Her company makes himself into a human foot massage machine, so Ava can rub away the aches and pains of her feet on his chest. He takes off Ava's boots, so she can rub her socked foot on his tongue. He then takes off her sock and lets Ava's bare foot have its way. He takes off her other boot and sock, so now both of Ava's bare feet can get attention at the same time. She rubs her smooth soles on his tongue as he massages her feet, nibbles on them, and sucks her toes. Ava didn't know a human foot massage machine could be so useful.
