the wan2.2 model performs well on the 'nipple fuck' tag, even though its resolution is only 640x432.(nipple insertion,nipple fuck:1.6),The girl remained completely still, while two men thrust their penises continuously into their nipples. Finally ejaculate through the passage of the nipple.The first paragraph of the video did not perform very well due to my failure to debug the prompt words properly, but after modification, the model's understanding of nipple fuck in the following two videos has improved significantly.
