After prepping her loser sub with some extreme face sitting, Sydney decides it's time to remove the chastity device and toy with his dick for a bit. Maybe make him explode and eat his own cum. So far his dick hasn't impressed Sydney much. She doesn't even need more than 2 fingers to jerk him off. Sydney decides to treat this as a science experiment. Can he cum for her while she's sitting on his face, his chest, telling him to kiss her ass, with his feet bound and suspended? Wrapped in tape. His dick and balls getting slapped from time to time. If he cums, he'll have to eat it all. If he doesn't he'll be going back into chastity and he'll be fucked for the rest of the month.
