"Well then," She murmurs coyly, arching her drooling cunt into the air. "Come finish what you started."
Tentacles slither toward her, more timid this time as they snake up the inside of her leg. Her gaping pussy trembles as it returns, piercing past her walls and into her womb once again. She aches for friction, grinding against the tentacle. The creature wraps around her upper body and lifts her, suspending her upside down. She grunts, blood rushing to her head.
The monster warbles again as a smooth, round shape travels through its tentacle. An egg, the first of many, is deposited in her womb. It isn't much bigger than a chicken egg, but as more continue to pump into her, she sees her belly stretching around them. Hundreds, if not thousands, press against the barriers of her womb until the beast relents, pulling out of her with a sloppy squelch.
The succubus is placed on her feet once again. This time, the creature doesn't let her go entirely, holding her upright as she steadies herself. She runs her fingers over her lumpy tummy, the squishy eggs inside of her rolling against one another. The beast squeals, mimicking her touch gently.
"You did wonderfully, my darling." She says, placing a hand over the tentacle on her stomach. She didn't have the heart to tell it that her body could not care for its young. A flickering in the corner of her eye draws the attention of the succubus. She frowns and caresses the creature's tentacle gently.
"It seems it's time for you to go, sweetheart."
The creature groans as a force begins to pull it backward. The portal behind it begins to ripple, forcing it to return. The succubus watches with a grimace as the creature is torn from the realm until the seam it entered from disappears in a blink of pale blue light. Save for the unconscious human and the eggs weighing in her womb, no evidence of its presence remained. The layer of slime coating the room is gone, the light stolen, leaving her in a dark, hauntingly empty room.
She approaches the sleeping human, waddling unceremoniously with her plumped belly. She lays a hand on his shoulder, and snaps, teleporting him to his home. Then, she teleports to her lair. It is a realm that belongs to her and her alone, the floor an endless void and a surrounding haze of purple walling them into what is almost a room. In its center sits a bed with satin sheets and a mountain of pillows.
The succubus crawls onto the bed and rests against the plush comfort. With the flick of her wrist, a mirror materializes above her. She stares at her reflection, legs splayed, tits pulling to the side with their weight. Her belly is too swollen to see her pussy, still leaking with the monster's cum. After taking a deep breath, she lays a hand on her stomach and applies gentle pressure. She groans in discomfort but persists, massaging the eggs and clenching her cunt until she feels one push against her cervix. She grunts and pushes, moaning when it finally passes the threshold and enters the canal of her vagina. It's a new sensation, even for her. She wants to reach down and feel it in her walls, but her belly is in the way. She rolls her hips and continues to push until the first egg lands on the sheets below her with a wet "plop."
Again, she pushes on her stomach, and the second egg comes faster. She finds momentum, and the eggs begin to spill from her, flowing with the slick cum left in her womb. Egg by egg, her distended belly shrinks. As soon as she can reach, her hand dives between her legs. She splays her fingers at her entrance, feeling the way she stretches around the eggs as they tumble from inside of her. Curiously, she massages her clit. Lightly, her body still so sensitive from being ravaged by the otherworldly creature. When pleasure shoots up her spine she moans. She continues, pressing into the bundle of nerves and circling her fingers. The orgasm that follows is sudden and almost unsatisfying, she doesn't get the chance to savor it before it's lost to the feeling of eggs relentlessly gushing from her core.
Fortunately for her, an odd feeling begins to build where the eggs lay. It is warm and intense, urging her to push harder, forcing their squishy, round shape to rub a spot inside of her in a new just-right way. She chases the feeling, hunting for it as her hands mindlessly rub the sides of her abdomen, the rippling shape of so many eggs that have yet to come beneath her touch. As the feeling builds, she grows hot, cool sweat beading on her forehead and dotting her body. She could make the bed colder, she could simply remove the eggs, but she didn't want to. Every feeling she had experienced was new and enthralling.
In her frenzy, she rolls onto her stomach, no longer interested in watching herself. She props herself onto her knees and forearms, spreading her legs. The eggs come out slower like this, but it forces their weight against that sensitive spot so nicely that she doesn't care. Her moans seat in the back of her throat, gravelly and almost animalistic. The heat makes her toes curl, her fingers grip the smooth sheets below her and she presses her face into her pillows. The sound of the eggs squelching from her cunt is delectably lewd.
At last, the feeling peaks. It washes her with a burning, inescapable heat as an electric climax takes over her limbs, making her tremble. She falls against the mattress below, forcing several eggs to flood from inside of her at once. She moans and spreads her legs, allowing the pressure of her body to push the eggs out of her. No longer needing to contract muscles, they pass on their own, piling between her thighs until she is finally empty.
In a puddle of beast's cum and unfertilized eggs, pussy throbbing, lays the succubus. Though she is reeling from the sexual energy, satiated and powerful, she does not move. She rolls onto her back and looks at the mess she's made of herself with a smile, contentedly tracing the expanse of her naked body, satisfied. For now...
