Female led relationships discussion

My long-time best friend was over at my place with my girlfriend about two weeks ago. We spent time playing video games and hanging out, while he and I drank a few beers until she grew tired and retired for the night. Roughly fifteen minutes after she went to bed by herself, her text came through: “come here.” Walking into the bedroom, I heard that familiar buzzing sound. In the room next to where Scott and I were sitting, my girlfriend was lying naked with a vibrator on her clit while a dildo moved in and out of her. Amused, I approached and asked what she was up to. She looked at me like an eager puppy and replied, “being naughty… Do you wanna have sex with me?” My immediate reaction was to glance at the door: “Scott will hear us!” At this juncture in the story, my brain must have emptied itself into my penis because I don’t recall every detail perfectly. However, she mentioned something like, “would you want to have sex in front of him?” Initially hesitant, the excitement of having an audience for our beautiful lovemaking won me over. She lay back down and continued pleasuring herself while I went to ask my best friend if he wanted to watch us fuck. He had always liked her; once, when drunk, he confessed she was among the top three prettiest girls he’d ever seen. As a quirky guy, he would often “jokingly” request a threesome. After enough banter, it seemed real. I undressed in our bedroom and led my naked girlfriend to the door where she paused hesitantly. “Maybe I don’t want to do this anymore,” she said. “You’re beautiful, and he’s going to love watching us have sex,” I replied. She followed me into the living room where Scott was sitting on the couch in his boxers under the dim lighting. I placed her gently on the floor and positioned myself above her, my erection throbbing with excitement. At first, I moved very softly, but as time went on, my enthusiasm grew, and I began thrusting harder. Eventually, she stopped me and whispered into my ear, “should we let Scott touch me?” I giggled slightly and said, “I don’t know.” After some more nervous chatting, I leaned up from her body and addressed him: “Scott, would you like to suck on her nipples?” Before I could even finish saying ‘l’ in nipples, he was there, licking and kissing her breasts—breasts he had surely imagined kissing a thousand times before. I continued fucking her while he kissed her upper body all over. She looked ecstatic. After several minutes of this, I pulled out and asked if he wanted to lick her pussy. He’d once told me how much he adored going down on girls, especially more so with her than any other girl I had tried it with. Her taste and smell are amazing; her lips are soft and smooth, but best of all, she moans erotically in pleasure, which never fails to swell my cock. As he went down on her, I kissed her a bit more and whispered about how thrilling this experience was. My cuckold fantasies started kicking in slightly. I murmured into her ear, “I’d love to watch you suck his cock.” She shifted her face toward his hips and wrapped her soft lips around his dick, beginning to slide up and down. She is an incredibly beautiful girl but very shy. In fact, she had never dated anyone when we met at age 21. She was a virgin who only kissed one other boy besides me, and certainly hadn’t had any dicks in her mouth before tonight! After about an hour since I first brought her into the living room, I could see she was getting tired. “Do you want to come honey?” she asked. “Of course I do!” I replied enthusiastically. She bent over, and I began taking her from behind while she continued sucking my best friend’s cock. After a few minutes, he asked if he could lie beneath us to lick her pussy and balls as we fucked. We gladly allowed it! After another ten minutes of that, I finally climaxed. Scott insisted on finishing alone because he was too nervous to cum in front of us. So she and I cleaned up and lay in bed snuggling until she fell asleep.
