[FFM] My best friend talked me into being a sub for a threesome with her boyfriend

During my (Tori, F21) Junior year of college I lived in an apartment with 2 other girls my age, Cassandra and Nikki. We were all close friends, having known each other since we were freshmen. We did our fair share of partying, clubbing, and all of the debauchery you would expect... and we all happened to be bi. This didn't amount to much, other than a few times that Cassandra and I made out when we got drunk. At this point in time, Cassandra was dating Rob (M20).

Cassandra shocked me one evening when she came and knocked on the door to my room. I invited her in, and she dropped a bombshell on me: She wanted to know if I would have a threesome with her and Rob. Not just a threesome, but they wanted me to be submissive during so they could "really show me a good time." I didn't know how to respond initially as this proposition came out of the blue. On the one hand, Cassandra is gorgeous and I would hook up with her in a heartbeat if she asked. She was short and petite, with olive colored skin and beautiful black hair. She had a face for the movie screen, and a beautiful voice that I could listen to forever.

On the other hand, I wasn't sure how I felt about Rob. Rob was a few inches over 6 feet tall, thin but strong, and lanky but with a solid frame. He was the guy who played lacrosse and wrestled in school, but was also a nerd who played the saxophone and did close-up magic. He was physically attractive and I found him funny, but I had just never thought of him in a sexual way.

I asked Cassandra to give me time to think about it, and of course she respected that. I mulled it over for a couple of days until I realized that we were hosting a party at our apartment that Friday night. I told Cassandra I would do it after everyone went home Friday, once I was feeling looser from drinking and having fun. She was ecstatic, and assured me that I would have the time of my life in their bedroom.

On the night of the party, Cassandra started a clever little scheme to get me into the mood. I didn't realize what was happening, but in hindsight it was obvious. She would grab me to come take shots in the kitchen, where lo and behold Rob was waiting with 3 shots of vodka ready to go. We toasted, downed our shots, and then as my eyes were closed to deal with the burn Cassandra grabbed my face and kissed me. She made out with me for a good 10 seconds, then let me go and grabbed Rob and started making out with him. I was left standing there, flustered from how her kiss affected me and longing for more. The two of them just kept making out, leaving me to walk away with the warm, happy drunk feeling increasing in tandem with my arousal and longing for her.

Cassandra and Rob repeated this process several times, classically conditioning me to want them, until the last guest left and I was absolutely fiending for more human touch.

"It's tiiiime," Cassandra sang to me. "Rob and I are just going to take the trash out, you should go wait for us in our room." She winked at me, and I beelined through their doorway and stood there looking around. I spied a couple of small sex toys, a box of condoms, and a small bottle of lube. Impressed by their preparation, I decided to take my clothes and underwear off and hop on their bed.

I waited on top of their thick duvet, on my knees completely naked. When they walked into the room, they stopped short and gave a collective sigh together.

"Good girl, Tori!" Cassandra exclaimed, looking up at Rob who gave a wry smile in return. "Let me join you... Rob, would you help me please?"

Cassandra started removing her top and bra while Rob bent down and dropped her skirt and underwear down to her ankles. She stepped out of her bottoms and then started approaching me. I could feel myself in wonder as she climbed onto the bed, padding towards me with feline grace. As she reached me she wrapped her arms around my waist and kissed me delicately. I was in bliss, feeling her soft skin against mine while her lips pressed into mine with increasing intensity. Soon, I was taking sharp breaths through my nostrils as I became more and more turned on.

I felt a weight on the mattress that could only be Rob joining us. Cassandra must have felt it too, because without a word she pushed me onto my back. I fell awkwardly and landed with my legs splayed out in front of me, with Cassandra in between them.

"I've been dreaming of this," Cassandra purred. "Have you been wanting me this way too, Tori?"

"Yes... yes, please, I want you. I'll do whatever you want," I whimpered. Cassandra dropped down to my navel and started licking in short, energetic strokes. She made her way down to my thigh, very quickly reaching the space between my legs. I closed my eyes as she begin to softly lick at my clitoris, allowing my body to relax completely.

Her lips begin to pucker as she kissed and sucked on me, and my eyes shot open when she began to moan. I saw Rob had gotten behind her and had buried his face in between her cheeks, eating her out from behind. The vibrations from her moaning added even more stimulation for me, and I couldn't stay quiet. Soft, little cries came out of me until I felt a sudden pressure inside of me that pulled out a small shout.

Cassandra had inserted a finger inside me, and was crooking it up as far as she could go while continuing to suck and lick at my clit. I tensed up instinctively, and my legs jerked around a few times in response. I placed one hand on top of her head while gripping the pillow with my other.

"Fuck, Cass... Cassandra, please don't stop," I whined. "You're amazing, you're amazing, you're amazing!" I called out in a crescendo that matched the rise of pleasure that had spread throughout my lower body. I shuddered and then went limp as she brought me to climax, leaving me gushing all over her face and onto the covers.

"Your turn, babe," Rob said as he pulled back from his girlfriend's pussy. He gave her ass a spank and she yelped, diving forward up the bed to land next to me and turning over on her back. I lay there and watched as Rob followed her and positioned himself between her spread legs. It was the first time I had seen his dick before, and it was fully erect. It was one of the biggest I had seen in person, and I couldn't really do anything but stare.

"Tori. C'mere," Rob said assertively. He beckoned me with his finger, so I got up and scrambled over towards him. He held out his hand palm up, and issued an order: "Spit." I looked up at him, then down at his hand and spat a small amount onto his palm. He cocked his head and looked me disapprovingly, then moved his mouth over his hand and let out a long trail of saliva. "Like this... I know you have more than that in that slutty little mouth of yours," he taunted.

I pouted for a second, then summoned everything I had in my mouth and drooled into his hand. He moved his hand down to his cock and started rubbing our combined wetness along the length. "That's much better, girl," Rob said. Suddenly the same wet hand I had just spit in reached up and grabbed my face, pinching my cheeks and forcing me to look at him. "Now watch me fuck your best friend, and don't get scared. I'm going to fuck you even harder when I'm done," he growled into my face.

I had never seen this side of Rob, and it did scare me a little bit. I looked over at Cassandra, but she was smiling with pride at her boyfriend and eagerly awaiting his grand entrance. I watched as he thrust his large cock inside of her, causing her to give a deep groan of exertion. He began moving in and out of her at a medium pace, already slapping his skin against hers.

I had heard them from outside their room before, as Cassandra was never one to try to be quiet. Hearing her borderline scream in person was a new experience though. I watched her take the massive length, and it turned me on more than ever before. I laid my head down on her belly and started rubbing her clit, my head facing Rob's thrusting pelvis.

"Fuck her. Fuck her good, Rob, show me how it's done," I said almost angrily. I wanted him to feel how much I was riled up, how much I wanted to be a part of whatever depraved sex life they had. "Finish her off, make her cum, please! I need you to give me what you promised me, to fill my greedy hole and make me your pet. You two can fuck me whenever you want, just PLEASE use me!"

Rob started slamming into Cassandra, spurred on by my mindless dirty talk. I kept saying whatever came to my head, whatever I thought would make him feel a need to prove himself as a man. The whole time, Cassandra just kept yelling obscenities. At some point, she reached down and grabbed ahold of my thigh and dug her nails in while calling out my name alternatively with Rob's. Soon she was finished, declaring her orgasm so loud that it must have been heard outside the apartment.

Cassandra lay there gasping and panting, while Rob took a break to wipe sweat from his brow. She collected herself, and slowly rolled off the bed onto her feet and started shuffling towards the door.

"I'm... going... to get some water for everyone," she wheezed. She stopped by the door, and looked at us both. "Don't stop the fun on my account," she added with a grin, then disappeared into the hall.

I looked at Rob awkwardly, and he looked at me with a stony expression and a fire in his eyes. He lurched towards my feet and grabbed me by the ankles, yanking me a foot down the mattress so I was flat on my back. He leapt over my body and landed straddling me, grabbing my wrists and pinning my arms to the bed by my head. I had just spent the last few minutes egging him on, telling him how much I wanted him to take control and dominate me, and yet in that moment I wondered if I had bitten off more than I could chew.

Rob looked at me, defeated and helpless beneath him. He then bent down and forcefully kissed me, a sloppy and rough kiss that turned into a complete assault by his tongue into my mouth. I moaned as he bullied my tongue with his own, feeling violated by the wet, muscular flailing in my mouth. He finally released me, both mouth and arms, and shuffled back far enough to grab my hips and flip me neatly over onto my stomach. He then grabbed my hips and lifted my ass into the air, placing me on my knees while my upper body collapsed into the mattress.

"This pussy is mine, Tori," Rob snarled as he took a firm grip on each of my ass cheeks and spread them. The indignity was growing, and yet I was unable to stop my arousal or silence the desperation in my head. At that exact moment, Cassandra returned with cold bottles of water.

"Oooo what did I miss!" Cassandra squealed. She handed a bottle to Rob and then came down to lowly me, unscrewing the cap and placing the bottle to my lips. I sucked in as much as I could, replenishing as much fluid as possible. Cassandra then went over to the nightstand and opened a condom wrapper and grabbed the squirt bottle of lube. While Rob kneaded my behind, she opened the condom and rolled it onto his still stiff erection. She squirted some lube into her hand and rubbed it all over the condom, with some of it leaking down onto the covers. "All set to go, baby, make 'this pussy mine'," she said, imitating his declaration of ownership that he had issued to me when she walked in the room.

Rob released my ass and gave it hard slaps with both hands, then guided his cock right into me. I admit, I bellowed in a very unladylike way as he shoved it all the way in on the first thrust. I almost felt like I had been punched in the stomach. He glided in and out of me, striking the very deepest spot I had again and again like a sledgehammer. I gripped the covers, I slobbered on them as my jaw went slack, and I lost all power of speech. Ragged breaths and moans were all that escaped me, and my vision blurred as I struggled to keep my mind focused. Cassandra laid down next to me and started whispering right into my ear as she rubbed her hand on my back.

"You're doing so well, Tori. Aren't you glad you said yes? Aren't you so glad you let me bring you in here to be broken by my boyfriend?" Cassandra said gently and softly. The contrast of her sweet tone and the violence that was being done to me from behind only sent my mind spiraling further into an abyss. Satisfied with the state of me, Cassandra rolled away from me and grabbed one of the small vibrators on the nightstand and turned it on. She began playing with herself while watching Rob fuck the ever-loving shit out of me.

I didn't last long. I wasn't able to warn Rob, I just felt a massive tightness fill my body and I groaned like an animal. Rob also groaned, although with some slight discomfort as I squeezed his cock inside of me while shaking like a leaf. I came hard, and when Rob pulled out of me I just went limp and laid there with my head spinning. I felt the tap of a cold water bottle against my face as Cassandra began nudging me with it.

"You need to finish off Rob, now," she said in a fluttery voice, still vibrating the toy against her clit. "He deserves to cum, and need to suck his cock until he does." Rob had moved over and flopped down on his back with his head between Cassandra's legs, laying there with his dick straight up in the air. I chugged the rest of the water I had been given, then dragged myself over to his torso.

I didn't think at all, I just opened my mouth as wide as I could and started going down on him. Somehow, through all of my exhaustion I found it incredibly easy to relax my jaw and throat to start taking his cock all the way down to the base. He seemed surprised, or at least the noise he made expressed some sort of unexpected sensation. I bobbed my head vigorously, trying hard to use my tongue as I completely coated him with my saliva until it bubbled around my lips and started dripping all over him. It was sloppy, gross, and I was having the time of my life.

"Slobber on my cock, Tori," Rob rumbled. "Pay me back for fu- ugh- fucking you like you wanted. God, you're so good at this..."

I moved my lips up to encase his head and frenulum and started sucking while swirling my tongue around the underside. I grasped his shaft with my other two hands and started rotating them while moving up and down. I could feel his dick stiffening in my hands, and I could even feel his head swell in my mouth. He didn't say a word, but I could tell the exact moment his orgasm began. A split second later, I felt the hotness of his semen shooting into the back of my throat. He still said no words, but as he came he gave out a primal grunt with each spasm of his cock: "Oooooh... ooohh... oooooh..."

I swallowed all of it, all while continuing to stroke his dick so that I could squeeze his cum straight down my esophagus. I finally came up for air and cleared my throat, looking up at Rob and Cassandra as she cradled his head in her hands. It seemed she had taken care of herself while I took care of Rob, so we all just laid around in the afterglow of just too much fucking.

Rob and Cassandra both gushed over how great I was, and how glad they were I joined them. I told them I was going to be sore but it was worth the adventure. It was nice to see Rob soften and treat me as gently as Cassandra did, after all of the brutishness he had displayed when we were all engaged in the heat of the moment.

We stripped the soaking wet duvet off the bed, and Rob fell asleep almost immediately outside the sheets. Cassandra and I cuddled with each other, kissing and giggling softly as Rob snored. We swore we'd shower off, but before we could get around to it we had fallen asleep with our arms around each other. It was just my best friend and I intertwined, having had one of the best nights of our lives.
