anvil position
A front entry sex position that's similar to missionary position, except the character being penetrated has their legs up towards the partner's head, instead of spread or wrapped, while the top is kneeling instead of lying down.
The position can be also very similar to arch position and piledriver position, where the penetrated character not only has their legs up, but actually only their shoulders are on the ground.
If penetrating character is flipped, it becomes reverse_anvil_position.
Similar position where penetrated character is flipped: jockey position.
Similar position where partners are flipped: reverse missionary position.
