All through my school life, I had known a grand total of 6 girls, having been in an all-boys school. I was a shy guy in general and, due to this, especially shy around girls. You know how guys can be. College was nearing, so I decided to gather some courage and talk to girls just so that socializing would be a little easier in the coming four years. I gained confidence ever so gradually, but it still is hard for me to strike up a conversation initially.

The second month after admissions saw a friend from school, who also was in the same college, dating a girl who lived near by. She was outgoing and nice, albeit a little loud. They were in a relationship for a good two years before they broke up. Throughout, all could see that he was miserable. Outgoing became bossy, nice became nosey, and loud just became louder. She'd pick fights with everyone and try to get things her way at all times. People began to dislike her, but since they were too nice to tell her about it, she tagged along and brought with her the same misery she'd been dishing out to people around her.

I'd seen a fair share of my friends get hurt by her behavior. My aversion to being around her helped as I was never on the receiving end of her tantrums. But watching my friends and their ruined moods riled up my irritation towards her. My girlfriend, Katie, didn't like her either. I'm a nice guy in general (had one minor physical fight till date), but any time that she was around, my thoughts would drift to taking collective revenge for all those people who she's constantly bitched out at. Let me clear that there's no pent up attraction here. Just pent up aggression.

One day, me and a bunch of friends are staying over at someone's place. Katie is there too. Me and her have had the night planned out well enough. The guys hang around with the guys for a while, smoking a joint, while the girls do the same by themselves. After an hour or so, we all gather to drink a bit in the living room. The night rolls on with us playing games, singing, while that girl never stops her loud, incessant talking. After a few pegs, bodies start to heat up, and so do the present couple's passions. You could see them sit really close a while ago, but now they're more drunk with wet passion and lust than cheap alcohol. I'm not much of a singer, and I wasn't drunk enough to become one, so I looked around at places the others were too busy to look at. The guy slips his hands into his girlfriend's top through the back. I couldn't really see that, but the expression on her face changed as she bit her lip and shivered with sudden ecstasy. I nudged Katie and told her to have a look at them, and to my pleasant surprise, she'd already been and was as horny. The couple took leave and walked out rather briskly, giggling and heated up. Me and Katie want to get up too, but we remember our plan.
People began sleeping about 2 hours past midnight. The girl was the last one to remain awake apart from me and Katie. We give each other the signal, after which I get up and excused myself to use the washroom. I instead go into one of the empty bedrooms and look into my bag. The ropes, the whip, the clamps the gag and the strap-on are still there, untouched, waiting to be used. I went down the stairs, pumped up and ready for action.

The girl's back was facing the stairs that I got down from. Katie looks at me quickly, also pumped up and ready for the night. I sneak up behind this mildly inebriated girl, who's name is Monique, by the way, and quickly cover her mouth with my hand. Simultaneously, I hold both her arms behind her back and pick her up to drag her up the staircase into the waiting bedroom. She kicks and lets out a muffled scream, but realizes that everyone is lost in their dreams, while she's stuck in our's.
I drag her into the bedroom with relative ease as Katie shuts and locks the door behind us. Monique is still trying to escape my tight grasp, when Katie comes forward and lands a slap on her face. The shock shuts Monique up while they gaze at each other. I get an instant hard-on, never having seen, in person, such a side of Katie.

"Shut up, or I keep slapping till you do"

She takes the ropes out and begins to tie Monique's arms to her legs while I hold her down. She lets out a whimper, to which Katie lands another slap square on her face. She takes the gag out of our bag, pushes her onto the bed and puts the gag on a struggling Monique. I've never had a bigger hard-on, to which Katie responds by slowly kissing my neck and biting my ears. After a lovely five-minute make out session, we turn our attention back to Monique, who is confused and shocked at the turn of events. We take Monique's clothes off piece by piece as we kiss, letting her know that we're okay about anything today. We make her sit in an awkward position, leaning against the headboard, so that she gets a full view of what we're doing.

"You love to get attention, don't you, you little bitch?? How's this for attention, huh??"

We take each others clothes off in an excited state of frenzy, till we're also completely naked. Monique's eyes reveal an expression of unease while we touch, grab, bite and nibble at each other.

"Your turn, sweetie. Teach her a lesson"

I choke Monique slightly and take her gag off. She tries to let out a scream, but before she can, Katie pulls her hair and whispers into her ears, "Now you suck his cock good, do you understand?? Take it as deep as he gives it. Be the slut you've always been".
I take the back of her head and slowly guide my throbbing cock into her mouth. She's unwilling at first, but sees no escape option but to comply. I let her move her head back and forth, but I suddenly remember why I dislike her so much. Memories make me grab her head and shove my cock into her mouth. She coughs and gags. I slap her, look straight into her eyes, and shove it in her mouth again. A few minutes into this, Monique stops gagging.

"You're getting used to this already?? More of a slut than I had imagined, fortunately!"

Katie came up to me and kissed me passionately again for a minute before going back to the bag. I pulled Monique and pushed her on to the bed and positioned her on the edge with her back on the bed. Katie comes near the edge, slaps Monique on her bare breasts and says, "Lick my pussy clean. I don't care if you can't breathe".
She puts her pussy on Monique's face, to which she lets out a whimper. Katie grabs her neck, sending out a message. Monique gets it and begins licking her wet, pink pussy. I climb onto the bed, position myself near Monique's ass, and put my throbbing cock into her surprisingly super wet pussy. Katie moans and holds my head for support, while I thrust in and out of Monique's pussy. Katie grabs my hair tight and bites my lip as she reaches her first orgasm. Her juices flood Monique's face, who gags and spits out what went in.

"First your cock, now my pussy! She knows how to work them both, doesn't she??"

Katie's body looks gorgeous on the dim light of the room. It reflects off the sweat on her breasts, her stomach and her legs. Her ass looks heavenly in the orange light as she turns around and bends to get her strap-on out. She puts her finger to her lips and makes a 'shhh' sound, as she puts it on.

"You know what to do, sweetie."

I lie on the bed and pull Monique up over me. Katie puts the gag back on her mouth while I hold Monique by her spread legs. Katie lubes up her fingers and puts one into Monique's ass. She tries to scream, but she moans instead. She moves her finger in and out. Finger becomes fingers. Katie then lubes up my cock, and guides it to Monique's stretched but hole.

"Alright, let's go"

I insert my cock at the same time Katie shoves her strap-on into Monique's pussy. Her body tightens from the shock. Katie pulls out the small whip, and hits her breasts. She puts her face beside Monique's and whispers, "A whip on each for every sound you make, bitch. Take it like the slut you are."
Katie grabs Monique's neck with the other hand and keeps moving back and forth. I have never been more turned on in my life. Seeing my calm, beautiful Katie dominating this bitch with me sends my in a frenzy. I grab Monique's butt tightly and begin fucking her hard. She tries to scream again, but a few whips shut her up. To add to the excitement, Katie has her head pointed upwards, sweat all over her, also pounding Monique's pussy wildly. The bed is now shaking quite a bit as I near climax. A surge of pleasure washes through my cock as the pent up aggression slowly makes it's way out of me. Looks like Monique is shivering as she receives the aggression from me and Katie, both.
I can't hold it in any longer. I explode in Monique's ass just as Katie and Monique have explosions of their own. We keep moving till we can't feel our legs.

"How'd you like that, bitch??"

Katie pushes Monique off me, and whips her ass a few times till she's shaking, after which she falls on me. I hold her on top of me with my arms around her, feeling every inch of her quivering body on me. The smell of raw passion, instinct and lust permeates the room as we make out gently this time.

"Honey, we forgot to use the clamps"

"Yeah, I know. I'm not quite done yet. Hope you aren't", she says, with a wink.

She gets up, drinks some water. I drink some too. She takes the remaining water, and spits it on Monique, who is too stunned by the circumstances of what may have been her best orgasm. Katie lightly kicks her ass and comes over to the bed. She looks over at her...

"Round two in a half-hour, bitch. And I don't care if you can't breath"
