Saw you asking about feeldoe, figured I'd share my experiences:
It doesn't really work well as a strapless toy. It's possible, but the amount of attention it requires basically ruins the event. It's far more enjoyable for both parties if it's used inside a barebones strap harness.
When it's used with a light harness, it becomes an awesome toy that provides feedback to the girl involved and also provides some pleasure for her. Sadly it only really works in missionary position, the curve is too much for doggystyle.
thanks for viewing a vid of me and my mistress and adding it to your favs - we are honoured! :D gladly acepting your friendship request hope you enjoy the rest ;) x
