[OKINA] Nyoudou Kakuchou Choukyou Kiroku (Iwasaka Haruko) [Project Valvrein]

Haruko, a petite girl with twintails and a red collar, endures a relentless urethra expansion as a massive device forces her body to stretch beyond its limits, her cries echoing in the cramped room. She is bound by bondage straps, her trembling form highlighted by the pulsating pressure on her urethra, while a handheld controller offers a chilling promise of continued torment through the night. Project Valvrein presents this vivid doujinshi as a stark record of forced pleasure and humiliation, where the relentless insertion and ensuing urination become the focal point of her helpless surrender.
