103.5

As with 69, a sexual position in which the participants engage in simultaneous reciprocal oral sex. However, 69 has two participants, while 103.5 has three. This will require some creativity with positioning, although the most likely implementation would have all three suckers lying on their sides - same side (left or right) for each - in a circle. It helps if all three have the same dominant hand (right-handed or left-handed) so they can each lie on the side opposite that hand, leaving that hand free for additional stimulation of one's suckee. Note that this should work equally well for any distribution of physical genders among participants. It should also extend fairly easily to 4 (or more) players. The term was derived from simple math associated with extending 69 from 2 to 3 players - we multiplied 69 by 3/2 to get 103.5.
