Let's insert a stainless steel rod into the urethra of a voluptuous girl. The scene becomes even more erotic when imagining her leisurely taking a shower. Have her lift her legs onto the sofa, relax, and generously apply lotion. As you slowly insert it into her urethra, she lets out moans—“Aaaah… ah ah ah ah…” “Ahaaaahnnnnggg…”—quickly succumbing to the sensation. Then, instruct her to stimulate herself by moving it around. “Huh? I’m scared!” she exclaims in surprise, yet gradually grows curious. I light a cigarette, peel off the bath towel, and vigorously massage her body—pinching, poking, circling her clit—cheering on her pleasure.
