A ragged breath rips from her throat as she rolls her head forward, grunting softly as her next contraction begins to build. Her legs are spread for you, thighs trembling wildly on either side of the bulge of her cunt. No head is visible yet, but her lips begin to gape and spread as her grunts evolve into a small roar, fluid leaking from her hole as she pushes in earnest.
"Ohhhhh," she groans, half delirious. "Oh, its- OH. It's comingggg." Her nails dig into the flesh of her thigh, face screwed up with effort as she pulls her leg further back. Her cunt bulges obscenely around the emerging head and more fluid leaks from her vagina, coating your fingers in slick as you reach forward to slide the pads of them over her folds. The skin is red, hot to the touch, and she whimpers as she thrusts her hips forward.
"Coming," she repeats, vouce clear with intent. And yes, yes it is. Her labia part as she shrieks with effort, exposing the smallest sliver of wet, dark hair. "I- I'm pushing. I'm pushing! I can't stoppppp."
Despite the bulge of the head in her canal, the crown of which has spread her labia to the point of turning her soft folds bloodless and white (oh, the burn must be delicious, if her cries tell you anything about the sensations she's experiencing), her shaking thighs attempt to snap shut, trapping your hand against her cunt. "Mmmmmphhh!" Her chin hits her chest as she pushes again, grinding her sore and swollen clit against your fingers. "'S it- can you- fuck! Oh, fuck. I need it ouuuuuuut."
The vice grip in her belly releases, the sides of it heaving around the shape of the child as she struggles to catch her breath. "So low," she moans quietly, comtinuing to rock her hips. "God, the stretch-."
And... well, fuck. The stretch. The burn. The teardrop shape playing peekaboo behind her lips. You brush your thumb over her clit, inhaling sharply as she whimpers in a way that let's you know she's preparing to push. "Ohhhh, its gonna come. Its coming. Its-." Her words break off rapidly, and the only sound that escapes her is a wild scream as the head surges forward. She makes an attempt to twist away from you, thighs clamped tightly around your hand as she shrieks and struggles to hold the child in.
"MMMMM, FUCK. BURNINGGGG!"
You press against the bulge of her crown, applying the smallest hint of pressure. With a small hiss, she forces her eyes open and turns to you, panting sharply as the child continues its descent. Her eyes are wild and wet with tears, and you appease her with a gentle smile and a soft kiss as you shift closer to pry her legs back open.
Completely naked, spread, and exposed, she hisses and struggles to no avail. The child sits at half crown; her clit is hard and pulsing against the ridge of its skull, and her labia are shiny with amniotic fluid and what you know to be her own arousal. Maybe you'll have a taste, you muse.
As her belly tightens once more and a groan builds in her throat, you shift your hand just slightly to completely cover her rapidly spreading hole. "Oh, you really can't stop, can you baby?" you croon, experiencing a jolt of arousal as the head surges forward against your hand. "Pushing like that? So... uncontrolled?"
"Get it out," she pleads. "I-holy FUCK, I need it out."
You wait a beat. Feel her push. Feel the head slip further out (nearly to the brow bone that time; you can hear the little noises she makes when it grinds against a sweet spot inside) and feel it retreat. Feel her go limp as she slumps back against the edge of the bed behind her, legs falling open as the bulge has become too prominent to deny.
"Oh, baby girl," you murmur, giving her clit one last gentle stroke to invoke a sleepy smile in return. She must think she's close. Poor thing. The size of the head, as well as the yet unseen shoulders, would disagree. "Is it starting up again?"
"Mhm." Roughly 15 seconds later, she hums again, reaching down to pull her legs back once more. "Mmmmm, here it comes. Oh, its gonna be out soon."
You beg to differ, but you don't dare tell her so.
Another push begins with a ragged scream that rises from the depth of her chest. "ffffFFFFUCK GET IT OUT. I WANT IT OUT."
"Then push," you command. "Be a good girl, and push."
