A Big Celebration that goes sides for me

Whether it's from my touch or from my words I do not know, but something is released in Geena. I feel her moan, almost see it the sound is so human, has such shape, such pain. I don't know if she's horny or sobbing or what but I feel for her even in my sudden frightened silence. But her hand is gliding down, then the other too, and as they tickle along my ribs I think yes, because this is where the girls finger each other finally. I cross my own arms through hers, finding and grasping her soft relaxed buttocks while she probes at my waistband, and sliding down her shorts as she fumblingly unfastens mine. I have to pull my thighs in so she can take my shorts down, down, and off one foot with my panties along for the ride. Oh god maybe we are going to rub pussies together. But still she perversely holds herself arched. I won't wait any more. I spread my legs wide again, I run my hands around her beautiful hips, reaching for her surely sopping crotch. And her arms are suddenly there between us--they push mine back. I struggle with her, growling in sudden frustration and lust, driven beyond understanding of why she would try to stop me. My hands twist and push, fingers questing toward her sex, but I only manage to graze her sweaty wrist--yet her hands are both on me, higher up my arms, so how--

"Aah!" I squeal in sudden pain. Geena has shoved my arms apart, wrenching my left wrist. She shifts roughly forward and up on one elbow, so that her upper body is half supported on my neck and chest, confining me. Her cheek presses hotly on mine. Her boobs grind her t-shirt into my naked chest. I don't understand what she wants but I'm not in charge, haven't been for a long while. She reaches one-handed between our still-separated groins and does something, touches herself I think, and I wonder, is this her fantasy, to control me and make me do nothing while she masturbates? But no, I feel her fist between my legs, and my face flushes anew at her touch because this will be some kind of virginity, gone in a moment.
