Chika’s upper body was absorbed into the chest of a monster called a Steam Mimic, disguised as a treasure chest.

Inside the pitch-black box, her upper body was beginning to be assaulted.

"Ahhh...! ♡ Ah, ah, ahhh...! ♡"

"My face... and my boobs... where are you going to touch next...? ♡"

"Mimi! Mimi, meee!"

Her cheek was caressed by a tentacle. Her huge breasts were kneaded and shaken. Her belly and back were also being stroked.

Both of her arms were restrained by tentacles, stretched out to the sides, leaving her unable to move.

As Chika let out sweet moans, the Steam Mimic tormented her body with excited cries.

"Ah, ahh! ♡ Ahh, ah, ahh...! ♡ Ah, hauu, mmm! ♡ Mmm, ahh, mmm! ♡"

"Ugh, I can’t see... ♡ That makes me feel it even more...! ♡ My body is more sensitive than usual...! ♡"

Because nothing was visible, she couldn’t predict where the tentacles would reach next. Unable to mentally prepare herself, Chika felt everything more intensely than she normally would when touched.

In the pitch-black interior, she let out sweet moans, her lower body flailing wildly where it emerged from the treasure chest.

"Mimi, mimimi! Miiii, mimi... Mimi, miiii!"

"Ah, ahh!? ♡ Ah, ahh! ♡ Th-that’s no good... ahh! ♡ Ah, ah, ahh! ♡ Ah, ahhh! ♡"

"Ah... my shirt just got torn... and now you’re pulling on my boobs, nooooo...!? ♡"

While firmly holding down Chika’s swaying body with the lid, the Steam Mimic manipulated tentacles from within. It forcibly tore off the buttons of her blouse and ripped off her bra, revealing her enormous breasts. Then it wrapped tentacles around her nipples and began to pull hard.

"Meeee! Mimi, mi, mimimi!"

"H-Hyaah!? ♡ Ah, aaah...! ♡ No, no, no...!? ♡ Mmm, mm, haaah!? ♡ Ah, aaah...!? ♡ Ah, iiiiii...! Hihaaah, ah, aaah!! ♡"

"Don’t bully my nipples...!? ♡ Ah, ahh!? ♡ Don’t rub them together, nooo!? ♡ Ah, ahh, ahhhh!? ♡"

It pulled her nipples as far as they could stretch, then played with them up, down, left, and right, rubbing them together. The Steam Mimic focused its attacks on Chika’s nipples.

Faced with such intense torment, she could only surrender to whatever was done to her, and eventually she was brought to orgasm.

"Ah, ahh...! ♡ Ah, hyau!? ♡ Mm, haaa... ah, ahn, aaah...! ♡ Ah, haan, aaah... ah, aaah!! ♡ Ah, ahn, aaah!! ♡"

"N-nooo...!? ♡ Did I just come!? ♡ I came from my nipples, so don’t keep playing with them! ♡ I’m going to come again! ♡ I’m going to come!! ♡"

"Mimi! Miiii, mimi! Mimi, mi, mimi!"

But the Steam Mimic didn’t stop. Without letting up, it continued tormenting her nipples—pulling, pinching, rubbing them together. With her body still aroused from the recent orgasm, Chika couldn’t withstand the relentless assault and came again.

"Ahhh, ahhh...! ♡ Ahh, haaaan ♡ Ahh, aaaahhh ♡ Ah, aaaahhh... ♡"

The stimulation of orgasm caused the lower half of her body—still sticking out of the treasure chest—to straighten from the toes, stiffen for a moment, and then... go limp and relax.

Inside the box, Chika’s face went slack and vacant as she surrendered to the tentacles weakly wrapped around her body.

"Mimi... Mimi! Mi, Mimi! Miiii, Mimimi!"

"Ah, mmm... mmm, mmm..."

"Ah, mmm...!? ♡ Wh-what...? ♡ Now my mouth...!? ♡"

Although the interior was pitch black—perhaps because she was inside its very body—the Steam Mimic seemed to have a clear understanding of Chika’s condition. It stopped the tentacles tormenting her chest... and thrust a newly prepared one into her mouth.

"Mimi... Mi, Mimimi! Miiii, Miiii, Mimi!"

"Mmm, mmm! ♡ Mmm, uuuh! ♡ Mmmph, mmm!"

"Th-these tentacles... they look like a penis ♡ Am I being forced to suck a mimic’s penis!? ♡"

The newly formed tentacles were strangely moist, and their shape was similar to a human penis. This realization greatly fueled Chika’s excitement.

"Mimi, mi! Miiii, mimi?"

"Mmm, mmm! ♡ Mmm, mmm, mmm! ♡ Mmm, mmm...! ♡ Mmm, mmm! ♡"

"A penis-like tentacle thrusts deep into my mouth...! ♡ My mouth is violated by the mimic’s penis... ahh, ahh ♡ My breasts are also being tormented... I’m being made to feel so much, so much!! ♡"

As Chika grew more excited, the fleshy tentacle began moving inside her mouth—deep into her throat, then pulling back, then plunging again. It moved freely inside her while the torment of her breasts resumed.

Chika felt increasingly overwhelmed by the assault, and then she came again, straightening her toes and trembling uncontrollably.

"Mimi! Miiii, Mimi! Mimi... Mi, Miiiiiii!"

"Mmm! ♡ Mmm, mmm, mmm! ♡ Mmmph, mmm...!! ♡"

"Ah, ah...! ♡ Th-this feeling is... ah, ah! Semen is coming...!? ♡ M-mimic’s semen is coming...! ♡"

As Chika reached her climax, the Steam Mimic seemed to grow more aroused inside her mouth. Its thrusting tentacle-like penis trembled... and ejaculated.

Because it ejaculated deep in her throat, the thick, viscous semen poured directly into her stomach. As Chika felt the hot fluid accumulate inside her body, she trembled and came again.

"Mimi, mi...! Miiiiiii... mi, mimi!"

"Mmm... ♡ Mmmph, mmmh!? ♡ Mmm, mm, mm, mm! Mmmhhh!! ♡"

"Ah, uh, uh...!? ♡ You’re going to use my breasts too...!? ♡ How much of my body is going to be used by this mimic...!? ♡"

After pouring a large amount of semen into Chika’s belly—without withdrawing the fleshy tentacle from her mouth—the Steam Mimic prepared another one. It inserted that new tentacle into the cleavage of her massive breasts, which it had been kneading, and began to give her a titjob while using the other tentacles to knead and shake them.

"Mmm, mmm! ♡ Mmm, mmm!! ♡ Mmm, mmm, mmm! ♡ Mmm, mmm, mmm!! ♡ Mmm, mmm, mmm!! ♡"

"My boobs are being used... and my mouth is being used too... to have my body used by such a mimic... it’s frustrating... ♡ But I can’t help but feel it... the more frustrated I am, the more pleasurable it becomes...!! ♡"

"Meeeeee! Mi, mimi! Mimeeeee, mimi! Meeeee!"

The fleshy tentacle inside her mouth began to move again. Chika fully felt the stimulation—the moist texture, the heat of the tentacles moving violently in her mouth and between her breasts. Although she felt frustrated, she added that frustration to the pleasure, feeling everything intensely, and came again and again.

"Mii! Miiiiiii! Miiii, Miiii, Miiiiiiiiiiiii!!"

"Mmm, mmmhh!! ♡ Mmm, mmm, mmm, mmmhh!! ♡"

"My pussy hasn’t even been used yet, but how much pleasure can I feel?! ♡ How much pleasure can a mimic give me?! ♡"

Ahhh, ahh, ahhh!! ♡

Once again, the Steam Mimic ejaculated from both fleshy tentacles—into her mouth and onto her chest. The sensation of the hot, thick semen made Chika’s body convulse as she came. Her lower body, still sticking out of the box, stiffened as she climaxed.

"Ngh, hiiii... ♡ Ngh, hiiii... ♡"

"Ahhh... I was made to feel so good by that double attack on my mouth and breasts... ♡"

Her lower body trembled uncontrollably. Sweat seeped down her thighs, and her panties were damp, but mixed in with the sweat was a different liquid—honey-like fluid dripping from between her legs, giving off the scent of a female.

"Mimi...! Mimi, Mimi! Mimiiii!"

"Mmm, mmm! ♡ Mmm, mmm!"

"Ah, ahh...! ♡ You’re still tormenting me... what’s going to happen to me...! ♡"

Even after all of this, the Steam Mimic was still not satisfied. It continued moving its penis-like tentacles, tormenting Chika’s mouth and breasts. Faced with that torment, she let herself be used, let herself feel good, let herself experience everything intensely—reaching orgasm after orgasm.

How many times was she violated?

"Mmm...! Mimi...! Mimiiii... Mimi..."

After what was probably the umpteenth ejaculation, the Steam Mimic spat Chika’s body out of the box. Leaving her behind, the chest bounced up and down and hopped out of the room.

"Ah, hyah... ♡ Hya, ah, ahya, aaah... ♡"

"Ah, ahh... I can’t believe I was defeated by a mimic... not by a mimic... ♡"

My pussy hasn’t even been used... ♡

I was made to feel so good that I ended up like this... ♡ Ah, ah... ah, ah, aaaah... ♡

And what of Chika, left behind?

Her face and chest covered in semen. Completely melted, flushed, with a dazed expression. Staring blankly at the ceiling. Her body twitching and jumping, honey-like fluid still squirting from between her legs.
