Wow! So where to begin? Well, I guess I should say that prior to this event I was really shy. There, with that said it's safe to continue! My boyfriend seems to really enjoy me posting my experiences for others to enjoy. One of my most private fantasies is to have a threesome with my deliciously virile boyfriend and my best friend Grace. They both have an appetite for kinky sex and that would overshadow any hesitation that I might have. But, like I said this is just a fantasy. "Being best friends and roommates we share everything, why not sex?" That was the question sandy-blonde Grace asked me one day while we were working out together. Half-way through the set of sit-ups I completely lost count and just stared at her. I couldn't tear my eyes away from her creamy-smooth long legs and her being the bold, I-get-what-I-want person that she is, made it worse. She's persistent and damn near unrelenting when she knows what she wants and how to get it. My chest tightened and I inwardly panicked to come up with something not to alert her that what she had just said made my nipples hard and my belly tingle. "That's just it, we share everything, can't we just leave sex as one of those things, as few as they might be, that we don't? I swear you come up with this stuff to throw me off balance. Plus, as cute as you are you're not my type." We both laughed as she tried to feign being insulted, tossing back her sandy-blonde hair. I started my sit-ups again. "Well you can't blame me for asking, after all, you didn't expect for us to fool around in high school but we did, and you know you liked it." If there was a rock that I could have crawled under I would have right then. Instead, I continued my reps and acted as if what she'd just said had no effect on me, that I didn't remember the way her tongue felt sliding in and out of me. Whew, my thoughts could get me into trouble if they continued this way. I'd end up on my back, sweaty and moaning, getting-tongue fucked from my best friend. Nope, there's no way I could keep thinking about this. Finally finished at the gym, we made our way to the women's showers. I stripped off my sweaty sports bra and shorts and grabbed my shampoo and towel. Grace was somewhere behind me when I went under the spray of hot water. "Come on, you have to admit it would be fun, and if you want to you can even have your boyfriend watch. I wouldn't mind, and I doubt he would either. What guy wouldn't want two willing girls going at each other? That'd blow his mind. I wouldn't even fuck him if you'd have a problem with it." So I must have been dreaming, or Grace was a mind reader. This was really too good to pass up, even for me. "Well, I'd have to ask him first to make sure that he's okay with this. I don't want to cheat on him, but there's no way I could ask. You'd have to." That said, I turned around so the water hit my back. Grace was there right in front of me in all her naked glory. She took the soap from me and got her hands all soapy and slippery. They moved over my breasts and I shivered. The light touch of her palms had my nipples puckered, and I could feel the slow, insistent heat start to pool between my legs. It really wasn't fair for me to be so responsive to just a light touch. If this continued, I would really have to throw my ideals of not cheating to the wayside, and have something more than these light teasing caresses. Grace lathered me up from head to toe, and all I could do was lean against the wall for support. As her hands continued their descent, tickling and fondling, I gasped as she slipped her hand between my legs. I was wet, and her sudsy hand slid into my folds with ease as she teased my clitoris. I closed my eyes and arched my pelvis towards her. I was rewarded by the removal of her wayward hand, leaving my pussy bereft. "Good, now I know that you want me bad enough and you're not going to chicken out. You really should stop being so uptight and just do the things that you want, like fucking me." What a way to get a point across; I could hardly keep still; all I wanted was to come and frankly I didn't care how it happened. Patience is a virtue. That's what I kept telling myself for the week that passed without any more talk of the "supposed threesome". Truthfully, every time my mind wandered I thought about it. When I slept I dreamed about it, and awoke to my panties wet, my heart racing, I touched my breasts, squeezed my nipples, fingered myself til I came. Part of me wanted Grace to walk in on me, naked on my bed, biting my bottom lip trying to not moan as I thought of eating her pussy while I got fucked from behind, rubbing my clit until I shattered and climaxed. I was asleep. I half woke when I felt something lightly encircle my wrist. Still fuzzy from sleep, my mind didn't register that my other wrist was also already fastened quite securely to the posts of my canopy bed. When it set in that I couldn't move my hands freely, I started to panic. It was still pitch black and my eyes did not have time to adjust to the darkness when something went around my eyes, and then my neck. The bed dipped under someone else's weight -- my body went completely rigid. I didn't know if I should scream or be quiet. I groaned inwardly at my lack of discretion. I had no clothes on, and whoever had bound me, and was now right next to me, could do with me as they pleased. My heart was racing and I could neither see nor hear anything else. I held my breath and tried to calm myself. I didn't dare move. I felt someone get on the bed on the other side of me... I tried to determine what would be outcome if I tried to kick and scream my way out. A warm wet mouth covered my nipple. I screamed, but it was smothered in a kiss that took my breath away. "What ever you want you can have it, please just leave me alone. I swear I'll scream, and my roommate will come in here and catch you. Just take what you want and leave." I tried my best to keep the quiver in the pit of my stomach not to affect my voice. I didn't want to sound weak, though I was about to burst into tears any second. "Stop being such a cry baby. This is going to be fun." I was stunned. It was only Grace. From the first word she said, relief washed through my body. As familiar hands traced the slope of my breasts, I could have killed my boyfriend for going along with her in doing this to me. As a feather-light touch made lazy patterns around my breasts, the side of my ribs; awareness blossomed where fear was moments ago. My blindfold now off, I could see everything as the lights were on. Grace was naked; her pale skin seemed to glow under bright light. My boyfriend was naked as well, and they looked too happy for my comfort. I realized, though, I was still bound. There was the hint of a smile playing on the lips of my man, which did nothing to alleviate my uneasy feeling that something bad was about to happen. "I'm only telling you so you don't freak out when I do it, but I'm going to be using a scarf tied around your neck to make your orgasm even better. Sweetie you're going to fuck, and be fucked more times tonight than you ever dreamed." It's a good thing I was already on flat on the bed, because I would have been as I grasped what was being said. One time I had told my boyfriend that I thought the idea of being tied up and forced into submission, being fucked against my will, turned me on. Surely this couldn't actually be happening, could it? But I could feel the tingling and liquid heat start to leak from me. I watched, bound as I was, as Grace bent over the side of my bed, as from behind she was filled with my boyfriend's cock. She moaned as he pumped into her fast and hard. I could see his cock as he let it completely slide out of her, only to slam into her again. He pulled her hair and she begged him to fuck her -- she seemed to like her sex rough. "Fuck me, fuck me, fuck me." She kept on saying it over and over as the sound of his hips colliding with her ass echoed in the room. I had never seen this side of either of them before, and I was awed into silence. I pulled at my restrained wrists. I wanted to touch myself so much it was almost a physical pain that I couldn't. I kept watching as he plunged into her again and again. As he came he pulled completely out of her, she turned around to catch every drop of his cum in her mouth. She cleaned his cock, licked her lips and swallowed. I was so aroused I was sure there would be a wet spot soaking through my sheets to the mattress from my juices. Grace crawled over to me and kissed me deep and hard. It hurt; I could taste the mixture of her juices and his cum in her mouth. "Please untie me, this isn't fair. My pussy feels like its on fire, I'm so fucking wet and I cant do shit about it tied up." I begged, but no one listened as Grace made her way down my body burning a trail with her tongue. Normally not a person to scream and moan really loud as I'm being fucked, I couldn't keep my mouth shut. As her sinful tongue dipped into my slit, I screamed it felt so good. As my mouth opened again, my boyfriend shoved his hard, thick cock into my mouth. Both my hands still bound, my pussy being mercilessly tongue tortured, and my mouth stuffed full of a huge engorged cock, I must have looked like something out of a porn flick. I swirled my tongue around the head of his cock, teasing as I sucked the tip, then ran the tip of my tongue down the sides. When he could no longer take me toying with him, he thrust deep into my mouth going to the back of my throat. I almost gagged: his cock was too big and thick. I felt as if I would choke when he did it again. I sucked with more pressure and he groaned unloading more than one mouthful of his seed as I tried to swallow while about to come. I gulped the last drop when I felt the scarf tighten around my neck. I could hardly breathe. Grace pinched my clit with her teeth. I came so hard, so very hard. Wave after wave of pleasure hit me as I tried to breathe. I floated back to consciousness only to have my boyfriend drive his cock into my still recuperating pussy. I moaned as he thrust into me and my lips instinctively spread to accommodate him. My legs draped over his shoulders, my head back, and Grace's pussy over my face. She was wet and all I could smell was sex. I licked and suckled her clit, just enough to almost make her cum then backing off, frustrating and driving her wild until, unable to take it any more, she smothered her pussy in my face grinding on my mouth. She came in my mouth, and I licked her sensitive lips like a kitten, tentatively and gentle. I could feel my own orgasm building up again, and she kissed me, feather lightly. The tang of sex still hung in her mouth as her tongue invaded mine. She squeezed my nipples, rubbed my clit as I was being fucked without abandon, faster and faster. I was on sensory overload as I climaxed, still bound. My wrists hurt, but my body smoldered in ecstasy.
