Lay on your back, knees bent leg splayed, feet touching the floor - think stirrups. Insert one end into your vagina, get your partner to mimic your posture, facing you. Insert other end into your friend. One of you starts rocking back and forth, the second person picks up the rythmn too effectively taking turns at being penetrated.
It is a little tricky at first and one of you may need to raise yourself slightly and hold/support the dildo in the center. A third pair of hands is a great addition if you are at ease with group sex.
Beware use of the double dildo rates high on the giggle factor and will have your imagination running wild with possibilities.
