The Head Keeps Slipping Back
He was on his knees on the bamboo mat, thighs trembling, ass pushed back as far as it would go. His huge belly hung low and tight between his spread legs, contracting in long, heavy waves. Every contraction made the buttbaby’s head move forward through the massively prolapsed tissue — but the moment the wave eased, the head would slip back a little, the swollen, everted rectal lining clinging to it like it didn’t want to let go.
The prolapse was enormous. Thick, dark red, shiny and swollen, completely turned inside out around the dark-haired head that kept trying to crown. With every push the head would advance further, stretching the already ruined hole wider, but as soon as he stopped bearing down it would recede again, the puffy mucosal ring pulsing and twitching around the widest part of the skull.
After one particularly strong contraction he gasped and shook his head, voice breaking.
“Fuck— it’s burning so bad. It hurts… I can feel it stretching too much. I’m scared to push harder. What if it tears?”
His partner’s hand stayed steady on his lower back, fingers spread wide, thumb moving in slow, grounding circles over the sweaty skin. But the sight in front of him made his cock throb painfully hard inside his pants.
The prolapse was stretched so thin around the baby’s head it looked almost translucent in places — shiny, strained, the dark wet hair of the buttbaby clearly visible where it was trying to emerge. The swollen tissue clung desperately to the skull, pulled so tight it seemed like it could split open at any second. The contrast between the thick, puffy prolapse and the way it was being forced to open even wider around the head was obscene. His partner stared, breathing heavier, cock twitching hard at the dangerous, stretched-out sight.
For a few long seconds he didn’t say anything. He just watched the head sit there, partially crowned, the prolapse looking like it was seconds from ripping around it. The visual made his stomach tighten with a hot, twisted rush of arousal.
Then the worry cut through.
“Shit… yeah. It really does look like it’s about to tear,” he admitted quietly, voice rough. His hand rubbed gently up and down the man’s back. “Okay, baby. Stop. Don’t push if it hurts that much. We’re not forcing anything. Just breathe through it. Rest if you need to. I’m right here with you.”
He whimpered, the head still partially out, the prolapse pulsing and twitching around it. His own cock hung heavy and leaking beneath everything, a steady string of precum dripping onto the mat. His balls were tight and full, swinging slightly with every shaky breath.
The next contraction started building slowly in his belly. He felt the pressure rising, the deep ache spreading through his pelvis. His partner stayed close, one hand still on his back, the other resting lightly on his hip now.
“That’s it… I can feel it coming. You don’t have to push hard this time. Just let your body do what it wants. If it’s too much, just breathe through it. I’ve got you.”
The contraction peaked. He couldn’t stop the low, pained moan that escaped him as he bore down instinctively. The head moved forward again — slower this time — stretching the already swollen prolapse even wider. The tissue pulled thin and shiny around the widest part of the skull, the dark hair plastered to the baby’s head clearly visible, framed by the thick, everted rectal mass that looked dangerously close to giving way.
His partner watched, heart hammering, cock rock hard, but he kept his voice calm and steady.
“Just like that… breathe, love. I’m right here. We’ll go as slow as you need.”
The head sat at its absolute widest point yet, the prolapse stretched to the limit around it — shiny, thin, and trembling. He trembled beneath his partner’s hand, panting through the intense burn, too scared to push any harder, caught right in the middle of the contraction with their baby’s head fully crowned and visible between the swollen, prolapsed lips of his ass.

Remy couldn’t look away.
Silas lay on his back with his legs spread wide, his huge, tight belly glistening with sweat. Droplets ran down his hairy chest and over the curve of his stomach. His face was twisted in effort, breathing hard through parted lips.
Remy leaned over him, one hand gripping Silas’s thigh, the other gently stroking the side of his swollen belly. The younger man’s eyes stayed fixed downward — locked on what was happening between Silas’s spread legs.
Silas’s hole was already stretched wide, red and shiny. With every push, the dark, wet crown of their baby’s head slowly emerged, forcing him open even more.
“Fuck… I’m watching,” Remy whispered, voice low and shaky. “Silas… I’m watching our son coming out of your ass…”
Silas groaned loudly, fingers clutching the sheets. Another contraction rolled through him and the baby’s head pushed forward a little more, the skin around his hole stretching tight and pale.
“Remy… it hurts…” Silas gasped, but there was something else in his voice — something hot and desperate.
Remy swallowed hard. His cock was throbbing. He couldn’t stop staring at how Silas’s hole was opening around their child’s head, how the skin strained with every push. It was the most intimate and arousing thing he had ever seen.
“You’re so fucking beautiful like this…” Remy breathed, leaning in closer until his face hovered just above Silas’s belly. “Push for me, baby… I want to see the whole head come out of your hole.”
Silas let out a low, guttural sound and bore down hard. The baby’s head slid further out, forehead and nose now visible.
Remy watched everything with wide eyes, one hand still gripping Silas’s thigh, the other slowly tightening as if he wanted to help pull their son into the world.
“Yeah… just like that…” he whispered. “Give birth for me, daddy…”

Part II: Incident Report – Subject 14 (USN-64-089)
If you want to see the full version of this photo, join me on Discord 🔥
Classification: Top Secret / Project AEGIS-M
Date of Document: August 14, 1964
Location: Unspecified Sub-Level Facility, Bethesda Naval Medical Center
Subject: Petty Officer 3rd Class, Age 24 (U.S. Navy)
Case Background
Subject 14 was intercepted during a deployment in the North Atlantic after reporting to the ship’s medic with symptoms originally misdiagnosed as an advanced, atypical abdominal tumor accompanied by acute lower-GI hemorrhaging. Upon transfer to a secure facility, palpation and emergency radiographic imaging revealed a fully gestating, 36-week fetus nestled within a secondary, retroperitoneal uterine structure.
The objective of the medical directorate was to determine if this was a spontaneous mutation, a chemical byproduct, or a biological weapon threat. The following is the raw audio transcript recorded during the active labor phase.
Transcribed Audio Log: Delivery Room 4-B
** Dr. Vance (Lead Surgeon):** ...Utero-rectal contractions are narrowing to ninety-second intervals. The external sphincter is resisting the descent. I am moving in for manual dilation. Collins, secure his legs. ** Subject 14:** (Loud, ragged screaming) Ahhhhh! No, stop! Stop, it’s burning! God, it’s tearing me open! ** Dr. Vance:** (Stern, booming voice) Quiet down, Petty Officer! Cut the noise right now! This is a classified military operation, not a civilian ward, and I will not have you screaming like a raw recruit. You are hyperventilating and ruining your respiratory efficiency. Breathe through your nose and lock it in! ** Subject 14:** (Choking back a sob, heavy shuddering breaths) Yes, sir... yes, sir... but it feels... ** Dr. Vance:** Listen to me. The internal pathway is expanding, but the anatomy is narrow. I am applying manual lateral dilation to the external ring to ease the passage. It is going to stretch, and it is going to hurt. Now, free his right hand. Petty Officer, bring your right hand down here. Work with me. Use your fingers to assist the dilation. Keep the canal open. ** Subject 14:** (Deep, guttural groan of intense strain) Ohhhhh... gasp... I’m trying... I’m holding it open... ** Dr. Vance:** Your left hand stays clamped on your upper abdomen. Press down on the fundus to brace the internal sac. Push with the contraction, not against it. Do you understand your orders? ** Subject 14:** (Screaming through grit teeth) Yes, sir! Uhhhhh— ** Dr. Vance:** Push! Don't waste your breath screaming, channel it into the lower pelvic floor! Push! [RECORDING INTERRUPTED – TAPE REEL CHANGE – 18 MINUTES OMITTED] ** Dr. Vance:** ...re-engaging audio. The fetal scalp is now visibly presenting. The dilation is holding at maximum capacity. ** Subject 14:** (Continuous, high-pitched agonizing strain, muscles visibly trembling) It’s stuck... it’s stuck... it’s too big... ** Dr. Vance:** Don't you dare start panicking now, Petty Officer! Look at me! The head is crowning. The heaviest resistance is right now. If you lose focus, the tissue will collapse and crush the specimen's cranium. ** Nurse Collins:** Doctor, the cranial diameter is breaking through the rectal shelf. The pressure on the perineal floor is extreme. ** Subject 14:** (A long, breaking shriek that distorts the microphone) AGIHHHH! It’s out—it’s coming out! ** Dr. Vance:** Keep your right hand there! Do not let go of the posterior rim! Support the crown with your fingers while I ease the forehead past the sphincter. Steady... steady... Push one more time! Give me everything you’ve got! ** Subject 14:** (A deep, breathless, animalistic grunt of maximum physical effort, followed by sudden, sharp gasping) ** Dr. Vance:** The head is entirely clear. External rotation is beginning. Tissue elasticity has held without structural failure. Collins, prepare the suction and the sterile receiving kit immediately.
Post-Natal Involution and Isolation – Subject 14 (USN-64-089)
1. Physiological Involution and Reversal
Following the events of August 14, Subject 14 was placed into a chemically induced state of metabolic deceleration to monitor the structural collapse of the secondary reproductive system. The speed of his internal recovery bypassed all standard medical predictions.
Anastomosis Closure: Within 96 hours post-delivery, the utero-rectal fistula began an aggressive process of muscular involution. The smooth muscle fibers that had expanded to accommodate parturition contracted rapidly, effectively sealing the corridor between the lower rectum and the retroperitoneal cavity. No surgical closure was required; the body autonomously locked down the pathway.
Structural Healing: Micro-scans of the anal canal showed zero permanent scarring or incontinence. The hypertrophic stretching observed during labor left no trace, proving the tissue possessed a high-velocity cellular regeneration capability specifically adapted for this reproductive cycle.
2. Status of Specimen 14-A (The Infant)
The product of the gestation, designated Specimen 14-A (Male, 3.4 kg at birth), remains under continuous evaluation in a sterile, low-stimulus environment.
Karyotype Analysis: Preliminary chromosomal testing indicates a completely standard human set of 46 chromosomes (XY), with no visible structural anomalies or zniekształceń wywołanych (deformations) induced by external pathogens or radiation.
Serological Compatibility: Cross-matching blood types and advanced analysis of antigens (ABO, Rh, and MN blood group systems) confirmed full hematological compatibility with Subject 14 as the biological parent. However, the source of the second cellular component required for conception remains an unresolved enigma. The subject has consistently refused to provide any names or details regarding sexual contacts prior to his deployment.
Development: Specimen 14-A exhibits advanced motor skills for its age bracket, alongside highly elevated levels of the same unique endocrine markers found in the father. It is the directive of the Board that the specimen be raised entirely within the Facility-7 nursery network for long-term evolutionary tracking.
3. Institutional Security Measures ("The Wipe")
To ensure absolute containment of Project AEGIS-M, the following counter-intelligence protocols were executed between August 20 and September 5, 1964:
Erasure of Identity: All personnel files, naval enlistment records, and medical/dental charts belonging to the subject were permanently incinerated. His birth certificate in state archives was replaced with a standard mortality record indicating a fatal training accident at sea.
Containment of Witnesses: The ship’s medic from the North Atlantic deployment who initially logged the "abdominal tumor" was reassigned to an isolated weather station in the Aleutian Islands under a lifetime non-disclosure directive under threat of court-martial.
Current Asset Status: Subject 14 has adjusted to residency within the New Mexico compound. While his physical health has completely restored to pre-pregnancy military standards, he exhibits symptoms of deep psychological detachment and apathy. He is permitted supervised movement within the sub-level laboratories, but remains permanently barred from any contact with Specimen 14-A or the outside world.

Alexey: God, you look absolutely insane like this. I can’t even look at you right now without wanting to pull you straight out of that chair.
Dmitry: Then stop staring and do something about it. You’re making me hot just watching you lose your mind.
Alexey: I’m just taking it in. We spent fucking years hiding in dark corners, dreaming about a place where we could just exist without looking over our shoulders. We wanted this life so bad it hurt. And now look at you, shirtless in our own room, completely heavy with my kid. It’s really my baby boy inside you, Dima. You’re literally carrying my mark.
Dmitry: You’re a possessive bastard, you know that? But yeah. He’s ours. And right now, he’s kicking like crazy because he can probably feel how fast my pulse goes every time you look at me like that.
Alexey: Good. Let him learn early who runs this place. Now come here and shut up.
