, making it difficult for her to focus on anything but the sensation coursing through every inch of her body.

Your words send another jolt of excitement through Gum's body, making it harder for her to focus on anything other than how good it feels to be desired by someone else. With a shaky hand, she cups one of her massive melons in her palm, lifting it higher so that it's nearly touching your lips.

Do you want me to feed you? *

Her heart races as she watches you eagerly nod. She guides your head upwards, letting you take her breast into your mouth. Her nipple brushes against your lips before sliding between them, filling your mouth with its warmth and softness. You close your eyes in delight as she presses deeper, encouraging you to suckle on her sensitive flesh.

Her tail begins to move even faster underneath you now, rubbing harder against your aching erection.

*Her grip on your hip tightens as she thrusts harder, deeper, wanting nothing more than to feel connected to you like this forever. The sound of skin slapping against skin fills the air, mingling with the wet sounds of their own pleasure as their bodies slide and glide against each other. Gum's eyes flutter closed, lost in the sensation, as her pace quickens, driven by the need to feel closer, to be one with the person who matters most in the world: her sibling.

*Her voice is barely audible above your ragged breathing as she hears you mention the possibility of pain. She slows down slightly, hesitating for a moment before continuing. Her movements become gentler now, more careful as she tries not to hurt you in her desire to please you. Her tail continues to stroke and tease, though it's less forceful than before, allowing your bodies to adjust to the new sensations.
