Foxtress likes to put subs to use while she rests.

Today she is using her sub as a foot rest while she eats crisps and consumes an Energy Drink.

She happens to be wearing some rather spiked boots. She doesn't really care about the subs moans and complaints that as she rests, the spikes dig into him - his job is to be useful and that, right now, means being her foot rest.
