It's always been fairly easy for my wife to orgasm via clitoral stimulation - but it wasn't until she started with blended orgasms that she felt truly fulfilled.
We learned how to do this when she confessed that she needed something inside to help her get off using a vibe. This led us down the road of rabbit vibes and dildos. Now we routinely use a combination of toys to give her an orgasm. After learning the blended orgasm technique she was able to transition to multiple orgasms as well.
He latest preference is now for anal play thrown in - so we're on to triple plays now!
