Chapter 13: Breast Development

"Alright~ Turn over and lie on your back~"

"Let's take another look at that dick~?"

"..."

Sylvia moved down from my lower back and sat demurely beside me. Despite my reddening face, I rolled over to lie properly on my back.

There's no point resisting in this state anyway. I'll just focus on holding back the pleasure.

Squeak-

As I lay face up, I felt the smooth sensation of the air mattress against my back. And standing proudly in the air, asserting its presence... was my erect penis.

Seril and Hilda leaned their faces toward my dick with devilish smiles. Then, they spoke to it from close enough that I could feel their breath.

"Hehe. Little dick will have to endure, won't you~?"

"If you cum without permission, you'll get a spanking~"

Twitch-

Instead of answering, I flexed my lower body slightly, making my dick move. Even without them saying so, I planned to hold back ejaculation as much as possible.

I may not have any pride left, but that's the best I can do.

"Oh my, good boy~"

"That was a proper response~"

They playfully poked at my twitching dick with their fingers. Meanwhile, Sylvia gazed intently at my penis for a moment before shaking her head and leaning toward me.

She lay down on my right side as I lay straight. Like lovers sharing a bed. Lying on her side, Sylvia pressed herself against me.

Squish-

"!"

The sensation of breasts against my right arm. I froze in place, staring silently at the ceiling. I couldn't dare look at Sylvia lying beside me, afraid she'd see how red my face was. I couldn't meet her eyes.

'Form is emptiness, emptiness is form...'

As I recited a Buddhist sutra I didn't understand, trying to endure, Sylvia whispered carefully in my ear.

"Don't be tense. Just leave everything to me like before."

Slick-

Sylvia lightly licked my earlobe. A tingling sensation shot from my ear up my neck to my head. After checking my reaction, Sylvia called to Seril who was examining my penis.

"Seril. Come lie on the opposite side."

"Okay~"

"Hilda, massage the perineum from there. Don't touch the anus."

"Got it~"

Following Sylvia's orders, Seril came and lay on my left side, while Hilda remained by my lower body preparing something.

"Hehe~ Your ear is so cute."

Seril, lying on my left, smiled with crescent eyes before gently biting my earlobe.

"Hng."

As I twisted slightly, Sylvia on my right calmly whispered in my ear.

"When I made you ejaculate in the forest earlier, you seemed to enjoy being whispered to. It appears to have meaningful effects for sensual development, so this time we'll whisper from both sides. Seril, if you please."

"Yes~ I'll whisper lots of naughty things to you."

"Very good. Then."

Rustle-

Sylvia unwrapped the white towel covering her breasts and body.

"!"

I unconsciously turned my head to look at Sylvia's naked form but...

Plop-

Before I could take in those alluring breasts, Sylvia placed the towel she'd removed over my face. Tch. While I was slightly disappointed not to see Sylvia's nude body, I decided to make do with the warmth and scent of the towel that had been wrapped around her.

"When the eyes are covered, other senses become more sensitive. Keep the towel over your eyes properly."

Swish- Swish-

The towel that had been carelessly draped over my face moved as if by magic, wrapping warmly around my eyes. The pleasant weight and warmth covering my eyes put me at ease.

"Kufufu~ Can we start then, Head Maid?"

"Yes. Start from the outside first."

With my eyes covered, I could only hear their voices, having no idea how they were moving.

Because I couldn't tell what stimulation would come next, my whole body felt sensitively heated with a strange mix of anticipation and fear. Just as I swallowed hard, expecting what was to come...

Brush-

The first touch came to my right chest. Though I couldn't tell exactly, it felt like Sylvia's hand gently caressing where my ribs met my chest.

At the same time, slender fingers settled on my left chest and began tracing across it.

"Ngh."

Since Sylvia had already caressed my chest with oiled hands earlier, the area was sensitive, and when they touched it again, a strange pleasure gradually rose.

But it wasn't quite enough to call pleasure. Somehow it felt lacking...

Squeeze-

Sylvia soon gathered her hands and pushed my chest together as if milking a cow. But since my chest was flat unlike a cow's, not much flesh gathered.

As I was questioning this action, Sylvia whispered to me in a calm voice.

"What we're doing now is preliminary work to develop your nipples. We start by stimulating the mammary glands around the chest to gradually awaken sensation."

"Chest... mammary glands?"

Aren't those only in women who breastfeed? I'm a man. Then Seril's voice came from my left ear.

"That's right~ Men have mammary glands too, though they're atrophied. If we massage them well like this, they'll develop bit by bit."

Knead-

Seril also massaged around my chest and the area connecting to my armpits like Sylvia. While I didn't feel much pleasure, there was a strange sensation and my chest gradually felt warmer.

Sylvia continued kneading my chest as she whispered in my ear.

"Normally this would need to be developed very gradually over a long time... but you have talent."

"I'm not really happy about that..."

While being told you have talent would usually be taken as praise, I felt uneasy. What good could come from having talent for nipple development?

"No. You should be happy. This kind of talent isn't something everyone has."

Sylvia and Seril, who had been pushing my chest outward with their palms, soon changed their hand movements.

This time they raised one finger each and began circling around my areolas.

"Hii!"

Unlike before, this time a slight pleasure tickled my chest. When I let out a small moan, Seril grinned beside me.

"Heh? Does it feel good when we tickle your chest~? Just like a woman~"

"I'm not like a woman..."

"Indeed you are. The pleasure in your chest is a woman's pleasure. You truly have overflowing potential."

"N-no, that's not..."

Rub- Rub-

Sylvia kept whispering in my ear in a pleasing low voice while rubbing circles around my areola. When Sylvia joined in too, it started feeling strange. Calling me womanlike...

I shook my head slightly to deny it, but honestly, there was a subtle pleasure when they rubbed around my areolas.

'Why... Could it be because of the oil?'

I wondered if this slick, warm liquid might contain some aphrodisiac. Otherwise how could my chest feel good? I'm a man after all.

"Denial is pointless. You'll end up admitting it yourself eventually."

The two slender fingers that had been tracing clockwise around my areolas gradually made smaller concentric circles as they approached the areola itself.

Rub- Rub-

It was such a subtle movement I normally wouldn't have noticed, but with my eyes covered and focusing on my chest, the movement felt as clear as if I could see it.

"Now then~ We're getting closer? Female nipple-chan~"

"Please breathe slowly and deeply, and concentrate."

"Haa... haa..."

As I took shallow breaths, feeling the two fingers approaching my chest, I also felt a sensation from below.

Something heavy and soft touched the skin between my anus and testicles, my perineum.

'....No way!'

They're not going to put something in my ass are they? As I tried to raise my body with an uneasy sensation, Hilda's reassuring voice came from below.

"This is my tail~ Don't worry, I won't insert it~"

Thrumm-

"Just enjoy the vibrations you feel~"

At the same time, a strange vibration from the object touching my perineum. It was such a subtle vibration that I could barely tell if it was there or not.

A demon girl's tail touching around my ass. Somehow it was both scary and arousing.

"Focus here too~ Take this!"

That's when it happened.

Seril, who had been circling my areola with her finger, raised her nail and flicked my nipple.

"Hyah!"

The sudden jolt of pleasure in my nipple made me let out a feminine moan. Then Sylvia also lifted her fingers from circling my areola and gently pinched my nipple between her thumb and forefinger.

Then she slowly twisted the pinched nipple while applying pressure.

"Hiyah!"

I bounced slightly, my hips jumping at the sensation from both nipples. Such sudden pleasure?

"Haa, haa."

I panted at the hot sensation gradually rising to my head. Then Sylvia's voice came to my ear.

"Sensitivity confirmed. You seem sufficiently aroused now. Then."

Rustle-

"Let's begin layering the pleasure."
