Whenever We Go Shopping Together, She Requires Me To Stay 2 Steps Directly Behind Her, Unless There Is

Whenever we go shopping together, she requires me to stay 2 steps directly behind her, unless there is a door for me to hold open for her. I follow her around everywhere, carrying her purchases in my arms. I am to keep my eyes fixated on her only, which makes for a very tight cage as she casually strolls right in front of me. Occasionally I can’t help but moan at the discomfort. Her response to the sound is a soft, smug laugh and perhaps a one-handed smack on her own backside.
