Cuck on LetMeJizz
A husband sits off to the side while another man fucks his wife, and the whole scene is built around him watching. The bull does the work, often bigger and rougher, while the cuck stays close enough to catch every thrust and every moan. Sometimes he's allowed to clean up after, sometimes just left aching in the corner. The charge comes from the power flip, the humiliation, and the wife getting exactly what her partner can't give her.
