This happened a few months ago with me and my lifelong friends. I had come out as bi just the week before. For privacy I’ll call one girl N and the other F. After a day of swimming and drinking, the three of us ended up in bed together with our pajamas on, which isn’t unusual at all. Somehow, the conversation turned to our styles in bed. N and F were teasing me about how much of a sub I am. I was defensive, saying “I can be in charge!!!” They weren’t having it. N has always seemed like the ultimate dominant, but I never saw F that way. She’s so wholesome and sweet.. I couldn’t imagine her in charge. N could never be submissive. Or so I thought. As I tried to turn the focus onto F, I was kinda egging her on, saying things like, “There’s no way your a top, I don’t believe it.” Next thing I knew, F was on top of me and N, a knee between each of our thighs. She said, “I’ll prove it.” I watched her put a hand around each of our necks. (We’d all discussed our enjoyment of being choked) She leaned down and kissed N, her hand still on my throat. I was insanely turned on at this point but in awe of what was going down. It was so playful and seeing F take charge like that made me so proud of her, so I was hyping her up. I giggled and put my hand on her thigh between my legs, saying, “Damn, F, okayyyyy” as if I were cheering her on. To my surprise she tightened her grip on my neck and turned to me to makeout. I’d made out with N plenty of times, but this was my first time kissing F. I couldn’t help but grind against her thigh, which led her to push it into me harder so I could keep grinding. N reached for F’s shirt and I knew there was no turning back. I couldn’t resist feeling her boobs. They were so perfect. I have the biggest of the three of us but the shape of her perfect tits was incredible. I even commented “I never realized they were so big. Can I?” After she nodded, brought my face to her boobs and had my first taste. This was already the furthest I’d gone with a woman. All of my doubts about my sexuality went out the window when my tongue touched her nipple for the first time. There was absolutely no doubt i’m into girls. N joined me by kissing F’s other tit. I wish I could have seen from another view because this scene must have looked incredible. F holding our necks while we played with her boobs in our mouths. Then I felt a hand on the outside of my pj shorts and saw N eyeing me, asking for permission. I nodded and placed my hand over her shorts. This was the first pussy besides my own that I’d ever felt. I mirrored her motions, rubbing circles over the fabric. F’s hands started wandering to the hems of our shirts and almost simultaneously, N and I stripped for her.
