+### Handjob

+The atlas examples are direct and simple: the woman faces the viewer between his
+thighs, her hand is the visible contact point, and her face or torso stays behind
+the shaft. In fixed-seed tests, naming `one hand` plus a generic POV camera line

+Works better:
+
+- `POV handjob position`
+- `woman kneels between his legs facing him`
+- `the woman's right hand wraps around the viewer's penis`
+- `her left hand steadies the base`
+- `viewer thighs and pelvis frame the lower edges`
+- `without his hands covering the action`
