reverse_wheelbarrow_position
piledriver_position

I read the wiki pages for both and can't tell the difference between them. The receiving partner has their shoulders on the ground, the peneterating partner peneterates vertically while standing

What is the difference? I want to tag this position because it's important to me

They are two very similar positions but with a slight difference.

• The piledriver_position has the penetrating partner lift the penetrated partner almost vertically off the ground, leaving only their shoulders or upper back touching the ground and their knees commonly bent over their heads. The penetration then occurs with a crouched stance and a downwards thrusting motion, almost horizontally parallel with the partner below.
• The reverse_wheelbarrow_position has the penetrating partner lifting the penetrated partner into a similar position (akin to lifting a wheelbarrow), but the penetration occurs with a standing position and either a downward or forward thrusting motion.
