My BBW wife wears a pair of soft rubber sandals (they still hurt) with really deep treads on the bottom. Combined with all her weight, they leave some awesome marks on my cock. She really gets into the crushing in this one, with some bouncing & balancing on one foot for long periods. After a while you can see my cock visibly flattening out under her weight, as she lifts her foot off. With some grinding & some kicking action, it looks like she's enjoying herself. Finishing off with some bare foot crush & foot job, and the inevitable cum shot.
