Sadly my first time playing with it was solo; I believe it might be more fun to have a partner play with it and me at the same time. That isn't to say that it isn't fun to play solo as it is. So I tried the toy out on the 1st night of its arrival. I, of course, had to click through all the available vibrations modes first to see how they were and which ones I wanted to experiment with first.
Since it was a solo play, I preferred laying on my back but propped up a bit with my legs spread for easier use of toys, especially little vibrating ones.
I tried getting both sides of the duo tongues in either side of my clit but found it a bit awkward to do with it on and vibrating. So instead of surrounding it, I just used the tip of the largest to guess to "lick" across my clit.
After trying a few strokes hard and a few soft, I found I liked it somewhere in the middle of the 2 ways and just kept brushing it across a few times. Within a minute, I was trying to hold back an orgasm. In the end, I was only able to hold out for a few more before my hips were bucking, and the orgasm kept coming so long as I kept the vibe firmly in my clit.
Now, this being said, I'm not a complete oral fan as it doesn't usually do much for me, BUT if all men's tongues could be like this toy, I would be an addict in a heartbeat.
