Erin has me on knees and elbows on my bed, well, knees and elbow, really, since I'm reaching with one hand to claw at my own thigh. She's kneeling behind me, her ring and middle fingers buried deep in my pussy, her hand kneading me, her thumb pressed against the cleft of my ass. She's squeezing her hand shut, pressing inside, massaging the back wall of my vagina, and I'm squirming, my breath whistling between my lips, because she hasn't stopped for about fifteen minutes. Her other hand reaches beneath me, her fingers spreading my lips open, her middle finger fiddling with my clit and sometimes slipping into me alongside her other fingers. Occasionally she stops the kneading, quickly shoving her two fingers into me again and again, the heel of her hand thumping against my pelvic bone, and just when I start to pant and moan it's back to the deep, slow, maddening massage. I can't stay kneeling anymore and collapse to the bed, and her hands retreat for a moment. She rolls me on my back and her hands touch my knees, spreading them, so I reach to grip my legs in my hands and pull my thighs up and out, spreading as wide as I can for her. She just starts again, slipping two fingers into me with her palm down, her thumb slipping up my crack, briefly pausing to rub against my sphincter, which makes me gasp softly. Her other hand inverts, her palms apart, and she slides the middle finger of that one between the other two, making what feels like a bony, triangular cock. It feels fantastic, and I tell her so. "Glad you like it," she whispers, smiling, pressing her fingers deep, deep into me, filling me, stretching me slightly, oh, heaven. I open my eyes, looking at her, and she's grinning that grin, and I just freeze, holding my breath, and she slowly works her fingers in and out of me. I'm clenching and relaxing my buttocks each time she presses with her hands, pushing her three fingers deeper into me, stretching me open, and I grunt a little when it hurts once. "Too much?" she asks, and from the smile she has on her face I know she knows what I'm going to say. "No," I whisper, quivering, my thighs shaking once, sore from being held open like that, but I can't let go, not while she's doing that to me, "don't stop." She does stop, though, sort of - pulling her top hand out, and slipping three of her lower hand's fingers in, all at once, and I gasp, freezing there, feeling her press gently into me, too far, not far enough, and I whimper at her. "More..." My voice high and strange, my hands slipping from my thighs to slide up my torso, clutching at my breasts, and she hooks one of my legs around her waist and spreads the other open with her free hand, slowly working her fingers deeper into me. They feel bigger this way, her middle finger wrapping around her ring and index, and that's OK with me. I'm gripped by a sudden urge to see it, see them in me, and I squirm my way up on my elbows to look down, seeing her hand up to her last knuckle in my slit, the skin of her index finger slick with wetness, my flesh stretched tightly, bright pink across the bone of her finger. Her thumb points up, flexing gently with each push, working to keep her hand curled as tightly as possible, her pinky shoved down against my slit, just touching my ass. "Mmmm," I breathe heavily at her, staring at her hand in me, feeling my lips stretch around her fingers, "harder." "Ssh..." she quiets me, "relax. We're just getting started." I lay back and close my eyes, trying to relax, trying to open up somehow, let her in. She presses deep, spreading her fingers inside me, wiggling them in me, and I can feel it coming, on the outside, skirting the fringes of my awareness, a gentle throb against the smoother waves of pleasure. Erin moves, leaving her hand thrust against me, shifting her body until she's lying across my thigh, her face near my belly, her arm across my ribs, holding my other leg open. Her breath washes over my clitoris, and I shudder, a long, low groan escaping from me. I reach to claw at her back, my hands moving to clench in her hair, trying to press her down, and she does move some, kissing slowly and softly below my navel, then downward, again and again, until her lips close on my pubic hair, pulling gently, and all the while her hand is pulsing, pressing, working against the resistance of my tightness. She spreads the top of my lips open with the tip of her thumb, her tongue touching my clit then, and I sob, warm wet of her tongue like fire, sending a shock up my spine, my back locked in an arch, my breath hissing out between my teeth, and she licks again, and again, and again, each time the contact sending a jolt along my bones, until her lips close softly over my clitoris, and she begins to suck. With a great, shuddering motion, I felt myself climax, somehow disconnected from it, suddenly breathing in huge, ragged gasps, sensations blending, awash in the throes of my orgasm, and then she pushes, curling her fingers in me, kneading me inside and out in the firm grip of her hand, her lips closed around my clit, her teeth nibbling at it...oh and her hand rubbing against me, in me, her index knuckle rubbing strongly against me ...and I hear myself cry out in pain, her palm pressing against the outer gate of my labia, my vagina closing tightly around her, her mouth sucking softly at my erect clit, her fingertips exerting that weird pressure against my cervix, her teeth scratching maddeningly here and there. I feel her curl her fingers inside me again, feel her pull my clit into her mouth, stretching the skin there even further, until her tongue flicks against it inside her mouth, and her hand presses even deeper into me, stretching me until I'm sure I'll tear open. "Let me see let me see let me see" I mutter indistinctly, but she seems to hear, moving off of me, her arm reaching to lift my head, until I can look down, seeing my clit stiffly erect against the base of her thumb, her fingers completely inside me and I watch, almost distantly, as my hips buck and feel it when I came again, seeing the fluids from my climax seep out around my stretched lips, making her skin glisten. She leans over me and kisses me, and I can taste myself in her mouth, and it makes my stomach flutter. I kiss her back, licking, sucking, wanting her more and more, her tongue cool and slick in my mouth. The ball of her thumb rubs gently at my clit, her three fingers gently massaging my insides, and I let out a moan that surprises me, deep and long, like it comes from my soul. I pull hard on her tongue and lips so she doesn't pull away, but it doesn't seem like she's going to, so we kiss and kiss and kiss, her hand still in me, moving slower, her kisses more gentle, slower, until she pulls just away, and kisses my lips gently, smiling, her breath sweet and hot against my face. I gaze dreamily at Erin, sipping tea, curled in my big fuzzy robe in the corner of the couch. I'm pleasantly tired, and just a little sore, but I don't give the smallest part of a flying fuck about that. I'm still trembling. She's tugging her jeans back on in the bathroom, her torso still bare, a towel wrapped around her head. She's so beautiful. And then there's a knock at the door. Fuck. Erin comes out, smiling softly at me, reaching to her head to rub her hair with the towel. "Want me to get that?" she asks, and I reluctantly nod. She drapes the towel over her shoulders and opens the door, admitting Adam. "Hey," he says, his eyebrow raising at her. He looks at me, and smiles. "Hello." "Hi," I answer meekly, feeling my face blush. "What were you two doing?" he asks, smiling wryly. "Having wild sex," Erin says, quite serious, and he bursts out laughing. "Yeah, right. Next time, wait for me, huh?" "Absolutely," Erin promises him, smacking him on the ass with one hand while pulling the towel off her shoulders with the other. Adam's eyes go right to her bare chest. Slut. Bastard. I giggle. "Erin!" I scold, reaching out with one foot to stab at Adam's thigh with my toes. "And you, put your tongue back in." "Back -" begins Erin, and I finish with her, "in where?" and I laugh as she whirls to stride back into the bathroom, an evil grin on her face. Adam, my lovely boy, quite obviously watches her go, a grin of his own forming in the process. "What's gotten into you?" he asks, still looking at Erin's ass. I can't even answer that, so I just laugh again, and I hear Erin chuckling from the bathroom. He sits next to me, leans to kiss me, and I try to suck his tongue out of his mouth. Erin comes out again, smoothing her shirt, smirking at us both. I don't believe it comes out of my mouth, but it does. "Erin's fingers got into me." I say it quietly, but Adam hears, and turns to look at me. His smile is gone. Erin sits opposite him. "No shit." He doesn't look altogether happy, and I call myself a few names for saying that. What the fuck am I thinking? "No shit," I say, taking a deep breath. He stares at me, and for the first time since I've met him I can't tell what he's thinking. A few moments pass, and then he doesn't quite smile. "Next time," he finally says, softly and slowly, "wait for me." Erin catches my eye from behind him and winks, a smile curling the corners of her mouth, and I echo it to both of them. "I promise."
