Let's Exchange Milk with the Master
The condom Lilith handed her looked different right from the start, material-wise.
“All the condoms we’ve sold so far were super thin, right?”
“Yeah... But this one’s pretty thick?”
“It’s not meant for insertion.”
She blew on it with a whoosh, figuring out the right direction.
Grabbing Rhea’s dick, where semen was dribbling out bit by bit, she slipped the condom over it like a sheath.
Even though it wasn’t erect, the condom clung perfectly.
It didn’t seem like it would slip off or fall down easily.
“When it’s leaking like this or during wet dream season, semen keeps trickling out nonstop, so we use a thick, high-viscosity material to catch it all.”
“I see...”
Rhea scratched her cheek and glanced down.
The liquid still oozing out through her urethra against her will felt a bit gross.
But at least it wouldn’t drip on the floor or stain anything else.
Lick, lick.
Lilith tilted her head after licking the semen off her hand.
“Not too uncomfortable, right? Some foreign object sensation is unavoidable.”
“Yeah... That’s fine, but...”
“But?”
“I need to pee...”
Rhea rubbed her legs together and looked up at Lilith.
For some reason, the urge hit right after putting on the condom.
She felt bad having to take it off so soon after Lilith had just put it on.
“Just go like that.”
“Sorry... Huh?”
“Just pee right there.”
Blink, blink.
Rhea blinked her big eyes.
Was she getting scolded for not asking sooner?
Poke.
Lilith’s finger jabbed her cheek.
“What do you take your master for?”
“I didn’t say anything...”
“Your eyes did.”
With a small sigh, Lilith moved behind her and placed both hands on Rhea’s lower belly.
“Your balls are overflowing with semen right now because they’re a little sore, so they’re in overdrive producing more sperm, got it?”
“Uh-huh... And?”
A little below her womb.
Her hands pressed and kneaded around the bladder, making Rhea’s back arch involuntarily.
Of course, with Lilith right behind her ass, there was no escaping her grip.
“That’s why wet dream condoms have a substance that promotes quicker ejaculation. Might as well drain it all out and normalize your sperm production rate.”
“Ngh, ngh...”
“But when you ejaculate a bunch like that, you kinda gotta pee too, right? That side effect we can’t fix, so that’s why you feel like you need to go now.”
Rhea nodded blankly at the plausible explanation.
All the while, she could feel her bladder filling up more and more.
“So just pee comfortably, okay? The condom’s thick enough to handle it too.”
“Nngh... But peeing in front of you is kinda embarrassing...”
“Huh? Everything embarrasses you. I’ve seen your dick flopping around, your asshole winking, you panting while clinging to customers, choking yourself trying to stuff it in your mouth—”
“O-okay! I’ll do it, so stop!”
She’d list every embarrassing moment from her first day as a succubus at this rate.
Ignoring the minor detail that it all happened in just one day.
Leaning slightly against Lilith, Rhea relaxed her urethra.
Trickle trickle trickle—
“There, there. Good girl, peeee...”
“Hngh... B-but I could’ve done this alone. Why are you...?”
“Huh? You’re cute like this. Gotta change the condom anyway.”
Half of her wanted to play up to the petting hand on her head.
The other half wanted to bolt to the bathroom right now.
Of course, that was just wishful thinking.
Squeeze.
Lilith had no intention of letting go of her lower belly.
“All out?”
“Y-yeah...”
She peed in front of Lilith until she felt empty and refreshed.
The condom had gotten noticeably heavy, but it didn’t slip or come off her dick at all.
“Alright, time for a fresh condom.”
“I feel like a baby getting her diaper changed...”
“Not far off, huh? No succubus gets praised for pissing herself at this age.”
“Nngh...”
“It’s fine. You’re new to being a succubus and a futanari, after all.”
Mwah.
Lilith kissed her cheek, then formed a ring with her fingers around the base of Rhea’s dick.
She pulled it down slowly, peeling off the condom that had been clinging tight.
Maybe because she’d just peed.
No semen came leaking out right away.
Gurgle.
Her balls were still making noises, so it wasn’t fully better yet.
“I’ll toss this and head upstairs, so wash your dick first. I’ll be right up to put a new one on.”
Lilith tied off the bloated condom casually and flipped the store’s [OPEN] sign to [CLOSED].
“Huh? What about the shop...?”
“Gotta take care of my kin when she’s sick. Otherwise, the other succubi will chew me out.”
“R-really...?”
Closing early for kin? Were they that precious?
She’d said most succubi shove their dicks in right after making kin...
“Even those types love their kin. They’re like kids born from their own essence—obviously precious. They just wanna fuck ‘em every day too.”
“I-I’ll go wash up!”
She bolted upstairs, not understanding that mindset at all.
“Whoa, that line was hot.”
“Eep...!”
Her dick twitched at the teasing, laughter-laced voice, and she dashed into the bathroom.
Not long after, the first-floor lights went out.
Lilith came up to the second floor right away.
“Rhea~ All clean?”
“Yeah... But my balls are gurgling again...”
“It’s fine. I brought three more wet dream condoms. Stick your dick out this way.”
Rhea obediently thrust her dick forward.
Lilith slipped on the wet dream condom.
“Ah...”
At the same time, a thick stream of semen trickled down.
Good thing she’d put the condom on before the ejaculation restarted.
“Nngh... How long does one episode last?”
“When you wake up, the condom’ll be pretty heavy. Check your condition then—swap for a new one or take it off entirely.”
Rhea flopped onto the bed beside Lilith.
For some reason, they were both naked.
Wearing clothes over a condom would’ve been uncomfortable anyway.
And the warm skin contact felt nice, so she didn’t complain.
“This is indigestion, not a wet dream, so you’ll probably be better by tomorrow? Assuming you sleep well and eat right.”
“Mm... Then I’ll sleep now.”
“Yeah, yeah. You did great today. Master’ll pat you to sleep, so let’s snooze.”
“You’re treating me like a baby...”
Whether Rhea was embarrassed or not.
Lilith gently stroked her belly with soft hands.
Hummm— hummm—
Each brush of her palm made the womb tattoo glow, draining tension from Rhea’s body.
Was it magic from master to kin?
Or just the good feeling making her drowsy?
Cradled in Lilith’s arms, her eyelids drooped slowly.
Swish, swish.
In the darkness, she spotted a jet-black tail swaying and suddenly wondered.
“Master.”
“Hm?”
“I’m a succubus, but why don’t I have a tail?”
It was weird, thinking about it.
All she had as succubus traits was the womb tattoo.
And rapid recovery to virgin-like state after sex.
Even Lilith only had a tail—no horns or wings in sight.
“You haven’t absorbed enough essence yet.”
“It grows once I absorb a lot?”
“Yup? I hide my horns and wings since they’re not that useful, but tails are super versatile, right?”
“Mm...”
Who knew it was DLC content.
Tails looked convenient, at least.
Like a third hand.
“You’ll grow horns and a tail too once you do more experience services. Just wait a bit, okay?”
“Yeees...”
The pleasant warmth against her whole body.
The kind hand patting her belly.
The occasional trickle of semen filling the condom.
Welcoming a night unimaginable before becoming a futanari succubus.
“Zzz...”
She drifted off in her master’s embrace.
The next morning.
Rhea woke slowly to the heavy sensation in her crotch.
No magical growth overnight.
“...Gasp!”
The condom at her dick’s tip dangled full of semen, swinging gently.
‘This much leaked all night...?’
Just from scarfing down customer semen too fast.
On the bright side, if indigestion only meant ejaculating overnight, it beat the stomach pain.
Sensing her startled rise.
“Mm... Up early, Rhea?”
“Woke up first... Hehe.”
Lilith rubbed her sleepy eyes, tying her hair up as she sat.
She should’ve looked messy fresh from bed.
But true to succubus queen lineage, even her drowsy gaze oozed sex appeal.
“Heh... Lots of semen overnight. Stay still a sec?”
Lilith rubbed from the base, peeling off the condom.
Already morning wood, so it came off easy.
Slurp.
She brought it straight to her mouth, gulping down Rhea’s night’s worth of semen.
“Mm, seems mostly better. No more gurgling like yesterday?”
She kneaded Rhea’s balls, checking.
“Not too bad.”
“Good. Then let’s exchange milk with your master.”
“...Pardon?”
Why was the morning convo going there?
She couldn’t ask.
“Remember what I said yesterday? Sleep well and eat right to recover fast. First semen of the day is extra potent, especially thick—don’t waste it.”
Rhea had morning wood; no way Lilith didn’t.
She climbed on top naturally, settling into a 69.
Shoving her rock-hard dick toward Rhea’s mouth.
Nom—
Rhea took it obediently.
Lips rubbing forced it in sometimes, but hunger helped her suck eagerly.
“I’ll suck ours too~”
Slurp— schluuurp—
Less than ten minutes after waking, the succubi devoured each other’s dicks.
Like it was the most normal morning routine, in 69 position.
Knock knock knock!
—Anyone there? It’s urgent—nobody home?
Someone pounded on the first-floor door.
“Pfah... Master, sounds like a customer.”
“Hng... Not even opening time yet. Who could it be?”
Lilith, customer-crazy, sounded unusually meh.
“Shop’s not open, and we’re eating. Can’t leave ‘em waiting outside forever, though... I’ll speed up.”
“Huh? Hngh...!”
Schluuurp—! Sluuurp—
With the early customer’s voice as BGM, Rhea’s morning turned into intense vacuum sucking.
—Anyone there~!
