A buzzing sex toy gets used on a character’s clit or shoved into their pussy to grind out fast, noisy orgasms. Panels usually linger on the toy pressed between slick lips, twitchy thighs, and the exaggerated tremble lines that sell the vibration. It often shows up as solo masturbation, foreplay before fucking, or a tease that keeps someone on the edge until they’re dripping and begging.
