Yes, Bill does.

Marie is applying the perfect amount of pressure, and you can feel your orgasm building. You bite your tongue and try to picture the grossest things you can imagine, but you know it's hopeless. You glance at the hourglass and it's over halfway gone. You watch as the sand slides through, but when it's about three quarters gone, you can't hold out any longer and start spurting out over Marie's hand. Bill clearly hasn't cum yet, as Marie redoubles her effort on him. As the last of the sand drops down and Chloe calls "Time!" Bill's arms go up in triumph.

You breath a sigh of relief knowing that the boys won the challenge, even if you only get to watch as Bill enjoys the spoils of victory. He wastes no time in divesting Marie of her bra, and you enjoy the sight of the scrumptious breasts you got to feel earlier. As Bill lowers his head and sucks her nipple into his mouth, Chloe turns the hourglass over.

With the view of Marie's breasts mostly blocked by Bill's head as he moves back and forth sucking and licking them, you turn your attention to her face. Marie's eyes are closed and her head is leaned back on the couch as she enjoys his ministrations. She gasps and opens her eyes suddenly, and you suspect that Bill bit her nipple. As he continues, she again relaxes and you feel yourself getting hard again.

All too soon, Chloe calls time and everyone returns to their seats. Marie reaches forward to spin the bottle, her breasts swaying enticingly. You notice a few red marks from Bill's attentions. She raises her eyebrows at you and you realize the bottle has already stopped spinning.
