[Efuya (Messy)] Futanari Yukie-san and the Secret Urethral Rape

Yukie-san, a stacked futanari MILF who prided herself on being the perfect mother figure, has her arrogance shattered the moment she walks in on young Yuu-kun and her daughter mid-act—and before long the busty dickgirl is bent over her own kitchen counter while the shota milks nearly a full liter of semen from her huge cock and heavy balls twice a day, drinking it fresh or cooking with the rest. But daily milking is only the prelude: she guides him into the characteristic pleasure of urethral insertion, his shaft sliding into her smooth, firm urethra as x-ray close-ups reveal every twitching detail of their connected dicks rubbing inside her. By the final page the two sleep soundly still joined, exchanging semen like an umbilical cord through the night, in no hurry to ever pull apart.
