Getting ready for my date tonight, I glide the last swipe of gloss across my lips, the sparkly dress riding so high I can already feel the cool air kissing the bottom of my cheeks. It's been so long since I've been on a date, and I want to look perfect. Coming out to show my StepSon, I ask "What do you think?" I give a spin in my dress, and a teasing little wiggle. Your jaw is clenched. “You look... amazing!” I start to laugh, but I suddenly stop when you step closer. "I don't want you to go," you plead. My heart tumbles... because I know that voice. That’s the same voice of need I know so well. It's just been us together for so long. And you don't want anybody but you to keep me company. I try for step-mommy-tone: "Don’t be silly, sweetie". You step even closer to me, until I can feel the heat coming of your body. "I'm all grown up now. I want you. Tonight. Not some stranger." The confession slaps the air out of me. “I... we can’t,” I whisper. But I’m already inching closer, my glittery dress brushing against your chest.. "Tell me you don’t feel it," you dare. I can’t. Without understanding, I start to confess. I must have failed you as a StepMommy. I remember every single morning you climbed into my bed, your boner poking me and pressing into me without you even realizing. How I’d "accidentally" rock my hips so it would touch my pussy while you cuddled me in bed.. I can't believe these thoughts are actually coming out of my mouth, and right before my date! Despite myself, I can't help but want him to see me slide down the top of this sexy dress to get another chance to see my breasts. "This is my fault. I must have breastfed you too long. You just loved it so much I didn't want to stop. I'm so sorry I ever took these away from you,” I giggle, nervous and excited for you to see these titties again. "I remember wondering how warm you’d feel inside my mouth. Now I finally get the chance to actually taste you." Before my brain even votes, I'm on my knees, and your zipper purrs open. "I used to rub myself under the sheets when you pressed against me," I whisper, my breath hot on the your cock, now swollen and now staring at me. My tongue circles, StepMommy’s mouth welcoming you home. You groan for me, and I’m lost. I pull the dress up to my waist, exposing the fact that I am not wearing any panties tonight. I mount you, sinking down onto your cock, my pussy stretching to take all of you. Completely overcome in the heat of the moment, I grind back and forth on you until you bury your cum so deep I swear I feel it splash my cervix. I freeze, dizzy. "Oh God you didn’t pull out. I could get pregnant!" I stagger up, smoothing the dress, voice shaky: "I still have to go. People will ask questions if I cancel. This isn't right. We... just can’t be together. I still need to go on the date tonight, even if I have my StepSon's cum side of me." Weeks later, I have a new confession to tell you. I'm pregnant, and it's yours. I've known for a couple of weeks. My breasts have become so full, and my milk started coming in. Now I have to keep dating that other guy so people will think it's his. It's the only way we can pull this off and keep doing this. I don't want to stop. In fact, don't you want to taste my milk. After all, you helped create it.
