Triple Dipple Triangle

A sexual act involving a man, woman and a double ended dildo. As sexual intercourse ensues the man takes the double ended dildo and puts one end in the woman's anus and the other end in his, then proceeds to carry in with intercourse by inserting his penis into her vagina and thus creating a triangle shape between the three points of entry.

Last night I did a Triple Dipple Triangle with the Mrs and we both came so hard, it was a complete mess.
