Double VR Blowjob from Skinny Teen

You've got a skinny sex kitten over at your massage parlor and you're giving her a VR massage from heaven. She's in a blissful state when you finish and she wants to make you feel as good as she does. She pulls out your already hard cock and begins to suck furiously. After she straddles your cock and slides herself down on it, fucking you until you're about to give her a virtual reality cumshot. She wants it in her mouth so she starts to blow you again. How long can you hold out before you need to finish in her tiny little mouth?
