My Taboo Academy

I sent back a photo of myself lying down, shirtless, for no real reason.

[Ren Asahi]

*(Shirtless selfie)*

Looking at it objectively, if I were a woman that face and body would probably stir something.

[Ren Asahi]

Good night

[Regina Dean]

.

Just a single period.

The house went quiet.

Last night Yuna had come to my room... and it had felt good.

Was I actually disappointed that I didn’t have a little sister handling me tonight?

’I’m losing it.’

What kind of thoughts was I having about my own innocent sister who was still figuring out her curiosity about sex?

Sneaking into her brother’s room every night wasn’t normal.

If I could just keep things from going too far, we might actually become a proper family.

’My libido is completely broken.’

After everything I did during the day it should have been spent. Instead it felt stronger than ever, like sex had woken something up.

’Yuna...’

I couldn’t sleep. The image of her from behind kept looping in my head.

Hours of tossing and turning. I was going crazy.

Sleep refused to come.

From a pure game-logic standpoint, shouldn’t I have taken the opening when she was teasing me in the kitchen?

Wouldn’t she have answered happily, hips swaying?

Dirty thoughts kept spinning.

’Perverted Ren to the rescue.’

Would Yuna accept it if I went to her?

My cock stayed hard, refusing to calm down. I wanted relief from her specifically.

Acting on pure instinct, I found myself standing outside her door, fully erect.

"..."

The door was slightly open. I could see her inside.

’What’s she doing this late?’

Yuna sat on her bed, carefully mending my school uniform.

At this hour...

I hated myself for almost walking in with a hard-on, unable to control the urge.

How was I any different from the original owner of this body?

’I’m sorry, Yuna.’

I promised myself I’d get a grip.

Tonight I’d just take care of it alone and sleep.

*Ding.*

[Elle]

*(Photo of her chest after a shower, towel barely containing everything)*

Perfect timing, as if sending tempting pictures was part of her best-friend duties.

[Ren Asahi]

I told you not to send pictures like this

Even while typing that, I was already stroking myself to the image. Elle would never know.

A little guilt, but this was just how men worked.

She was the one who took and sent a photo that provocative.

[Elle]

Face

[Ren Asahi]

Face?

[Elle]

I framed it so my face wouldn’t show

With breasts that size, anyone who knew her would recognize her instantly if the photo leaked.

[Ren Asahi]

One more

At this point I’d already lost the argument with myself.

[Elle]

*(Photo of her making a V-sign with an awkward smile)*

In the second shot the towel had slipped just enough that the edge of one nipple was almost visible.

[Elle]

Oops

She must have noticed a second too late.

[Elle]

I’m embarrassed

[Ren Asahi]

I’ll only look at it myself

Thanks to Elle I managed two intense rounds and finally passed out.

---

Third morning since waking up in Lustbound.

"Chup... chzzup..."

The shockingly pleasant way I woke up was entirely Yuna’s fault. I lifted the blanket and found her curled up like a cat, both hands wrapped around my cock, mouth full.

"...Chup?"

"Yuna... what are you doing?"

"Paha..."

She pulled off with a wet sound. My cock was already shining with her saliva. She’d clearly been licking and sucking while I slept.

"It’s a my job to take care of your morning wood."

"There’s no rule that says that."

"Sorry about last night. I left you all lonely..."

No way.

Had she seen the tissues from earlier?

That was mortifying on its own.

"Isn’t a my mouth better than tissue?"

She took me back into her mouth in one smooth motion.

"Gulp... mm... nn... paha... You can cum as much as you want. I can do things a girlfriend never would."

Where the hell had she learned this twisted idea of sisterly duty?

On the first day I would have stopped her immediately.

But now...

[Morning Bonus Quest ]

[Simply enjoy Yuna’s oral service ]

My resistance was already weaker than it had been on day one.

There were too many reasons for this morning’s weakness.

Yuna’s soft beauty, Elle’s impossible chest, Aria’s thighs and that quiet smile, the Student Council President’s hips... and above all, the memory of Regina Dean still clinging to my memory.

When she leaned in with that hopeful, hungry expression, my thighs simply opened.

"Chuurup..."

With my silent permission, Yuna sank down and took me into her mouth. Her lips sealed tightly, cheeks hollowing as she tried her hardest to please. The moment she realized I was watching, a shy flush colored her face, but she didn’t stop. If anything, she worked harder.

*Slurp... slurp... slurp...*

Her tongue never stayed still. She licked along the underside, flicked against the sensitive spot just under the head, then glanced up at me through her lashes. I rested a hand on her black hair and stroked gently.

"Mmmh..."

The skill flooded her with pleasure the second my fingers touched her scalp. In practice it was little different from a drug warm, melting euphoria that made her melt around me. Treating my own sister like a Fleshlight should have felt wrong. Instead it only made the heat sharper.

*Slurp... suck... nibble...*

Yuna swayed her hips lightly while she suckled, eyes half-lidded and soft under my hand.

"Does it taste good?"

*Chirp... gulp...*

Her purple eyes narrowed in pleasure. Whenever our gazes met she grew even more focused, swirling her tongue around the head still trapped between her lips. The more I praised her and stroked her hair, the more devoted her service became.

"Delicious... your thick, handsome cock... I love it more than breakfast..."

She even dropped lower and licked my balls, nuzzling the entire length with her pretty face.

’Fuck...’

"Hah..."

All that enthusiasm for her first real blowjob was already tiring her jaw. When I kept petting her she made a small, spoiled sound and started pressing soft kisses along the shaft instead.

"It’s so big... my mouth is getting tired."

"Go slow. No rush."

"Kiss... kiss..."

She kept kissing the tip.

"I’m the first one who ever kissed your cock, right?"

"Where did you even learn to say things like that?"

"Slurp... slurp..."

Feigning pure innocence, she licked from side to side across the head.

"Please... put it all the way in my mouth..."

"Open."

"Aah..."

I rested the head on her tongue and pushed forward until I was buried deep in her throat.

"Gawkk"

Yuna’s lips stretched tight around the base. The way her tongue fluttered right under the head nearly undid me on the spot.

’If I’d known her mouth felt this good...’

I would have given in much earlier. The filthy thought made me press down on her head a little harder.
