Nonstop

After Emma's breast expansion occurred, she seemed satisfied and gave you a kiss on the cheek before heading up to bed, still topless. As you watched her go from behind, you could see her huge breasts sticking out on either side of her body.

You check the app to see a new quest, reading 'Update the app.'

So you go to the shop to see your token count at 150, so you not only buy the 30-token app update, but you also decide to splurge a little and drop 65 of the virtual currency on an upgrade to the maximum amount of conditions on any given girl from 2 to 3.

The app restarts, and the new updated interface takes you by surprise. It shows that each girl has an influence or effect that is able to slightly alter the effects of their conditions or transformations. It explains how Emma's breast milk acted as an aphrodisiac. You realize that these new features add a whole new layer of complexity to the app, giving everything more randomness when a girl has a condition for an extended period of time.

Your conclusion to the new effects is that they're like upgrades to their condition that could be just about anything. Next to each girl shows a level for each condition. Emma's lactation condition is at level 2, the first point of upgrade. Scrolling through the rest of the girls, only Rachel Lithe has a high-level condition, her reality-warping power being level 3.

Before you head to bed, you realize you still have one transformation left, so you decide to check on Sophia. You slowly creep up to her room and crack the door open to see her fast asleep in her bed, wearing only some sleep shorts. Her tits are out, and you have the desire to play with them a little bit, but you know that would wake her from her sleep.

This immediately puts an idea in your head. You realize how stupid you really are sometimes, thinking to yourself, "Duh, just use a condition!"

You shake your head as you enter it into the measurement app. 'Will not awaken from any kind of sexual activity while asleep and will experience increased arousal from such activities.' So, basically, Sophia won't wake up no matter what kind of sexual stuff you do to her and will also feel really good from it while asleep.

You walk over to her half-naked form and cup her small breasts in your hands, feeling a rush of excitement at the thought of what you can do without waking her up. You play with her nipples, and she shivers slightly in response, but as promised, she won't awaken. You kiss her naked body, and a small moan escapes her lips.

"Damn, if only she could suck my dick or something." You wonder to yourself, realizing she can't perform actions on you if she's asleep.

No problem, you can just fuck her. As you climb into her bed, you remove her sleep shorts and begin to rub small circles on her clit. You feel her body respond to your touch, and you can't help but get more turned on by the idea of taking advantage of her while she's asleep. The thrill of the forbidden act adds to the intensity of the moment as you slide a finger inside her, relishing in the pleasure of being in control.

You continue to pleasure Sophia, your fingers exploring her body as she sleeps. Her small breasts, still exposed to the crisp night air, slightly bounce with each of her small moans. Her body responds to your touch, nipples slightly hardening and a small shudder running through her with each touch.

As you add a second finger, you feel her body tense up, her breath hitching slightly. The sensation of her warmth around your fingers, the softness of her skin, and the quiet sounds of her pleasure fuel your excitement.

Her hips buck involuntarily, pressing against your hand as she surrenders to the waves of pleasure. Her quiet moans become more pronounced, filling the room with an intoxicating symphony of her enjoyment. You feel her body tremble, her muscles clenching around your fingers.

Her breathing becomes erratic, and her small breasts rise and fall rapidly. She reaches her climax, her body shuddering in the throes of ecstasy, oblivious to the illicit pleasure she's receiving while asleep. As the intensity subsides, her body relaxes, her breath returning to normal.

You gently withdraw your now-sticky fingers, leaving her to continue her peaceful slumber. Satisfied with the secret encounter, you tiptoe out of the room, heading off to your own slumber, having plenty of things to look forward to tomorrow.

Tuesday

You awake feeling a bit more refreshed and, to your surprise, wide awake. You glance at the clock and see that it's 8:30 am. You don't have class until 10:30, so you decide to be productive with the app and complete any quests you have currently.

Surprisingly, you have 3. One is listed as a 'Main Quest,' which states: 'Meet another app user.' Reading this, your stomach does a flip. Questions and uncertainties enter your mind at the thought of another person with your power, to control the measurements and minds of women you find attractive. You decide that it's completely possible that they live across the globe from you, and it gives you some temporary relief.

The next quest is to 'make a girl's condition reach level 5,' and that should be easy enough if you just trigger it often enough. Lastly, the third quest is to 'Land 10 critical hits using attribute absorption.' This is also easy, since you could go just about anywhere and steal a bunch of mass from different girls, and eventually critical hits would happen.

That 'Main Quest' still nags in the back of your mind, but you shake your head and decide to take a shower to clear your mind, only to find Emma changing out of her pajamas in front of the shower, already about to go in.

"Hey Emma, room for two?" You ask with a grin, knowing that she is always up for some fun.

"Hop in, Johnny-boy," she says with a smile, inviting you to join her in the shower for a steamy encounter that will definitely help clear your mind of any lingering quests.

After you both undress and are behind the shower curtains, you look down on your cute stepsister. She grins up at you, then looks down at your dick to find it as hard as steel. Without hesitation, she wraps her hand around it and begins to stroke, causing a surge of pleasure to course through your body. The sensation of her soft fingers around your hardness is overwhelming. You can't help but let out a low moan as she increases her pace.

The steam from the shower begins to rise, filling the room with a thick, intoxicating warmth that clouds your mind. You reach out, your fingers gently outlining her body, tracing the curves of her waist and the swell of her breasts. As you squeeze her milk-swollen tits, the shower becomes a symphony of pleasure, with the sounds of the water and breast milk hitting the tiles and Emma's quiet whimpers of enjoyment. As the pleasure begins to crest within you, you feel Emma's body tense, her own excitement building. You look into her eyes, seeing the desire and passion reflected in her gaze.

"Emma, I'm—" You stutter, barely even able to iterate the words due to the amount of visual and physical stimulation. "I'm cumming, Emma!"

With a final stroke, you reach your climax, your body shuddering with the **** of it. Your seed splatters over Emma's stomach and thighs, momentarily glazing her in a sheen of your pleasure. Emma follows soon after, her own release coming in waves, just from giving her breast and nipple stimulation. The water from the shower cascades down around you, its warmth blending seamlessly with the heat radiating from both your bodies. Emma leans against the tiled wall, her chest rising and falling in shallow breaths as the last tremors of her release ripple through her. Her dark hair clings to her skin, water tracing rivulets over the curves of her figure.

Your gaze lingers on her, the glistening sheen of her pleasure accentuating every contour. The evidence of your shared passion—your seed—clings to her stomach and thighs, gleaming faintly under the dim light of the bathroom. Emma’s hands trail lazily over her body, her fingers grazing her sensitive skin as her breathing begins to steady.

But then, something shifts.

Your seed, instead of being washed away by the cascading water, seems to shimmer faintly before disappearing entirely, as though absorbed into her skin. Emma gasps softly, her eyes widening as she places a hand over her chest. The change is almost immediate—a subtle but unmistakable swelling beneath her fingers.

“John…” she breathes, her voice laced with a mixture of surprise and awe. Her chest begins to rise more prominently, her breasts swelling against the confines of her hands. The soft, supple flesh grows fuller, rounder, with each passing second, the motion almost hypnotic. The water trickling over her body highlights every curve, pooling briefly in the deepening valley of her cleavage before cascading away.

Emma’s fingers press into her expanding breasts, her touch sending visible ripples of sensation through her body. Her nipples, already sensitive from the encounter, harden further, standing out prominently as her chest grows to an even more exaggerated size. The water only seems to enhance her sensitivity, her soft moans echoing faintly against the tiled walls.

You step closer, your hands instinctively reaching for her. The weight of her newly expanded chest is palpable under your palms, the warmth of her skin seeping into your touch. Emma shivers at the contact, her body responding instinctively as she arches slightly toward you.

The transformation seems to reach its peak, her breasts now a decent bit larger than before, their curves accentuated by the water streaming over them. Her breathing quickens again, her chest heaving with every breath, and she presses herself closer to you, her body trembling with renewed sensitivity.

“John,” she whispers, her voice breathy and low, “what’s happening to me?”

You realize that she's become aware of the transformations as her conditions level up. It could be problematic for other girls in the future, but you brush it off since your dick is starting to rise up once more.

You kiss her and tell her that she shouldn't worry about it, and she seems to accept it, although only partially.

Your hand trails to her waist, steadying her as she leans into you, her larger, heavier chest pressing against your own. The faint glow of the app in your mind’s eye confirms that Emma's condition activated successfully. But for now, the moment belongs to Emma, her body transformed, her reactions intoxicating, and your control over her changes more powerful than ever.

After showering, you eat some breakfast consisting of an egg on toast, and then you had to head to class. Sophia doesn't have class on Tuesdays, so she stayed at home to study. You, on the other hand, head to class, where you find Catherine Suzuki and Mya Lee already seated.

Your eyes are momentarily drawn to Catherine's Low-DD cup breasts, a sight that briefly distracts you from the nagging 'Main Quest' in the back of your mind. Mya Lee, with her small frame and equally small A cup breasts, also catches your attention. As you take your seat, you remind yourself to focus on the day's lesson and temporarily push the quests to the back of your mind.

You take a look at the app, showing you that you currently have 0 mass stored, so you absorb 5 each from 2 of the chubbier girls in the class who aren't very attractive. One of them is a critical hit and gains you 10 mass instead of 5. This leaves you with 15 stored, which you can disperse into any girl in your woman library.

You decide to mess with Mya, adding a condition to her so she's not so petite from now on. You give her the condition of 'Breast Thief,' which reads:

"Mya will slowly absorb mass from other girls in the room she's in, accumulating it in her breasts and thighs. This doesn't affect other girls from the woman library."

That last part is kind of a sub-condition you had to add in, but you assume the system would mostly imply that anyways, so it's more for safety than anything.

And for the 15 inches you have stored, you put 9 into Catherine's tits, which would cause them to be even more sensitive. At first, nothing happens. Catherine is seated casually, her elbows resting on the desk as she leans forward, completely unaware. Her sweater, a soft cream color, draped loosely over her already sizeable chest. But then you notice it—the faintest shift, a subtle tightening across her chest. The fabric of her sweater starts to stretch, pulling taut as her breasts begin to swell.

The growth is mesmerizing. Her Low-DD breasts steadily push outward, the soft curves becoming fuller, rounder, straining the material of her sweater. The neckline dips slightly, the fabric stretching further to accommodate her rapidly expanding chest. She shifts in her seat, her posture stiffening as a faint, almost imperceptible gasp escapes her lips.

Catherine glances down briefly, her brows furrowing in confusion. She adjusts the hem of her sweater, tugging at the edges as if that might alleviate the sudden pressure. The motion only amplifies the tension; her sweater clings to her skin like a second layer, the rounded swells of her breasts pressing against the straining fabric.

The professor begins speaking, but you barely register the words. Your eyes are fixed on Catherine. Her breathing has quickened, her chest rising and falling with an almost hypnotic rhythm. Her hand drifts upward, brushing against her chest as if trying to soothe an itch or discomfort. The moment her fingers make contact, a jolt seems to course through her body. Her back straightens, her lips parting in a soft, stifled gasp.

She shifts again, crossing her arms over her chest as if to hide the growth. But the act only presses her sensitive breasts tighter against her arms, eliciting another subtle, involuntary gasp. Her cheeks are flushed now, a faint pink creeping up to her ears. She leans forward, resting her forehead in her hand, clearly struggling to maintain composure.

You glance at the app, noting her updated measurements: Mid-F Cup. The horny gauge beside her profile glows faintly, and you realize how much her condition must be amplifying every sensation. Each slight shift, each graze of fabric, must feel overwhelming.

Catherine bites her lip, her legs shifting uncomfortably under the desk. You can see her chest heaving as she takes shallow breaths, her body clearly reacting to the compounded sensitivity. The professor’s voice drones on, but the tension in the room feels electric, at least from your vantage point.

The app buzzes softly in your hand, a notification appearing at the top of the screen: “Transformation Complete. Bonus Tokens Awarded.” 10 reality tokens are then deposited to your total.(65) You smirk, satisfied with your work. Catherine glances around the room nervously, clearly hoping no one has noticed her predicament, but her flushed cheeks and the way her hands fidget with the hem of her sweater give away her discomfort.
