Great story,please continue. Some suggestions maybe she turns him into her slave, Hair slave. Making him prove everyday his devotion and obsession with her amazing Hair. Maybe also next tine he's bound and she's teasing him she braids it and puts it all in his mouth, making him take all of it in until it fills his mouth and cheeks then very slowly removes it. Then she takes that braid, wet from his saliva and ties it tight around his balls and pulls.
