Now who is the slut? (II) SeXStoRY

As expected, Sally accepted Emma's invitation on the condition that we'd watch the latest Twilight movie. Well, a necessary evil, I thought. The days passed by and I noticed Emma getting a little more nervous and excited every day. I knew she was bi-curious and I had also noticed the way in which she used to smile at Sally. In the meantime, the weather had improved, now spring had turned into summer, and along with that sudden transformation, a more spectacular one had occurred. Sally, who used to seem so shy and innocent, had started dating Dave, the captain of her college's football team, a strong, handsome lad. Luckily, our meeting with Sally coincided with Dave's training, so we didn't have to fear any interference from his side really. Emma was wearing a top which was slightly shorter than the one she had worn a week earlier, combined with short pink pants. She had deemed underwear an unnecessary obstacle, so when she sat cross-legged as she normally does, I could enjoy the sight of her tight slit. She had put her dirty blonde hair into pigtails and her beautiful green eyes were shining with eager anticipation. We lived in a small 2-room apartment and as we both loved to watch tv in bed, the flatscreen was placed in our bedroom. We had agreed to meet at 8, and five minutes later, the doorbell rang and Emma rushed to the door and flung it open and gave Sally a hug and a kiss on the cheek to welcome her, while I fetched some more crisps and poured the girls a glass of wine, placing it on the bedroom drawer. For myself, I preferred beer. Anyway, I wasn't going to get d***k tonight, I needed to stay in control of things... Sally was wearing a checked shirt and a mini skirt. She smiled and me shily and said "hi" as she entered the bedroom. "I hope you'll survive the movie", she continued, now in a slightly cheeky tone. "I will, unless I get bitten by a vampire", I replied. "Now why don't you sit in the middle, Sally, so I can pour us the drinks and you can just relax?", Emma asked. Sally complied. I inserted the DVD and started the movie, while the girls had their first glass of wine. Oh, what a lame movie that is, I thought to myself. But today, I would keep quiet, in order not to ruin the romantic mood , which had already got a firm hold of Sally in particular. Apparently, that mood called for more wine. After the second or third kissing scene, Emma refilled the glasses and the girls cheered again. Just that this time, Emma's lips didn't stop at her wine glass, but moved on to touch Sally's. At first, Sally seemed about draw back and protest, but with the wine glass in one hand and my girlfriend's hot lips pressing against hers, she was unable to. I took her glass and put it back on the drawer, just in time to prevent her making a real mess. What Sally didn't know was that I had placed a set of those fluffy "love handcuffs which I had given Emma at Valentine's Day, in the top drawer, together with some rope. With the girls now kissing more intensely, not noticing what was going on around them, I took them, moved closer to the girls and - with a quick movement -seized Sally's wrists and handcuffed her. Feeling the cold metal and the fluffy pink fabric close around her hands, she screamed at me: "What the hell are you doing? Have you gone mad? Open it, now!" But at the same moment, Emma placed her hand on Sally's mouth and whispered into her ear: "Relax, sweetie, this is your night, nobody's going to hurt you!" I could see her other hand move down and disappear underneath Sally's skirt. After a few seconds, Sally started with what seemed like an unidentifiable mixture of gasping, sobbing and moaning and her hips slowly started moving up and down and her breath got heavier. Emma had taken her hand off Sally's mouth and was now using it to open the buttons of her shirt, exposing her perky little tits, which I couldn't help but touch and squeeze slightly. I could see the pleasure in my girlfriend's eyes rise, as she French-kissed Sally, while her left hand was rubbing her friend's clit. I seized the opportunity pulled Sally's skirt down, so I could finally see her in her full glory. She was fully shaven and her pussy, which looked extremely tight, was starting to look wet. I took the rope and tied Sally's feet to the frame of the bed. Now she was completely helpless, a slave of her own pleasure. And of my girlfriend's dirty mind and skillfull tongue and fingers, i thought. Now she complained, not sounding too convincing unable to control her voice and supress the moans: "Stop,ahhh... this isn't right, what's Dave...mmmmmh... gonna say if he finds out?" In an instant, Emma, pulled her fingers - two of which had just entered the opening of other girl's tight slit - out, stopped kissing her and said in a firm voice: "Ok, as you wish!" As she rose, she lasciviously moved over her friend's face, allowing her a full view of her divine love slot, which was completelty shaved except for a small "landing strip", the labia slightly swollen and juicy. Sally's beautiful dark eyes opened wide with what looked like a strange mixture of shock and excitement, as she was lying on her back, unable to move. Instead of moving on, Emma turned around on all fours, her wet opening still right above her friend's face, her round little ass pointing towards me now. She looked at me over her shoulder with that horny look of hers and pulled her pants down to her knees. "Come on honey, what are you waiting for, your little slut needs to be fucked now!" Not needing a second invitation after having watched events unfold, I took off my pants, moved behind Emma and slapped the opening of her pussy with my hard cock a couple of times, every time, she would wince slightly and moan wildly. Then Sally made her last attempt escape: "Emma, why don't you untie me, so I can leave you guys alone, I'm sure Dave's already waiting for me!" "Not now, sweetie", Emma replied, "I'm busy, can't you see that?" And busy I would keep her, I thought, finally letting my cock slide into the wet and warm opening. "Hmmm, I want you to pound me hard, let her see what a nasty little slut I am", Emma yelled at me. I did as she commanded. After a few minutes, I pulled out for a moment, just to get a better view of our innocent little friend. The fear in her eyes had turned into lust and she was moving her hips up and down (as far as she could in her position), then pressing her tiny little ass against the bed sheet, on which I could see a little puddle forming. "Don't stop, fuck me more!", Emma screamed. Her pussy was dripping wet now and I could already feel the first contractions, as I reentered, knowing she was about to reach her climax. "Deeper, faster, give it to me!" That was too much for me. With one hand, I pulled one of Emma's pigtails, with the other, I slapped one of her ass cheeks, pounding her faster and faster. Suddenly, she screamed savagely and I could feel her cunt contracting, in the same second, my cock started throbbing and exploded, shooting loads of sticky cum deep into her. I kept on fucking her for a few seconds, until my cock finally showed some signs of exhaustion. As I pulled it out of my girlfriend's heavenly pleasure hole, a cocktail of Emma's sweet juices, mixed with my sticky sperm, oozed out of it and dropped directly down on Sally's cheeks and lips, which slowly opened, unable to withstand the temptation of getting a taste of it...
