I composed the following:

TRIAD 1

Samantha loves both Greg and Tony
Who penetrate both anus and yoni.
As waves of pleasure gorge her flesh,
She writhes and moans, bathed in fresh
And juicy sperm, elixir of love:
Energy from up above.

FOURSOME

His penis plunged inside her yoni,
Evoking gasps from rapturous Tony,
As Peter soared in anal flight
And Greg adored her flesh of white.

When Greg had spilled his sperm of white
On to Amanda's body soft,
Peter came, borne aloft
On wings of love and flame's desire!
Vagina shuddered, passion's fire
Exploding Tony's mighty stream
Of thick and flowing sexual cream,
As sweet Amanda came in torrents
Of ecstasy!
