Tied up in a kneeling position, an extremely thick vibrator is thrust into her front hole. In addition to this stimulation, a 300cc glass enema syringe filled with glycerin enema solution is inserted into her anus, its vibrations resonating alongside the pulsing vibrator. The sensation from the tip of the enema nozzle transmits the vibrator's waves, rhythmically tickling her anus and bringing forth new waves of pleasure. "Alright, I'm going in. What was it again?" "Please give me an enema." With the vibrator's stimulation intensifying, fresh excitement builds in her rear. "Keep masturbating like this until I say stop. Don't leak anything." "Ah~... Ahh~~..." Unable to fully clench her anus due to the vibrator's relentless pulsing, enema fluid begins to steadily seep out. "My stomach hurts!" The thick vibrator pressing against the thin membrane separating her holes prevents any fecal matter from being expelled. Despite her pained cries, the enema liquid continues to leak. "It's so painful! I can't go!" The thick vibrator is finally pulled from her anus. "Ah, I can't hold it anymore!" At the peak of her agonized scream, a massive fecal mass violently erupts. ※ The woman appearing in this video is not a professional AV actress, but an amateur woman who requested enema training.
