Truck

The receiving partner lies on their back and wraps both legs around the penetrating partner's waist, locking ankles behind the back. This leg lock pulls the penetrating partner's pelvis close and creates the tight, connected base for the grinding motion.

The penetrating partner positions their weight on their hands (placed on either side of the receiving partner's shoulders) or forearms, keeping the torso slightly elevated. This allows room for the hips to perform the driving motion without crushing the receiving partner.

Enter at a straight-on angle — the wrapped legs create a slight upward tilt of the receiving partner's pelvis, directing penetration toward the anterior wall. The close pelvis-to-pelvis contact is essential for the grinding motion to work.

The penetrating partner uses a forward-driving hip motion — pushing the pelvis forward and down in a grinding arc, like a truck driving forward. The motion is deliberate and powerful, not fast. Each grind should feel like sustained, deep pressure.

The receiving partner can control the angle by adjusting how tightly they squeeze their legs — tighter squeeze = more friction and tighter fit; looser squeeze = easier movement for the penetrating partner. The leg squeeze is the throttle.

The grinding motion should maintain constant pelvis-to-pelvis contact — the Truck is defined by continuous friction, not in-and-out thrusting. The penetrating partner should feel like they're grinding against the receiving partner's pubic bone throughout.
