"Mmm... mmm, ahh..."

"Mmm, mmm♡ Mmm, mmmh..."

"...♡"

"Oh my...♡ We have already started kissing...♡"

The erotic encounter between the head of the household, Sekuki, and his maid, Marie, began in the library. Whether they noticed Chika hiding behind the bookshelf or not, the two were engrossed in passionately exchanging kisses.

"Mmm... mmm, mmm, mmm... haaa, mmmmm..."

"Mmm, mmm haa♡ Mmm, mmm♡ Mmm, haa... mmm, mmm, mmm haa♡"

While pressing Marie’s hands, which he had grasped, against the bookshelf, Sekuki thrust his tongue into Marie’s lips and mouth, licking and ravaging her as if to devour her. It might have appeared one-sided, but Marie also reciprocated by intertwining her tongue with his, and it seemed they were both thoroughly enjoying each other.

"Mmm, haaa... haaa, kufufu."

"Mmm, ahh♡ Ah, mmm, haaa♡"

After enjoying each other’s lips for a full minute, Sekuki and Marie separated, their mouths still connected by a bridge of saliva, and gazed at each other with passionate eyes.

"Haaah... kufufu, Marie. Show me your breasts."

"Ah...♡ Mm, yes♡ Please, husband♡"

After gazing into each other’s eyes, Sekuki released Marie’s hands and spoke. Marie nodded with a melting smile, then began unbuttoning her maid outfit and quickly shifted her bra aside to expose her breasts.

"Hehehe... as naughty as ever. Well then... let me have some. Mmm, haaa... mmmhhh."

"Hehe, my husband is giving my breasts a good, naughty time... Please enjoy them to your heart’s content♡"

Marie’s breasts were revealed, bouncing and jiggling. Though not as large as Chika’s, they were still enormous—at least a G-cup. Sekuki licked his lips at the sight, took her right nipple into his mouth, and began to suck on it, then reached out and started kneading her left breast as well.

"Ah, ah♡ Ah, ahn, mm, haaan♡ My husband’s tongue is licking, licking...! ♡ Hiu, mm, ah, aah, ah, aah! ♡"

"Mmm, haaa... haaa, mmmmm... mmm, hehe, Marie, it is tasty. Your breasts are tasty... hehe, hehe... mmm, haaa..."

As Sekuki sucked on her nipples, Marie let out sweet moans. Seeing her wriggle her hips in pleasure, Sekuki laughed lewdly and continued to suck and lick her breasts.

"..."

"Wow...♡ Seeing her breasts being sucked like that gives me chills...♡"

Chika watched the scene unfold from behind the bookshelf. Perhaps influenced by the excitement emanating from the two, she was also becoming a little aroused, and she tightly hugged the mop she was holding, pressing it between her chest.

"Hmm? ♡ Oh? Is that perhaps..."

As her excitement grew, Chika noticed something.

"Ah, ah! ♡ My milk ♡ My milk for my husband ♡ Ah, ahh, ahh, ahh! ♡"

"Hehehe... It is delicious, Marie. Your milk is... hehe, hehehe... mmm, haaa..."

"Oh, that girl... she is lactating...!? ♡"

Milk was flowing from Marie’s breasts. From the left nipple, which was being massaged, a small spurt of fluid occasionally shot out. Milk also seemed to be coming from the right nipple, and Sekuki, who was sucking on it, appeared to be savoring and drinking it.

"If she is producing breast milk, does that mean she has given birth before...? ♡ Or perhaps she was given some kind of drug to induce lactation? Ugh... I am so curious... ♡"

"Ah, ah♡ Ah, ah, ahh♡ My husband♡ My husband♡ Ah, ah, ah, ah, haaan♡"

"Mmm, haaa, haaaa... Mmm, haaaa..."

Seeing Sekuki and Marie engaged in what appeared to be a breastfeeding play session, Chika became even more excited and began stroking her own breasts around the nipples.

While Chika was getting excited on her own, Sekuki finished tasting the breast milk and slowly removed his mouth from Marie’s nipple.

"Mmm, ahh... Ah, Marie’s milk was delicious. Hehehe."

"Ahhh, mmm...♡"

"Wow... there is saliva and breast milk on your breasts... so naughty♡"

When Sekuki released Marie, her breasts were covered in saliva and milk, creating an undeniably erotic sight. As Chika grew excited by the sight, Marie quietly reached her hand down to Sekuki’s crotch.

"My dear husband♡ Please let me be your partner next♡ I will take care of you here♡"

"Hehehe... I see, I see. In that case, I will use this next. Hehehe."

Marie stroked his crotch through his pants and spoke in a sweet, seductive voice. Sekuki agreed with a lewd smile and a nod, then quickly removed his pants, revealing his penis.

"Wow...♡ It is so big...♡"

"Ahhh... my husband’s penis... ♡"

Sekuki’s exposed penis was already erect, displaying an impressive size. Seeing this, Chika and Marie both grew excited, and Sekuki called out to them with a grin.

"Hehehe... Now, Marie. Put your hands on the bookshelf and stick your bottom out."

"Oh, yes...♡ I understand♡"

Upon hearing those words, with breast milk still seeping from her chest, Marie turned her back to Sekuki, placed her hands on the bookshelf, and adjusted her hips so that Sekuki could easily insert himself.

"Come on, whenever you like♡ Put my husband’s cock into my pussy... uh! ♡ Ah, haaaah!! ♡"

"Ah, I will put it in, Marie... Kufufu, fuh... Hmm..."

Seeing the position Marie had taken, Sekuki groaned with satisfaction, then reached for her skirt and lifted it, removing her black tights and panties to reveal her already soaking wet pussy. Without waiting for Marie to say anything, he inserted his penis.

"Ahhh! ♡ Ah, aaaah, haaaah!! ♡ My, my husband’s dick...! ♡ Your dick, into my pussy... aaah, ah, hiaaah! ♡"

"Hehehe... Now, let us get moving, Marie... Haa, haaa! Haaa, haaa!"

As the cock was inserted, Marie arched her back, her bare breasts jiggling, and she came, squirting breast milk as she climaxed. Looking down at her, Sekuki let out an excited cry, grabbed her waist, and began thrusting violently.

"Ah, ahn! ♡ Haaah, aah! ♡ Aah, aaah, ah, haaaah!! ♡ Mmm, mmm, mmm, mmm, haaaah! ♡ Aaah, h, aaaah!! ♡"

"Hmph...! Hmph, hmph! Hmph!"

Each time Sekuki’s hips slammed against hers, Marie’s sweet voice rang out.

"...Ah, mm...♡ Mmm, ah...♡"

"What should I do... Looking at this is making me feel hot...♡"

Chika’s face turned bright red, and she fidgeted. She began rubbing her crotch—her pussy—over her black tights and panties with the mop she was holding.

"Ah... mm, ah... ♡ Ah, ah... ahhh... ♡"

"Watching sex like this makes me so excited...♡ My pussy is throbbing...♡"

Up until now, most of the erotic events Chika had experienced involved her being the one violated, so she had never had the chance to calmly watch other people having sex like this. Perhaps that was why she continued to rub her pussy with the mop, feeling an indescribable, gradual excitement.

"Ahhh, ah, ahn!! ♡ Mmm, haaaan!! ♡ Aaah, ah... hihaaan!!? ♡ Hyaah, hah... mmm, ah, aaaan!! ♡"

"Hmm, hmm! Mmm... hmmm!"

As Chika grew more aroused, Sekuki swayed his hips and reached for Marie’s bouncing breasts, beginning to pinch and play with her nipples. When he pinched and teased her nipples, milk naturally spurted out. Breast milk splashed onto the books on the shelves, but Sekuki did not seem to mind at all and continued to knead Marie’s breasts while thrusting his hips. Marie became incredibly turned on by the stimulation.

"Hehehe! I am going to let it out! Here we go, Marie!"

"Ah, ahh! ♡ Yes, yes, husband! ♡ Please pour lots of your semen into my pussy! ♡ Ah, ahh, ahhhh!! ♡"

Sekuki ejaculated inside Marie’s pussy, pouring his semen into her vagina. Marie came from the force of the semen being poured into her, and her breasts squirted milk everywhere.

"Ah... ah, ah... ♡ Mmm, ah, aaah...!! ♡ Mmm, haa, ah..."

"Ah, ahh...♡ I... I just came...♡"

While watching the internal ejaculation, Chika also came, albeit a small one, from the stimulation of rubbing her vagina with the mop.

"Hehehe... Come on, we are still going, Marie... Make sure you keep up with me...!"

"Ahhh...♡ Yes, yes...♡ More! ♡ Do it more, my dear husband...♡"

Without noticing Chika, the sex continued even after ejaculation. Marie willingly allowed herself to be violated.

"Hehehe... That was good, Marie."

"Thank you so much...♡ My dear husband♡"

Afterward, when Sekuki had ejaculated about five times, the two finished having sex and began to straighten their clothes. Marie wiped the breast milk and spilled semen from the bookshelf and cleaned up the mess. Then the two left the library.

"...Ahhh♡ Ahhh...♡"

Hearing the door slam shut, Chika dropped the mop she had been using to rub her vagina and collapsed to the ground.

"Ahhh...♡ It was nice to calmly watch other people having sex. It felt different from usual...♡"

Still lingering in the afterglow of her orgasm, Chika spoke with a melted expression, reminiscing about the sex she had just witnessed. After reflecting for a moment, she suddenly began to worry about Marie.

"But still, looking at Marie’s reaction... if I were violated here, would I end up like that? Would I be trained until I succumbed to pleasure...? ♡"

If that were true—if her true identity were revealed, if she were caught and could not escape—she was sure she would end up being trained just the same.

"Ah, haa...♡ Yes, that... might be good...♡"

Seeing Marie’s appearance, which hinted at what this quest entailed—a vision of her own possible future on a bad route—Chika felt a shiver run down her spine. At the same time, her pussy grew wet, and she became aroused.
