This follows on from my previous story "First Time with Nipple Clamps" and while reading that first is not essential it will give you a little bit of background on the relationship between myself and Susan.
~~~~~~~~~~~~~~~~~~
We slept long and soundly after Susan's introduction to nipple clamps. The next morning, we relaxed in bed before deciding that we should head off into the nearest city and explore the local Art Gallery.
Having awakened Susan's lust I thought that perhaps there was an opportunity to further explore how far she was ready to go. Some years ago, before Helen had become ill I had bought her a set of Lelo Luna beads, a posh form of ben-wa balls, but she had resolutely refused to even try them out. Now was a chance to put them to good use. I thought that as a starting point a single ball would be sufficient to introduce Susan to the joys of arousal in public.
"I would like you to try something for me," I said to Susan, and with that I handed her the ball.
"What am I supposed to do with this?" she replied rolling it around in her hand and feeling the way that it moved and vibrated.
"It goes in your vagina, it is supposed to help to exercise your internal muscles and also provide you with some erotic stimulation."
"Well, I'll try anything once!"
"Do you want me to put it in for you or would you rather do it yourself?"
"I think it would be more fun for both of us if you did it"
I took the ball from her and popped it in my mouth, firstly to warm it up a bit and secondly to moisten it. I guess that Susan would probably be moist enough to not actually need much in the way of lubrication. Susan spread her legs for me and I placed the ball at the entrance to her vagina, at the same time taking the opportunity to gently stroke her clitoris. As she raised her hips to increase the pleasure I pressed on the ball very gently and it slipped straight in. I followed it with a finger just so that I could adjust its position, but it seemed to have positioned itself by Susan's g-spot, so I left it well alone.
