At Your Service M'ladies

A week after..

NOTE: THIS IS A BIT OF A REVAMP

The days have been peaceful, you were able to get back to walking and still have your ability to.
You've been occupying yourself with cleaning the estate and tending to your masters.
It's a bit repetitive until one morning Shinobu taps your shoulder.
"_? Can I ask you something?"
You straighten up.
"Yes M'lady! I shall do whatever you ask!"
She gives you a slight smirk and hands you something wrapped up.
"Don't open it, it has a note along with money in there, any herb vendor should have it, just give it to them. I want you to bring back the plant they give you, I need it for- an experiment."
You nod.
"As you wish M'lady!"
You speed out of the door, closely carrying the package.
You finally arrive at a herb vendor and give them the package.
They open it, then start chuckling.
"So you want this? Ha, lucky for you, I have some strong ones."
After a few minutes they hand you a kilogram of the herb.
You smile at being able to accomplish your lady's task, but it did take you an hour to get there so it'll be awhile.
"Thanks for the herbs!"
You walk away and wave.
They still look like they're going to bust out laughing.
You ignore it and speed back to the estate.

Back at the estate

You open the door and don't see Mitsuri or Shinobu.
Setting down the herbs, you begin looking around but your search is instantly complete.
You hear muffled moans.
You blush at the thought of it.
After heading to the bedroom, you find the door is wide open.
....It wouldn't hurt to take a peek, would it?
You swallow, the chance to get to see them, it's almost orgasmic!
You slowly crouch to the floor and peek through the door, your face instantly turning red.
Shinobu is sitting on Mitsuri's chest.
You can hear Mitsuri making soft moans and gagging sounds from having Shinobu's cock shoved into her throat.
Shinobu is smirking at her.
"You like that don't you?.. What if I?~"
Shinobu thrusts forward slightly, making Mitsuri whimper a bit.
Shinobu chuckles softly, pulling out.
"How about a change of scenery?~"
She goes down Mitsuri's body as Mitsuri herself pants.
You move away from the door a moment, your nose is bleeding a bit and you wipe it.
At the moment, you're just trying not to make any noise, as well as not making yourself known.
"I can't believe I got to witness something this-"
Before you can finish your thought, you hear a loud moan from Mitsuri.
You instantly peek into the door again.
Shinobu has Mitsuri pinned down while slowly stuffing her cock into her.
Mitsuri is making very audible whimpers.
Shinobu chuckles. 
"You want more?~ Beg for it~"
"P-please Shinobu..~ I want more- Ngh!~"
Shinobu swiftly stuffs her entire cock into Mitsuri.
"T-too much!~"
Shinobu grins.
"Didn't you beg me for this?~"
She pushes her fingers onto Mitsuri's swollen clit.
"P-please!~"
Shinobu doesn't seem to care, going as far as stuffing her fingers in making Mitsuri loudly moan.
You quickly turn away from your embarrassment of watching this, but at the same time you can't help but want to be one of the two...
As the thoughts pollute your mind you shake your head.
"Don't get yourself all riled up just yet..."
You take a deep breath before peeking in the room, only to get a sight of Shinobu completely stuffing her cock into Mitsuri whilst gagging her.
The sounds Mitsuri were making are silenced, the loudest sound being a low whimper.
The slapping of skin is the loudest sound now as Shinobu thrusts herself in and out of Mitsuri.
Shinobu just seems to be all smiles, humming as if she's doing a simple task with every thrust, you can hear her breath hitch for a moment, making her stop for a moment before continuing, going faster than before.
You hear Mitsuri's muffled whimpers as she squirms and trembles under Shinobu.
Shinobu just goes faster and rougher, all the way until she finishes, going to pull out slightly but getting pulled back in by Mitsuri.
Shinobu bites back a yelp or whimper from getting stuffed back in while being in the middle of her orgasm.
You slink back into the hall, just waiting for them to finish completely.

After about an hour of listening to sounds of pleasure and the slapping of skin, the Insect Pillar came out of the room with the Love Pillar limping behind.
"Oh ___," Shinobu hummed, "Didn't know you got here yet."
