Two hours each, but as a sort of deferred payment plan

"I'd say two, two and a half hours..." Sam continues.

H clearly intends to continue, but you can't help but blurt, "Each?!" Embarrassingly enough you sound half-hopeful in addition to the mix of outrage, fear, and incredulity.

The boys look at each other, giving you the feeling that you might have missed something, but they turn as one, nodding and smiling.

"But... now? I'm tired," you whine, not noticing your hands replacing theirs on the bottle embedded so firmly in your tingling pussy.

"Well, we could defer the payment," Sam says.

Tom snorts. "Yeah, well, if I'm deferring," he makes finger quotes as he mocks Sam, "I'm demanding interest. Like ten minutes extra per week until the entire time's paid off."

"Yeah sure," you say, though the sarcastic tone might have been lost due to the breathiness of your voice, and the gasp that escapes you as you pushing harder on the warm glass protruding from your sopping cunt.

"Well, if you'd prefer we take all six-hours now..." Sam shrugs.

"N-no," you say, shaking your head and rotating your hips as you start to piston the bottle in and out, gaining a little more depth with each insistent thrust. "Ph-Phillip would wonder where I am."

"No he wouldn't," Tom snickers quietly, earning an elbow from Bill.

"Well then I guess we'll have to defer payment for a few days. Unless someone wants theirs now?" Sam asks.
