My Childhood Friend's XL Circumstances

For an entire month, the protagonist has been unable to find satisfaction using his favorite toy, as nothing but an XL size will do. Driven to the peak of frustration and left with no other options, he turns to his childhood friend, Yukihiko, offering a desperate proposition. He never held high expectations for the encounter, but he is completely taken aback when he discovers that Yukihiko’s endowment is far larger than he ever imagined. What was supposed to be a simple arrangement quickly spirals out of control. The once ordinary childhood friend reveals himself to be a dominant sadist who suddenly introduces intense urethral play into their encounters. Instead of a casual favor, the protagonist finds himself deeply loved and thoroughly overwhelmed by Yukihiko’s obsessive and commanding nature. This collection also includes two additional stories featuring beastman-exclusive encounters and frenzied mating dynamics, along with a special extra chapter.
