Synopsis
“I can’t take it anymore, please get out!”
One day at work, the protagonist experiences intense pleasure during urination in the office bathroom.
Balancing between masturbation and holding back, he barely maintains his sanity and struggles to make it home.
After masturbating at home, he thinks he’s finally relieved, but…
“Wait…is the semen moving?”
This marks the beginning of a creature resembling semen repeatedly invading from his urethra into his bladder and being unable to fully expel it.

Editorial Review
[Alex’s Pick]
This work ventures into distinctly niche territory with its premise of a sentient slime creature inhabiting an unusual anatomical location. It’s a creative, if unconventional, take on the tentacle genre that leans heavily into body horror elements and extreme fetish content. The cross-section tag indicates detailed anatomical illustration, which suggests the artist is committed to depicting the concept with visual clarity rather than leaving it to imagination.
The businessman protagonist provides an everyday anchor to the otherwise fantastical scenario, creating an interesting contrast between mundane professional life and the decidedly non-mundane experiences occurring within. The focus on edging and prolonged stimulation suggests this is crafted for readers seeking extended, drawn-out content rather than quick gratification. The copious fluids tag indicates this work doesn’t shy away from depicting physiological responses in detail.
This is unquestionably a work for experienced doujin readers with established interests in extreme content. It requires comfort with urethral play, tentacles, and cross-section artwork. The premise itself is the primary appeal here—if the concept intrigues you, the execution appears thorough. If you’re seeking character development or nuanced storytelling, this likely isn’t your pick.
For those curious about pushing the boundaries of what BL doujin explores, check this out on Henhenta.
