The somewhat alarmingly named Satan-Denma 28 Vibrator is here to introduce you to the dark arts of a massager wand vibe, that classic choice for couples in Japanese porn. With seven vibration patterns and four power levels, you can explore a total of 28 types of vibration. If you or your partner want to squirt, this toy and its round head is designed to induce precisely this and, importantly, is splash-proof, so those bursts of vaginal fluids won't damage the vibe.
