That sounds like a very good plan, Cristina. Enforcing ‘soft edges’ like that is a really smart way to do it if you can’t hold the edge very well using vibes etc. But I do encourage you to build up, make it more intense as you go.
Worst case scenario you slip over the edge and ruin the orgasm by pulling away instantly (add a quick pussy smack for extra insurance). But as I’m saying all the time, find what works best for you. This is a marathon, not a sprint. Starting out nice and easy is a very good plan!
We look forward to hearing how you get on.
