The sex room in this mansion is the same place where Nanako was once turned into a lewd slave. Just as she once used it as a bedroom, it is a well-soundproofed Japanese-style room where outside noise cannot penetrate.
Though it is a six-tatami room—relatively small for such a lavish mansion—it doesn't feel particularly cramped since it only contains a writing desk and a clothing rack besides the three futons already laid out with the heater running. After surveying the room, I announced my next move.
"Alright, I'll go clean myself up first."
"Understood. Allow me to guide you."
"Take your time, Master."
"Please relax."
Bidding farewell to Isla and Charlotte, who bowed deeply, I left the room with Nanako. Since I already knew the way to the bath, I walked ahead with her trailing behind.
Upon arrival, Nanako handed me the already prepared items before leaving the changing area. Once she was gone, I opened the door to the bath.

"——How much longer? How much longer?"
Having finished washing, I waited impatiently for the three of them in the aforementioned room. True to the mansion's grandeur, its bath was extravagant, and I had ordered them to cleanse themselves together.
Dressed in a white, period-drama-style sleep robe, I sat on the futon and killed time by fiddling with my phone. Just as the wait was becoming unbearable, a voice finally called from the hallway.
"Master."
"...Yeah, come in."
"Then, pardon our intrusion."
Placing my phone on the writing desk, I responded as the sliding door opened sideways. They entered solemnly in order: Nanako, Isla, and Charlotte.
All three wore white sleep robes similar to mine, reminiscent of historical dramas. The lewd slaves knelt before me in seiza, placing three fingers on the floor in deference.
"We apologize for making you wait."
"Tonight, the three of us will serve you."
"Please enjoy yourself to your heart's content."
After speaking, the three exchanged glances, nodded, and rose to their feet. Then, they each reached for their robes and began slowly undressing.
As the white silk slid off their bodies, three distinct nude figures entered my view—an exhibition of breasts of entirely different sizes: 77cm B-cups, 86cm D-cups, and 99cm H-cups.
Running my fingers over their lower abdomens one by one, I channelled mana, causing their lewd crests to glow. While Charlotte's mark had matured to the same stage as Isla's, Nanako's was still in the process of growing.
With their marks shimmering, the three naked women closed in on me all at once. Gently and meticulously, they removed my sleep robe and guided me onto the center futon, laying me on my back.
"Now then, Master…"
"Leave everything to us."
"Please feel good…"
The moment those words were spoken, they all attacked simultaneously. Below my waist, Nanako took my cock into her mouth without hesitation, while Charlotte sucked on one of my nipples and teased the other with her fingers.
Isla pressed her lips to mine, slipping her soft tongue into my mouth. The triple assault of their lewd service instantly set my lust ablaze.
"Mmm, slurp… Master's is so big… and delicious…"
"Nnch, lick… Do your nipples feel good? Master..."
"Chu, chu… gulp… Master's saliva is tasty…"
"Ahh… This is amazing…"
Being served like this made me feel like the king of a harem. Well, it's not wrong—I am the master of a harem.
That said, the fervent attention from all three at once was too intense for me, especially after holding back for a whole week. For a high school freshman boy at the peak of his urges, this was unbearable teasing.
"Slurp… Ugh, this… this is bad. If this keeps going…"
"Chu… Would you prefer to… put it inside my pussy instead?"
"Lick… Master, aren't you… finishing faster than usual?"
"Nanako's mouth… feels that good, huh…?"
"...Honestly, yeah... Guess her dead husband trained her well."
"Please don't talk about him... Right now, I belong only to you, Master."
Even as she spoke, Nanako stopped her blowjob and straddled my hips. Gripping my fully erect cock, she guided it to her entrance with practiced ease and began lowering her hips.
"Nngh… Master's is… going inside…♪"
"Ooh… That's it…"
The inside of the widow welcomes my thing with complex movements. Moreover, having fallen into being a lewd crest slave, her tightness has become exceptionally good, and now she's arguably the best among the sex slaves in terms of feel.
"Ahh~! Master~! Master~!"
"Guh... Still amazing as ever..."
While swaying her soft, voluptuous breasts leisurely, Nanako continues her cowgirl service. Isla moves over to share my nipple with Charlotte.
As Isla and Charlotte tease my nipples, I savor the softness of their breasts in my palms. The pleasure surging through my entire body makes it impossible to stop the pre-cum from oozing out of the tip buried inside her pussy.
"M-Master~? Ahhn~ P-Please, be kind to me soon..."
Suck...
"D-Does it feel good...? Master~"
"P-Please... squeeze my breasts more..."
Nanako's vaginal mucosa writhes with countless tiny folds, each one squirming to drag me deeper inside. With my entire shaft enveloped by those lewd walls and pistoning in and out with wet, obscene sounds, it's unbearable.
Meanwhile, Isla and Charlotte take turns licking my areolas, sucking hard on my nipples before nibbling them sweetly. Under this coordinated, sweet torment from the three of them—and after holding back for longer than usual—I'm quickly driven to the edge.
"I-I can't... I'm gonna cum soon...!"
"Y-Yes~ Mmmph~ P-Please, don't hold back..."
At my words, Nanako's pace quickens even more. Watching her ride me while kneading her own 99cm breasts, the moment of release finally arrives.
"Ah! I—I can't hold it! I'm cumming!"
"Master~! Please, give me your seed! Give it to meee!"
"N-Nanako?! I-I'm cumming?!"
"P-Please... give me lots...!"
"Ahhh!! I'm—I'm cumming!! Uwooooh!!! …Nngh!"
"Ahhh! Master's—!! Master's hot load is!!! ♡ Aaaahhh!!! ♡"
While Isla and Charlotte suck on my nipples, I arch my hips and erupt inside Nanako like a fountain. The shock makes her lewd mark glow intensely as she follows right after me.
Even the long, drawn-out ejaculation, sweetly milked by Nanako's clinging walls, eventually ends. As I knead Isla and Charlotte's breasts, I bask in the lingering pleasure of my release.
Nanako, too, drowns in her afterglow, her engraved lewd crest flashing wildly. With her spine arched, shoving her massive breasts forward as she stiffens, she looks incredibly erotic.
"...It's about time to switch, don't you think, Nanako?"
"Senior... It's my turn next, right?"
"Yes. That was the agreement, wasn't it?"
"... Hah... Fuu~ S-Sorry... I'll move now..."
When the other two speak up, Nanako lifts her hips, freeing the cock glistening with her juices. Then, Charlotte immediately latches onto it, still hard despite everything.
"Master~ It's my turn now, okay? First, I'll clean you up~"
"O-Ohh..."
"Mmm… Lick, lick… So amazing~ Even after cumming, it's still this hard..."
Charlotte begins licking my overly sensitive cock with her tongue, lapping up the sticky fluids before taking it into her mouth, transitioning into a full-on cleaning blowjob.
"Well then... Gluck... Mmmph..."
