Common camera framing
Description: Both partners stand, and the penetrating partner thrusts between the receiving partner's closed thighs from behind: no penetration occurs, the pressed thighs themselves providing the friction. The receiving partner keeps the legs together and nearly straight, which is what closes the channel; the tighter the stance, the firmer the contact. A historically documented practice, it survives today as a niche tease category. Both torsos stay upright, giving the pair a nested, columnar line.
Variations: The same act transfers to lying positions (a spooning arrangement) and to prone; in fetish material the thighs are often oiled. A slight forward hinge at the receiving partner's hips changes the angle without opening the legs.
On camera: Profile framing at hip height, where the between-the-thighs geometry is legible; it appears far more in specialty content than in mainstream scenes.
AI design considerations: Compose two nested standing figures as in a rear press, but register the contact point between the thighs rather than at the pelvis. Closed, touching legs on the front figure are the defining cue.

Image to video (Grind (rocking))
pelvis rocks forward and back through a short arc, contact never breaking, camera is locked on a tripod and does not move.
Motion only. The still you condition on must already carry the position, wardrobe and scene: restating them causes drift.

- thigh_sexbroader
thigh_sex names the non-penetrative act only and is used equally for lying and face-to-face variants; it discards that both partners are standing and that the thrusting comes from behind between thighs held closed and nearly straight.
Actions this position admits
