Music is often a component when we make love. We listen to Maroon 5’s “Sunday Morning” on Sunday morning while being intimate. The SIRI 2 allowed us to connect with the music a little more. The vibrator is everything you would expect from LELO. It is quite, powerful, made from the highest quality smooth silicone, waterproof and has many vibration speeds and patterns. What makes this vibrator unique is that it reacts to music. When the sound gets going so does the vibration. The concept is neat but we often found songs would end before we wanted them to and there was a long gap till the next song would get going. Lucky for us you can switch the SIRI 2 out of sound-response mode.
