There isn't anything quite like this exhilarating version of 69; its degree of difficulty is very close to 10! The bent over partner reaches far back to orally pleasure while the laying back partner helps brace by holding on to the others hips or thighs. Those best suited for this move are fit, flexible and adventuresome!
On their own, or assisted by the other partner, get into Bridge pose, then reach back one arm and then the other to place the hands in the ready position. Once the laying partner slides underneath, the other can kneel and bend their head back to receive his member. Guys, hold your penis out for comfortable swallowing, and when you're ready for the next move, for heaven's sake, help them out of this one carefully!
