Xstuffing presents an intense exploration of urethral cockstuffing. A mysterious figure, unidentified but eager, takes the plunge into extreme pleasure. A large, black pen, meticulously lubed, disappears inch by inch into the tender urethra, stretching the delicate tissue. The anonymous star gasps and moans, a mix of pain and ecstasy playing across their face as they push through the limits of their comfort zone.
