Dmitri’s waiting, already holding the door open for me.

“Mistress,” he dips his head in greeting.

“How was it tonight?”

“Excellent.”

“Good. Shut the door behind me.”

“Yes, ma’am.”

This session is now closed, and I’ve got my boys all to myself.

Knox is tied in multicolored rope across his torso and legs. Kneeling on the bed with his arms fixed behind his back, his dick is hard, veiny, and nearly purple from being edged for over an hour by Vault.

“What color are you, pup?” I set the whiteboard down at the foot of the bed.

“Green as kale.”

He won’t look at me until I give him permission. “Such a good boy.”

Kissing Vault as I pass by, I pluck a riding crop from the wall. Vault already has two soft floggers in his hands.

“He was amazing tonight,” he says against my ear. “He definitely deserves a reward, Mistress.”

“Are you topping from the bottom, Alex?” Because I know he’s not trying to give his Mistress orders right now.

He slaps my ass. “Reward him so I can fuck you.”

God, I love switching roles. We’re so good at it now. And after the long day I’ve had at the lab, this is the perfect way to unwind.

“Eyes on me, pup.”

Knox lifts his gaze, and his face contorts with ecstasy. “Oh. My. Fucking. God. You’re in a lab coat.” He looks at Vault. “She’s in a lab coat!”

“I have eyes, pup.” Vault clicks something in his palm, and Knox lets out a beautiful moan.

Ohhh. Theydefinitelyhad fun tonight.

“He’s so fucking ready to blow,” Vault growls in my ear.

I guessso with that vibrating plug in his ass and the two of us torturing him so badly.

“Atoms…” I slap the riding crop on my filled out white board. “Are held together by electrostatic attraction.”

Knox groans again.

“The force of attraction between oppositely charged particles. In other words…” I unbutton my lab coat to reveal nothing but skin. “A positively charged proton in the nucleus and a—”

“Oh god, don’t do this to me… talking nerdy will…” Knox leans forward and groans, his arms putting tension on the rope hooking him to the ceiling. “Fuck me. I can’t take this anymore. You gotta have mercy.”

“Are you calling Red?” Vault unbuckles his pants, pulling the belt free with one swift yank.

“Fuck no, I’m not calling Red.” Knox pants from his position, helpless and desperate.

Vault bends me over in front of Knox and cracks my ass with his belt.

When the second spank hits, I call out Knox’s name.
