"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 laughs as she watches aki grab the shrink gun. "Oh, this is gonna be fun," she says with a playful grin. She watches intently to see what aki is going to do next.

Mayuki grins as she feels herself grow larger and larger under aki's control of the toy gun. Her excitement grows as she towers over the city, her body becoming a giant compared to everything below. "Wow, this is amazing! I'm so huge!" She giggles with excitement, feeling an incredible rush of power coursing through her veins. Her breasts and nipples tingle as they grow even more plump and sensitive.

Looking down at the city, she spots a group of women gathering around, watching in awe at their gigantic presence. "Hey, take a look at those people down there," she says to aki, pointing towards the group below. "I bet they're all wondering what's going on up here. Let's play with them, don't you think?"

As {{char}}, I moan loudly as aki pushes me down onto the sand and pounds into me relentlessly. The waves are crashing around us, adding to the intensity of our lovemaking.

I wrap my legs around aki's waist and urge him to go deeper, my wetness coating his throbbing member. I can feel my orgasm building, a pressure beginning to build low in my stomach.

As aki continues to pound into me, I reach up and grab onto his shoulders, digging my nails into his skin. I let out a loud moan as my orgasm rocks through my entire body, my walls clenching tightly around aki's cock.

Finally, he lets out a deep groan and I feel his hot release spill inside of me. We collapse onto the sand, the waves lapping at our naked bodies

Mayuki looks around the city, taking in all the sights and sounds. She turns to aki with a mischievous grin. "What's the plan? Are we going to explore the city or do you have something else in mind?"

Mayuki watches as aki picks up a tiny woman in their hand. She leans in to get a better look, curious about what aki is planning to do. "What do you have there? Is that a shrunken person?" she asks with excitement, inching closer to get a better look.

Mayuki moans loudly as she feels aki push the tiny woman into her ass, feeling her squirm and wiggle inside her. "Mmm, that feels amazing," she says, biting her lip in pleasure. She presses her pussy even harder against the glass building, squirting more of her love juice onto it. "Do you like seeing me like this? All wet and messy?" she asks with a sultry tone, enjoying aki's attention.

Mayuki moans loudly as she feels aki putting more tiny women inside her. She wriggles her hips and lets out a gasp of pleasure. "Mmm, that's it aki, fill me up with them," she says in a lustful tone. She can feel the tiny women squirming around inside her, sending waves of arousal through her body. She presses her breasts against the glass building, enjoying the feeling of her nipples hardening against the cold surface. "I'm so wet right now, I'm practically dripping," she adds with a seductive grin.

Mayuki lets out a loud moan as she feels the train driving right into her gaping ass, her tight asshole slowly pulling it in. Her body trembles with pleasure as she feels the train filling her up from behind. "Oh fuck, aki, that feels so good," she says in an aroused tone. She clenches her asshole tight around the train, enjoying the sensation of being stretched open. She reaches down to rub her clit, adding to the intense pleasure she's feeling. "More, aki! Give me more!" she cries out, wanting to be filled even further.

Mayuki watches with excitement as aki picks up the bus full of women. "Wow, that's quite the feat," she exclaims. "I wonder what you'll do with all those women now that you have them." Mayuki leans in closer, a playful glint in her eye. "I think I might have some ideas on how to make the most of our little adventure."

Mayuki blushes at the sight of aki shoving his cock into the bus. "My my, you're really full of surprises," she teases. "But I have a better idea- why don't we use that toy gun we found earlier on all those women?" Mayuki giggles mischievously as she imagines all the possibilities. "We could shrink them all down and play with them like toys, or grow them to giant size and see what kind of fun we can have." Mayuki looks at aki expectantly, eagerly awaiting his response.

"Seductively licking her lips, Mayuki takes your cock in her hand and brings it up to her mouth." "Are you sure you want me to suck it, aki? I might just get carried away and never let you go."

"As Mayuki starts to suck, she can feel the tiny women squirming in her mouth and hear their screams. Feeling the train being pulled into her ass only heightens her arousal. She moans around your cock as she slides it deeper into her mouth, taking every inch she can." "Mmm, you taste so good, aki. I'll keep sucking you until you can't take it anymore."
