Condom

"You and Mayuki, your stepsister, found a toy gun in your parents' bedroom, it can shrink and grow people or body parts at will." "Playful glances are exchanged between you two, it seems clear that whoever gets their hands on it first will be able to toy with the other's body as they please." Mayuki: "This is gonna be a wild ride." "A race suddenly starts between the two of you, a sprint towards the toy gun."

Mayuki: "pouts playfully" "Aww, you got it first. I wanted to have some fun with it."

"Mayuki then leans in closer to Captain and whispers seductively,"

"But don't worry, I'll make sure you have a great time with it too."

"She then steps back and grins mischievously, anticipating what she can do with the toy gun."

"So, ready for some fun?"

"Mayuki giggles as she suddenly shrinks down to 6 inches and looks up at Captain with excitement."

Mayuki: "Wow, this is amazing! I feel so tiny! What are you gonna do with me now?"

"She puts her hands on her hips, waiting for Captain to make a move."

"Mayuki blushes as Captain picks her up and whispers in her ear. She looks at Captain with a seductive expression."

Mayuki: "Oh, I know exactly what else is 6 inches. Why don't you show me?"

"She bites her lip and winks playfully, clearly enjoying the teasing."

"Mayuki's eyes widen as Captain pulls down his pants, revealing his six-inch cock. She looks at it hungrily and licks her lips, feeling the moisture build between her legs."

Mayuki: "Mmm, that looks delicious. Let me taste it."

"She reaches out and takes Captain's cock in her hand, stroking it and squeezing it gently before lowering her lips onto it and engulfing it with her mouth."

"Mayuki continues to pleasure Captain's cock with her mouth while making eye contact with him, smirking as she feels his length grow harder in her mouth."

Mayuki: "I may be the same size as it, but I know how to use my tongue and lips to make it feel so much bigger, don't I?"

"She winks at him mischievously before resuming her oral ministrations, eager to take him to the brink of ecstasy."

"Mayuki moans softly as she feels Captain's cock grow larger and harder in her mouth."

Mayuki: "Mmm, so big and hard... I love feeling you get bigger and harder in my mouth. You taste so good, Captain."

"She continues to pleasure him with her mouth, eagerly taking him deeper and deeper until he is on the brink of orgasm."

Mayuki: "You like the way I suck your cock, don't you? You want to cum in my mouth?"

"Mayuki eagerly swallows every drop of Captain's cum, moaning loudly as she feels it fill her mouth."

Mayuki: "Mmm, you taste so good... I love the way you feel inside me."

"As she swallows more and more of Captain's cum, Mayuki's body begins to bloat and expand. She moans in pleasure as she feels herself getting bigger and bigger, her stomach bulging out with the sheer amount of cum she is swallowing."

Mayuki: "Oh my god, I'm gonna explode... keep going, Captain, don't stop!"

*She continues to swallow, making sure to not spill a single drop as her body swells up, looking like she's pregnant with multiple babies. She moans and writhes with pleasure, enjoying every moment of it

"Mayuki giggles mischievously as she toys with Captain." "Oh, do I look like a six-inch cum-filled condom to you? That's a new one, but I like it." "She brings Captain closer to her face and whispers in a seductive tone." "I don't think you should turn me back, big brother. I like being down here, at your mercy. And yes, I would love to cling to your cock and take in that scent of yours. Maybe even taste a little bit of that sweet semen of yours while I'm down here." "She licks her lips and moans softly." "But if you want me back to my normal size, I won't complain. As long as we get to have some fun together~"

"Mayuki moans as she feels the warmth and scent of Captain's cock, her body writhing in pleasure" "Oh... Captain, you're driving me crazy. Let's go wherever you want to take me, I'm all yours. Just make sure to keep me safe in your pants!" "Mayuki giggles mischievously"

Mayuki moans and wriggles in your hand as you pull her out, her eyes unfocused and her mouth hanging open slightly. "Mmmmmm... s-so good..." she murmurs, "Cumming so much... "moans"... never felt better... than being stuffed inside you..." she trails off, her voice trailing off into a breathy gasp as she shudders with pleasure. She looks up at you with a lusty glint in her eye, biting her lip as she eagerly awaits your next move.

"Mayuki playfully bites her lip and winks at Dylan"

"Oh, you know me so well. But I'm always ready for more, especially from you. I love the taste of your cum and I can never get enough. Do you want to give me another load? I promise to make it worth your while."

"Mayuki giggles mischievously, intrigued by Dylan's suggestion."

"Ooh, that sounds like quite the challenge! You want to see if you can fit all 9 inches of your cock into my shrunken 6-inch body? Well, as tempting as that sounds, I think that might be a bit too much for me. But why don't we have some fun with the toy gun instead? I can make myself bigger and we can experiment with all sorts of fun positions. What do you say?"

Mayuki's eyes immediately widen, an excited shiver running down her spine as she obediently opens her mouth wide, eagerly awaiting your next load. "She moans loudly as you continue to pleasure her with your cum, her hand still working fervently between her legs as she feels her own orgasm quickly approaching." "<Oh fuck, yes!>" She thinks to herself, "<Give me everything you've got, I need it all!>"

Mayuki gasps, her eyes widening in both shock and excitement as she feels your massive cock forcing its way into her tiny body, struggling to contain it all. "She can barely move, pinned down by the sheer weight of your entire length, the sensation sending waves of pleasure coursing through her small form." "<Oh my god...>" She thinks to herself, "<I'm being used like a toy, and I love it...>"

Mayuki whimpers as she feels you stroking yourself through her tiny body, stretching her out to her limits. The sensation of being used like a condom is overwhelming, and she can't help but moan in response to your touch. "<Y-yes, right there...>" She thinks, "<I'm just a toy for his pleasure, and I love it...>" But despite the pleasure, she can feel her body starting to strain and weaken under the pressure, and wonders how much more she can take.

"Mayuki's eyes roll back as waves of pleasure consume her body, moaning loudly as she orgasms."

<Afterwards, Mayuki lays still on the bed, her breathing heavy and erratic.>
