Mistress Serena did not like the cheap sneakers her husband had bought her. She had told him which ones to buy but he thought he was smarter and bought low quality ones. She went to the gym with them and when she came back, they were stinky and smelly. And she used them to punish him. She also made him smell and chew her stinky and sweaty socks as well before making him go back and buy the ones she wanted.
