By the Ancient Walkers, how many times has Cien-Se cum from the relentless thrusting. And when will Ciona explode again?  \n  \nIt was enough for Cien-Se’s pussy to milk and suck on that shaft while in that orgasmic spasming, because just then, spurt upon spurt of hedgehog cum shoots out into Cien-Se’s body, filling her up, swelling her out, stretching her, ruining her.  \n  \nCiona pulls away, stumbling away and holding onto that shaft. It just won’t stop cumming, marking Cien-Se’s back.  \n  \nAnd the echidna groans as she’s practically showered in molten baby batter, marking her, making it so she’ll need to take the hottest, longest shower of her life ever to have a semblance of being presentable in public again.  \n  \nBut she doubts that’s Ciona’s intention. No, if she could have herself a living cock sock, she probably would, so Cien-se crawls away from her, inching closer and closer to her dropped datapad.  \n  \nBut that’s when one floating hand clamps at her ankle while another one squeezes roughly on the hedgehog’s oozing cock. “Just where do you think you’re going?” Ciona growls, her shoulders slumped forward, her breathing ragged through her mask. “Who the fuck said we’re done.”  \n  \n“I… I have a present for you,” Cien-Se says, her voice shaking almost as much as the rest of her body. She points to the pad. “Luh-let me… open the gate.”  \n  \n“For your programmed little dance doll?”  \n  \n“It may be programmed to dance,” Cien-Se says, gasping as something shifts in her body and cum oozes out, pooling on the tiled floor, leaving her feeling less and less complete, making strange squelching sounds in her stomach. “But it desires cum.”  \n  \nCiona squeezes Cien-Se’s leg tighter. The power of that robotic appendage sends pain shooting up the scientist’s leg. Her fingers are just moments from opening the application and running the program.  \n  \n“So, you tricked me to give you my cum, huh?” Ciona growled. She yanks Cien-Se back, stopping her quickly so her upper body scootches up, her butt rising into the air.  \n  \n“Nobody tries to get one over on me, toots. If you do business with me, you need know I don’t play!”  \n  \n“W… what are you gonna do to me?” Cien-Se says, looking over her shoulder, her eyes pinpricks of awareness, her body tensing up.  \n  \nCiona spreads the echidna’s cheeks, exposing her star. She then hovers her oozing cock over that hole letting the quivering sphincter drink up the oozing cum, winking and slurping it down into Cien-Se’s colon.  \n  \nSo much virility in a single being. Indeed, her ancestors would have venerated Ciona as a god, and Cien-Se would be her high priestess. The thought helps her through as the fat cock head presses against the cum-stained asshole and pushes further, forcing her wider apart.  \n  \nCien-Se’s eyes sparkle in sensation, her body spreading out wider than it was ever designed for as that hot and heavy cock buries itself into her, the cum drooled inside working as an excellent lubricant for the cyborg’s massive girldick.  \n  \nCien-Se drools from her mouth and her pussy, her eyes rolled back, but not all of her sense gone. She reaches out, desperate to grab the data pad, desiring so much to show her boss, her dom, her mistress, the great work she has brought to her.  \n  \nBut Ciona has other ideas.  \n  \nHands move up to the Echidna’s throat, clamping around it, keeping the crawling fuck hole from moving away. Cien-Se croaks out as she fights to breathe. It is difficult as her desire to moan and the gasps that come from each thrust as the cock goes deeper and deeper into her sends shocks throughout her body that make her want to scream!  \n  \nIt isn’t very long before the cyborg hilts into the echidna’s ass, her massive balls slapping against Cien-Se’s thighs. The hedgehog plaps against her through quick thrusts, playing the scientist like a drum.  \n  \n“Maybe… I… will… give… it cum…” Ciona says, huffing as she works hard to fuck the echidna hard. “And when… I do… it’ll be… when I… want! Capice?”  \n  \nCiona lets go of Cien-Se, allowing the echidna to take a deep breath, grasping her neck and nodding. “Ah, hah… yuh… yes, Miss!” she gasps. “Oooh ho ho hhhhh!” Her groans are less coherent after that. She’s so wide and full, and all those very sensitive nerves that run up the rectum fire off as something blasts in and out, back and forth, forever through her!  \n  \nAnd when she thought she couldn’t feel any more, she hears the groan of the crime boss and screams as she’s filled once more with the massive amounts of cum. But this time, Ciona pushes her head down. This time, Ciona keeps herself sheathed into her. This time, she expands and she expands before the hedgehog unleashes her last, goopy drop.  \n  \nAnd when she is done, Ciona pulls out, her cock finally sustained, wiping the sweat from her brow.  \n  \nCien-Se rolls onto her stomach, swollen and spent, cum oozing out of her.  \n  \n“Holy fuck…” Ciona says. “You’re still alive? Heh… guess I picked a good slut after all. Write me up everything about this project of yours, and don’t you fuckin’ tell anyone outside this room about your little cum guzzling clone o’ yers.” She says this, pulling out a cigar, from where?   \n  \n“Gods, I needed that.”  \n  \nCiona tilts her head, hearing those words coming from Cien-Se.  \n  \n“You’re one sick bitch, doc.” The hedgehog says this, chuckling to herself.","series":{"name":"Sonic the Hedgehog","previous":"https://fse.anthro.fr/stories/2265192-honey-x-breezie-1.json","next":"https://fse.anthro.fr/stories/2266868-ciona-and-cien-se.json"}}
