You have to

After a minute you feign disappointment again. Keeping your cock halfway in Beth's mouth, you tell her, "You know, the glistening effect on the penis really helps capture the light. Mind if I go a little deeper to coat it in your saliva?"

She tries to talk with your cock in your mouth which feels amazing, and then she shakes her head no, but you pretend otherwise. "Thanks Beth," you tell her as you push deeper into her mouth. She tries to pull away but your hand on the back of her head prevents it. Eventually you're balls deep and she gags. You pull out and act satisfied.

"Perfect," you refrain from groaning out the word. "Saliva dries fast so might have to do that a couple more times." You thrust shallowly in and out of her mouth for a bit, then make her deepthroat you for a couple seconds at a time. The feeling of her throat convulsing around you almost causes you to cum. At this point she must just accept that since it's already been done, no point in complaining, though she clearly doesn't look happy.

You continue this charade for maybe ten minutes or so before Beth finally pushes your cock out of her mouth and says, "Ughh, my jaw hurts, can we take a break?"

"Oh yeah sure no problem, I actually had another pose I think we can do," you say as you stand up, hard cock swinging back and forth.

Beth shakes her head and raises herself up on her elbows, "I mean, like take a break from the shoot."
