1.
A sexual position involving exactly two males, two females, and one double-ended dildo.

Both females get on their hands and knees and connect to each other via the double penetration dildo.

Both males stand facing each other and are connected to one female each, via the penis to mouth.

To avoid male-to-male eye contact, each male should only look at the female who he is 'connected' to.

4.
A sexual position in which one male is laying down face up (in an overly large bed) while he sexually pleasures four separate women. One female is riding reverse cowgirl, one is sitting on the males face, and the remaining two females are being pleasured by the left and right hand of the male respectively.

Whist in the midst of sexual coitus, the male moves his head to either the right or left to free his head from the vagina which he is currently performing cunnilingus on and exclaims "Connect Four!"
Nearing the point of quintuple climax, Chris removes his head from between his lovers thighs and exclaims:

"Connect Four!"
