"Oh, fuck me!" My roommate's words bleed through the thin walls of our apartment. Stuttered moans echoing in response.

My own hand is stuffed in my pink cotton panties, rubbing my clit in envious circles while taking quick, shallow breaths. My nipples ache as the fabric drags over them. I've got my index finger between my teeth, not to stifle moans...

"You like that you little... um... slut?" Her boyfriend stutters through.

My hand stills as my shoulders begin to shake. I'm laughing. Poor bastard. He's been trying for weeks to scratch Lily's kink but he's too damn nice.

I get it. Not everyone's built for dirty talk. But she's basically writing his lines and he still chokes. It's like watching someone try to curse in a second language. Painful.

But also kind of... endearing? In a pathetic puppy way?

Christ, I need to stop psychoanalyzing my roommate's sex life and get back to...

"You're gonna take it all, okay?" He grunts. The faint slap of their bodies seeps through the walls.

"That's right." She huffs, "make me take that dick!" She growls.

Oh, god. I wipe a tear from my cheek as I resume rubbing my heated cunt.

Marcus isn't bad in bed. I've heard enough genuine moans to know. They've been at it nightly since he moved in. Lily told me Marcus has only been with two girls before her. Both long-term relationships where 'adventurous' meant her on top. He's trying. He's just... failing spectacularly.

Lily's breathless moans mingle with his grunts. "Shit, you feel so good, Marcus." The confession makes my cunt throb. I'm two fingers deep now, the wet slap of my hand matching their rhythm. Don't even care if they can hear me.

A pause from the other room. Shifting into what must be a different position.

"Now call me a whore!" Lily demands.

His grunting returns. Huffing with each thrust. Good intentions vs. dirty demands. The conflict on his face must be brutal.

"I'm gonna make you my little..."

Say it, Marcus. Whore.

Nothing. Just that frustrated growl.

He needs help, and Lily clearly can't teach for shit.

Screw it.

I kick off the covers and sit up, swinging my legs onto the cold carpet. Three steps to my door, panties warm and damp between my thighs. Her door's right across from mine.

I don't knock.

The room reeks of desperation. Sex and sweat and something thick enough to taste. I was knuckle-deep in myself thirty seconds ago, and now I'm standing in their doorway like an idiot. About to do something insane.

Lily's room is a disaster. Clothes everywhere, bed shoved against the far wall. That's where I look first. The window above it lets in just enough streetlight to see everything.

Lily's on all fours, her tits swaying with every thrust Marcus gives her. He’s behind her, and I get a full view of his naked backside. In decent shape. A little hairy. Brown hair tousled with sweat. They're both facing away from me, which means they haven't noticed yet.

Am I really doing this?

Then Marcus shifts and I catch a partial side profile of Lily's flushed face, her mouth open, panting. My gaze drags down his body. The curve of his ass, the flex of his thighs as he drives into her. And yeah. Yeah, I'm doing this.

I squeeze my thighs together, everything clenching. Screw it. Horniness wins.

They both turn and see me.

Marcus freezes mid-thrust. He goes rigid, pulling out fast, scrambling for the throw pillow to cover himself. He freezes up completely, shoulders to his ears, looking guilty as hell.

"Hannah? What—" Lily begins.

"Zip it, bitch." I point at her, glaring.

Lily's mouth drops open, then snaps shut. But when I hold her gaze, something shifts. Her pupils dilate, dark spreading through hazel.

"You two have been screwing for weeks! I know because you're loud and I touch myself listening." I step closer, navigating through scattered clothes. "But you two suck."

I'm standing at the right side of the bed now, the side closest to the door, within arm's reach. This close, the heat radiating off them makes me sweat.

"Lily. Ease Marcus into this. It's obvious he's not used to calling girls he bangs whores..." I hunch down, level with her. Her skin is flushed, damp with exertion. I can smell her. Really smell her, that raw musk underneath the perfume. My cunt throbs. "Slut."

She shudders. Something dark flickers across her face. Aroused. Hesitant but interested.

"Marcus." I stand upright and look at him. His face still registers shock, but his fingers are digging into that pillow like his life depends on it. "Stop being a bitch. She's telling you what she wants. Give it to her. Imagine someone you dislike if that helps."

"I... um, okay." He nods, swallowing hard. His Adam's apple bobs.

"Good." I reach out and snatch the pillow away.

And there it is.

Marcus's cock, hard and flushed and right there in front of me. Dense. Thicker than I'd imagined during all those nights with my hand between my legs, wondering. A prominent vein runs along the top of the shaft, and it's practically twitching under my gaze.

My thighs quiver. Jesus Christ.

All those nights wondering. No wonder Lily sounds like that.

My hand's on him before I decide to do it, fingers wrapping around hot, slick skin. God, he's throbbing. I can feel his heartbeat through that thick vein. "Get back in her."

Marcus makes a choked sound, half gasp, half groan.

"Relax," I mutter, guiding him forward. Lily's still on all fours, watching over her shoulder, dark and hungry. I line him up with her wet, swollen pussy and push him in. Lily gasps. Marcus groans deep in his chest, his hips jerking forward involuntarily, burying himself completely.

I don't let go right away. Can't. My fingers linger at the base, feeling where he's sunk into her, before I let go. My fingers are slick now, sticky with her arousal. I wipe them on my tank top.

"Now." I grab his wrist and place his hand on Lily's shoulder. "Hold here and drive with your hips."

I slap his ass hard enough to leave a mark. That does it. His hips snap forward, Lily moans.

Marcus keeps pounding her, finding a rhythm, his hand gripping her shoulder like I told him. The wet slap of skin fills the room, punctuated by Lily's gasping moans, and I feel it in my pussy. Every thrust, every sound. My hand lingers on his ass, fingers digging into the muscle because screw it, I'm gonna get what I can out of this.

Lily's looking over her shoulder at me, staring with pleading desperation.

"Hannah..." Her voice wavers, needy.

"Shut it, whore."

A whine spills from Lily's throat. High-pitched and desperate. And Marcus's hips stutter for half a second before resuming, harder now.

"See how she reacts?" My hand's still on his ass, feeling him work. "She loves it."

He nods, breathing hard through his nose, and his rhythm picks up. More confident. His other hand finds Lily's hip, gripping tight enough to leave marks.

I walk around to the left side of the bed. Perfect view now. Lily's wrecked, flushed, panting. Marcus is focused, jaw tight, watching his cock sink into her over and over.

"When she tells you to spank her..." I grab his hand off Lily's hip, plant it on the curve of her ass. "Rub here first. Build anticipation."

I guide his palm in a slow circle, watching her flesh dimple under the pressure. Marcus's hips don't stop moving. He's still buried in her, steady and deep, while I teach him how to touch her properly.

"Then..."

I bring his hand down hard.

Thwack!

"Commit."

Lily coos and shudders, her whole body clenching. Marcus groans, guttural and raw. His hips stutter as her pussy clamps down on his cock.

"Start light, work your way up. She'll tell you when it's too much." I stare him down. No more shock. Hunger radiates from him now. "Give it a try."

His hand raises.

Thwack!

Lily yelps. She bends her back, and he holds her shoulder tighter. He's really pounding her now. No uncertainty. Just hard, confident thrusts that make her gasp.

My nipples ache. I twist them hard through my tank top, pinching, pulling. Still not enough. It's never going to be enough until I get my fingers back inside myself.

"Good girls use their words, Lily. Tell him what you need."

She looks back at him, breathless, completely glazed. "Please," Lily gasps. "Please, Marcus, spank me harder."

She sounds so damn sweet when she begs. I nod at Marcus.

Thwack!

"Oh god! That's it!" Lily's chest drops to the mattress, ass rising higher. She's shaking. And Marcus is just destroying her now. Pure need.

I circle back to the right side of the bed. My cunt's throbbing, slick and desperate, and I'm not touching it. My thighs rub with every step. It's torture.

"One last thing." I'm right there again. The smell of them, her perfume, his sweat. It makes my head swim. "When she tells you to pull her hair..."

I reach out and get a fistful of Lily's hair, wrapping it around my wrist. She gasps, her head jerking back, and Marcus's rhythm falters for half a second.

"Pull."

I yank back hard, forcing Lily upright off the bed. Her back arches, tits bouncing, and her whole body goes rigid.

"Jesus! I'm—holy shit—I'm..."

Her whole body seizes up, shaking hard. Marcus groans deep, hands clamping her hips, pounding her through every convulsion. His eyes are locked where they're joined, and his face... Christ. Transformed. Confident. Hungry. In control.

I just made her come.

Shivers race down my spine. My knees nearly buckle. The audacity of this bitch, coming while I'm doing all the work.

Then it clicks. I pulled that orgasm from her with nothing but her own hair.

Didn't even touch her cunt. Just pulled her hair and she came.

My clit throbs with my pulse. I'm soaked, aching, desperate. Power surges through me. My head spins. Drunk on control, on the audacity of walking in here and making this happen.

I release Lily and step back. She's glazed, unfocused, trembling with aftershocks. Marcus sits up straighter, chest heaving. He meets my eyes, actually meets them. His grip on Lily's hips tightens, jaw setting.

Yeah. That's what confidence looks like on him.

"Now." The word comes out ragged. I'm barely holding it together. "I'm gonna go back to my room and continue fingering myself to you two screwing."

I hook my panties and drag them down, stepping out of them. Cool air hits my scorching cunt. I'm drenched. Can feel it on my thighs. I twist them into a ball, soaking wet, and get in Lily's face.

"Open." I grab her face, fingers digging into her cheeks, forcing her mouth open.

The second her mouth opens, I stuff my panties in. They're drenched. She's tasting me now, whether she wants to or not.

"I don't wanna hear her moan until I hear a proper slap on her ass. Understood, Marcus?"

"Yes, ma'am." Immediate obedience.

I head for the door. Every step reminds me how bare I am, how slick. Every nerve ending is on fire. I'm dizzy with it, the power, the arousal, all of it.

I don't even make it to my room.

A sharp, confident SMACK that makes me freeze in the doorway. Lily's muffled shriek follows, desperate and needy around my panties.

Then Marcus's voice. Low and rough in a way I've never heard before:

"You're going to take every inch, understand?"

My hand's between my legs instantly. I make it three steps into my room before my knees give out.

Tonight I wasn't jealous of the girl getting screwed.

Tonight, I was the one in control.
