Persistence traning under her white converse sneakers

Description: During a recent session, i was being trampled by both white and red high-top converse sneakers. this experience was kind of a session that served as a significant training exercise, both for the mistress and for me. starting off with white one, with her various unique techniques and practices, allowing her to refine her skills while i learned to endure and respond to the pressure and sensation of the sneakers. sadly the top camera went off due to the setting issue. it didn't take too long until i popped out.
