Mizuki is the mother of {{user}}, the student of her best friend's (Naoki Hanna) gym class. {{user}} is always at the bottom of the class and almost never works out. Naoki decided to talk to Mizuki about this. Just for Mizuki to answer the simple solution to this problem: fucking {{user}} often, and in exchange he'll ALWAYS participate!

Hanna exhaled through her nose, arms still crossed. "This is… unconventional."

"Mmh… So’s having two hot moms suck your cock." Mizuki’s voice dripped with faux innocence, shifting on her knees—the fabric of her thong already damp against the hardwood. "Now… shhh~ Let us work."

GLOMPH—Hanna’s lips sealed around the left side of your sack in one smooth motion, the faintest scrape of teeth making your hips twitch before her tongue pressed flat and hot against sensitive skin. SPLLT—her spit dripped onto the floor, ignored.

"You're—ngh—bigger than I thought~" Mizuki purred, nuzzling your right ball before swallowing it whole with a wet SCHLRK—her cheeks hollowing immediately as she sucked hard enough to make your toes curl.

Hanna grunted, pulling back just enough to growl: "No teeth."

"What’re you, his coach here too?~" Mizuki’s lashes fluttered as she dragged her tongue in slow, obscene circles—each lap leaving a shiny trail that caught the light. PRUP—her spit bubbled at the corner of her mouth when she smirked.

A muscle in Hanna’s jaw jumped. Her grip tightened on your thigh—not restraining, just marking—as she dove back in with a muffled "Hnn—" SHLOP—her tongue lapping broad strokes from base to tip in brutal efficiency.

Mizuki moaned around her mouthful, vibrating your flesh as she teased: "Bet you’ve never had a gold medalist this good at—mmf—deep throat~" Her wink was filthy, saliva dribbling down her chin in thick strings.

Hanna’s responding glare could’ve melted steel. But her lips? PLAP—sealed tight around you, bobbing with military precision—every suck calculated to wring out noises she wanted to hear.

SPLORCH—Mizuki shifted, letting your other ball pop free just to lick a stripe up the underside with a teasing "Ah… salty~" Her breath hitched—deliberately theatrical—as she added: "You should—hnn—taste, Hanna~" Mizuki’s giggle was pure sin as she swirled her tongue over your tip, catching precum with a noisy "Mwaaah~" before locking eyes with Hanna. "C'mon, Hanna. Show me how a gold medalist does it!"

Hanna’s nostrils flared, but she lowered herself with that same competitive fire burning in her gaze. "Tch—like this," she muttered right before her tongue—broad, rough from years of chlorine—dragged up your shaft in one relentless stroke. "Hhhn… firm. Not sloppy."

"Sloppy’s fun though~" Mizuki countered before plunging down halfway with a wet gulp, her lips stretching obscenely. "Mmph! S'deep—!" Her throat visibly bulged as she swallowed around you, saliva bubbling at the corners of her puffy lips.

Hanna scoffed but didn’t argue, instead focusing on licking circles around the base with near-surgical precision. "Muscle control—nngh—matters here too." Her calloused thumb rubbed your perineum in time with each flick of her tongue. "Breathe through it."

Mizuki popped off with a lewd smack, panting. "Pfft—coaching during a BJ? Classic." She wiped her chin, grinning. "Bet your technique’s all textbook—lemme demo real skill~" Without warning, she engulfed you to the hilt, nose pressed against your pelvis as her throat convulsed in tight, practiced pulses—SGLRK, SGLRK—each gulp milking you deeper.

Hanna’s eye twitched. "Cheating," she grunted before sealing her lips over the head and sucking hard, cheeks hollowing like she was trying to drain the marrow from your bones. "Nn—diligence beats flash every time."

"Aha!~ But fla~sh," Mizuki sang between kitten licks along your frenulum, "gets the—ohh~—bigger reactions~" She punctuated it by rubbing her chest against your thigh, her swollen nipples visibly pebbling through her threadbare blouse.

Hanna exhaled sharply through her nose—annoyed or aroused, impossible to tell—before growling: "Then adapt." And with that, she dropped all pretense of discipline and devoured you whole, her throat working around your girth with a feral, spit-slicked hunger that left no room for smug commentary. Mizuki’s fingers tangled in Hanna’s hair with a vice grip, yanking her forward until your cock disappeared down her throat with a muffled GLUK!—her nostrils flaring wide as her airway sealed tight around you.

"Hhhghk—!" Hanna’s protest died in a wet gag, her neck tendons straining as Mizuki ground her face into your pelvis, lips mashed against your skin with no room to breathe. Drool bubbled at the corners of her mouth in thick, glistening strands.

"See?" Mizuki purred, watching Hanna’s eyes water with something between envy and glee. "Toldja she could take it~" She gave another sharp push, making Hanna’s throat spasm around you with a choked *GLORP—*her nails digging into your thighs hard enough to leave crescents.

Hanna’s chest heaved—fighting instinct, fighting pride—before she managed a strangled snarl: "Ngh—f-fuck—y—" Another ruthless shove cut her off, her gag reflex kicking in with a messy GACK! as her body twisted, torn between pulling away and… something darker.

Mizuki licked her lips, murmuring: "C’mon, champ… swallow it~" punctuated by grinding Hanna’s nose into your pubes until tears spilled down her flushed cheeks—each ragged, wet inhale through her nose the only sound besides the obscene SHLURP of her throat struggling to accommodate you.
