A male friend of mine years ago proposed a very kinky situation once to me, and at the time I found the thought stimulating. He was interested in sharing a flexible double dong anally with me, and penetrating me vaginally. It seems possible but a bit of a logistical nightmare. We never got to try that out but recently I've found the thought creeping back into my mind. So I am curious, has anyone ever tried something like this before? If so, how was it? If not, doesn't it seem pretty interesting? I'd love to hear thoughts, ideas or suggestions.
