(Commissioned by PeachyTanooki.)
"Mario and Bowser are fighting over their Princess again. However, Peach has her own plans to make them get along. By using her charms, she convinces both boys to share their bride in a secret one-time affair.
In this majestic scenery and away from any person to see or hear as she obscenely moans while the two frenemies take turns pumping her full with their love."
