Step-by-Step Guide

The receiving partner lies on their back and raises both legs straight up, keeping them together — the rigid, upright legs resemble a ship's mast.

The penetrating partner stands at the bed edge, holding the raised legs at the ankles — supporting the "mast" while positioning for entry.

Enter at a steep angle created by the vertical legs — the mast-like rigidity straightens the vaginal canal for very deep penetration.

The penetrating partner controls depth by adjusting how far they push the legs toward the receiving partner's head — the mast angle determines stimulation zone.

Maintain the rigid leg position throughout — the "mast" metaphor means keeping the legs straight and tall, not letting them bend or splay.

Keep sessions very brief — the extreme leg elevation demands flexibility from the receiving partner and arm strength from the standing partner.
