Retainer job
When anyone with retainers takes their retainers out of their mouth to lick them clean and simply puts them back like nothing happened.
Grace was excited to give her boyfriend a blowjob after she got her braces off, but sadly she had to wear clear plastic retainers all day every single day except for when she was eating. Grace had forgotten she was wearing them while giving him a bj so there was cum stuck in her retainer and since she wasn't wasting and of his (not so) sweet juice. This bitch takes her retainers out to give them a sexy retainer job by licking the fucking cum off of them just to put them back on. What a girl, my dick would be in love if I had her.
