Luna wants to be your good girl and make her throat useable for you. She starts warming it up with her fingers and sliding her fingers right down her throat and letting her gag spit become lube. When she is all drooly, she starts pushing your dick down her throat and just letting the spit get everywhere. All over her chin and onto her tits and underwear. Your dick is too big and she's finding it hard to get it all down, even with all that spit being used as lube. She will continue training to be a good girl for you.
