Dispelling Worries, Dispelling Worries♡
Time rewound thirty minutes earlier. As I headed into the bathroom to shower, Mari didn't show it on the outside, but she was trembling all over. Only after the bathroom door clicked shut did she flop down into a chair, covering her face with both hands.
"Ughhh... Why does Kang Seo-yoon have to walk around naked like that..."
It was because her friend Seo-yoon was just too damn sexy. Not just those huge tits, but her slim waist, firm yet soft thighs. The glimpse of her snowy-white nape when she tousled her hair, the occasional peek at her ass crack. Things she'd brushed off as just "her tomboyish side" before her dick grew now tormented Mari.
This very morning, she'd completely forgotten about what we'd done last night and hugged me tight in her sleep. Those soft hands wrapped around my waist. When my hands brushed the soft belly exposed as her top rode up, my hazy, half-asleep mind snapped awake. Every inhale and exhale tickled the back of my neck with her breath, making the hairs on my body stand on end.
And above all... It's natural for a guy's cock to get hard in the morning from blood rushing to the spongy tissue upon waking. But with those two massive, soft mounds pressing against her back, Mari had no choice but to wake up early. If we'd kept lying there together, she wasn't sure what might've happened—she couldn't guarantee she wouldn't lose control. It felt like her brain had been hijacked by her lower half.
"Haa... Let's calm down."
Ignoring the shower's rushing water as best she could, Mari sat straight in the chair. She placed her hands primly on her thighs and took slow, deep breaths. Closing her eyes and focusing, the surrounding noises faded, and a quiet peace settled in.
"Fuu—"
It seemed like the raging erection might subside without much trouble, but... There's that saying that the human brain doesn't understand the concept of negation. Tell someone not to think of a gray elephant, and they'll think of it even more. In other words, the moment Mari tried not to think about sexy things...
The moment she tried to forget about the cock that looked ready to burst through her dolphin pants...

"Mari..."
"Hnnngh♡"
She jolted upright!!! She couldn't help but think lewd thoughts. Had she focused too deeply? The image flashed in her mind: me lying on the bed, chest fully exposed, panting as I called her name. Mari's cock sprang to full erection. It had softened briefly and shifted position, so as it swelled rapidly again, it tore through the leg hole of her shorts.
"Ah, ah..."
Veins bulging like it might explode any second, throbbing with every breath. "Haa... I was so close to succeeding."
Seeing her cock tenting her pants like it might rip them, she decided to just jerk off obediently. Good thing she'd bought condoms yesterday—cleanup would be easy. The vivid memories from last night meant no lube needed.
"Th-this is how you use it, right...?"
Careful not to tear the packaging, she opened it and, like I'd done yesterday, blew into it once before slowly rolling it onto the glans. The lube on her hands felt weird, but it helped it slide down smoothly. It stopped midway again, but as long as it didn't spill during orgasm, it was fine.
"Hng, hnnngh...♡"
Her cock, now sheathed in pink latex, trembled like it was about to burst. Afraid I'd hear from the bathroom, she clamped a hand over her mouth, but muffled moans still leaked through her fingers. Reaching out with her other hand to grip it, electricity shot from her cock, racing up her thighs, waist, back, and straight to her head.
"...!"
Whether misfortune or blessing, she didn't cum from just that stimulation, but it was so intense her fingertips tingled, every sensation on her skin turning to pleasure as all her nerves focused there. Combined with the hyper-focused memories from moments ago, Mari couldn't stop her hand.
"Haah, haaah♡"
This wasn't what she'd planned. She needed to finish quick while I showered, get dressed, and be ready to head out. A rational voice screamed in the corner of her mind, but it was swept away by waves of crashing pleasure. All that remained was the futanari ruled by her cock.
Pat, pat, pat— Clumsy but diligent, mimicking men's jerking motions, she soon felt ecstasy surging from the root.
"Cumming, cumming, cumming♡"
Her balls contracted tight for ejaculation, the swollen shaft dilating her urethra to shoot semen. Pre-cum had been oozing since she put on the condom, plenty of lube ready.
Spurt, spuuuurt!!! Semen blasted with enough force to pierce the condom, pooling heavily inside.
"Heuk, eeeek♡ Gonna get addicted...♡"
Spurt, spuuuur— "Haa, haa..."
Shuddering from toes to scalp, Mari panted roughly after her orgasm. Her mind blanked from the pleasure waves that had melted her brain moments ago. As she reached with trembling hands to remove the condom, something caught her eye.
"Huh?"
Black panties. Freshly discarded, inside out. She knew exactly whose they were. Realizing I'd left them there before showering, her cock—starting to soften after one load—sprang back to rigid attention.
Her mind calming a bit, she thought to remove the condom, clean up, and get dressed... but
"Hng, hnngh, hnnngh...♡"
The sight of my worn panties triggered a flashback to yesterday, her hand abandoning the condom to stroke again.
"It's Seo-yoon's fault! Teasing me with that body!"
The moment she'd said she'd give up her virginity if it was me, hugging from behind. The moment she'd stripped too, saying it'd be embarrassing if only Mari did. The moment her delicate fingers wrapped around Mari's cock.
"...♡"
All those moments too lovable to resist. Mari only snapped out of it after two more orgasms.
And back to the present. After three loads in a row, cool-headedness returned with a strange lethargy. 'Huh? This size should fit under a dress now?'
Her cock, slowly deflating but still stiff, seemed small enough from her earlier experience that a skirt wouldn't show. How it shrank so much then ballooned was a human body mystery, but it was possible.
So she'd been regulating her breathing, waiting for the erection to fade, when our eyes met as I emerged from the bathroom.
"Seriously, you okay?"
"Yeah...! I took care of it before we left, so it's fine!"
"Good. And... it's winter, so padding should cover it anyway."
The weather had plummeted overnight—from autumn-mild yesterday to midwinter today. I fitted a mask over Mari's sniffing nose, then put one on myself. Living together, if one of us caught a cold, we'd both suffer.
Cha Yu-hyun might worry too. Choi Ga-hyun was home studying for retakes, but Yu-hyun lived alone like us, no roommate. If she got sick, I'd have to visit. Looked like she'd gone running yesterday.
"You really wear that long padding forever."
"Yeah. Maybe buy one for the US trip."
"Oh, this year?"
"Grandma wants to see me. College done, time to visit and say hi."
We waddled onto the bus. It warmed up quick inside.
"Ugh, Seo-yoon... I'm hot..."
"Hang on. Sweat cooling now could make you actually catch a cold."
"Hiiing..."
Pouting, Mari cracked the window. The chill helped.
Thirty minutes later, we disembarked and entered the department store, shedding our padding.
"Haaah... Feels like I can breathe."
"Winter's great except the thick clothes wearing you out. Ughhh..."
The clock read noon. Lunchtime, but neither hungry, so shopping first.
"Which floor first?"
"Duh, start at 1F and spiral up?"
"Oh?"
We blinked at each other. Right, Mari loved shopping... This is when I really felt my past life as a guy.
Riding the escalator floor by floor with Mari, nothing caught our eye.
"Hmm, this one's iffy?"
"Where? Oh... Fine for home wear?"
"Too thin for outside?"
"Yeah, definitely see-through."
A white blouse seemed okay but too sheer for campus. By our target floor, we'd only bought comfy sneakers.
"Seo-yoon, you wear sneakers every day. Need variety to rotate."
"...Can't I just wear the same ones?"
"At least three: one washing, one wearing, one spare!"
Mari compared prices sharp, used coupons, swiped her card.
"...How much?"
"Cheaper than expected? See?"
"Whoa, really? How?"
"Hehe, a girl's got ways."
Shopping bags piling up, we reached our final destination.
"Ready?"
"Of course."
"Then, let's go...!"
9F. Women's lingerie.
Mari needed bras for her bigger chest; I wanted sports ones. Must-visit.
"Fuu..."
Entering with Mari, staff swarmed instantly.
"Oh my, such a perfect figure. Looking for a specific style?"
"Sports bras good for workouts?"
"Of course! This way?"
We exchanged nods. Solo battles from here...
"Hehe, we just got a model perfect for a customer with your stunning lines."
"I-is that so..."
Ah. Energy draining already. Just buy and bolt.
